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.
