Before Operation
Before Operation Safety
General Safety
• Never allow children or untrained people to operate or service the machine. Local regulations may restrict the age of the operator. The owner is responsible for training all operators and mechanics.
• Become familiar with the safe operation of the equipment, operator controls, and safety signs.
• Know how to stop the machine and shut off the engine quickly.
• Check that operator-presence controls, safety switches, and shields are attached and functioning properly. Do not operate the machine unless they are functioning properly.
• Before mowing, always inspect the machine to ensure that the blades, blade bolts, and cutting assemblies are in good working condition.
Replace worn or damaged blades and bolts in sets to preserve balance.
• Inspect the area where you will use the machine and remove all objects that the machine could throw.
• Evaluate the terrain to determine the appropriate equipment and any attachments or accessories required to operate the machine properly and safely.
Fuel Safety
• To avoid personal injury or property damage, use extreme care in handling fuel. Fuel vapors are flammable and explosive.
• Extinguish all cigarettes, cigars, pipes, and other sources of ignition.
• 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.
Adding Fuel
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.
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.
15
Using Stabilizer/Conditioner
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.
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.
Clean around the fuel-tank cap.
5.
Fill the fuel tank to the bottom of the filler neck
(
).
Note: Do not fill the fuel tank completely full.
The empty space in the tank allows the fuel to expand.
Figure 7 g027243
Performing Daily
Maintenance
Before starting the machine each day, perform the
Each Use/Daily procedures listed in
.
Breaking in a New Machine
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.
Using the Safety-Interlock
System
WARNING
If the 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.

During Operation
During Operation Safety
General Safety
• The owner/operator can prevent and is responsible for accidents that may cause personal injury or property damage.
• Wear appropriate clothing, including eye protection; long pants; slip-resistant, substantial footwear; and hearing protection. Tie back long hair and do not wear dangling 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.
• Shut off the machine, remove the key, 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:
– Stop the machine on level ground.
– 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 unless it has a hitch installed.
• Do not change the governor speed or overspeed the engine.
• Use only accessories and attachments approved by Toro.
• 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.

Slope Safety
• Slopes are a major factor related to loss of control and rollover accidents, which can result in severe injury or death. The operator is responsible for safe slope operation. Operating the machine on any slope requires extra caution. Before using the machine on a slope, do the following:
– Review and understand the slope instructions in the manual and on the machine.
– Use an angle indicator to determine the approximate slope angle of the area.
– Never operate on slopes greater than 15 degrees.
– Evaluate the site conditions of the day to determine if the slope is safe for machine operation. Use common sense and good judgment when performing this evaluation.
Changes in the terrain, such as moisture, can quickly affect the operation of the machine on a slope.
18
• Identify hazards at the base of the slope. Do not operate the machine near drop-offs, ditches, embankments, water, or other hazards. The machine could suddenly roll over if a wheel goes over the edge or the edge collapses. Keep a safe 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.
• Avoid starting, stopping, or turning the machine on slopes. Avoid making sudden changes in speed or direction; turn slowly and gradually.
• Do not operate a machine under any conditions where traction, steering, or stability is in question.
Be aware that operating the machine on wet grass, across slopes, or downhill may cause the machine to lose traction. Loss of traction to the drive wheels may result in sliding and a loss of braking and steering. The machine can slide even if the drive wheels are stopped.
• Remove or mark obstacles such as ditches, holes, ruts, bumps, rocks, or other hidden hazards. Tall grass can hide obstacles. Uneven terrain could overturn the machine.
• Use extra care while operating with accessories or attachments, such as grass-collection systems.
These can change the stability of the machine and cause a loss of control. Follow directions for counterweights.
• If possible, keep the deck lowered to the ground while operating on slopes. Raising the deck while operating on slopes can cause the machine to become unstable.

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 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 F AST position for best performance. Always operate in the full throttle position when mowing.
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.

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. If the grass deflector is ever damaged, replace it immediately.
• Never put your hands or feet under the mower deck.
• Never try to clear the discharge area or mower blades unless you move the blade-control switch (PTO) to the O FF position, rotate the key switch to the O FF position, and remove the key from the key switch.
• Make sure that the grass deflector is in the down position.

Operating Tips
Using the Fast Throttle Setting
For best mowing and maximum air circulation, operate the engine at the F AST 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. Always try to have 1 side of the mower deck free from uncut grass, which allows air to be drawn into the mower deck.
Cutting a Lawn for the First Time
Cut grass slightly longer than normal to ensure that the cutting height of the mower deck 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.
Cutting a Third of the Grass Blade
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.
Alternating the Mowing Direction
Alternate the mowing direction to keep the grass standing straight. This also helps disperse clippings, which enhances decomposition and fertilization.
Mowing at Correct Intervals
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.
Using a Slower Cutting Speed
To improve cut quality, use a slower ground speed in certain conditions.
Avoiding Cutting Too Low
When mowing uneven turf, raise the cutting height to avoid scalping the turf.
Stopping the Machine
If you must stop the forward motion of the machine while mowing, a clump of grass clippings may
25
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.
After Operation
Keeping the Underside of the
Mower Deck Clean
Clean clippings and dirt from the underside of the mower deck after each use. If grass and dirt build up inside the mower deck, cutting quality will eventually become unsatisfactory.
Maintaining the Blade(s)
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.
After Operation Safety
General Safety
• 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 and remove the key before storing or transporting the machine.
• Disengage the drive to the attachment whenever you are transporting or not using 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.
