Pivoting (Tilting) the Front

1. With the help of another person holding the front of
the mower deck, remove the block of wood.
2. Sit on the seat, start the engine, and lower the mower
deck until it is slightly off the floor.
3. Secure the height-of-cut chains to the rear of the
mower deck.
4. Connect the damper assembly and secure it with the

Adjusting the Mower-Deck
Pitch
Measuring the Mower-Deck Pitch
The mower-deck pitch is the difference between the
height-of-cut from the front of the blade plane to that of the
back of the blade plane. Set a blade pitch of 7.5 mm (0.3
inch); i.e., the back of the blade plane should be 7.5 mm (0.3
inch) higher than the front of the blade plane.
1. Position the machine on a level surface on the floor.
2. Set the mower deck to the desired height of cut.
3. Ensure that the winglets are level to the front deck and
the front deck is level side to side.
Adjusting the Front-Mower-Deck Pitch
1. Rotate the 2 outer, front blades and the winglet blades,
so that they point straight forward
1. Use 1 of these blades for
measuring the front-blade
height.
2. Using a short ruler, measure from the floor to the front
tip of the front blade and record this dimension.
3. Measure from the floor to the back tip of the winglet
blade and record this dimension.
4. Subtract the front dimension from the rear dimension
to calculate the blade pitch.
5. Loosen the jam nuts on the top or bottom of the
height-of-cut chain U-bolt
Note: Loosen or tighten the height-of-cut chain nuts
equally so that the deck remains level from side to side.
