HEIGHT OF CUT ADJUSTMENT
Height of Cut (HOC) is adjusted by
positioning the front and rear wheels in a
series of mounting holes. See Figures 18 and
19.
Rear Wheel Height Adjustment
Rear wheel height is changed by raising or
lowering axles in the four available mounting
holes in frame. Place axles in upper holes for
a lower cut and lower holes for a higher cut.
Height-of-cut holes are spaced approximately
0.665" (17mm) apart. The mower is set-up at
the factory in the second from the lowest
position, for a 2.7" (69mm) cut height.
1. Stop engine, wait for all moving parts to
stop and hot parts to cool.
2. Place unit on a flat, level surface.
3. Disconnect spark plug wire from spark
plug.
4. Raise back of mower to lift rear wheels
off the ground. Support rear of mower
deck with jackstands, blocking or other
similar, stable support.
5. Hold rear axle bolt stationary with a
wrench while removing outer lock nut.
See Figures 17 and 18.
6. Remove wheel/tire assembly from axle
bolt.
7. Hold rear axle bolt stationary with a
wrench while removing inner nut. See
Figure 18.
8. Move each rear wheel axle bolt to
desired height-of-cut hole.
9. Install inner nut on axle bolt so flange of
nut is against mower frame. Hold rear
axle bolt stationary with a wrench while
tightening inner nut securely against
frame.
10. Install wheel/tire assembly on axle bolt.
11. Install outer lock nut on axle bolt so
flange of nut is against wheel. Hold rear
axle bolt stationary with a wrench while
tightening outer lock nut.
12. Connect spark plug wire to spark plug.
NOTE: Traction adjustment may be
necessary to correspond to rear wheel height
settings.
13. Adjust wheel drive traction as necessary.
Refer to the Wheel Drive Traction
Adjustment on page 25.
DANGER: Avoid injury from
rotating blade.
ALWAYS shut off engine, wait for
moving parts to stop and allow
engine to cool before adjusting
height of cut.
CAUTION: Both rear wheels
must be set at same height or
traction drive will not work
properly.
