Hour Meter Product Overview The hour meter records the number of hours the engine has operated. It operates when the engine is running. Use these times for scheduling regular maintenance (Figure 6). Fuel Gauge The fuel gauge is located within the hour meter, and the bars light up when the key switch is in the ON position (Figure 6). The indicator light appears when the fuel level is low (approximately 1 gallon remaining in the fuel tank).
Choke Control Attachments/Accessories Use the choke control to start a cold engine. A selection of Toro approved attachments and accessories is available for use with the machine to enhance and expand its capabilities. Contact your Authorized Service Dealer or authorized Toro distributor or go to www.Toro.com for a list of all approved attachments and accessories.
Operation • Do not fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers on the ground, away from your vehicle before filling. Note: Determine the left and right sides of the machine from the normal operating position. • Remove the equipment from the truck or trailer and refuel it while it is on the ground. If this is not possible, then refuel from a portable container rather than a fuel-dispenser nozzle.
Adding Fuel Note: Do not fill the fuel tank completely full. The empty space in the tank allows the fuel to expand. Recommended Fuel • For best results, use only clean, fresh (less than 30 days old), unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method). • Ethanol: Gasoline with up to 10% ethanol (gasohol) or 15% MTBE (methyl tertiary butyl ether) by volume is acceptable. Ethanol and MTBE are not the same. Gasoline with 15% ethanol (E15) by volume is not approved for use.
Using the Rollover-Protection System (ROPS) WARNING To avoid injury or death from rollover, keep the roll bar in the fully raised, locked position and use the seat belt. Ensure that the seat is secured to the machine. 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. • Raise the roll bar as soon as clearance permits.
Testing the Safety-Interlock System Using the Safety-Interlock System Service Interval: Before each use or daily WARNING Test the safety-interlock system before you use the machine each time. If the safety system does not operate as described below, have an Authorized Service Dealer repair the safety system immediately. If the safety-interlock switches are disconnected or damaged, the machine could operate unexpectedly, causing personal injury. 1.
Positioning the Seat Changing the Seat Suspension The seat can move forward and backward. Position the seat where you have the best control of the machine and are most comfortable (Figure 10). The seat is adjustable to provide a smooth and comfortable ride. Position the seat where you are most comfortable. To adjust it, turn the knob in front either direction to provide the best comfort (Figure 12).
• Keep your hands and feet away from the cutting units. Keep clear of the discharge opening at all times. • Look behind and down before backing up to be sure of a clear path. • Use care when approaching blind corners, shrubs, g229846 Figure 13 trees, or other objects that may obscure your vision. 1. Wear hearing protection. • Do not mow near drop-offs, ditches, or embankments. The machine could suddenly roll over if a wheel goes over the edge or if the edge gives way.
Operating the Parking Brake distance (twice the width of the machine) between the machine and any hazard. Use a walk-behind machine or a hand trimmer to mow the grass in these areas. Always engage the parking brake when you stop the machine or leave it unattended. • Avoid starting, stopping, or turning the machine on slopes. Avoid making sudden changes in speed or direction; turn slowly and gradually.
Operating the Mower Operating the Choke Blade-Control Switch (PTO) Use the choke to start a cold engine. The blade-control switch (PTO) starts and stops the mower blades and any powered attachments. Engaging the Blade-Control Switch (PTO) 1. Pull up the choke knob to engage the choke before using the key switch (Figure 20). 2. Push down the choke knob to disengage the choke after the engine has started (Figure 20).
Starting the Engine Shutting Off the Engine Important: Do not engage starter for more than 5 seconds at a time. If the engine fails to start, wait 15 seconds between attempts. Failure to follow these instructions can burn out the starter motor. CAUTION Children or bystanders may be injured if they move or attempt to operate the machine while it is unattended. Note: You may need multiple attempts to start the engine the first time after adding fuel to an empty fuel system.
Using the Motion-Control Levers WARNING The machine can spin very rapidly. You may lose control of the machine and cause personal injury or damage to the machine. • Use caution when making turns. • Slow the machine down before making sharp turns. Driving Forward Note: The engine shuts off when you move the traction-control with the parking brake engaged. To stop the machine, pull the motion-control levers to the NEUTRAL position. 1.
Driving Backward Using the Side Discharge 1. Move the levers to the center, unlocked position. 2. To go backward, slowly pull the motion-control levers rearward (Figure 25). The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. DANGER Without a grass deflector, discharge cover, or a complete grass-catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris.
Adjusting the Height of Cut Adjusting the Height-of-Cut Pin Using the Transport Lock The height-of-cut is adjusted from 25 to 140 mm (1 to 5-1/2 inches) in 6 mm (1/4 inch) increments by relocating the clevis pin into different hole locations. The transport lock has 2 positions, and is used with the deck-lift pedal. There is a LOCK position and an UNLOCK position for the transport position of the mower deck (Figure 26). 1. Move the transport lock to the lock position. 2.
Adjusting the Anti-Scalp Rollers Whenever you change the height-of-cut, adjust the height of the anti-scalp rollers. 1. Park the machine on a level surface, disengage the blade-control switch, and engage the parking brake. 2. Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. 3. g029957 Figure 30 Adjust the anti-scalp rollers as shown in Figure 28, Figure 29, and Figure 30. 1.
