4. Move wheel arm in so side gauge wheel contacts
opener disk. Tighten hex-head bolt to clamp arm
around bushing and shank.
5. Check the wheel-to-disk contact. Lift wheel and arm.
When let go, the wheel should fall freely.
• If wheel does not contact disk from 4 to 8 o’clock,
move hex adjuster until wheel is angled for proper
contact with disk.
• If wheel does not fall freely, loosen hex-head bolt
and slide wheel arm out just until wheel and arm move
freely. Retighten hex-head bolt.
6. Keep turning hex adjuster and moving wheel arm until
the wheel is adjusted properly. When satisfied, tighten
pivot bolt to 110 foot-pounds.

Starting Point
1 x 12 Closing Wheel Option
The closing wheels can be adjusted for down pressure,
alignment and offset.
Down Pressure. Adjust the closing wheel so it has enough
down force to close the seed trench without unnecessary
compaction.
Start with T-handle in first notch. See Figure 3-13. If the
seed trench does not close, move handle to next notch
and try again. Keep moving handle back just until the seed
trench closes.

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

wheels.
7. Loosen two 1/2-inch mounting bolts (1) shown in Fig-
ure 3-14.
8. Turn adjuster cam (2) left or right to center wheels over
the seed trench.
