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 fuel 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 a level surface.
Engage the parking brake.
Shut off the engine and remove the key.
Clean around the fuel-tank cap.
Fill the fuel tank to the bottom of the filler neck (Figure 9).
Note: Do not fill the fuel tank completely full. The empty space in the tank allows the fuel 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.
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.

While the engine is running, move the motion-control levers to the center, unlocked position, engage the blade-control switch, and rise slightly from the seat; the engine should shut off.
The seat can move forward and backward. Position the seat where you have the best control of the machine and are most comfortable (Figure 12).
You can adjust the motion-control levers higher or lower for maximum comfort (Figure 13).
You can adjust the motion-control levers forward or rearward for your comfort.
Loosen the upper bolt holding the control lever to the control-arm shaft.
Loosen the lower bolt just enough to pivot the control lever forward or rearward (Figure 13).
Tighten both bolts to secure the control lever in the new position.
Repeat the adjustment for the other control lever.
The owner/operator can prevent and is responsible for accidents that may cause personal injury or property damage.
Wear appropriate clothing, including eye protection; slip-resistant, substantial footwear; and hearing protection. Tie back long hair and do not wear jewelry.
Do not operate the machine while ill, tired, or under the influence of alcohol or drugs.
Never carry passengers on the machine and keep bystanders and pets away from the machine during operation.
Operate the machine only in good visibility to avoid holes or hidden hazards.
Avoid mowing on wet grass. Reduced traction could cause the machine to slide.
Ensure that all drives are in neutral, the parking brake is engaged, and you are in the operating position before you start the engine.
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, trees, or other objects that may obscure your vision.
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.
Stop the blades whenever you are not mowing.
Stop the machine and inspect the blades after striking an object or if there is an abnormal vibration in the machine. Make all necessary repairs before resuming operation.
Slow down and use caution when making turns and crossing roads and sidewalks with the machine. Always yield the right-of-way.
Disengage the drive to the cutting unit and shut off the engine before adjusting the height of cut (unless you can adjust it from the operating position).
Never run an engine in an area where exhaust gases are enclosed.
Never leave a running machine unattended.
Before leaving the operating position (including to empty the catchers or to unclog the chute), do the following:
Park the machine on a level surface.
Disengage the power take-off and lower the attachments.
Engage the parking brake.
Shut off the engine and remove the key.
Wait for all moving parts to stop.
Do not operate the machine when there is the risk of lightning.
Do not use the machine as a towing vehicle.
Do not change the governor speed or overspeed the engine.
Use accessories and attachments approved by Toro only.
Establish your own procedures and rules for operating on slopes. These procedures must include surveying the site to determine which slopes are safe for machine operation. Always use common sense and good judgment when performing this survey.
Slopes are a major factor related to loss-of-control and tip-over accidents, which can result in severe injury or death. Operating the machine on any slope requires extra caution.
Operate the machine at a lower speed when you are on a slope.
If you feel uneasy operating the machine on a slope, do not do it.
Watch for holes, ruts, bumps, rocks, or other hidden objects. Uneven terrain could overturn the machine. Tall grass can hide obstacles.
Choose a low ground speed so you will not have to stop or shift while on a slope.
A rollover can occur before the tires lose traction.
Avoid operating the machine on wet grass. Tires may lose traction; regardless if the brakes are available and functioning.
Avoid starting, stopping, or turning the machine on a slope.
Keep all movement on slopes slow and gradual. Do not suddenly change the speed or direction of the machine.
Do not operate the machine near drop-offs, ditches, embankments, or bodies of water. The machine could suddenly roll over if a wheel goes over the edge or the edge caves in. Establish a safety area between the machine and any hazard (2 machine widths).
The blade-control switch (PTO) starts and stops the mower blades and any powered attachments.
You can move the throttle control between the FAST and SLOW positions (Figure 17).
Always use the FAST position when turning on the mower deck with the blade-control switch (PTO).
Use the choke to start a cold engine.
If the engine is cold, use the choke to start the engine.
Pull up the choke knob to engage the choke before using the ignition switch (Figure 18).
Note: Ensure that you fully engage the choke. You may need to hold the knob up when you use the ignition switch.
Push down the choke to disengage the choke after the engine has started (Figure 18).
Turn the ignition key to the START position (Figure 19).
Note: When the engine starts, release the key.
Important: Do not engage the 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.
Note: You may need multiple attempts to start the engine when you start it the first time after the fuel system has been without fuel completely.
Turn the ignition key to the STOP position to shut off the engine.
Note: A warm or hot engine may not require choking.
Important: Do not engage the starter for more than 5 seconds at a time. Engaging the starter motor for more than 5 seconds can damage the starter motor. If the engine fails to start, wait 10 seconds before operating the engine starter again.
Disengage the blades by moving the blade-control switch to the OFF position (Figure 20).
Move the throttle lever to the FAST position.
Turn the ignition key to the OFF position and remove the key.
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 sometime 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.
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.
Note: Always use caution when backing up and turning.
Move the levers to the center, unlocked position.
To go forward, slowly push the motion-control levers forward (Figure 22).
Move the levers to the center, unlocked position.
To go backward, slowly pull the motion-control levers rearward (Figure 23).
The Smart Speed TM Control-System lever, located below the operating position (Figure 24), gives the operator a choice to drive the machine at 3 ground speed ranges—trim, tow, and mow.
To change speeds, do the following:
Move the motion-control levers to neutral and outward to the PARK position.
Disengage the blade-control switch.
Adjust the lever to the desired position.
The following are only recommendations for use. Adjustments vary by grass type, moisture content, and the height of the grass.

