Functional Areas
Mechanical front-wheel-drive (MFWD) front axle provides traction on demand
Limited-slip, heavy-duty MFWD front axle with mechanical control provides engage-on-the-go capability under normal load conditions.
The limited-slip solution unlocks the true potential of the axle allowing for increased drawbar pull and improved traction, even when one tire is in a slippery condition. This ensures the operator gets the required torque to the ground for the applications demand and frees the tractor to break out of a potential rutty situation, leaving producers with cleaner fields and decreasing the need for pulling chains. The MFWD front axle also reduces wheel slippage with less tractor ballasting for reduced soil compaction, increased fuel economy and longer tire life.
The MFWD centerline design provides excellent maneuverability around the worksite and more crop clearance so producers aren’t driving down their crop or profit. Additional versatility is proven when wheel treads are adjusted and with 6 degrees of caster angle and 55-degree turn angle, which results in a shorter turning radius and plenty of horsepower to turn around in tight places. 10 degrees of axle oscillation follows uneven terrain allowing for consistent performance and comfortable ride.
Axle oscillation also reduces the stress and maintenance cost on the axle spindles because loads are consistently spread across the entire axle. The centerline design also eliminates the need for drive shaft universal joints that require regular maintenance. Three grease points are conveniently located to minimize maintenance time while maximizing front axle performance.
The MFWD engagement lever is located on the left-hand side of the operator. In addition, for the operator’s convenience when MFWD is engaged an indicator light will appear on the dash.

Differential lock for better traction
Operators can confidently go into wet and muddy conditions with greater expectation of getting out with the standard differential lock. Differential lock allows power to be applied equally to both rear wheels for better traction when wheel slip occurs.
The foot-pedal engagement is located on the right side of the platform which makes it easy to release the clutch pedal and engage the differential lock at the same time. The lock automatically disengages when traction equalizes.
Base Equipment On: 5E and 5E Specialty Series
Inboard planetary final drives reduce stress on gears and shafts
Inboard planetary final drives distribute rear axle loads over three points for reduced stress on individual gears and shafts. Operators can expect longer life with less service, which means maintenance time is replaced with profitable production time.
Inboard design also permits a wide range of wheel tread adjustments so operators can accomplish more with just one tractor by having the ability to custom set tire treads to meet the specific demands of a variety of tasks.

John Deere PowerTech™ 4-cylinder diesel engines create outstanding performance, durability, and the best operating experience
John Deere-designed and -manufactured diesel engines provide excellent torque, fuel efficiency, and durability.
The heavy-duty cylinder block provides greater strength and rigidity, which is what allows these tractors to perform in ditches, ravines, and other less-than-ideal conditions.
The statically- and dynamically-balanced crankshaft reduces engine vibration. The operator’s body absorbs less vibration allowing them to stay attentive and consistent throughout the work day.
High-ring piston design reduces the non-usable air in the combustion area of the cylinders for improved fuel efficiency and combustion so the most power is received from every engine stroke. Ni-resist inserts reduce ring groove wear, which would lead to less effective combustion, so operators have an engine that is proactive for performance.
Tee-pee connecting rods provide increased strength and durability of both the connecting rod and the pistons, which allows operators to run in a wide array of conditions.
Keystone-shaped top rings move slightly in the groove to clean the carbon deposits, conditioning the tractor to remain ready to work. Plasma-coated for reduced drag on cylinder wall and increasing overall tractor life.
Cylinder liners dissipate heat to prevent cylinder distortion and rapid ring wear, allowing you to see consistent performance. Certified John Deere technicians can easily restore engine to the original specifications after many hours of hard operation. This extends the life and performance of the tractor.
Full-pressure lubrication system ultimately protects your wallet from maintenance costs. The underside of each piston and piston pin is sprayed with cooled and filtered oil, which eliminates excessive heat for longer life. The full-flow filter allows the cleanest fuel to be delivered to the engine for maximum performance and filter bypass so the tractor will never be starved for oil due to an exhausted filter.
Engine oil cooler provides additional engine oil cooling, allowing operators to run in severe applications, reducing the likelihood that the engine will overheat.
A neutral start switch ensures operator and bystander safety, the right-hand gear shift lever must be in the park or neutral position for the engine to start.
Electric fuel shutoff allows the operator to easily turn the tractor off with the key, just like an automobile. A solenoid on the injection pump that permits using a key instead of a push-pull cable to shut off the engine. Electric fuel shutoff does not allow bypass starting. If an attempt is made to bypass start the tractor, through the use of electronics, the electric fuel shutoff will not allow the engine to start.
A dry-type air cleaner has a dual-element design for added engine protection against dust or debris from entering the combustion chamber, ensuring performance time opposed to shop time. Reaching the filter for service is easy, the operator simply unlatches three clips. A restriction indicator light on the dash alerts the operator when servicing is required to save potential engine repairs.
