Mower Maintenance

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

Adjusting the Mower-Deck
Pitch
Measuring the Mower-Deck Pitch
Mower-deck pitch is the difference in height of cut from the
front of the blade plane to the back of the blade plane. Use 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 mower deck to the desired height of cut.
3. Rotate a blade to point straight forward.
4. Using a short ruler, measure from the floor to the front
tip of the blade.
5. Rotate the blade tip to the rear and measure from the
floor to the tip of the blade.
6. Subtract the front dimension from the rear dimension
to calculate the blade pitch.
Adjusting the Front Mower-Deck Pitch
1. Loosen the jam nuts at 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 mower deck and attain the correct mower-deck
pitch.
3. Tighten the jam nuts.
