Assemble Cutting Units

The Model 2500 Tri-Plex 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 Tire Pressure

c CAUTION: Avoid injury! Explosive separation of a tire and rim parts can cause serious injury or death: · DO NOT attempt to mount a tire without the proper equipment and experience to perform the job. · Always maintain the correct tire pressure. DO NOT inflate the tires above the recommended pressure. Never weld or heat a wheel and tire assembly. The heat can cause an increase in air pressure resulting in a tire explosion. Welding can structurally weaken or deform the wheel. · When inflating tires, use a clip-on chuck and extension hose long enough to allow you to stand to one side and NOT in front of or over the tire assembly. · Check tires for low pressure, cuts, bubbles, damaged rims or missing lug bolts and nuts.

1. Check tires for damage.

2. Check tire pressure with an accurate gauge.

3. Add air, if necessary:

Check Machine Safety Interlock System

Perform safety system check to make sure the electronic safety interlock circuit is functioning properly. (See Testing the Safety Interlock System in the Operating Machine section.)

Check and Adjust Lift Arm Stops

NOTE: Lift arm stop adjustment must be performed when changing tire sizes.

Before checking the lift arm stop adjustment:

· Reduce inflation pressure in all tires to 69-83 kPa (10-12 psi). Tires are shipped over inflated.

· Install all three cutting units.

Check Adjustment

1. Turn key switch to the RUN position.

2. Push Raise/Lower lever FORWARD to relieve hydraulic pressure in the front and center lift arm cylinders.

3. Push down front and center lift arms.

M97967

4. Turn key switch to the STOP position.

5. Measure distance (A) between the center of each yoke ball joint and the ground.

· All three yoke ball joints should be 225 5 mm (8.86 in. .20 in.) above the ground with the lift arm down stop plates (B) contacting the stop bolts (C).
