Operation Note: Determine the left and right sides of the machine from the normal operating position. Controls Motion Control Levers The motion control levers located on each side of the console control the forward and reverse motion of the machine. Moving the levers forward or backward turns the wheel on the same side forward or reverse respectively.
Operation Note: The LCD indicator appears in the message display on the RH console when the park brake is engaged (see Figure 9). Pull the lever up and rearward to engage the brake. Depress the release button and push downward to disengage the brake.
Fuel Shut-Off Valve Located behind and below the seat. The fuel shut-off valve is used to shut off the fuel when the machine will not be used for a few days, during transport to and from the jobsite, and when parked inside a building.
Operation Deck Lift Pedal Located at the right front corner of the floor pan. Push the pedal forward with your foot to raise the cutting deck. Allow the pedal to move rearward to lower the cutting deck to the cut height that has been set.
the roll bar may need to be pushed forward or pulled rearward to get both knobs fully engaged (see Figure 13). Figure 13 1. Engaged 2. Partially engaged — Do Not operate with ROPS in this condition. Important: Always use the seat belt with the roll bar in the operate (raised) position.

Maintenance 2. Slide the cover plate backward or forward to adjust the travel of the lever and tighten the screws. 3. Drive the machine and check the full forward tracking. 4. Repeat steps 1 through 3 until desired tracking is obtained. Figure 35 RH Motion Control Shown 1.
Cleaning Clean Engine and Exhaust System Area Service Interval: Before each use or daily (May be required more often in dry or dirty conditions.) CAUTION Excessive debris around engine cooling air intake and exhaust system area can cause engine, exhaust area, and hydraulic system to overheat which can create a fire hazard.
Maintenance CAUTION Raising the mower deck for service or maintenance relying solely on mechanical or hydraulic jacks could be dangerous. The mechanical or hydraulic jacks may not be enough support or may malfunction allowing the unit to fall, which could cause injury. Do Not rely solely on mechanical or hydraulic jacks for support.
Troubleshooting Important: It is essential that all operator safety mechanisms be connected and in proper operating condition prior to mower use. When a problem occurs, do not overlook the simple causes. For example: starting problems could be caused by an empty fuel tank. The following table lists some of the common causes of trouble.
