Bolt-on, knock-on, and s-tine sweep options are available to customize the 2230 Field Cultivators to perform well in a variety of field conditions.
*NOTE: S-tine sweeps not available for all 2230 configurations.
John Deere’s high-productivity sweep options are recommended for the high-working-speed market and perform best at speeds of 11-16 km/h (7-10 mph). With a low profile and curved wing shape, the high-productivity sweeps provide low draft and consistent penetration while easily getting through tough and heavy residue. Compared to Tru-Width sweeps, high-productivity sweeps are designed to exert less draft and retain their shape for longer wear life so producers can stay productive in the field longer.
The high-productivity sweeps are available bolt-on and the knock-on Perma-Loc versions. They fit all 47-degree standards with 44-mm (1.75-in.) hole spacing and 11 mm (0.4375 in.) that currently take Tru-Width sweeps, both John Deere and other makes.
Sweep sizes
229-mm (9-in.) sweeps and 178-mm (7-in.) sweeps can both be utilized on a machine with shanks on 152-mm (6-in.) spacing. The decision between the two is dependent on soil type, operating speed, and the agronomic goal of the tillage pass.
- 229-mm (9-in.) sweeps – When weed management or weed removal is an important part of the tillage pass, a 229-mm (9-in.) sweep provides more of a cutting edge and can catch weeds that may bend around the wings of the 178-mm (7-in.) sweep.
- 178-mm (7-in.) sweeps – These sweeps provide enough wing width to maintain full-width tillage, but with less draft load than a 229-mm (9-in.) sweep. Less draft results in the shank maintaining a more consistent depth, especially at higher speeds, and less of a horsepower draw on the tractor. This will be most evident in harder, heavier soil types.
- 114-mm (4.5-in.) sweeps – These sweeps are only available on S-tine configurations.
Bolt-on sweeps
The Tru-Width design offers the following benefits:
- Maintains full cutting width and point through the life of the sweep
- Gives greater wear life and improved performance over regular sweeps
- Provides superior scouring and penetration
- Works soil well for level seedbed and good seed-to-soil contact
- Gives excellent chemical incorporation
- Wears evenly and pulls easily
- Replacement without charge if breakage occurs before appreciable wear
Knock-on sweeps
Perma-Loc sweep
High-productivity Perma-Loc sweep
Perma-Loc utilizes a self-tightening ratcheting system for easy installation. Indentations formed in the sweep stem provide the spring clip with a locking surface. The adapter edge, sweep, and spring all act together to tightly lock the sweep to the shank. The operator simply pushes the sweep on by hand to the first notch (audible click). As the resistance is increased (ground engagement), the sweep progressively wedges tighter. The mounting design minimizes lost sweeps and wear on adapter.
Utilizing the removal tool to depress the spring through the stem access opening and a tap with a hammer easily releases the sweep from the adapter and spring.
Perma-Loc sweeps have the advantage of using a Tru-Width design for penetration, residue flow, and long life. The proven 47-degree sweep angle minimizes soil slabbing yet promotes soil movement. The narrow stem enhances excellent soil and residue flow. Stem geometry ensures soil flow over the spring access opening, effectively separating and lifting flow to a point higher on the shank. The force of soil flow is reduced on the shank, improving shank life.
Tru-Width sweeps with the Perma-Loc adapter can seamlessly move the high-productivity sweeps. The high-productivity sweeps use the current Perma-Loc adapter for 47-degree curved standard, N237614.
