Setting Up the Machine
1. Position the 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.
• 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

a level surface to the cutting edge of the blade
tip (Figure 71).
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 71).
5. Measure the left blade at the C location
(Figure 71), from a level surface to the cutting
edge of the blade tip .

arm and adjust the adjustment bolt to get
a measurement of 3-1/8 to 3-1/4 inches
(Figure 72).

the mower are adjusted the same distance.
9. Tighten the jam nut under the rear support
