Row Cleaner Adjustments
Refer to Figure 48
Optional rigid tine cleaners are unit-mounted, using
UMC-RC: Unit-Mount Coulter RC (on coulter bracket,
with or without a coulter disk present).
Sharp Object Hazard:
Row cleaner tines, casting edges and coulter blades are sharp.
Wear hand protection when working in this area.
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. The
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
.
3.
Support arm at desired height.
4.
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
.
5.
Check the new height measurement.
Refer to Row Cleaner manual 204-085M-A for further
information on use, adjustment and maintenance of row
cleaners.
