Leveling the Mower
Refer to Figure 4-1:
NOTE: Tractor & mower should be on level ground.
1. Set lower hitches and upper floating hitch, as shown.
2. Start tractor and raise mower while watching tractor
draw bar (if not removed) to make sure it does not
interfere with driveline and mower.
3. Slowly lower 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.
4. Set park brake, turn off tractor, and remove key.
5. Rotate blades parallel to direction of travel.
6. Measure clearance from the blade cutting edge to
the ground at the front and rear of the mower. These
two measurements should be equal or the blade at
the front should not be more than 1/2" lower than the
blade at the rear. The rear blade should not be lower
than the front blade.

!
WARNING
Always disengage PTO, place tractor in park or set park
brake, shut tractor engine off, remove switch key, and wait for
blades to come to a complete stop before dismounting from
tractor to make adjustments!
!
CAUTION
Wear a pair of gloves when checking cutting height. Avoid
direct contact with cutting edge of blade.
1. Using the tractor, raise mower off the ground, and
support under it with secure blocking to keep the
mower from drifting down during maintenance.
2. Holding wheel and yoke assembly up, remove quick-
lock pin from top of gauge wheel spindle.
3. 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 of this page.
3-Point Hitch Adjustments
Refer to Figure 4-1:
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 in.
Belt Tension
!
WARNING
Excessive belt tension can lead to premature damage/
breakage of belt and drive component and is a safety hazard
to operator and bystanders.
!
CAUTION
Belt drive system is under spring tension; use care to avoid
bodily harm while making adjustments to the belt!
Refer to Figure 4-2:
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
20829
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.
