Leveling the Mower
7.
Set lower hitches and upper floating hitch, as shown
below in Figure 3-1.
8.
Start tractor and raise mower, watching that tractor
draw bar (if not removed) does not interfere with
mower.
9.
Slowly lower the mower until gauge wheels touch the
ground and the lower mower 3-point hitch bars are
parallel to the ground in floating position. Set tractor
3-point stop.
10. Set park brake and turn off tractor. Remove key from
ignition.
11. Rotate blades parallel to direction of travel.
12. Measure the clearance from the cutting edge to the
ground at front and rear of the blade. This
measurement should be equal or have the blade at
the front of the mower not more than 1/2" lower than
the blade at the rear of the mower.

!
CAUTION
Engage parking brake, shut off tractor, remove key and
disengage PTO before making any height adjustments!
Cutting Height Adjustment
1.
Using the tractor, raise the mower off the ground and
support under it with secure blocking so not to let the
mower drift down during maintenance.
2.
Holding wheel and yoke assembly up, remove quick-
lock pin from top of gauge wheel spindle. Position full
length spacers and half spacer as required. All
spacers on top of spindle tube allows for
approximately
3/4" cutting height. Adjustments range from 3/4" to a
maximum of 5-1/4" in 1/2" increments. Refer to
“Leveling the Mower” at the top this page.
NOTE: Tractor and mower should be on level
ground.

3-Point Hitch Adjustments
The 3-point hitch system on this mower has been
designed for front to back flotation when mowing on
uneven terrain. Adjust the tractor’s top link to place the
upper hitch pin vertically above the lower hitch pins as
shown below.
Belt Tension
Refer to Figure 3-2:
!
CAUTION
Belt drive system under spring tension; use care to avoid bodily
harm!
1.
To check tension apply force at arrow “A” with a
tension tester and deflect the belt 1/4". The force
required to get this deflection should range from 7 to
10 lbs.
2.
To adjust belt tension, adjust eyebolt (#1), as
necessary. This adjustment will increase or decrease
the tension on spring (#2). If more tension is needed
than the eyebolt can adjust take the tension spring
(#2) to next link in the tension chain (#3).
3.
Excessive tension on the belt may lead to premature
failure of belt and drive components. Excessive
tension on the belt may also lead to a safety hazard
to the operator or bystanders. Not enough tension on
the belt may lead to premature failure of the belt due
to excessive slipping.
!
WARNING
Excessive tension on the belt may lead to premature failure of
belt and drive components. Excessive tension on the belt may
also lead to a safety hazard to the operator or bystanders.
