Maintenance
Leveling the Mower at Three
Positions
Important: There are only three measuring
positions needed to level the mower.
Preparing the Machine
1. Position mower on a flat surface.
2. Disengage the PTO, move the motion control levers
to the neutral locked position and set the parking
brake.
3. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
4. Check tire pressure of all four tires. If needed, adjust
to 13 psi (90 kPa)
5. Lower the mower to the 3 inch (76 mm) height-of-cut
position.
6. Inspect the four chains. The chains need to have
tension.
Note: Adjust the rear chains to the top of the slot,
where they are attached to the mower.
• If one rear chain is loose, lower (loosen) the front
support arm on the same side. Refer to Adjusting
the Front-to-Rear Mower Pitch.
• If one front chain is loose, raise (tighten) the front
support arm for that chain. Refer to Adjusting the
Front-to-Rear Mower Pitch.
Leveling the Mower Side-to-Side
1. Position the right blade front-to-rear (Figure 60).
2. Measure the right blade at the B location, from a
level surface to the cutting edge of the blade tip
(Figure 60).
3. Record this measurement. This measurement needs
to be 3-1/8 to 3-1/4 inches.
4. Position the left blade front-to-rear (Figure 60).
5. Measure the left blade at the C location (Figure 60),
from a level surface to the cutting edge of the blade
tip .
6. Record this measurement. This measurement needs
to be 3-1/8 to 3-1/4 inches (79 to 83mm).
1. Measure here from blade
to hard surface
7. If the measurements at positions B or C are not
correct, loosen the bolt attaching the rear chain to
the rear support arm (Figure 61).
8. Loosen the jam nut under the rear support arm and
adjust the adjustment bolt to get a measurement of
3-1/8 to 3-1/4 inches (Figure 61).
Note: It is recommended that both sides of the
mower are adjusted the same distance.
9. Tighten the jam nut under the rear support arm
and tighten the bolt securing the chain to the rear
support arm.
10. Adjust the opposite side if needed.