A single-element fuel filter partners up with the hand primer and water sediment bowl to deliver the complete package. John Deere designed specifically to meet the needs of John Deere tractors, the fuel filter provides a hand primer to prime the system for an easy fix for any operator who gets busy working and forgets to fuel up. The water separator stores water separated from the fuel to protect from the cost of fuel injection pump failures due to water contamination.
The automotive-style fan drive belt drives the fan, water pump, and alternator. The belt features a self-adjusting spring tensioner, which eliminates service tasks, the need for a wrench, and extends the life of the belt because it is always in the correct adjustment.

Understanding engine horsepower
5E 4-Cylinder Tractor engine
How is engine power measured?
John Deere engineering uses a precise procedure to measure engine-only power levels. The 97/68 EC standard is required in the European Union (EU) as an emission test, so there is some relation to the power a tractor has as a whole functioning unit. However, the procedure requires only that a production engine and radiator are used on a dynamometer test. This 97/68 EC standard is widely used in Europe for various regulations.
Do all equipment manufacturers use the 97/68 EC standards?
No. There are several ratings systems that may be used by other brands.
Do all ratings systems get the same horsepower results?
No. There are many different results depending on the ratings system used and the procedure requirements. It is important to know the standards used for the measurement when comparing horsepower values.
Does the updated numbering system reflect the engine or power take-off (PTO) horsepower?
The updated name and numbering scheme reflects the approximate engine horsepower as measured by the 97/68 EC International Organization for Standardization (ISO) standards.
Understanding engines
The engine is one of the most important factors to consider when looking for a tractor. The engine determines how much work the machine can actually do since the engine provides power to the other systems of the tractor.

The updated name and numbering scheme reflects the approximate engine horsepower as measured by the 97/68 EC (international organization for standardization [ISO]) standards.
Engine horsepower
What is horsepower (hp)? Officially horsepower is a unit of measure that is nearly equivalent to the amount of energy required to lift 550 pounds, one foot, in one second. There are several different types of hp including: engine, power take-off (PTO), and drawbar.
Engine horsepower is typically reported in tractor specifications. But even among the engine hp numbers there are differences depending on where horsepower is measured and how it is measured. Across manufacturers, there are several different types of engine horsepower reported and different standards being used for measuring horsepower.
Agricultural equipment manufacturers typically report horsepower as either 97/68 EC or society of automotive engineers (SAE). These two measurements take different items into account when measuring horsepower. Both are widely used across the industry but have different requirements for what equipment needs to be installed and running during the testing procedures.
The 97/68 EC standard requires that only the engine and radiator are used for the test. The engine is tested prior to being installed in a tractor.
The SAE standard for gross engine hp requires that just the engine be tested. The engine is tested prior to being installed in a tractor.
In addition, there are different types of engine hp that could be reported. Typically, manufacturers report one of these two types of engine horsepower:
- Gross hp – This is just engine hp. It does not take into account accessories or transmission losses.
- Net hp – This is engine hp including losses for some accessories, but not the transmission.
Torque
There is a relationship between torque, hp, and engine rpm.
Torque = (hp x 5252) / rpm
Can a car with 101 hp do the same amount of work as a tractor with 101 hp? No. The big difference between the two is torque. Cars run at nearly twice the rpm of a tractor.
Getting the power to the ground refers to torque. Torque is a force that produces or tends to produce rotation or torsion or a twisting force. Simply put, torque is the useable power that can be achieved. The more torque you have, the more lugging ability is available. And more torque equates to more load carrying capacity.
Example:
Tractor A
Engine hp: 95 hp
Engine rated speed: 2200 rpm
Torque = (95*5252)/2200
Torque = 226.8 lb-ft (307.5 Nm)
Tractor B
Engine hp: 95 hp
Engine rated speed: 2600 rpm
Torque = (95*5252)/2600
Torque = 191.9 lb-ft (260.2 Nm)
Tractor A has more torque, more lugging ability, and more load carrying capacity.
Engine serviceability
Ease of access for daily service points for the engine should be considered when comparing engines. The engine oil check should be easy to access from the ground. Some manufacturers allow access to the engine oil dipstick without opening the tractor’s hood.
While most manufacturers have warning lights and/or audible signals for engine problems, it is still important to ensure that you know what the warning lights mean. Typically a description of the warning lights can be found in the tractor’s operator’s manual.
For long term owners or those seeking higher re-sale values on older machinery, a wet-sleeved engine may be beneficial. Engine cylinders can have wet-sleeves encasing the cylinders, providing easier long-term maintenance for that engine. A wet-sleeve cylinder liner can be completely removed and replaced if a cylinder replacement is necessary. A parent bore engine would require the technician to bore out a larger space for the new cylinder or in some cases replacing the entire engine block, resulting in a higher cost for repair when compared to a wet-sleeve engine.
Turbocharged or naturally aspirated engines
There are two advantages to a turbocharged engine over a naturally aspirated engine:
- Turbocharged engines create more power
- Turbocharged engines provide more consistent performance regardless of air density or altitudes. A turbocharged engine brings more air into the engine and creates more power for the same engine displacement.