Transporting the machine
To stop the machine, move the motion-control levers to NEUTRAL and outward to the PARK position, disengage the blade-control switch, ensure that the throttle is in the FAST position, and turn the key to OFF. Remove the key from the switch.
Children or bystanders may be injured if they move or attempt to operate the mower while it is unattended.
Always remove the ignition key and move the motion-control levers outward to the PARK position when leaving the machine unattended, even if just for a few minutes.
Note: The transport position is the highest height-of-cut position at 115 mm (4-1/2 inches) as shown in Figure 25.
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.
Disengage the blade-control switch (PTO), move the motion-control levers to the PARK position, and engage the parking brake.
Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.
Adjust the anti-scalp rollers as shown in Figure 26 to match the closest height-of-cut position.
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.
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.
Important: Always push the machine by hand. Do not tow the machine, because damage to the hydraulic drive system may occur.
This machine has an electric-brake mechanism. To push the machine, turn the ignition key to the RUN position. The battery must be charged and functioning to disengage the electric brake.
Park the machine on a level surface and disengage the blade-control switch.
Move the motion-control levers outward to the PARK position, shut off the engine, and wait for all moving parts to stop before leaving the operating position.
Locate the bypass levers on the frame on both sides of the engine.
Move the bypass levers forward through the key hole and down to lock them in place (Figure 27).
Note: Do this for each lever.
Move the motion-control levers inward to the NEUTRAL position and turn the ignition key to the RUN position.
Note: Do not start the machine.
Note: You can now push the machine by hand.
When finished, turn the key to the STOP position to avoid draining the battery charge.
Note: If the machine fails to move, the electric brake may still be engaged. You can release the electric brake if necessary; refer to Releasing the Electric Brake.
Move the bypass levers rearward through the key hole and down to lock them in place as shown in Figure 27.
Note: Do this for each lever.
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.
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.
Tie down the machine near the front caster wheels and the rear bumper (Figure 28).
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 the machine up the ramp and drive it forward down the ramp (Figure 29).
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 30).
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 the machine up the ramp and drive it forward down the ramp.
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.
Note: Determine the left and right sides of the machine from the normal operating position.

Inspect the cutting edges (Figure 49).
If the edges are not sharp or have nicks, remove and sharpen the blade; refer to Sharpening the Blades.
Inspect the blades, especially in the curved area.
If you notice any cracks, wear, or a slot forming in this area, immediately install a new blade (Figure 49).
Note: The machine must be on a level surface for the following procedure.
Raise the mower deck to the highest height-of-cut position.
While wearing thickly padded gloves, or other adequate hand protection, slowly rotate the blade to be measure into a position that allows effective measurement of the distance between the cutting edge and the level surface the machine is on (Figure 50).
Measure from the tip of the blade to the flat surface (Figure 51).
Rotate the same blade 180 degrees so that the opposing cutting edge is now in the same position (Figure 52).
Measure from the tip of the blade to the flat surface (Figure 53).
Note: The variance should be no more than 3 mm (1/8 inch).
If the difference between A and B is greater than 3 mm (1/8 inch), replace the blade with a new blade; refer to Removing the Blades and Installing the Blades.
Note: If a bent blade is replaced with a new blade, and the dimension obtained continues to exceed 3 mm (1/8 inch), the blade spindle could be bent. Contact an Authorized Toro Dealer for service.
If the variance is within constraints, move to the next blade.
Repeat this procedure on each blade.
Replace the blades if they hit a solid object, or if the blade is out of balance or bent.
Hold the blade end using a rag or thickly padded glove.
Remove the blade bolt, curved washer, and blade from the spindle shaft (Figure 54).
Use a file to sharpen the cutting edge at both ends of the blade (Figure 55).
Note: Maintain the original angle.
Note: The blade retains its balance if the same amount of material is removed from both cutting edges.
Check the balance of the blade by putting it on a blade balancer (Figure 56).
Note: If the blade stays in a horizontal position, the blade is balanced and can be used.
Note: If the blade is not balanced, file some metal off the end of the sail area only (Figure 55).
Repeat this procedure until the blade is balanced.
Install the blade onto the spindle shaft (Figure 54).
Important: The curved part of the blade must point upward toward the inside of the mower to ensure proper cutting.
