Unit-Mount Cleaner Adjustments
Refer to Figure 89 and Figure 90
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 planter raised. Install
lift-assist cylinder locks. Also check bolt
tightness prior
to each planting session, to avoid down-stop slippage.
To adjust the row cleaner:
1.
Determine the height adjustment required. Measure
from the lowest tine to the ground. Determine the
desired new measurement.
2.
Support most or all of the weight of the arm to
prevent injury and ease the adjustment. Loosen
bolts
on UMC-RC. Remove bent pin
on UMRC.
3.
Support arm at desired height.
4.
UMRC: Slide adjustment tube
until cross-tube
contacts arm at target height. Insert bent pin
in
whichever hole pair is most in alignment.
5.
UMC-RC: Slide the down-stop
on the arm
:
- back toward the pivot for shallower cleaning, or
- forward toward the tines for deeper cleaning.
Tighten the bolts
. Each possible hole pairing
adjusts the tine height by about
3
/
4
inch (19 mm).
6.
Check the new height measurement.
Refer to Row Cleaner manual 204-085M-A for further
information on use, adjustment and maintenance of row
cleaners.
