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 in the ON position (Figure 6). The indicator light appears when the fuel level is low (approximately 1 gallon remaining in the fuel tank).
Choke Neutral-Lock Position Use the choke to start a cold engine. Pull the choke knob up to engage it. Use the NEUTRAL-LOCK position with the safety-interlock system to engage and to determine the NEUTRAL position. Blade-Control Switch (PTO) Fuel-Shutoff Valve Use the blade-control switch (PTO) to engage the electric clutch and drive the mower blades. Pull the switch up to engage the blades and release.
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.
Checking the Engine-Oil Level Add the correct amount of gasoline stabilizer/conditioner to the gasoline. Note: A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times. Before you start the engine and use the machine, check the oil level in the engine crankcase; refer to Checking the Engine-Oil Level (page 17).
3. Think Safety First Lower the roll bar to the down position (Figure 8). Please read all safety instructions and symbols in the safety section. Knowing this information could help you or bystanders avoid injury. DANGER Operating the machine on wet grass or steep slopes can cause sliding and loss of control. • Do not operate on slopes greater than 15 degrees. • Reduce speed and use extreme caution on slopes. • Do not operate the machine near water.
Setting the Parking Brake WARNING Parking brake may not hold machine parked on a slope and could cause personal injury or property damage. Do not park on slopes unless wheels are chocked or blocked g000963 Figure 9 1. Safe Zone—use the Z Master here on slopes less than 15 degrees or flat areas. 2. Danger Zone—use a walk-behind mower and/or a hand trimmer on slopes greater than 15 degrees, near drop-offs and water. 3.

Always use the FAST position when turning on the mower deck with the blade-control switch (PTO). g008946 Figure 15 Operating the Choke Use the choke to start a cold engine. 1. If the engine is cold, use the choke to start the engine. 2.
Operating the Ignition Switch 1. Turn the ignition key to the START position (Figure 17). Note: When the engines starts, release the key. 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. Note: You may need multiple attempts to start the engine when you start it the first time after the fuel system has been without fuel completely.
Starting the Engine 1. 2. 3. 4. 5. Raise the ROPS up and lock into place, sit on the seat, and fasten the seat belt. Move the motion controls to the NEUTRAL-LOCK position. Set the parking brake; refer to Setting the Parking Brake (page 19). Move the blade-control switch (PTO) to the OFF position (Figure 19). Move the throttle lever midway between the SLOW and FAST positions.
Understanding the Safety-Interlock System The safety-interlock system is designed to prevent the engine from starting unless: • The parking brake is engaged. • The blade-control switch (PTO) is disengaged. • The motion-control levers are in the NEUTRAL-LOCK position. The safety-interlock system also is designed to shut off the engine when the traction controls are moved from the locked position with the parking brake engaged or if you rise from the seat when the PTO is engaged.
Driving Forward or Backward position, and move the motion-control levers to the NEUTRAL-LOCK position. Now start the engine. While the engine is running, release the parking brake, engage the blade-control switch (PTO) and rise slightly from the seat; the engine should shut off. 4. 5. The throttle control regulates the engine speed as measured in rpm (revolutions per minute). Place the throttle control in the FAST position for best performance. Always operate in the full throttle position when mowing.
Driving Backward 1. Move the levers to the center, unlocked position. 2. To go backward, slowly pull the motion-control levers rearward (Figure 25). g008953 Figure 25 Stopping the Machine To stop the machine, move the traction-control levers to neutral, and then move them to the locked position, disengage the blade-control switch (PTO), and turn the ignition key to the OFF position. Set the parking brake when you leave the machine; refer to Setting the Parking Brake (page 19).
2. Push on the deck-lift pedal with your foot, and raise the mower deck to the transport position (also the 140 mm (5-1/2 inches) cutting height position) as shown in Figure 27. 3. To adjust, rotate the pin 90 degrees and remove the pin from the height-of-cut bracket (Figure 27). 4. Select a hole in the height-of-cut bracket corresponding to the height-of-cut desired, and insert the pin (Figure 27). 5. Push on the deck lift, pull back on the transport lock, and slowly lower the mower deck.
Adjusting the Flow Baffle Cam Locks This procedure is applicable only to machines with the flow-baffle locks. Certain models have nuts and bolts in place of the flow-baffle locks and can be adjusted the same. You can adjust the mower-discharge flow 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-LOCK position, and set the parking brake. 2.
Changing the Seat Suspension The seat adjusts to provide a smooth and comfortable ride. Position the seat where you are most comfortable. To adjust, turn the knob in front either direction to provide the best comfort (Figure 37). g005834 Figure 34 Positioning the Seat The seat moves forward and backward. Position the seat where you have the best control of the machine and are most comfortable. g019768 Figure 37 1. Seat-suspension knob To adjust, move the lever sideways to unlock the seat (Figure 35).
Using the Side Discharge Note: Make sure that the release valves are in the fully horizontal position when operating the machine or severe damage to the hydraulic system can occur. 1. 2. The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. Disengage the blade-control switch (PTO), turn the ignition key to the OFF position, move the levers to the NEUTRAL-LOCK position, apply the parking brake, and remove the key.
5. Use the tie-down loops on the machine to securely fasten it to the trailer or truck with straps, chains, cable, or ropes (Figure 39). WARNING Loading a machine onto a trailer or truck increases the possibility of tip-over and could cause serious injury or death. • Use extreme caution when operating a machine on a ramp. • Ensure that the ROPS is in the up position and use the seat belt when loading or unloading the machine. Ensure that the ROPS will clear the top of an enclosed trailer.
