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 disc blades may be sharp. Use caution when making
adjustments in this area. To adjust the Keeton
®
Seed Firmer,
lower the planter until the discs 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”.
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.

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.

discs, side depth wheels/arms and press wheels
