Specifications Operation Note: Specifications and design are subject to change without notice. Note: Determine the left and right sides of the machine from the normal operating position. Width: 48 inch Deck Adding Fuel Without Deck 45.3 inches (115.1 cm) Deflector Up 51.5 inches (130.8 cm) Deflector Down 63.1 inches (160.3 cm) • For best results, use only clean, fresh, unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method).
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. 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 Before you start the engine and use the machine, check the oil level in the engine crankcase; refer to Checking the Engine Oil Level. 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.
DANGER CAUTION Operating on wet grass or steep slopes can cause sliding and loss of control. This machine produces sound levels in excess of 85 dBA at the operators ear and can cause hearing loss through extended periods of exposure. Wheels dropping over edges can cause rollovers, which may result in serious injury, death or drowning. Wear hearing protection when operating this machine. There is no rollover protection when the roll bar is down.

individual ramps for each side of the unit (Figure 30). 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. If it is not possible to use one full width ramp, use enough individual ramps to simulate a full width continuous ramp. The ramp should be long enough so that the angles do not exceed 15 degrees (Figure 30).
Mow at Correct Intervals Normally, mow every four days. But remember, grass grows at different rates at different times. So to maintain the same cutting height, which is a good practice, mow more often in early spring. As the grass growth rate slows in mid summer, mow less frequently. If you cannot mow for an extended period, first mow at a high cutting height; then mow again two days later at a lower height setting. Cutting Speed To improve cut quality, use a slower ground speed in certain conditions.
