SHREDDING
For shredding, set the cutter lower at rear. Determine
how much lower to set the rear by experimenting in dif-
ferent situations.
CUTTING HEIGHT ADJUSTMENT
1. Level cutter from side to side. Check by measuring
from cutter frame to the ground at each deck rail.
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 approxi-
mately 5.5" below the deck. To check cutting
height, do the following:
a. Place a straight edge along top edge of deck.
b. Select a cutting height; as an example, for an
approximate cutting height of 3", set the center
of the deck 8.5" above the ground.
c. Adjust the front-to-rear attitude from 1/2" to 3/4"
higher than the front or from 9" to 9-1/4" at the
rear.
Before working underneath, disconnect drive-
line, raise cutter, and block cutter securely. Hydrau-
lic system leak down and failure of mechanical or
hydraulic system can cause equipment to drop.
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.
TOP LINK ADJUSTMENT (FIGURE 3)
1. To mount tractor top link, use lowest hole provided
in the tractor’s top link attachment bracket.
2. Select a top link mounting pin that will swing
through the cutter A-frame bars and attach rear
portion of tractor top link in the first hole of cutter
floating link.
3. Raise cutter to transport position and adjust tractor
top link until cutter is level in the raised position.
NOTE: Some tractors are equipped with a short
top link. If you cannot adjust the cutter level using
the middle hole in the cutter floating link, use the
front hole and adjust the cutter level in the trans-
port position.
NOTICE
■ With cutter adjusted to transport position, set
upper stop on tractor lift quadrant to prevent cutter
from contacting the driveline when being raised.
■ Select a top link pin (maximum length 3-5/8")
that will allow floating link to swing freely through
the cutter A-frame bars.
3" - desired cutting height
+ 5.5 - distance blade cutting edge is below deck
= 8.5
