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 3-8. 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.

arm. See Figure 3-10.

Closing Wheel Offset
If the closing wheels are not offset, mount wheels in the
front holes of press-wheel arm.
Closing Disk Option
For proper seed-to-soil contact, the closing disks must
have enough down pressure to close the seed trench with-
out unnecessary soil compaction.
To adjust down pressure on closing disks, ratchet spring
cam to next cam height by turning head of support bolt (1)
clockwise. Refer to Figure 3-11.
