Sprocket Indexing (Stagger)
If you are planting:
• twin-row crops,
• at seed interval spacings above 6
1 ⁄
2
inches (16.5 cm),
you can synchronize each pair of adjacent meters in a
twin row so that you achieve the maximum seed-to-seed
spacing between the units of the pair.
Refer to the Seed and Fertilizer Rate manual (401-923B)
for instructions and charts.
Seed Firmer Adjustments
25 Series row units include a standard seed flap, and
accept one of two optional seed firmers (which may be
included in your selected opener bundle).
Row unit disk blades may be sharp. Use caution when making
adjustments in this area. To adjust the Keeton
®
Seed Firmer,
lower the planter 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 “V”.
Refer to Figure 102
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.
