Adjusting Height-of-Cut
A 25mm to 108mm (1” to 4-1/4”) range for
height-of-cut can be achieved by adjusting blade
spacers, rear axle height and front castor spacers. Use
the Height-of-Cut chart on page 26 to select the
combination required
Adjust Blade Height
Blades are adjusted by using the four, 6.35mm (1/4”)
spacers found on the blade spindle bolts. This allows
a range, in 6.35mm (1/4”) increments, of cutting
height in any axle position. The same number of
blade spacers must be used on all blades to achieve a
level cut (two above and two below, one above and
three below, etc.).
1. Stop engine and remove spark plug wire(s).
2. Hold blade bolt and remove nut. Slide bolt
down, through spindle, and change spacers as
required (Fig. 19).
3. Insert bolt, add extra spacer(s), and secure with
thin washer and nut (Fig. 19).
4. Torque blade bolt to 101–108 NSm
(75–80 ft. lb.).

Adjust 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, remove spark plug wire(s) and belt
guard (Fig. 20).
2. Loosen but do not remove the (2) axle pivot
bolts and the (2) axle adjustment bolts (Fig. 20).
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. 20).
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. 20). 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: Assembly and Brake.
IMPORTANT: It will be necessary to adjust
control rods and brake linkage when
changing axle positions for proper traction
and brake function.
