• Stabilizes rear of the plow in soft soils
• Adjustable through a full range of plowing depths
• Designed for easy turnbuckle adjustment
• Equipped with 6.70-15 tire to eliminate bulldozing in soft soils

Adjustable width of cut improves residue-handling ability

Adjustable width of cut

The width of cut on all 975 Moldboard Plows can be set at 406 mm or 457 mm (16 in. or 18 in.) by moving the standards to different bolt holes in order to:

• Match the tractor horsepower to the soil conditions
• Improve the residue-handling ability
• Improve productivity
• Maximize fuel efficiency

The underframe clearance is 813 mm (32 in.) to allow excellent material flow through the plow.

Attaches to 3-point hitch

The 22B In-Line Ripper attaches to the tractor’s 3-point hitch:

• 25-mm x 686-mm (1-in. x 27-in.) standard model is compatible with Category 1, 3-point hitch tractors.
• 32 mm x 838 mm (1.25 in. x 33-in.) standard model is compatible with Category 2 or 2/3N tractors with or without Quik-Coupler
  • 16.9-30 or larger rear tractor tires are recommended

Coulter blades slice through surface residue

Rippled coulter blades cut through surface residue such as cornstalks, wheat stubble, or other heavy crops to help reduce plugging.

The ripple on the blade bites into the soil to promote turning the blade in wet and/or firm soil, as well as lighter, drier soils.

Cushion or shear-bolt designs are available.

Cushion design

Cushion-designed coulter blades

• Automatically returns the coulter to the operating position once the obstruction is passed.
  • Saves time by eliminating the need to stop and replace shear bolts.
• Unique rosette bracket used to adjust the coulter depth. Simply loosen one bolt and swing the coulter up or down to the desired height.
  • Standard does not move, so maximum trash clearance is retained.
• Protector bolt (arrow) will yield if the obstruction height exceeds the deflection range of the coulter, thus preventing serious damage to the coulter.
• 457-mm or 508-mm (18-in. or 20-in.) rippled blades are available for good cutting action. The maximum working depth is as follows*:
  • For the 457-mm (18-in.) coulter blade, the working depth is 483 mm (19 in.)
  • For the 508-mm (20-in.) coulter blade, the working depth is 457 mm (18 in.)

*NOTE: When ripping in fields with obstructions, it is necessary to restrict the working depth in order to give the coulter space to travel over obstructions. Without coulters, the maximum working depth is 584 mm (23 in.) for shear-bolt standard and 559 mm (22 in.) for safety-trip and spring-reset standards.

Shear-bolt design

Shear-bolt design coulter blades

• Provides economical alternative for protecting coulters in fields with few obstructions.
• 457-mm, 508-mm, or 559-mm (18-in., 20-in., or 22-in.) rippled coulter blades are available for good cutting action. The maximum working depth is as follows:
  • For 457-mm (18-in.) coulter blades, the working depth is 483 mm (19 in.)
  • For 508-mm (20-in.) coulter blades, the working depth is 457 mm (18 in.)
  • For 559-mm (22-in.) coulter blades, the working depth is 432 mm (17 in.)

Easily maneuver tight turns with integral in-furrow hitch

Integral in-furrow hitch

Compatible with tractors equipped with Quik-Coupler, the integral hitch offers unexcelled maneuverability in turns and when parking in tight areas:

• Tractor rockshaft lever controls the raising and lowering of the plow
  • Maximum plowing depth is 356 mm (14 in.)

Economical single parabolic standard ripper promotes root growth

A single parabolic standard ripper provides an economical means of shattering hardpan soil by exploding the soil upward to promote root growth:

• Curved standard is less likely to slice through marginally moist soils than a straight standard
• Mole ball can be attached to the standard to help drain wet soils by leaving a small tunnel under the soil
• V-knife can be attached to the standard to effectively cut the root systems
• Improves water percolation into the subsoil zone

Two sizes of standards are available:

• 25 mm x 686 mm (1 in. x 27 in.)
  • Maximum working depth of 406 mm (16 in.)
• 32 mm x 838 mm (1.25 in. x 33 in.)
  • Maximum working depth of 559 mm (22 in.)

Both standards are protected for up to 6364 kg (14,000 lb) of operating force by a 16-mm (5/8-in.) shear bolt.

Excellent residue-handling capability in primary tillage at all residue levels

915 V-Ripper

The 915 V-Ripper has excellent residue-handling capability in primary tillage at all residue levels. At higher levels, coulters may be required to minimize plugging.

Typical percentage of residue cover remaining from the 915 are listed as follows.

NOTE: The percentage do not take into account variables such as the condition of the residue, speed, and soil type.

*Non-fragile residue includes crops like corn, sorghum, wheat (more than 45 bu).

**Fragile residue includes crops like soybeans, edible beans, peas, wheat, (under 45 bu), sunflower, peanuts, cotton.

Moldboard frame pivots with the bottoms

975 mainframe

All 975 Moldboard Plows use only one set of bottoms.

The moldboards are reversed laterally by a hydraulic cylinder that is standard equipment. There are several advantages of this design over traditional two-way rollover plows with two sets of bottoms:

• Requires less 3-point hitch capacity
• Requires less ballasting of the tractor front end
• Eliminates initial cost and service requirements for one complete set of standards and bottoms

Reversing pin

The reversing pin is positioned at a 13.5-degree angle, instead of being straight up, for even plowing in both directions. The reversing pin does not require adjustments by the operator.
