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).

adjustments in this area. To adjust the Keeton

lower the planter until the disks of the row units are resting on

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 115
The firmer has 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 furrow.
