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
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 62
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 accord-
ing to your needs. Firmers should provide just enough
tension to push seeds to the bottom of the trench.

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.

depth wheels/arms and press wheels removed for illustrative
purposes - removal is not necessary for lock/unlock)
