IMPORTANT: If attaching with quick hitch, the distance
between the tractor PTO and gearbox input shaft will
increase. Follow the steps as you would for a 3-point
hitch to ensure proper engagement.
DRIVELINE INTERFERENCE CHECK
1.
Check for proper clearance between driveline and
mower deck. If using a quick hitch, check
clearances between quick hitch and driveline.
2.
Slowly lift mower and observe driveline. If
clearance between driveline and mower 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.
ADJUSTING CUTTING HEIGHT
Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
NOTICE:
Avoid low cutting heights. Striking the
ground with blades produces one of the most dam-
aging shock loads a mower can encounter. Allow-
ing blades to contact ground repeatedly will cause
damage to mower and drive.
IMPORTANT: The front of the deck is designed to
be 1/8" lower than the rear of the deck when all
caster wheels have the same number of wheel
spacers. This helps the mower cut grass more effi-
ciently.
1.
Level mower from side to side. Check by
measuring distance from mower side frame to the
ground at each deck rail.
2.
Verify that the same amount of spacers are under
all caster arms.
3.
Control cutting height by adjusting front and rear
caster wheels spacer count. See Table 1.
4.
To raise front or rear of mower, move caster
adjustment spacers from above caster arms to
under caster arms.
5.
To lower front or rear of mower, move caster
adjustment spacers from under caster arms to
above caster arms.
TRACTOR TOP LINK ADJUSTMENT
When the cutting height is set, adjust tractor top link
until mower top hitch links (70) point downward
between 30 and 45 degrees below horizontal. Secure
tractor top link jam nut. The front tires of the mower will
lift off the ground before the rear tires when raised.
This will allow the mower to follow the ground contours
when mowing. (See Figure 13)

FRONT ROLLER (OPTIONAL)
The caster wheels effectively reduce scalping in most
cases. However, you may encounter areas where the
caster wheels and/or frame sides drop into depressions
and allow center of the mower to contact ground and
scalp. An optional front roller may be installed to mini-
mize scalping. See page 44.
