Seed Firmer Adjustments
00HD Series row units include a seed flap, and accept
one of two optional seed firmers.
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.
Sharp Objects Hazard:
Row unit disk blades may be sharp. Use caution when making
adjustments in this area. To adjust the Keeton Seed Firmer,
lower the drill until the disks of the row units are resting on the
ground.
Keeton Seed Firmer Adjustment
The optional Keeton Seed Firmer is an engineered
polymer shape that slides down the seed trench. It traps
seeds as they exit the seed tube and firms them into the
bottom of the “V”.
Refer to Figure 59
The Firmer is provided with a preset tension which is
recommended for using the first year. The tension screw
can be tightened in subsequent years according to
your needs. Firmers should provide just enough tension
to push seeds to the bottom of the trench.
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
conditions the wheels may accumulate soil. To avoid
problems associated with this, you can lock-up the
firmers.
Refer to Figure 60
To lock up Seed-Lock wheels:
1. Pull up on Seed-Lok arm .
2. Raise lever .
