inch, shorten top link or limit upper travel of lower
hitch arms. Refer to tractor operator's manual for
instructions.
CUTTING HEIGHT ADJUSTMENT
Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
■ Avoid low cutting heights. Striking the ground
with blades produces one of the most damaging
shock loads a cutter can encounter. Allowing
blades to contact ground repeatedly will cause
damage to cutter and drive.
1. Level cutter from side to side. Check by measuring
from cutter frame to the ground at each side skid.
2. Adjust, using tractor 3-point arm leveling device.
NOTE: Keep the front of cutter slightly lower than
rear for best mowing.
3. Control cutting height with tractor 3-point arms,
rear tailwheel adjustment.
4. To raise rear of cutter, move tailwheel arm down.
5. To raise front of cutter, raise tractor 3-point arms.
The cutting height is the distance between the blade
and the ground. The blades are approximately 1.25"
above the side skid. To check cutting height, do the fol-
lowing:
a) Select a cutting height; as an example, for an
approximate cutting height of 3", set the side skid
above the ground:
b) Adjust the front-to-rear attitude from 1/2" to 3/4"
higher than the front.
6. Adjust top link to provide 1.2" of clearance between
break link and rear lift arms. See Figure 8. The
clearance will allow cutter to float over uneven
terrain.
SHREDDING MATERIAL HEIGHT
ADJUSTMENT
For shredding, set the cutter lower at rear. Determine
how much lower to set the rear by experimenting in dif-
ferent situations.
Figure 8. Cutting Height Adjustment
CHECK CHAIN ADJUSTMENT (OPTIONAL)
1. Refer to INSTALL OPTIONAL CHECK CHAINS,
page 32 for check chain installation.
2. After making cutting height adjustment, adjust both
chains (3) in check chain bracket (2) so you have
the same number of links on each side. This will
keep cutting level.
