needed to level the mower.
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
the pressure to 90kPa (13 psi).
5. Lower the mower to the 76 mm (3 inch) height-of-cut
position.

support arm for that chain. Refer to
