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.
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. Filling the Fuel Tank G009189 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. Overfilling may result in fuel leakage or damage to the engine or emission system (if equipped). 1 1.
Using the Rollover Protection System (ROPS) WARNING To avoid injury or death from rollover: keep the roll bar in the raised locked position and use the seat belt. Ensure that the rear part of the seat is secured with the seat latch. WARNING There is no rollover protection when the roll bar is in the down position. • Lower the roll bar only when absolutely necessary. • Do not wear the seat belt when the roll bar is in the down position. • Drive slowly and carefully.
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.

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 27). 3. To adjust, rotate the pin 90 degrees and remove the pin from the height-of-cut bracket (Figure 27).
Position A Adjusting the Flow Baffle Cam Locks This is the full rear position. The suggested use for this position is a follows. 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. • Use for short, light grass mowing conditions. • Use in dry conditions. • For smaller grass clippings. The mower discharge flow can be adjusted for different types of mowing conditions.
Unlatching the Seat • Allows increased ground speed in heavy conditions. • This position is similar to the benefits of the Toro SFS mower. Figure 36 1. Seat latch 2. Seat Using the Drive Wheel Release Valves Figure 34 WARNING Positioning the Seat Hands may become entangled in the rotating drive components below the engine deck, which could result in serious injury. The seat can move forward and backward. Position the seat where you have the best control of the machine and are most comfortable.
Transporting Machines 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. WARNING Driving on the street or roadway without turn signals, lights, reflective markings, or a slow moving vehicle emblem is dangerous and can lead to accidents causing personal injury.
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.
Mowing Direction shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease. Check the cutter blades daily for sharpness, and for any wear or damage. File down any nicks and sharpen the blades as necessary. If a blade is damaged or worn, replace it immediately with a genuine TORO replacement blade. Alternate mowing direction to keep the grass standing straight.
