Side to Side Leveling
If the cut is uneven, the mower may need leveling.
Unequal or improper tire pressure may also cause an
uneven cut. See CHECK TIRE PRESSURE.
1. With the mower installed, place the rider on a
smooth, level surface such as a concrete floor. Turn
the front wheels straight forward. Turn the engine off,
set the ground speed control levers to PARK, and
wait for all moving parts to stop.
2. Check for bent blades and replace if necessary.
3. Check the tire pressures. See CHECK TIRE
PRESSURE.
4. Set the cutting height to mid position. Arrange the
mower blades so that they are pointing from side-to-
side (Figure 36).
5. Measure the distance between the tips of the outside
blades and the ground (Figures 35 & 36). If there is
more than 1/8" (3mm) difference between the
measurements on each side, proceed to step 6. If the
difference is 1/8" (3mm) or less, proceed to Front To
Back Leveling.
6. See Figure 37. Side-to-side leveling is accomplished
using the threaded rods (A, Figure 37) and trunnion
(B) on the right and left rear sides of the mower deck.
Loosen the jam nuts (C) and adjust the nuts up or
down to adjust the mower level. When complete,
tighten the jam nuts against the trunnion to lock the
adjustment in place.
WARNING
Before inspecting or adjusting the mower, turn
the mower blades OFF, turn the ignition switch
OFF, and allow all moving parts to stop. Remove
ignition key, then disconnect the spark plug wire
and fasten it away from the spark plug.