Simply put, a turbocharged engine can create more power than a similar sized naturally aspirated engine.
Is the engine structural?
In compact utility tractors and utility tractors, the engine is often structural. This means the engine block serves as the tractor frame, and there is no additional frame. This design requires a robust engine block that can withstand the stress of the various activities the tractor is required to do. In general, larger tractors in more demanding tasks have full or partial frame designs for increased durability.
Engine displacement and cylinders
Engine displacement is the volume covered by all the pistons on the inside of the cylinders. A smaller displacement engine can provide the same horsepower as a larger displacement engine. This is done by increasing the engine rpm to create the power or by adding a turbocharger.
A higher engine-rated rpm results in more engine wear because the engine turns more times per second to do the same amount of work as a lower-speed engine. Typically larger displacement engines require lower rpm to get the power.
The horsepower-to-liter ratio is a good tool to use when comparing two engines. The higher the horsepower-to-liter ratio, the harder the engine is working.
Example:
Tractor A
Engine hp: 95 hp
Engine displacement: 4.5 L
Engine rated speed: 2200 rpm
95/4.5 = 21.1
Tractor B
Engine hp: 95 hp
Engine displacement: 3.77 liters
Engine rated speed: 2600 rpm
95/3.77 = 25.2
Tractor A’s engine is not working as hard as Tractor B’s engine to achieve horsepower.
Adapt to a wide variety of implements with a Category 2/1, 3-point hitch
The 5E Series Tractors’ Category 2/1, 3-point hitch adapts to a wide variety of implements.
The 3-point hitch has plenty of lift capacity to handle heavy ground-engaging integral implements, such as planters, sprayers, and field cultivators.
It also has a 1530 kg (3374 lb) lift capacity at 610 mm (24 in.) behind hitch lift balls.
Hitch adjustments can be made quickly and easily with the standard mechanical 3-point hitch.
Category 2 balls are installed at the factory and come with the tractor. Category 1 balls are ordered through Parts.
Base Equipment On: 5E Series
Top-link draft sensing provides consistent results every time
The top link is the first part of the tractor to experience an increase in draft load with the lighter, short-coupled implements typically used with tractors of this size.
Draft sensing allows the hitch to quickly raise or lower, as needed, to control the load on the engine. It also reduces the need to downshift into a lower gear when operating in a rough spot, simplifying operation.
Draft sensing helps to keep implements operating at a constant depth to avoid the washboard effect when box blading or evenly break ground for consistent plant emergence.
The draft response is adjustable using the draft control lever to match the operating conditions and implement being used. The rockshaft position control lever has a float position for implements with skid shoes or depth gauge wheels that carry implement weight.
Base Equipment On: 5E Series
Hitch adjustments are easy with the mechanical 3-point hitch
Raise and lower implements with the precision of 3/8 in. (10 mm to 12 mm) by using the rockshaft control lever. The operator can also adjust the speed at which an implement is lowered by adjusting the rockshaft rate of drop.
The rockshaft control lever also allows lift links to be adjusted for lateral float, enabling implements with gauge wheels or skids to follow the ground contour. That means, operators won’t have to spend time adjusting or readjusting to get the gauge wheels or skids to follow the ground.
The adjustable depth stop provides consistency when lowering the hitch. Each time the position control lever is pushed forward, it stops where the depth stop has been positioned – a value to anyone who desires a consistent, level ground, like when preparing a seedbed.
The center link can be set in one of three positions to accurately set the implement position and draft sensing.
Adjustable sway chains can be adjusted to adapt to a wide variety of implements, and the right lift link adjusts without tools for added convenience when leveling implements.

Standard independent 540 rpm rear power take-off (PTO) performs well in normal or heavy applications
Unlike most competitive tractors of this size, customers receive all the power and torque they paid for. The 540 rpm PTO speed is achieved while operating engine at rated speed so the full advertised horsepower can be delivered in any application.
An easy to use mechanical lever engages and disengages the PTO independently of the transmission traction clutch and operator’s can manually feather the PTO lever for smoother engagement. When the PTO is engaged, a light on the instrument panel is illuminated. Adding to operator safety, the tractor will not start with the PTO lever engaged, an alarm sounds if the operator attempts to leave seat with PTO engaged, and the PTO shaft is protected by a hinged shield.
Base Equipment On: 5303, 5403, 5225, 5325, 5325N, 5425, 5425N, 5525, 5525N, 5525 Hi, 5603, 5625
Save fuel in PTO applications with the optional 540/540 Economy PTO
The 540/540 Economy PTO allows operators to select the engine rpm needed for their power take-off (PTO) application.
The economy position provides 540 rpm to the PTO at 1700 engine rpm. The 540 Economy is ideal for any PTO application, from running a mower conditioner to a baler or a cutter, where full horsepower is not needed.
Operating at lower engine rpm decreases fuel costs during tasks. The overall operating experience improves because there is less noise and vibration for the operator.
A lever allows the operator to simply change between 540 and 540E when conditions merit the opportunity to save fuel without affecting performance.
