Offset
The 1 X 12 closing wheels can be offset to help prevent
trash from plugging the wheels. If the closing wheels are
not offset, the wheels should be located in the front holes
of the press-wheel arm.
To offset the wheels:
1. Raise planter slightly to remove weight on the closing
wheels.
2. Remove the bolt holding the wheel shown in Figure 3-
13.
3. Move the wheel to the rear hole and re-attach with
bolt. Tighten the bolt to the correct torque value listed
in on Torque Value Chart, “Appendix” on page
52.

Seed-Lok
The optional Seed-Lok firming wheels are spring loaded
and do not require adjusting. In some wet and sticky con-
ditions the wheels can accumulate soil and may need to
be removed until conditions improve.
The firming wheels attach to the shank with a 1/2-inch cle-
vis pin as shown in Figure 3-16. To remove the wheels, re-
move the clevis pin and pull down on the mount.
Reattach in the reverse order.
