- 670 Disk uses straight cast standards to help deal with in-field obstacles.
- Straight cast standard.
- 670 Disks use the same straight cast standards as John Deere’s rugged tandem disks.
- 670 Disks use massive straight standards. Straight standards direct thrust forces up, to eliminate twisting of the gang tube when an obstacle is encountered.
- Choice of disk blades enables operators to match the disk to the job
- Blade spacingBlade spacingThe 225 Disk is available in 229-mm (9-in.) blade spacing, and the 425 Disk is available with 229-mm (9-in.) or 279-mm (11-in.) blade spacing. Blade spacing recommendations for best performance are as follows:
229-mm (9-in.) spacing 279-mm (11-in.) spacing Seedbed preparation All primary tillage Chemical incorporation Heavy residue conditions Light primary tillage Average residue levels
Blade shapes (cone, spherical, solid, cutout) Cone-type or spherical blades are available in a variety of sizes with a solid or cutout design.
- 559-mm (22-in.) or 610-mm (24-in.) diameter solid or cutout design on 225 Disk
- 610-mm (24-in.) or 661-mm (26-in.) diameter solid or cutout design on 425 Disk
Blade tapers and furrow filler Right rear gang is tapered and includes two smaller disks to feather the soil.
Blade size (diameter) Blade taper size (diameter) 559 mm (22 in.) One 508 mm (20 in.) and one 457 mm (18 in.) 610 mm (24 in.) One 559 mm (22 in.) and one 508 mm (20 in.) 661 mm (26 in.) One 610 mm (24 in.) and one 559 mm (22 in.)
Reduced furrow filler blade
A 356-mm (14-in.) diameter furrow filler (arrow) is available to further smooth and level the soil.A scraper is included with the furrow filler.
Combination or rigid scrapers available for versatility in a variety of soil conditions. Combination scrapers shown. Combination or rigid scrapers are available on the 670 Offset Disk.Combination scrapers are desirable in sticky soil conditions:
- Lock rigid to prevent wear in abrasive and dry soils
- Self-adjusting for sticky soils
- Positioned for excellent residue handling
Rigid scrapers complement the strength of the 670 Disk and are adjustable for long-wear life in lighter, non-sticky soils.
Conveniently located single-point depth control provides infinite range of depths. Single-point depth control. The single-point depth control is base equipment.
- Conveniently located at the front of the disk
- Provides an infinite range of depths
- Eliminates lost or broken mechanical depth stops
Hitch can be set to meet disking needs
Hitch bar (1), adjustment holes (2), clevis (3)
The hitch can be set to work directly behind the tractor or offset to the right or left, which is ideal for orchards or vineyards.
Moving the tongue on the hitch bar (1) provides a course adjustment.
Changing the angle of the hitch tongue, through a series of holes (2), fine-tunes adjustments.
The clevis (3) can be assembled so a disk harrow can be used with tractors having either a straight or open-type drawbar.
A safety chain and hose support are included in base equipment.
One-piece welded mainframe provides reliable strength
425 Offset Disk
The mainframe on 225 and 425 Offset Disks is made of one-piece, heavy, structural steel tubing to resist torsional forces on the frame:
- 102 mm x 102 mm x 5 mm (4 in. x 4 in. x 3/16 in.) on the 225 Offset Disk
- 76 mm x 127 mm x 10 mm (3 in. x 5 in. x 3/8 in.) on the 425 Offset Disk
Self-aligning Dura-Flex™ (3+1) gang bearings protect seals from wire and twine
Dura-Flex bearings (3 + 1) are standard on 670 Offset Disks:
- Installed in a wide flange to protect seals from wire and twine
- Dynamically self-aligns to minimize preload and thrust loads
- Triple-lip seals (3) to keep grease in and dirt out
- Housing lip (1) inside flange to allow the bearing to dynamically self-align in housing
- Two-year warranty
