7.
Repeat step 6 for the other half of the drive.
8.
File and clean cut ends of both drive halves.
Do not use tractor if proper driveline engagement cannot be obtained through
these methods.
Connect driveline to tractor PTO shaft, making sure the spring-activated lock-
ing 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 25.4 mm (1 inch), shorten top link or limit upper
travel of lower hitch arms. Refer to tractor operator's manual for
instructions.
CUTTING HEIGHT ADJUSTMENT
CHECK CHAIN ADJUSTMENT
1.
Refer to Install Optional Check Chains, page 28 for check chain
installation.
MAN1254 (3/16/2018)

Keep all persons away from operator control area while performing
adjustments, service, or maintenance.
■
Avoid low cutting heights. Striking the ground with blades pro-
duces 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:
ing.
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 215.9 mm (8.5") 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 76.2 mm (3"), set the center of the deck 292.1 mm (11.5") above the
ground:
+ 215.9 mm
= 292.1 mm
c)
Adjust the front-to-rear attitude from 12.7 to 19.05 mm (1/2 to 3/4") higher
than the front.
6.
Adjust top link (BB60XE, BB72XE, BB84XE) to provide 50.8 mm (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 different situations

. Cutting Height Adjustment
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.
Keep the front of cutter slightly lower than rear for best mow-
