Seed Firmer Adjustments

Series 25 row units include a standard seed flap, and
accept one of two optional seed firmers (which may be
included in your selected opener bundle).

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 planter 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 100
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.

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 101 (which depicts a row unit with discs, side
depth wheels/arms and press wheels removed for illustrative
purposes - removal is not necessary for lock/unlock)
