Adjusting the Axle Height
Desired height-of-cut range can be obtained by adjusting
the rear axle and placing caster spacers above or below the
caster arm (see chart).
1. Stop engine and remove spark plug wire(s).
2. Loosen but do not remove the 2 axle pivot bolts and the
2 axle adjustment bolts (Fig. 22).
3. Place a jack under the rear center of the engine frame.
Raise the back end of the engine frame up enough to
remove front 2 axle adjustment bolts (Fig. 22).
4. Raise or lower the engine frame with the jack,so that
front 2 axle adjustment bolts can be installed in the
desired hole location (Fig. 22). A tapered punch can be
used to help align the holes.
5. Tighten all 4 bolts and lower the unit.
6. Adjust control rods and brake linkages as required.
Refer to Servicing the Brake on page 30 and Installing
the Traction Control Rod on page 14.
