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.
Refer to Figure 100
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.
Measure the distance from the ground to the head of the
tension screw. This distance should be 4 to 4
1 ⁄
2
inches
(10.2 to 11.4cm). If not, loosen the bolts in the mounting
bracket and select different holes until the proper
measurement is attained.
