Refer to Figure 8
of spacers for your desired height-of-cut setting.
Note:
You may use the shims in any
combination above or below the castor-arm hub
(as required) to achieve the desired height of
cut or cutting-unit level.
3. Push the castor spindle through the castor arm.
4. Install the shims (as they were originally
installed) and the remaining spacers onto the
spindle shaft.
5. Install the tensioning cap to secure the assembly.
Positioning the Height-of-Cut
Chain
1. Remove the pins that secure the height-of-cut
chains to the rear of the cutting unit
1. Height-of-cut chain
2. Refer to the height-of-cut decal to determine the
appropriate hole for your desired height of cut.
Note:
The decal is adjacent to each
height-of-cut plate.
3. Mount the height-of-cut chains to the desired
height-of-cut hole with the pin.
The pin should be installed in the lowest
height-of-cut chain link. The chain should hang
straight down (Figure

Pitch
A blade pitch of 6 to 9.5 mm (1/4 to 3/8 inch) is
recommended (i.e., the back of the blade plane is 6
to 9.5 mm (1/4 to 3/8 inch) higher than the front). A
pitch larger than 9.5 mm (3/8 inch) results in less

required power, larger clippings, and a poorer quality
of cut. A pitch less than 6 mm (1/4 inch) results in
more required power, smaller clippings and a better
quality of cut.
1. Park the machine on a level surface, lower the
cutting unit, engage the parking brake, shut off
the engine, and remove the key.
2. Set the cutting unit to the desired height-of-cut.
3. Rotate 1 blade so that it points straight forward.
4. Using a short ruler, measure from the floor to
the front tip of the blade. Rotate the blade tip to
the rear and measure from the floor to the tip
of the blade.
5. Subtract the front dimension from the rear
dimension to calculate the blade pitch.
6. Loosen the jam nuts at the top or bottom of the
