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 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. 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.
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.
Releasing the Parking Brake CAUTION This machine produces sound levels in excess of 85 dBA at the operators ear and can cause hearing loss through extended periods of exposure. 1 2 Wear hearing protection when operating this machine. The use of protective equipment for eyes, ears, feet and head is recommended. 1 G016995 Figure 12 2 Operating the Mower Blade Control Switch (PTO) G009027 Figure 10 1.
Operating the Throttle 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.

Using the Drive Wheel Release Valves WARNING Hands may become entangled in the rotating drive components below the engine deck, which could result in serious injury. Stop the engine, remove the key, and allow all moving parts to stop before accessing the drive wheel release valves. WARNING The engine and hydraulic drive units can become very hot. Touching a hot engine or hydraulic drive units can cause severe burns.
Loading Machines Use extreme caution when loading units on trailers or trucks. One full width ramp that is wide enough to extend beyond the rear tires is recommended instead of individual ramps for each side of the unit (Figure 39). The lower rear section of the tractor frame extends back between the rear wheels and serves as a stop for tipping backward. Having a full width ramp provides a surface for the frame members to contact if the unit starts to tip backward.

Swing the stand foot out front and slide stand toward machine, into the bottom of slot (Figure 41 and Figure 42). Using the Z Stand® (CP Models Only) The Z Stand® raises the front end of the machine to allow you to clean the mower and remove the blades. WARNING The machine could fall onto someone and cause serious injury or death.
Operating Tips WARNING Parking brake may not hold machine parked on Z Stand and could cause personal injury or property damage. Fast Throttle Setting For best mowing and maximum air circulation, operate the engine at the fast throttle position. Air is required to thoroughly cut grass clippings, so do not set the height-of-cut so low as to totally surround the mower by uncut grass. Always try to have one side of the mower free from uncut grass, which allows air to be drawn into the mower.
Long Grass 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. When Stopping If the machine's forward motion must be stopped while mowing, a clump of grass clippings may drop onto your lawn. To avoid this, move onto a previously cut area with the blades engaged.