For heavy-duty operations requiring maximum PTO power, the PTO shift lever is placed in the 540 position, the PTO is engaged, and the engine is run at a rated speed of 2400 rpm. This selection gives 540 rpm to the PTO shaft and delivers the fully-advertised horsepower at rated engine speed.
The 540/540 Economy PTO offers all the features of the standard 540-rpm PTO, and the safety interlock is a foolproof measure provided to compensate for operator oversight.
When the tractor is in economy, the engine is limited to 1700 rpm, preventing accidental over-speeding of PTO implements and protecting against binding the PTO shaft.
The safety interlock also prevents accidental shifting of the PTO selector lever at engine speeds above 1700 rpm, which would lead to downtime for fixing implements or drivetrains.
Optional Equipment On: 5E Series equipped with PowrReverser™ Transmission
Creeper gears provide lower ground speeds
For applications requiring ground speeds lower than A range, the 5E Series can be equipped with a field-installed creeper. Creeper ground speeds provide speeds from 0.1 to 0.5 mph.
To operate the creeper, place the range lever in neutral, come to a complete stop, shift the creeper lever to the selected speed, and then select the gear speed.
The creeper option for the 5E is a standard creeper.
Optional Equipment On: 5E Series
Understanding economy power take-off (PTO)
What is economy PTO?
Economy PTO is a feature that allows the operator to run the PTO at 540 rpm but at a lower engine rpm than the standard PTO rated speed. As a result of this engine rpm reduction, benefits realized to the customer include fuel savings (up to 30 percent reduction), less wear and tear on the engine, reduced vibration, and lower sound levels.
Some manufacturers have advertised economy PTO settings that simply reduce the engine rpm only and do not actually change the speed of the PTO shaft. This not only reduces the engine rpm but also reduces the PTO rpm and causes implements to run at slower speeds. Operating a 540 implement at lower than 540 rpm at the PTO reduces its effectiveness.
How does it work?
On John Deere Tractors, the shiftable 540/540E mode operates a little like shifting gears on the transmission. By engaging 540E mode, the operator changes the gear reduction ratio keeping the PTO spinning at 540 rpm but lessening the engine rpm. When the operator shifts the PTO into the standard 540 mode, a different gear reduction ratio is used to operate the PTO at 540 rpm at the standard PTO rated speed of the engine.
To operate in economy mode, the shiftable 540/540E lever must be in 540E. Then the throttle can be increased to the appropriate rpm. When in 540E, the tractor has a throttle limiter that keeps the operator from increasing engine rpm over the 540E setting. The limiter is used to prevent accidental over-speeding of PTO implements and protection against binding the PTO shaft.
When to use 540 economy mode?
540 economy is ideal for many light duty applications including mowing, baling, or spraying. The 540 economy setting cannot be used with full advertised PTO horsepower. If full PTO horsepower is required, operate the tractor in the standard 540 mode. As a general rule of thumb, try operating in economy PTO first if the implement requires less than full PTO rpm to operate it. If the tractor experiences further reduction of engine rpm, the load is too heavy and regular 540 PTO mode should be used to complete the task.
Nebraska Tractor Test has information regarding 540 economy PTO fuel consumption values for tractors where this option is available.
Details on the engine rpm for standard 540 and 540 economy mode can be found in the tractor’s operator’s manual.
Electrohydraulic PTO engagement increases operator comfort
An easy-to-use push/pull knob engages and disengages the PTO independently of the transmission traction clutch. 5E and 5E Specialty Tractors come with an electrohydraulic PTO engagement to reduce operator fatigue. The push/pull knob is conveniently located on the right-hand console.
Adding to operator safety, the tractor does not start with the PTO lever engaged. An alarm sounds if the operator attempts to leave the seat with the PTO engaged. In addition, the PTO shaft is protected by a hinged shield.
Mid-mount selective control valves (SCVs) increase productivity
5E Series Tractors can be equipped with up to four economical and versatile spool-type SCVs.
Based on operator input, the user-friendly and ergonomic joystick is now on 5E and 5E Specialty Tractors.
Standard with factory-installed dual mid hydraulics, the joystick is designed to mold to the hand for increased comfort. A safety lockout feature guarantees the joystick does not respond when the lock is on, allowing the operator to securely move around the work site with confidence the material will stay in the bucket.
The regenerative joystick position provides fast loader bucket dump cycles on the dual mid hydraulic valve only.
Optional Equipment On: 5082E, 5090E, and 5E Specialty Series
Rear-mount selective control valves (SCVs) add versatility
5E and 5E Specialty Series Tractors can be equipped with up to four economical and versatile spool-type selective control valves (SCVs). A maximum of two rear SCVs can be field or factory installed to add versatility to the 5E and 5E Specialty Series Utility Tractors. A single rear SCV comes standard on 5E and 5E Specialty Series Utility Tractors.
All rear SCVs are lever-controlled, and couplers are equipped with plug dust covers to prevent dirt and debris from entering the hydraulic system. This ensures the most reliable performance, allowing operators to get their work done.
