Blade-Control Switch (PTO) Specifications The blade-control switch (PTO) is used to engage the electric clutch and drive the mower blades. Pull the switch up to engage the blades and release. To disengage the blades, push the blade-control switch (PTO) down or move a motion-control lever into the neutral lock position. Note: Specifications and design are subject to change without notice. Width: Ignition Switch This switch is used to start the mower engine and has 3 positions: START , RUN and OFF.
Operation DANGER In certain conditions during fueling, static electricity can cause 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. • Do not fill gasoline containers inside a vehicle or on a truck or trailer bed, because interior carpets or plastic truck-bed liners may insulate the container and slow the loss of any static charge.
Filling the Fuel Tank chance of varnish deposits in the fuel system, use fuel stabilizer at all times. 1. Park the machine on level ground. 2. Shut the engine off and set the parking brake. 3. Clean around the fuel-tank cap and remove it. Add regular unleaded gasoline to the fuel tank until the level is 6 to 13 mm (1/4 to 1/2 inch) below the bottom of the filler neck. This space in the tank allows the gasoline to expand. Do not fill the fuel tank completely full; refer to (Figure 7).
Checking the Engine-Oil Level 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 38). Breaking in a New Machine 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.
Think Safety First 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. g000963 Figure 9 • Do not operate the machine near water. 1. Safe Zone—use the Z Master here on slopes less than 15 degrees or flat areas. 2.
Setting the Parking Brake WARNING The parking brake may not hold a machine parked on a slope and could cause personal injury or property damage. Do not park the machine on slopes unless the wheels are chocked or blocked. g008945 Figure 13 Disengaging the Blade-Control Switch (PTO) g027334 Figure 11 g009174 Figure 14 Releasing the Parking Brake Operating the Throttle You can move the throttle control between FAST and SLOW positions (Figure 15).
Starting and Stopping the Engine 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 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.
Understanding the Safety-Interlock System Let the engine idle at slow throttle (turtle) for 60 seconds before turning the ignition switch off. 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.

4. Disengage parking brake before pushing. DANGER Without a grass deflector, discharge cover, or complete grass catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris. Contact with rotating mower blade(s) and thrown debris will cause injury or death. • Never remove the grass deflector from the mower because the grass deflector routes material down toward the turf. If the grass deflector is ever damaged, replace it immediately.
Transporting the Machine Loading the Machine Use a heavy-duty trailer or truck to transport the machine. Ensure that the trailer or truck has all necessary brakes, lighting, and marking as required by law. Please carefully read all the safety instructions. Knowing this information could help you, your family, pets, or bystanders avoid injury. Use extreme caution when loading or unloading machines onto a trailer or a truck. Use a full-width ramp that is wider than the machine for this procedure.
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. • Use only a full-width ramp; do not use individual ramps for each side of the machine.
Cutting Long Grass Operating Tips If the grass is ever allowed to grow slightly longer than normal, or if it contains a high degree of moisture, raise the cutting height higher than usual and cut the grass at this setting. Then cut the grass again using the lower, normal setting. Using the Fast Throttle Setting For best mowing and maximum air circulation, operate the engine at the FAST throttle position.
