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.
Excess wear is cause for replacement.
Note: When installing a seed wheel that requires Flow
Gate, also remove the meter slide. If replacing a
rice wheel with another seed wheel, re-install the
meter slide. See page 140.

Unit-Mount Cleaner Adjustments
Refer to Figure 116 and Figure 117
Optional Martin row cleaners are unit-mounted, using:
UMRC: Unit-Mount Row Cleaner (stand-alone), or
UMC-RC: Unit-Mount Coulter RC (on coulter bracket,
with or without a coulter disk present).
There are two adjustments:
1. Wheel placement (forward or aft mounting hole, for
more or less aggressive cleaning), and
2. Wheel height, adjusted by a stop. Cleaner arms
float. The stop only sets the lowest position.
In UMRC mount, a pinned cross-tube on the mount
adjusts the depth. In UMC-RC (coulter) mount, a sliding
down-stop block
adjusts how close to the ground the
row cleaners operate.
The row cleaner needs to be adjusted for your
conditions, crop changes, and as coulters and openers
wear. Ideally, cleaners contact only the trash, and do not
disturb the soil. If allowed to “dig”, row cleaners can
reduce seed coverage.
Suggested initial depth is tine tips at ground level.
Make the adjustment with the drill raised. Install lift-assist
cylinder locks. Also check bolt
tightness prior to each
planting session, to avoid down-stop slippage.