Operators can couple and uncouple under pressure with the International Standards Organization (ISO) push-pull couplers, which reduce the muscle required to switch implements. This allows the operator to effortlessly couple and uncouple hydraulic hoses from one implement to another.
Open-center hydraulic system
A tandem-gear pump supplies power to the open-center hydraulic system. This system is essentially two pumps working together as one to provide a high flow rate to the tractor’s hydraulic system. The rear half of the pump delivers hydraulic flow to the steering circuit so steering is effortless, even with a full loader bucket on the front end or a heavy integral implement. The front half of pump supplies hydraulic flow to the selective control valves and 3-point hitch functions.
The system’s high flow rate, combined with the pressure, achieves excellent hydraulic performance and capacity. This provides high loader breakout force so every drive into the feed pile results in a full bucket. Fast cycle times result in time saved when customers are moving material. The system also supplies plenty of flow for running hydraulic motors, which is one more example of the versatility available with John Deere Utility Tractors.

Straddle-mount design provides spacious open-station platform for comfort and convenience
The 5E Series Tractor with a straddle-mount operator station is designed to position the operator farther forward and slightly lower than most other tractors in this class. This design improves the operator’s ride and visibility.
Platform-mounted shift levers and suspended clutch and brake pedals contribute to a clean platform design. Suspended pedals also make it easier for the operator to get on and off the tractor, and make clutch pedal operation easier on the operator when the tractor is used in applications requiring the pedals to be used frequently, such as loader work.
To further enhance access to the operator station, two footsteps (one on the left side and another one on the right side) are provided as standard equipment on all 5E Series Tractors.
Toolbox and operator’s manual holder
All 5E Series Tractors have the optional toolbox with storage locations for tools, parts, and operator’s manuals. The toolbox is conveniently located on the left fender for easy access to tools and spare parts that may be needed in the field. The operator’s manual holder is mounted on the right-hand post of the rollover protective structure (ROPS).
Both are made from a weather-resistant, durable plastic material.
To further enhance access to the operator’s station left-side stairs are available as standard equipment and right-side steps are optional equipment on all 5E Series open-operator station tractors. Enter and exit from either side of the operator’s station.

Two-post foldable Roll-Gard™ ROPS
The standard equipment Roll-Gard rollover protective structure (ROPS) can be folded to permit additional clearance, when needed. With the ROPS in the folded position, straddle-mount tractors with 16.9-30 or smaller tires fit under a standard 2.01-m (6.6-ft) doorway.
Folding the ROPS is simple. Remove two pins and rotate the top of the Roll-Gard ROPS down. Adjustments can be made from the operator’s station.
When low clearance is not required, the ROPS must be in the upright, locked position. The use of seat belts is recommended when operating the tractor with the ROPS in the upright position; it is not recommended when the ROPS is folded down.
Using a canopy is not recommended for applications that require folding the ROPS.
Folding ROPS performance is certified at the date of manufacture, per these standards:
- U.S. OSHA: 29CFR Part 1928, Subpart C
- Canadian CSA: B352.1 (1995)
- Australia: AS 1636.1-1996
- SAE: J2194 SEP97

Climate-controlled cabs increase comfort and performance
Operators will appreciate the comfort and convenience offered through the seat, steering wheel, and lever controls with a rollover protective structure (ROPS) certified, factory installed cab.
The cabs are assembled to the tractor chassis as a complete unit and mounted on composite isolators.
The complete cab assembly includes the floor and steering column. Having this type of fully isolated cab greatly reduces noise levels inside the cab. It also creates a more sealed environment, so the amount of airborne particles entering the cab, such as dust and pollen, are greatly reduced.
The cab is very spacious, allowing ample room for controls and storage. The flat floor adds to the spacious and open feel.
The ceiling control panel is located on the upper-right side which provides the operator with visibility to the loader at a height unmatched by any competitor.
These cabs provide a clean, quiet environment protected from the elements. Powerful air conditioning and heating systems allow the operator to control the cab climate to preference, regardless of the conditions outside. The standard visor blocks the sun on bright days, while a dome light allows the operator to see controls at all times of the day.
The cab’s side windows open forward for excellent ventilation and left side door opens wide for easy entry and egress. A right side door is available as a field-installed option.
For excellent rear visibility, the 30 U.S. gal. fuel tank is located below the left-hand side of the platform.
The rear window opens to 70 degrees, providing further visibility when hooking up implements. An interior rear view mirror provides additional visibility.
The steering wheel not only tilts, but also includes a standard telescoping feature for maximum steering comfort.
The clean, uncluttered interior design with flat platform maximizes operator space. A conveniently located beverage holder is integrated into the design.
Take further pleasure in the ride with a radio or compact disc player available as a field-installed attachment. Cabs are radio ready, including standard speakers and radio wiring harness.
Excellent overall visibility in all applications with a swing out rear window opens to a full 70 degree for easier implement hookup and visibility. A front windshield wiper with washer ensures the operator can see the surroundings of the tractor (rear wiper is available for field installation.)
