Adjustments
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
in (19mm).
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.
Coulter Adjustments
Coulters are not factory-installed. Check alignment
and depth prior to first use.
Coulter Depth Adjustment
The ideal operating depth for coulters is
1
4
in (6mm)
above opener depth. Although they may have originally
been set to this depth, coulter (and opener) blades wear
with time, and may need adjusting.
Adjusting the coulter depth is accomplished by
re-mounting the coulter blade in one of the six mounting
holes arranged in a staggered pattern in the coulter
bracket.
Refer to Figure 116 and Figure 117
Raise drill and install cylinder locks before working on
coulters. Row unit may be fully lowered or locked up. Do
not attempt to move blade when the current or new
position causes it to contact the ground during the
adjustment. Be careful around the front end of row units.
Row cleaner tines and coulter blades may be sharp.
