Seed Firmer Adjustments
20 and 25 Series row units accept one of two optional
seed firmers.
Sharp Object 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 poly-
mer 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 53
The Firmer is provided with a preset tension which is rec-
ommended 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.
FigureSpacer 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 problems
associated with this, you can lock-up the firmers.
Refer to Figure 54
To lock up Seed-Lock wheels:
1. Raise drill.
2. Rotate Seed-Lok™ lock-up handle 90 degrees
down on top of row unit body.
3. Push up on Seed-Lok™ wheel until wheel arm
latches up.