Excellent night visibility is achieved with work lights, easily adjusted to redirect light without tools.
A convenient three pin power outlet is for a monitor, controllers, and other operating necessities. Four sets of mounting bosses and a removable rear access plug for monitor or controller harnesses also make using a monitor easy.
A rear seven pin electrical outlet socket for implement electrical requirements and a 90-amp alternator will handle increased electrical requirements. To handle increased powertrain and hydraulic requirements in severe conditions, a hydraulic oil cooler is standard.
The battery is located in the front of the tractor for easy access. Fenders are designed to provide plenty of tire clearance, even with the largest wheel and tire combinations.
Additional features are as follows:
- ROPS certified structure for operator protection
- Tempered safety glass in case of breakage
- Left and right outside mirrors available (optional)
- Roof mounted amber turn signal/flashing warning lights for road transport: Two front and two rear
- Two fender mounted taillights for road transport
A deluxe cloth seat with a retractable seat belt is in base equipment:
- An ergonomically sculpted seat cushion, an adjustable scissor-link suspension, and seat armrests are combined to provide excellent operator comfort and support.
- The scissor-link suspension can be adjusted for the operator’s height and weight.
- The operator weight adjustment adjusts to the operator’s weight (115 lb to 275 lb).
- Seat is adjustable fore and aft for the operator’s height, using the lever located under the seat.
- Retractable seat belts prevent the belts from becoming tangled in the seat suspension and controls.
- Optional factory installed air-suspension seat is available.

Save maintenance minutes when servicing 5E Series Tractors
Ease of maintenance ensures the operator will perform daily maintenance, so the 5E Tractor is always ready to work.
The one-piece, tilt-up hood provides easy access to service points under the hood. The front-mounted battery is under the hood and easily accessible.
Remove three simple clips to change the air filter. The drive belt has a self-adjusting tensioner, eliminating a service interval and the need for a wrench. A see-through design of the coolant recovery tank enables checking the coolant level without removing the radiator cap.
Simplify service checks with automotive-type fuses. and an air restriction indicator light that alerts the operator when air cleaner servicing is needed. A 300-hour engine oil and filter change interval saves the owner time and money; the interval extends to 450 hours with Torq-Gard Supreme™ Plus-50™ engine oil.
A transmission fluid check is done by viewing the hydraulic sight glass located under the power take-off (PTO) shield. The sight glass ensures tractor hydraulic performance as there is no opportunity for dirt and debris to enter the system while checking the oil level.
Note the oil level in the photo is overly full; the correct operating level is achieved when oil is at the top arrow in the upper glass (just above the bottom of the upper glass).
The hydraulic filter is changed every 600 hours; increased intervals save the operator maintenance time and money.
Wet-disk brakes provide durability and long life
Operators can expect sure stops when the unexpected happens in the field, on the highway, or at home with hydraulically actuated wet-disk brakes.
Brakes are self-adjusting to eliminate the need for periodic manual adjustments. The brake pedals can be locked together for braking action on both rear wheels when in transport, or they can be unlocked to make tighter turns in the field.
The brakes are oil cooled for maximum performance over the life of the tractor.

9F/3R top shaft synchronized transmission - An easy-to-use transmission that saves time and effort
The transmission is designed to match the excellent power and torque characteristics of the John Deere PowerTech™ engines.
Transmission durability is enhanced with the pressure-lubricated top shaft, allowing an operator to achieve performance from one working season to the next.
Nine forward and three reverse speeds are achieved by using two platform-mounted levers for shift operation. The gear and range levers located at the operator’s right hand side, selects one of forward or reverse speeds and the range lever at the operator’s left hand selects collar shift A, B, or synchronized A and R ranges. Operators can easily switch directions without having to completely stop the tractor with synchronized, in-line, shuttle shift capability between A-R. Forward shifting on the go between speeds and ranges are not synchronized.
A neutral start switch requires that the gear shift lever be in the neutral position to start the engine.
A hand brake or park pawl provides braking during parking of the tractor in selected export markets.
The transmission also has:
- In-line, shuttle shift capability between 2-R (A-Range), 5-R (B-Range) and 8-R (C-Range) for loader work and blade work.
- Constant mesh, helical gears for quieter operation and excellent reliability.
- Fully enclosed, rigid shift linkages for smooth, crisp shifts.
- Neutral start switch requires that gearshift lever must be in neutral position to start engine.
- Pressure-lubricated top shaft for excellent durability.

12F/12R PowrReverser™ transmission is ideal for demanding applications
The John Deere built PowrReverser transmission provides 12 forward and 12 reverse gears for operators requiring additional flexibility for multiple applications. It comes standard with shiftable 540/540 Economy PTO. This transmission is ideal for operators using their tractors to perform in versatile applications.
Hydraulic wet forward and reverse clutches maximize durability and will outlast the life of any dry clutch. When tractors are run by multiple operators with a variety of experience levels, a wet clutch is the best way to maintain transmission integrity and performance while decreasing clutch replacement costs.
