Check Tire Pressure

c CAUTION: Avoid injury! Explosive separation of tire and rim parts is possible when they are serviced incorrectly: · Do not attempt to mount a tire without the proper equipment and experience to perform the job. · Do not inflate the tires above the recommended pressure. · Do not weld or heat a wheel and tire assembly. Heat can cause an increase in air pressure resulting in an explosion. Welding can structurally weaken or deform the wheel. · Do not stand in front of or over the tire assembly when inflating. Use a clip-on chuck and extension hose long enough to allow you to stand to one side.

1. Check tires for damage.

2. Check tire pressure with an accurate gauge.

3. Add or remove air, if necessary.

Install Rear Wheel Assembly

Assemble Cutting Units

The Model 2500A Greensmower is shipped from the factory without the cutting units installed. The hydraulic reel motors and cutting reel yokes are shipped with the greensmower.

Refer to installation instructions packaged with the cutting units when installing the cutting units and cutting unit yokes onto the greensmower. Retain these instructions with the operator's manual for future reference.

Hardware used to install the cutting units and cutting unit yokes onto the greensmower is included in the greensmower parts bag. Hardware must be retained for cutting unit and cutting unit yoke assembly procedures.

Check and Adjust Lift Arm Stops

NOTE: Lift arm stop adjustment must be performed at initial set-up and when changing tire sizes.

Check Adjustment
