Mower Maintenance

Pivoting (Tilting) the Front
Cutting Unit Upright
Note: Although not needed for normal maintenance
procedures, the front cutting unit can be pivoted (tilted) to an
upright position. Should you desire to tilt the cutting unit,
proceed as follows:
1. Raise the front cutting unit slightly off of the floor, set
the parking brake, and stop the engine. Remove the
ignition key.
2. Remove the hairpin cotter and clevis pin securing the
deck transport latch to the latch plate. Pivot latch
toward rear of deck.
3. Remove the hairpin cotter and clevis pin securing the
height-of-cut chains to the rear of the cutting unit.
4. Start the engine, slowly raise the front cutting unit, and
stop the engine. Remove the ignition key.
5. Grasp the front of the cutting unit and lift it to an
upright position.
6. Hold the cutting unit upright, fit the cable end over the
pin on the cutting unit lift arm and secure it with the
hairpin cotter (Figure

Adjusting 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 8 to 11 mm (5/16 to 7/16 inch).
That is the back of the blade plane is 8 to 11 mm (5/16 to
7/16 inch) 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.
Adjusting the Front Cutting Unit
1. Loosen the jam nuts on the top or bottom of the
height-of-cut chain U-bolt
2. Adjust the other set of nuts to raise or lower the rear of
the cutting unit and attain the correct cutting unit pitch.
3. Tighten the jam nuts.
