included in your selected opener bundle).

adjustments in this area. To adjust the Keeton

Seed Firmer,
lower the implement name until the discs of the row units are

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 107
The Firmer is provided with a preset tension which is
recommended for using the first year. Tension screws
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.
