Mower Deck
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 62).
2. Measure the right blade at the B location, from
a level surface to the cutting edge of the blade
tip (Figure 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 (Figure 62).
5. Measure the left blade at the C location
(Figure 62), 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).
Figure 62
1. Measure here from blade
to hard surface
2. Measure at B and C
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 63).
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 63).
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.
