1 x 12 Closing Wheel Adjustments
The 1 X 12 closing wheel option can be adjusted for down
force, alignment and offset.
Down Force
Adjust the closing-wheel so it has enough down force to
close the seed trench without unnecessary compaction.
Start with the T-handle in the first notch. See Figure 3-11. If
the seed trench does not close, move the handle to the
next notch back and try again. Keep moving the handle
back just until the seed trench closes.

wheels are not centered over the seed trench, adjust the
closing wheels as follows.

closing wheels.
2. Loosen the two 1/2-inch bolts shown in Figure 3-12.
3. Turn the press wheel adjuster left or right to center the
wheels over the seed trench.
4. Tighten the 1/2-inch bolts as listed on the Torque Val-
ue Chart,“Appendix” on page
