Sprocket Indexing (Stagger)
If you are planting:
• twin-row crops,
• with seed disks having 24 cells or less,
• at seed interval spacings above 6
1 ⁄
2
inches (16.5cm),
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 Rate Manual for details.
Seed Firmer Adjustments
25AP 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.
Keeton Seed Firmer Adjustment
The optional Keeton Seed Firmer is an engineered poly-
mer 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 57
The Firmer is provided with a preset tension which is rec-
ommended 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.
