Leveling the Mower
If the cut is uneven, the mower may need leveling.
Unequal or improper tire pressure may also cause an
uneven cut. Make sure tire pressure is correct as
specified in CHECK TIRE PRESSURE section.
SIDE-TO-SIDE LEVELING
1. With the mower installed, place the tractor on a
smooth, level surface such as a concrete floor. Turn
the front wheels straight forward.
2. Check for bent blades and replace if necessary.
3. Place the mower in mid-cut position. Arrange the
outside mower blades so that they are pointing from
side-to-side.
4. Measure the distance between the outside tips of
each blade and the ground. If there is more than 1/8”
(3 mm) difference between the measurements on
each side, proceed to Step 5. If the difference is 1/8”
(3 mm) or less, proceed to Step 6.
5. Loosen the outside nut (
A
, Figure 31). Turn the
eccentric nut (
B
) to raise or lower left-hand side of
mower. When mower is level, hold the eccentric nut
while tightening the outside nut.
NOTE: When using a turbo collection system, raise the
discharge side of the mower approximately 1/4” (6 mm)
to compensate for turbo assembly weight. Check the
level of the cut grass and adjust the 1/4” (6 mm)
measurement as necessary for a smooth, even cut.
4. Remove the old belt and replace with a new one.
Make sure the belt is seated in the pulley grooves.
5. Move the idler arm release lever to release tension
on the PTO belt and install on the engine PTO pulley
and mower PTO pulley (
D
) as shown.
6. Reinstall the right and left belt covers.
7. Run the mower under a no-load condition for about 5
minutes prior to using.
ARBOR DRIVE BELT REPLACEMENT

E
, Figure 30)
