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 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.
CAUTION 1 This machine produces sound levels in excess of 85 dBA at the operators ear and can cause hearing loss through extended periods of exposure. 2 Wear hearing protection when operating this machine.

Stopping the Engine The Safety Interlock System CAUTION CAUTION Children or bystanders may be injured if they move or attempt to operate the tractor while it is unattended. If safety interlock switches are disconnected or damaged the machine could operate unexpectedly causing personal injury. • Do not tamper with the interlock switches. • Check the operation of the interlock switches daily and replace any damaged switches before operating the machine.
Using the Motion Control Levers 1. Sitting on the seat, engage the parking brake and move the blade control switch (PTO) to on. Try starting the engine; the engine should not crank. 2. Sitting on the seat, engage the parking brake and move the blade control switch (PTO) to off. Move either motion control lever (out of neutral locked position). Try starting the engine; the engine should not crank. Repeat for other control lever. 3.
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 1-1/2 to 4-1/2 inches (38 to 114 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 4-1/2 inch (114 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).
Adjusting the Flow Baffle Cam Locks 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. The mower discharge flow can be adjusted for different types of mowing conditions. Position the cam locks and baffle to give the best quality of cut. 1. Disengage the blade control switch (PTO), move the motion control levers to the neutral locked position and set the parking brake. 2.
Position A • Allows increased ground speed in heavy conditions. • This position is similar to the benefits of the Toro SFS mower. This is the full rear position. The suggested use for this position is a follows. • Use for short, light grass mowing conditions. • Use in dry conditions. • For smaller grass clippings. • Propels grass clippings farther away from the mower. Figure 34 Figure 32 Positioning the Seat The seat can move forward and backward.
WARNING DANGER The engine and hydraulic drive units can become very hot. Touching a hot engine or hydraulic drive units can cause severe burns. 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. Allow the engine and hydraulic drive units to cool completely before accessing the drive wheel release valves.
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 38). 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.
Operating Tips WARNING Loading a unit onto a trailer or truck increases the possibility of backward tip-over and could cause serious injury or death. 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.
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.
Maintenance Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 8 hours • Change the engine oil. After the first 100 hours • Check the wheel hub slotted nut torque. • Check the torque for wheel lug nuts. • Check the park brake adjustment.
