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 Object Hazard:
Use caution when making adjustments in this area. Row unit
disk blades may be sharp. To adjust the Keeton
®
seed firmer,
lower the drill until the disks of the row units are resting on the
ground.

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 furrow “V”.
Refer to Figure 72
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.
