4. Push the castor spindle through the castor arm. Install
the shims (as they were originally installed) and the
remaining spacers onto the spindle shaft. Install the
tensioning cap to secure the assembly.
5. Remove the hair pin and clevis pin securing the height
of cut collar to the height of cut rod on the rear of the
cutting unit (Fig. 8).

7. Secure the adjustment with the clevis pin and hair pin.
Note: Position the head of the clevis pin toward the front
of the deck, if possible.
Note: When using 1 in. (25 mm), 1-1/2 in. (38 mm), or
occasionally 2 in. (51 mm) height–of–cut, move the skids
and roller to the highest holes.

Adjust the Cutting Unit Pitch

Measuring the Cutting Unit Pitch
Cutting unit pitch is the difference in height-of-cut from the
front of the blade plane to the back of the blade plane. Toro
recommends a blade pitch of 1/4 in. (6 mm). That is the
back of the blade plane is 1/4 in. (6 mm) higher than the
front.
1. Position the machine on a level surface on the shop
floor.
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 on the bottom of the height-of-cut
rods (Fig. 10).

7. Rotate the height-of-cut rods to raise or lower the rear
of the cutting unit and attain the correct cutting unit
pitch.
