Use only an approved fuel container.
Do not remove the fuel cap or add fuel to the fuel tank while the engine is running or while hot.
Do not refuel the machine indoors.
Do not store the machine or fuel container where there is an open flame, spark, or pilot light, such as on a water heater or on other appliances.
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.
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.
Do not operate the machine without the entire exhaust system in place and in proper working condition.
Keep the fuel-dispenser nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock-open device.
If you spill fuel on your clothing, change your clothing immediately. Wipe up any fuel that spills.
Never overfill the fuel tank. Replace the fuel cap and tighten it securely.
Store fuel in an approved container and keep it out of the reach of children. Never buy more than a 30-day supply of fuel.
Do not fill the fuel tank completely full. Add fuel to the fuel tank until the level is 6 to 13 mm (1/4 to 1/2 inch) below the bottom of the filler neck. This empty space in the tank allows fuel to expand.
Avoid prolonged breathing of vapors.
Keep your face away from the nozzle and gas tank opening.
Avoid contact with skin; wash off spills with soap and water.
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. Never use gasoline that contains more than 10% ethanol by volume, such as E15 (contains 15% ethanol), E20 (contains 20% ethanol), or E85 (contains up to 85% ethanol). Using unapproved gasoline may cause performance problems and/or engine damage which may not be covered under warranty.
Do not use gasoline containing methanol.
Do not store fuel either in the fuel tank or fuel containers over the winter unless you use a fuel stabilizer.
Do not add oil to gasoline.
Use a fuel stabilizer/conditioner in the machine to provide the following benefits:
Keeps fuel fresh during storage of 90 days or less (drain the fuel tank when storing the machine for more than 90 days)
Cleans the engine while it runs
Eliminates gum-like varnish buildup in the fuel system, which causes hard starting
Important: Do not use fuel additives containing methanol or ethanol.
Add the correct amount of fuel stabilizer/conditioner to the fuel.
Note: A fuel stabilizer/conditioner is most effective when mixed with fresh fuel. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times.
Park the machine on level ground.
Shut off the engine and engage the parking brake.
Clean around the fuel-tank cap.
Fill the fuel tank to the bottom of the filler neck (Figure 8).
Note: Do not fill the fuel tank completely full. The empty space in the tank allows the gasoline to expand.
Before you start the engine and use the machine, check the oil level in the engine crankcase; refer to Checking the Engine-Oil Level.
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.
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.
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.
Check carefully for overhead clearances (i.e., branches, doorways, electrical wires) before driving under any objects and do not contact them.
Important: Lower the roll bar only when absolutely necessary.
To lower the roll bar, apply forward pressure to the upper part of the roll bar.
Pull both knobs out and rotate them 90 degrees so they are not engaged (Figure 9).
Lower the roll bar to the down position (Figure 9).
To raise the roll bar, raise the roll bar to the operating position and rotate the knobs until they move partially into the grooves (Figure 9).
Raise the roll bar to the full upright position while pushing on the upper roll bar so that the pins snap into position when the holes align with the pins (Figure 9).
Important: Always use the seat belt with the roll bar in the raised position.
Push on the roll bar and ensure that both pins are engaged.
Please read all safety instructions and symbols in the safety section. Knowing this information could help you or bystanders avoid injury.
Operating the machine on wet grass or steep slopes can cause sliding and loss of control.
Do not operate on slopes greater than 15 degrees.
Reduce speed and use extreme caution on slopes.
Do not operate the machine near water.
Wheels dropping over edges can cause rollovers, which may result in serious injury, death, or drowning.
Do not operate the machine near drop-offs.
Operating the machine while the roll bar is down may lead to serious injury or death in the event of a rollover.
Always keep the roll bar in the fully raised and locked position and use the seat belt.
This machine produces sound levels in excess of 85 dBA at the operator’s ear and can cause hearing loss through extended periods of exposure.
Wear hearing protection when operating this machine.
Use protective equipment for your eyes, ears, hands, feet, and head.
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.
The safety-interlock system is designed to prevent the engine from starting unless:
The parking brake is engaged.
The blade-control switch (PTO) is disengaged.
The motion-control levers are in the NEUTRAL-LOCK position.
The safety-interlock system is also designed to shut off 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. When the component is in the correct position, a triangle lights up in the corresponding square.

Children or bystanders may be injured if they move or attempt to operate the machine while it is unattended.
Always remove the ignition key and engage the parking brake when leaving the machine unattended, even if just for a few minutes.
Move the throttle to the FAST position and turn the switch to the OFF position.
Important: Make sure that the fuel-shutoff valve is closed before transporting or storing the machine, as fuel leakage may occur. Engage the parking brake before transporting. Make sure that you remove the key as the fuel pump may run and cause the battery to lose charge.
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 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. Always operate in the full throttle position when mowing.
Machine can spin very rapidly. Operator may lose control of machine and cause personal injury or damage to machine.
Use caution when making turns.
Slow the machine down before making sharp turns.
