Seed Firmer Adjustments
00 Series row units include a seed flap, and an optional
Seed-Lok seed firmer.
The seed flap requires no adjustment, but may need to
be replaced if worn, and may need to be shortened if an
optional seed firmer is added after initial delivery.
!
CAUTION
Row unit disk blades may be sharp. Use caution when mak-
ing adjustments in this area.
Seed-Lok™ Seed Firmer Lock-Up
Optional Seed-Lok firming wheels provide additional
seed-to-soil contact. The wheels are spring loaded and
do not require adjusting. In some wet and sticky condi-
tions the wheels may accumulate soil. To avoid prob-
lems associated with this, you can lock-up the firmers.
Refer to Figure 105 (shown with an opener disk removed for
clarity - this task can be performed with disks mounted)
To lock up Seed-Lock wheels:
1. Pull catch wire aside .
2. Pull firming-wheel arm up and release wire to
catch arm.
