Leveling the Mower at Three
Positions
Important
There are only three measuring positions
needed to level the mower.
Setting Up 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. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
5. Check tire pressure of all four tires. If needed, adjust
to 13 psi (90 kPa)
6. Lower the mower to the 3 inch (76 mm) height–of–cut
position.
7. Inspect the four chains. The chains need to have
tension.
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 on page 47.
If one front chain is loose, raise (tighten) the front
support arm for that chain. Refer to Adjusting the
Front–to–Rear Mower Pitch on page 47.
Leveling the Mower Side–to–Side
1. Position the right blade front-to-rear (Fig. 61).

2. Measure the right blade at the B location (Fig. 61),
from a level surface to the cutting edge of the blade
tips (Fig. 62).
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 (Fig. 61).
5. Measure the left blade at the C location (Fig. 61), from
a level surface to the cutting edge of the blade tips
(Fig. 62).
6. Record this measurement. This measurement needs to
be 3–1/8 to 3–1/4 inches.

7. If the measurements at positions B or C are not
correct, loosen the bolt attaching the rear chain to the
rear support arm (Fig. ).
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.
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.
