Specifications Note: Specifications and design are subject to change without notice.
Fuel Safety Operation Use extreme care when handling fuel. Note: Determine the left and right sides of the machine from the normal operating position. DANGER In certain conditions gasoline is extremely flammable and vapors are explosive. Before Operation A fire or explosion from gasoline can burn you, others, and cause property damage. Before Operation Safety • Fill the fuel tank outdoors on level ground, in an open area, when the engine is cold. Wipe up any gasoline that spills.
To help prevent fires: DANGER • Keep engine and engine area free from In certain conditions during fueling, static electricity can be released causing a spark which can ignite gasoline vapors. A fire or explosion from gasoline can burn you and others and cause property damage. • Always place gasoline containers on the ground away from your vehicle before filling.
Breaking in a New Machine the chance of varnish deposits in the fuel system, use fuel stabilizer at all times. 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. Filling the Fuel Tank 1. Park the machine on a level surface. 2. Engage the parking brake. 3. Shut off the engine and remove the key. 4.

Understanding the Safety-Interlock System The safety-interlock system is designed to prevent the engine from starting unless the following occurs: • The parking brake is engaged.
Positioning the Seat 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. 1. Sit on the seat, engage the parking brake, and move the blade-control switch (PTO) to the ON position. Try starting the engine; the engine should not start. 2. Sit on the seat, engage the parking brake, and move the blade-control switch (PTO) to the OFF position.
Adjusting the Rear-Shock Assemblies Machines with MyRide™ Suspension System Only The MyRide™ suspension system adjusts to provide a smooth and comfortable ride. You can adjust the rear 2-shock assemblies to quickly and easily change the suspension system. Position the suspension system where you are most comfortable. g227752 The slots for the rear-shock assemblies have detent positions for reference. You can position the rear-shock assemblies anywhere in the slot, not just in the detent positions.
Using Attachments and Accessories WARNING Engine exhaust contains carbon monoxide, which is an odorless deadly poison that can kill you. Use only Toro approved attachments and accessories. If you add more than 1 accessory mount kit (i.e., bucket kit or universal mount kit) to both of the locations shown in Figure 17, add a front weight kit. Contact an Authorized Service Dealer for the front weight kit.
– Be alert and turn the machine off if children enter the area. WARNING Hands, feet, hair, clothing, or accessories can become entangled in rotating parts. Contact with the rotating parts can cause traumatic amputation or severe lacerations. – Do Not operate the machine without guards, shields, and safety devices in place and working properly. – Keep hands, feet, hair, jewelry, or clothing away from rotating parts.
Rollover Protection System (ROPS) Safety A Rollover Protection System (roll bar) is installed on the machine. WARNING There is no rollover protection when the roll bar is down. Wheels dropping over edges, ditches, steep banks, or water can cause rollovers, which may result in serious injury, death or drowning. • Do Not remove the ROPS. • Keep the roll bar in the raised and locked position and use seat belt. g221745 Figure 18 • Lower the roll bar only when absolutely necessary. 1.
Disengaging the Parking Brake Entering the Operator’s Position Use the mower deck as a step to get into the operator’s position (Figure 19). g192635 g029797 Figure 21 Figure 19 1. Step here. Operating the Parking Brake Always engage the parking brake when you stop the machine or leave it unattended. Engaging the Parking Brake Park the machine on a level surface.
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 25). 2. Push down the choke knob to disengage the choke after the engine has started (Figure 25).
Starting the Engine Shutting Off the Engine Note: A warm or hot engine may not require choking. Note: Refer to Figure 41 to determine which engine you have.

If the engine fails to start, wait 10 seconds before operating the engine starter again.
Shutting Off Toro Engines Using the Motion-Control Levers Note: Ensure the throttle is in the FAST position before shutting off the engine. c:\data\documentum\checkout\g004532 Figure 29 g037049 Figure 28 1. Motion-control lever—NEUTRAL-LOCK position 4. Backward 2. Center, unlocked position 5. Front of machine 3. Forward Important: Make sure that the fuel-shutoff valve is closed before transporting or storing the machine to prevent fuel leakage. Engage the parking brake before transporting.
Driving the Machine The drive wheels turn independently, powered by hydraulic motors on each axle. You can turn 1 side in reverse while you turn the other forward, causing the machine to spin rather than turn. This greatly improves the machine maneuverability but may require some time for you to adapt to how it moves. The throttle control regulates the engine speed as measured in rpm (revolutions per minute). Place the throttle control in the FAST position for best performance.
Using the Side Discharge 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. Contact with rotating mower blade(s) and thrown debris will cause injury or death. • Never remove the grass deflector from the mower deck because the grass deflector routes material down toward the turf.
4. Select a hole in the height-of-cut bracket corresponding to the height-of-cut desired, and insert the pin (Figure 33). Adjusting the Anti-Scalp Rollers 5. Push on the deck lift, pull up on the transport lock knob, and slowly lower the mower deck. Whenever you change the height of cut, adjust the height of the anti-scalp rollers. Note: Adjust the anti-scalp rollers so that the rollers do not touch the ground in normal, flat mowing areas. 1.
Operating Tips drop onto your lawn. To avoid this, move onto a previously cut area with the blades engaged or you can disengage the mower deck while moving forward. Using the Fast Throttle Setting For best mowing and maximum air circulation, operate the engine at the FAST 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 deck in uncut grass.
Using the Drive-Wheel Release Valves Using the Fuel-Shutoff Valve Close the fuel-shutoff valve for transport, maintenance, and storage (Figure 35). WARNING Hands may become entangled in the rotating drive components below the engine deck, which could result in serious injury. Ensure that the fuel-shutoff valve is open when starting the engine. Shut off the engine, remove the key, and allow all moving parts to stop before accessing the drive-wheel release valves.
