8. File and clean cut ends of both drive halves.
Do not use tractor if proper driveline engagement can -
not be obtained through these methods.
Connect driveline to tractor PTO shaft, making sure the
spring-activated locking collar slides freely and locks
driveline to PTO shaft.
NOTICE
■
If attaching with quick hitch, the distance
between the tractor PTO and gearbox input shaft
will increase. Please follow the steps as you would
for a 3-point hitch to insure proper engagement.
DRIVELINE INTERFERENCE CHECK
1. Check for clearance between driveline and cutter
deck.
2. Slowly lift cutter and observe driveline. If clearance
between driveline and cutter deck is less than 1
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 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, or optional check chains.
4. To raise rear of cutter, move tailwheel arm down.
5. To raise front of cutter, raise tractor 3-point arms or
shorten optional check chains.
The cutting height is the distance between the blade
and the ground. The blades are approximately 8.5"
below the deck. To check cutting height, do the follow
-
ing:
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 11.5" above the ground:
c) Adjust the front-to-rear attitude from 1/2" to 3/4"
higher than the front.
6. Adjust top link (BB60X, BB72X, BB84X) to provide
2" of clearance between break link (2) and rear lift
links. See Figure 10. The clearance will allow cutter
to float over uneven terrain.
SHREDDING MATERIAL
For shredding, set the cutter lower at rear. Determine
how much lower to set the rear by experimenting in dif
-
ferent situations.