Two platform-mounted levers offer easy and comfortable shifting for a pleasant operator experience. The gear-shift lever is easy to reach and the less-used range lever is now shorter.
Unique knobs make it easier to distinguish between the two. The forward lever selects one of four speeds, all synchronized shifts for on-the-go shifting with the use of the clutch. The rear lever selects collar-shift A, B, and C ranges, which are not synchronized.
Maximum productivity is achieved with hydraulic powershift between forward and reverse and is ideal for loader and rear blade applications that require frequent directional switches in tight spaces. Excellent modulation allows the operator to shift the direction lever from neutral to forward or reverse, forward to reverse, reverse to forward, or to neutral from forward or reverse.
Operators can accomplish all these directional changes without sacrificing comfort or having to depress the clutch pedal. The speed of directional changes can be adjusted to the operator’s preference or application demands with the field-installed infinitely variable control kit.
An electrohydraulic fingertip directional lever control allows the operator to effortlessly switch directions with a small finger motion. The control is located on the left side of the instrument console and selects forward, reverse, and neutral positions.
It also allows the operator to steer and shift direction with the left hand, freeing the right hand to operate other tractor controls, such as the loader, rear implements, or hand throttle.
Constant-mesh, helical-cut gears provide quieter operation and excellent reliability while the pressure-lubricated top shaft adds to the transmission durability. Fully enclosed, rigid shift linkages for short throw and crisp shifts enable all operators to clearly know in what range and gear they are operating.
Positive park pawl on the transmission provides positive park and eliminates the need for a hand brake.
This also eliminates clutch service costs that occur when the park brake is accidentally left engaged. A neutral start switch requires the directional lever to be in the neutral position to start the engine.
Optional Equipment On: 5055E, 5065E, 5075E

A wet clutch is submerged in hydraulic oil, absorbing heat, extending clutch life, and reducing the need to budget for clutch repair costs. This is the clutch of choice when multiple operators, with varying degrees of experience, are using the same tractor, especially in high-hour usage.
The PowrReverser transmission features hydraulically actuated clutches that take the place of the dry-type traction clutch. It is not necessary to depress the clutch pedal to move the forward/reverse lever, saving the operator energy to focus on the task at hand and eliminating strains on muscles created by performing a repetitive motion.
The PowrReverser has a built-in engagement override valve for additional safety. This valve requires the clutch pedal to be depressed one time after each engine start before the transmission will begin to operate normally, giving the operator another opportunity to focus entirely on the tractor.

Custom four-wheel drive (4WD) front and rear tire information
4WD front tires must be properly matched to the rear tires (zero percent to five percent overrun) to prevent excessive front-tire wear, unnecessary powertrain loads, and overall poor tractor performance.
In order to achieve maximum drawbar pull, maintain proper steering, and reduce tire wear and fuel consumption when custom-fitting 4WD front and rear tires, the following guidelines must be followed:
The transmission front/rear ratio for standard-width 5 Series Tractors is 1.3495. The inverse, used for 4WD matching calculations, equals 0.741. The 0.741 factor determines the front tire with zero percent overrun. A 0.778 factor, 0.741 x 1.05, determines the front tire with five percent overrun.
- Determine the rear tire desired.
- Obtain the rolling circumference (RC) of that tire from the tire manufacturer’s handbook.
- Calculate the RC of the smallest and largest compatible front tire by using the following formula:
- RC (rear tire) x 0.741 = RC (front tire – smallest)
- RC (rear tire) x 0.778 = RC (front tire – largest)
- Choose a satisfactory matching front tire by scanning the RC column of a tire manufacturer’s handbook. A tire is a satisfactory match if the RC falls between the smallest and largest RCs determined above.
Finding the right tires
What may seem like an easy job, finding the right tire for the application, can have many components. There are many decisions to make when selecting a tire. A few of them include tire size, tread type, load rating needed, radial or bias, and tube or tubeless—all of which can have an impact on the tractor’s performance in the application.
Selecting the right tire begins with understanding basic tire information. Read on to learn more about information to consider when selecting tractor tires.
- Tire
- Wheel/rim
People often use the words tires and wheels interchangeably, but technically that is not correct. A tire is not a wheel.
A wheel, wheel assembly, or rim refers to the metal portion. In the image above, the yellow portion is the wheel or rim. Wheels and rims can be steel or cast. Cast rims are heavier than steel rims and typically can handle a higher load rating.
The tire refers to the rubber part. In the image above, the tire is the black part.
- Rim diameter
- Tire section width.
Tires sizes are typically given in either standard sizes or metric sizes, depending on the manufacturer.
Standard size
U.S. designations (sometimes called standard) measure in inches and typically feature a star load-rating system.
The star designation was related to a standard maximum tire pressure. For example, one star meant a maximum of 18 psi (1.2 bar), regardless of tire size; two stars meant a maximum of 24 psi (1.6 bar); and three stars meant a maximum of 30 psi (2 bar).