Note: The engine stops when you move the traction-control with the parking brake engaged.

Children or bystanders may be injured if they move or attempt to operate the machine while it is unattended.
Always remove the ignition key and engage the parking brake when leaving the machine unattended, even if just for a few minutes.
The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf.
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 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.
Never try to clear the discharge area or mower blades unless you move the blade-control switch (PTO) to the OFF position, rotate the ignition key to the OFF position, and remove the key.
Make sure that the grass deflector is in the down position.
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 in uncut grass. Always try to have 1 side of the mower free from uncut grass, which allows air to be drawn into the mower.
Cut grass slightly longer than normal to ensure that the cutting height of the mower does not scalp any uneven ground. However, the cutting height used in the past is generally the best one to use. When cutting grass longer than 15 cm (6 inches) tall, you may want to cut the lawn twice to ensure an acceptable quality of cut.
It is best to cut only about a third of the grass blade. Cutting more than that is not recommended unless grass is sparse, or it is late fall when grass grows more slowly.
Alternate the mowing direction to keep the grass standing straight. This also helps disperse clippings which enhances decomposition and fertilization.
Grass grows at different rates at different times of the year. To maintain the same cutting height, mow more often in early spring. As the grass growth rate slows in mid summer, mow less frequently. If you cannot mow for an extended period, first mow at a high cutting height, then mow again 2 days later at a lower height setting.
To improve cut quality, use a slower ground speed in certain conditions.
When mowing uneven turf, raise the cutting height to avoid scalping the turf.
If you must stop the forward motion of the machine 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 or you can disengage the mower deck while moving forward.
Clean clippings and dirt from the underside of the mower after each use. If grass and dirt build up inside the mower, cutting quality will eventually become unsatisfactory.
Maintain a sharp blade throughout the cutting season because a sharp blade cuts cleanly without tearing or shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease. Check the mower blades after each use 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.
Clean grass and debris from the cutting units, mufflers, and engine compartment to help prevent fires. Clean up oil or fuel spills.
Shut off the fuel before storing or transporting the machine.
Disengage the drive to the attachment whenever you are transporting or not using the machine.
Use full-width ramps for loading the machine into a trailer or truck.
Tie the machine down securely using straps, chains, cable, or ropes. Both front and rear straps should be directed down and outward from the machine.
Allow the engine to cool before storing the machine in any enclosure.
Shut off the fuel before storing or transporting the machine.
Never store the machine or fuel container where there is an open flame, spark, or pilot light, such as on a water heater or on other appliances.
The fuel-shutoff valve is located behind the seat.
Close the fuel-shutoff valve for transport, maintenance, and storage.
Ensure that the fuel-shutoff valve is open when starting the engine.
Hands may become entangled in the rotating drive components below the engine deck, which could result in serious injury.
Shut off the engine, remove the key, and allow all moving parts to stop before accessing the drive-wheel-release valves.
The engine and hydraulic-drive units can become very hot. Touching a hot engine or hydraulic-drive units can cause severe burns.
Allow the engine and hydraulic-drive units to cool completely before accessing the drive-wheel-release valves.
The drive-wheel-release valves are located on the left and right sides underneath the engine deck.
Disengage the blade-control switch (PTO), turn the ignition key to off, move the levers to the NEUTRAL-LOCK position, apply the parking brake, and remove the key.
Locate the bypass levers behind the seat, down on the left and right side of the frame.
To push the machine, move both bypass knobs rearward and lock them into place (Figure 34).
Disengage the parking brake before pushing the machine.
To run the machine, move the bypass knobs to the FORWARD position and lock them into place (Figure 34).
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.
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.
Do not drive the machine on a public street or roadway.
To transport the machine:
If you are using a trailer, connect it to the towing vehicle and connect the safety chains.
If applicable, connect the trailer brakes.
Load the machine onto the trailer or truck.
Shut off the engine, remove the key, set the brake, and close the fuel valve.
Use the metal tie-down loops on the machine to securely fasten the it to the trailer or truck with straps, chains, cable, or ropes (Figure 35).
Use extreme caution when loading or unloading machines onto a trailer or a truck. Use a full-width ramp that is wider than the machine for this procedure. Back up the ramp and drive forward down the ramp (Figure 36).
Important: Do not use narrow individual ramps for each side of the machine.
Loading a machine onto a trailer or truck increases the possibility of tip-over and could cause serious injury or death (Figure 37).
Use extreme caution when operating a machine on a ramp.
Use only a full-width ramp; do not use individual ramps for each side of the machine.
Do not exceed a 15-degree angle between the ramp and the ground or between the ramp and the trailer or truck.
Ensure that the length of ramp is at least 4 times as long as the height of the trailer or truck bed to the ground. This ensures that the ramp angle does not exceed 15 degrees on flat ground.
Back up ramps and drive forward down ramps.
Avoid sudden acceleration or deceleration while driving the machine on a ramp as this could cause a loss of control or a tip-over situation.
