Product Overview 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 on (Figure 6). The indicator light appears when the fuel level is low (approximately one gallon remaining in the fuel tank). Safety Interlock Indicators There are symbols on the hour meter and the indicate with a black triangle that the interlock component is in the correct position (Figure 6).
Blade Control Switch (PTO) 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. 60 inch Deck 72 inch Deck Without Deck 53.0 inches (134.6 cm) 59.1 inches (150.1 cm) Deflector Up 61.7 inches (156.8 cm) 73.6 inches (187 cm) Deflector Down 75.7 inches (192.2 cm) 87.
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.
Always use the fast position when turning on the mower deck with the blade control switch (PTO). to start allow a 15 second cool-down period between attempts. Failure to follow these instructions can burn out the starter motor. Note: Additional starting cycles may be required when starting the engine for the first time after the fuel system has been without fuel completely.

• The blade control switch (PTO) is disengaged. • The motion control levers are in the neutral locked position The safety interlock system also is designed to stop 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. The hour meter has symbols to notify the user when the interlock component is in the correct position.
Using the Motion Control Levers the motion control levers to neutral lock position. Now start the engine. While the engine is running, center either motion control and move (forward or reverse); the engine should stop. Repeat for other motion control. 5. Sitting on the seat, disengage the parking brake, move the blade control switch (PTO) to off and move the motion control levers to neutral lock position. Try starting the engine; the engine should not crank.
Stopping the Machine To stop the machine, move the traction control levers to neutral and move to locked position, disengage the power take off (blade control switch (PTO), and turn the ignition key to off. Set the parking brake when you leave the machine; refer to Setting the Parking Brake in Operation. Remember to remove the key from the ignition switch. CAUTION Children or bystanders may be injured if they move or attempt to operate the tractor while it is unattended.
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.

Lock lever Figure 33 Position C Positioning the Flow Baffle This is the full open position. The suggested use for this position is as follows. • Use in tall, dense grass mowing conditions. • Use in wet conditions. • Lowers the engine power consumption. • Allows increased ground speed in heavy conditions. • This position is similar to the benefits of the Toro SFS mower.
Note: Make sure the release valves are in the fully horizontal position when operating the machine or severe damage to the hydraulic system can occur. 1. Disengage the PTO (blade control switch) and turn the ignition key to off. Move the levers to neutral locked position and apply parking brake. Remove the key. 2. Rotate the release valve levers vertically to push the machine. This allows hydraulic oil to by-pass the pump enabling the wheels to turn (Figure 37). G008962 Figure 35 3.
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. • Never put your hands or feet under the mower.
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.
