slope.
Always set the parking brake when you stop the machine
or leave it unattended. If the parking brake does not hold
securely, an adjustment is required.

Service Interval: Before each use or daily
Important: Ensure the mower is on a level surface when
checking and adjusting the brake.
1. Park the machine on a level surface, disengage the PTO.
2. Stop the engine, remove the key, and wait for all moving
parts to stop before leaving the operating position.
3. Release the parking brake; refer to
Releasing the Parking Brake (page 15).
4. Check the tire pressure; refer to
Checking the Tire Pressure (page 39).

ensure that the distance is between 3 and 6
