Seed firmers (13) - The seed firmer minimizes seed
bounce and improves soil contact. It may also deliver
fertilizer. see “ Coulter Row Alignment ” on page 52.
The seed flap is standard. The Keeton
®
seed firmer
(shown) is optional.
Disk scraper/separator (14) - The scraper/separator
can also place liquid fertilizer under the seed.
Side depth wheel contact adjuster (15) - see “
Side
Depth Wheel Adjustments ” on page 48.
Press wheel centering adjuster (16) - see “ Press
Wheel Centering ” on page 51.

Row Unit Down Pressure
The ideal amount of down force causes the side
depth wheels to compress any loose surface soil, but
not press a trench into the subsoil.
To check down force, operate the planter for a short
distance on typical ground, with or without seeding,
and stop. Leave the planter lowered with row units in
the ground.
At several row units, inspect the furrow created by
the opener disks, but before the furrow closing by the
press wheels (A).
Be sure to inspect rows in and out of tire
tracks.
• (1)If the side depth wheels are leaving no
tracks, or light tracks, increase down force.
• (2)If the side depth wheels are compressing
trash and loose soil, and leaving clear tracks at
the top of the subsoil, down force is correct and
needs no adjustment.
• (3)If the side depth wheels are creating a trench
into the subsoil, down force is too high and needs to be
reduced.
Down-Pressure Adjustment
Population Risk
Do not set all rows any higher than notch 4.
Using settings above this on all rows will create
uneven depth control and improper function.
