Seed Firmer Adjustments
Depending on row option originally specified, 00 Series

. An optional
Keeton

seed firmer may be ordered separately.
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:
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 37
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.

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.

clarity - this task can be performed with disks mounted)
To lock up Seed-Lok
®
wheels:
1. Pull catch wire aside .
2. Pull firming-wheel arm up and release wire to