Load ratings vary based on tire size. This means a small tire and a large tire could both have a three-star destination, but different load ratings.
Standard size example
18.4R30 ***
18.4 = tire section width (inches) (Number two in the figure)
R = radial construction
30 = rim diameter (inches) (Number one in the figure)
*** = 3 star = symbol
Metric size
The metric designations provide measurements in millimeters and use a load index expressed as a three-digit number. This system has a value-based rating of load-carrying capacity, called the load index (LI).
LI relates to the maximum load-carrying capacity of the tire. The metric tire-rating system allows manufacturers to design tires that better meet specification requirements for diameter-to-width and rolling circumference dimensions, which are critical for mechanical front-wheel drive (MFWD) tires.
Metric size example
480/80R30 145 A8 R1W
480 = tire section width (mm)
80 = aspect ratio (percentage)
R = radial construction
30 = rim diameter (inches)
145 = load index
A8 = speed symbol
R1W = tread designation
In recent years, many agricultural tire manufacturers have moved from the U.S. designation (in.) to a metric designation (mm). The metric designation conveys more information and allows tires to be compared by load index.
Conversion between standard and metric tire sizes
Metric to standard conversion:
Divide the metric number (mm) by 25.4 to get inches.
Example: 480-mm section width/25.4 = 18.9-in. section width.
Standard to metric conversion:
Multiply the standard number (inches) by 25.4 to get millimeters.
Example: (18.4-in section width) x (25.4) = 467-mm section width.
Aspect ratio—This number provides the section height of the tire relative to the tire width. The number is related in a percentage. So a 480/80 has an 80 percent aspect ratio. This means the tire’s sidewall is about 80 percent tall as it is wide.
Aspect ratio = (tire section height/tire section width) x 100.
Speed symbol—This is the maximum speed allowed for the rated load of the tire.

Tread designation—The tread designation describes the tread and indicates the tire use. Utility tractors typically have R1, R1W, R3, or R4 tread designations.
R1 is the most common tread type used in agriculture throughout the United States and Canada. Sometimes called bar tread, R1 provides good traction for dry-land farming.
R1W offers a deeper tread than a R1 tire. At the center, the tread depth is typically 25% percent deeper than a standard R1. The deeper treads of the R1W are popular in wet soils. Many European utility tractors use R1W tires.
R2 has the deepest tread depth. R2 is used for farming extremely wet and difficult conditions. The tread is approximately twice as deep as the R1 tires. R2 tires are rarely used on utility tractors.
R3 offers a less aggressive tread pattern for turf applications. The turf tread pattern reduces potential ground damage, but sacrifices traction. R3 tires are normally wide tires that provide a larger footprint for less compaction. These tires are ideal for turf applications, like mowing parks or harvesting sod. Typically, the tread depth is about half of the tread depth on an R1 tire.
R4, or industrial tread, tires have a tread depth of about 70 percent of an R1 tire. They offer more traction than an R3 tire, but less than an R1 tire.
F2 front-tire treads complement the R1 or R1W rear tires. F2 has a multiple rib steer tire tread and is used in general farming conditions. They are normally found on two-wheel drive (2WD) tractors.
F3 front-tire industrial multiple rib steer tires work well with R4 rear tires. They are normally found on 2WD tractors.
I3 bar-type tread tires look like a small version of the larger drive tires.
Load ratings communicate the maximum load that can be carried by that component. It is important to note there are axle, wheel, and tire load ratings.
The overall load rating of a tractor is determined by the axle, wheel, and tire load ratings. Of those components, the lowest load rating is the restriction. The load rating of the John Deere wheel is at least as high as the load rating of the tire with which it is paired.
In most cases, the tire is the limiting factor regarding load restrictions. This means the tire load index is the most important load rating to know. Refer to the international tire load index numbers chart for information about how the load index relates to pound-carrying capacity.
Agriculture tires are offered in either bias or radial construction. The tire size relates this information. Bias construction by using a “-“. For example a 16.9-30 would be a bias constructed tire. Radial tires have an “R” in the tire size. For example 18.4R30 have radial construction.
Bias tires are preferred for utility tractors that do not perform major tillage operations and do not spend much time on the road and/or are operated for a low amount of hours per year. Bias tires are typically less expensive than radial tires.
Radial tires have a larger footprint than a comparable-size bias tire. This gives radial tires more traction than bias, making them the preferred tire for wet, muddy field conditions or tillage operations. Radial tires have a different type of construction than bias tires. The heavier construction of a radial makes them better suited for operating on pavement.
Tires can be either tube or tubeless. Tubeless tires are tires without internal tubes. Tubeless tires typically last longer and are easier to repair than tube tires. Tubed tires are a little more difficult to repair. A punctured tubed tire requires disassembling the wheel and tire to repair the tube.
Tubed tires are normally desired for tires requiring liquid ballast. Placing the liquid ballast inside the tube saves the tire rim from any contact with the liquid ballast.
Ultimately, the selection of tubed tires vs. tubeless tires depends on the application and operator preference.
