Note: With the seed meter wheel removed, you may want
to check the meter for internal damage or trash.
Note: Some wear on top edge of slide is normal. Ex-
cess wear is cause for replacement.

tem before installing new meters or wheels. “Clean-
ing Out Air System” on page 97.

Gate, also remove the meter slide. If replacing a
rice wheel with another seed wheel, re-install the
meter slide. See page 100.

Seed Firmer Adjustments
Note: Applies to all row units.
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).
Sharp Object Hazard:
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 111
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 furrow.
