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 pre-
vent 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.
Unit-Mounted Coulter Adjustments
Note: Applies only to 10HDP and 25P Series.
Note: Unit-Mount Coulters are not factory-installed.
Check alignment and depth prior to first use.
Coulter Depth Adjustment
The ideal operating depth for unit-mounted coulters is
1
⁄
4
in above opener depth. Although they may have origi-
nally been set to this depth, coulter (and opener) blades
wear with time, and may need adjusting.
Adjusting the coulter depth is accomplished by re-mount-
ing the coulter blade in one of the six mounting holes
arranged in a staggered pattern in the coulter bracket.
Refer to Figure 84 and Figure 85
Raise YP30 planter 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 cur-
rent or new position causes it to contact the ground dur-
ing the adjustment. Be careful around the front end of
row units. Coulter blades may be sharp.
