Hour Meter Product Overview The hour meter records the number of hours the engine has operated. It operates when the engine is running. Use these times for scheduling regular maintenance (Figure 6). Fuel Gauge The fuel gauge is located with the hour meter and the bars light up when the ignition switch is on (Figure 6). The indicator light appears when the fuel level is low (approximately one gallon remaining in the fuel tank).
Ignition Switch Length: This switch is used to start the mower engine and has three positions: Start, Run and Off. Motion Control Levers The motion control levers are used to drive the machine forward, reverse, and turn either direction. The neutral lock position is used with the safety interlock system to engage and to determine neutral position. Close the fuel shut-off valve (under the seat) when transporting or storing the mower.
Operation DANGER In certain conditions during fueling, static electricity can be released causing a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property. • Always place gasoline containers on the ground away from your vehicle before filling.
Filling the Fuel Tank Breaking In a New Machine Note: Do not fill the fuel tank completely full. Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows the gasoline to expand. New engines take time to develop full power. Mower decks and drive systems have higher friction when new, placing additional load on the engine. Allow 40 to 50 hours of break-in time for new machines to develop full power and best performance. 1. Park the machine on level ground. 2.
DANGER Operating on wet grass or steep slopes can cause sliding and loss of control. Wheels dropping over edges can cause rollovers, which may result in serious injury, death or drowning. There is no rollover protection when the roll bar is down. Always keep the roll bar in the fully raised and locked position and use the seat belt. Read and follow the rollover protection instructions and warnings. To avoid loss of control and possibility of rollover: • Do not operate near drop-offs or near water.
Operating the Mower Blade Control Switch (PTO) The use of protective equipment for eyes, ears, feet and head is recommended. 1 2 The blade control switch (PTO) starts and stops the mower blades and any powered attachments. Engaging the Blade Control Switch (PTO) G009027 Figure 10 1. Wear safety glasses Note: Engaging the blade control switch (PTO) with the throttle position at half or less will cause excessive wear to the drive belts. 2.
Operating the Ignition Switch Starting and Stopping the Engine 1. Turn the ignition key to the Start position (Figure 16). When the engines starts, release the key. Starting the Engine Important: Do not engage starter for more than 5 seconds at a time. If the engine fails to start allow a 15 second cool-down period between attempts. Failure to follow these instructions can burn out the starter motor. 1. Raise the ROPS up and lock into place, sit on the seat and fasten the seat belt. 2.

Release the parking brake; refer to Releasing the Parking Brake in Operation. 2. Move the levers to the center, unlocked position. 3. To go forward, slowly push the motion control levers forward (Figure 23).
Adjusting the Height-of-Cut Pin The height-of-cut is adjusted from 1 to 5-1/2 inches (25 to 140 mm) in 1/4 inch (6 mm) increments by relocating the clevis pin into different hole locations. 1. Move the transport lock to the lock position. 2. Push on the deck lift pedal with your foot and raise the mower deck to the transport position (also the 5-1/2 inch (140 mm) cutting height position) (Figure 26). 3. To adjust, rotate the pin 90 degrees and remove the pin from the height-of-cut bracket (Figure 26). 4.
Adjusting the Flow Baffle Cam Locks This procedure is applicable only to machines with the flow baffle locks. Certain models will have nuts and bolts in-place of the flow baffle locks and can be adjusted the same. The mower discharge flow can be adjusted for different types of mowing conditions. Position the cam locks and baffle to give the best quality of cut. 1. Disengage the blade control switch (PTO), move the motion control levers to the neutral locked position and set the parking brake. Figure 27 1.
Position A This is the full rear position. The suggested use for this position is a follows. • • • • Use for short, light grass mowing conditions. Use in dry conditions. For smaller grass clippings. Propels grass clippings farther away from the mower. Figure 33 Positioning the Seat Figure 31 The seat can move forward and backward. Position the seat where you have the best control of the machine and are most comfortable. Position B To adjust, move the lever sideways to unlock seat (Figure 34).
Changing the Seat Suspension 2. Rotate the release valve levers vertically to push the machine. This allows hydraulic oil to by-pass the pump enabling the wheels to turn (Figure 37). The seat is adjustable to provide a smooth and comfortable ride. Position the seat where you are most comfortable. 3. Disengage parking brake before pushing. To adjust it, turn the knob in front either direction to provide the best comfort (Figure 36). g019768 1 Figure 36 1.
