This manual uses two other words to highlight information.

Important calls attention to special mechanical

information and Note: emphasizes general information worthy of special attention.

General Operation

• Read, understand, and follow all instructions in the operator’s manual and on the machine before starting.

• Do not place hands or feet near rotating parts or under the machine. Keep clear of the discharge opening at all times.

• Allow only responsible adults who are familiar with the instructions to operate the machine.

• Clear the area of objects such as rocks, toys, wire, etc., which could be picked up and thrown by the blade.

• Be sure the area is clear of other people before mowing. Stop the machine if anyone enters the area.

• Never carry passengers.

• Do not mow in reverse. Always look down and behind

before and while backing up.

• Be aware of the mower discharge direction and do not point it at anyone. Avoid discharging material against a wall or obstruction. Material may ricochet back toward the operator. Stop the blade(s) when crossing gravel surfaces.

• Do not operate the mower without either the entire grass catcher or the guard in place.

• Be alert, slow down and use caution when making turns. Look behind and to the side before changing directions.

• Never leave a running machine unattended. Always turn off blades, set parking brake, stop engine, and remove key before dismounting.

Safety

This machine meets or exceeds the B71.1–2003 specifications of the American National Standards Institute, in effect at the time of production. However, improper use or maintenance by the operator or owner can result in injury. To reduce the potential for injury, comply with these safety instructions and always pay attention to the safety alert CAUTION, WARNING, or DANGER—“personal safety instruction.” Failure to comply with the instruction may result in personal injury or death.

symbol, which means

• Turn off blades when not mowing. Stop the engine and what for all parts to come to a complete stop before cleaning the machine, removing the grass catcher or unclogging the discharge chute.

• Operate the machine only in daylight or good artificial light.

• Do not operate the machine while under the influence of alcohol or drugs.

• Watch for traffic when operating near or crossing roadways.

• Use extra care when loading or unloading the machine into a trailer or truck.

Page 4

• Always wear safety goggles or safety glasses with side shields when operating mower.

• Data indicates that operators, age 60 years and above, are involved in a large percentage of riding mower–related injuries. These operators should evaluate their ability to operate the riding mower safely enough to protect themselves and others from serious

injury

• Always follow the recommendations for wheel weights or counterweights.

Slope Operation

• Do not mow slopes greater than 15 degrees.

• Watch for ditches, holes, rocks, dips, and rises that

change the operating angle, as rough terrain could overturn the machine.

• Choose a low ground speed so you will not have to stop while operating on a slope.

• Do not mow slopes when grass is wet. Slippery conditions reduce traction and could cause sliding and loss of control.

• Always keep the machine in gear when going down slopes. Do not shift to neutral and coast downhill.

• Reduce speed and use extreme caution on slopes.

• Do not make sudden turns or rapid speed changes.

• Use a walk behind mower and/or a hand trimmer near

drop–offs, ditches, steep banks or water.

• Remove or mark obstacles such as rocks, tree limbs, etc. from the mowing area. Tall grass can hide obstacles.

• Avoid sudden starts when mowing uphill because the mower may tip backwards.

• Be aware that loss of traction may occur going downhill. Weight transfer to the front wheels may cause drive wheels to slip and cause loss of braking and steering.

• Always avoid sudden starting or stopping on a slope. If tires lose traction, disengage the blades and proceed slowly off the slope.

• Use extreme care with grass catchers or other attachments. These can change the stability of the machine and cause loss of control.

• Do not try to stabilize the machine by putting your foot on the ground.

• Do not mow near drop–offs, ditches, steep banks or water. Wheels dropping over edges can cause rollovers, which may result in serious injury, death or drowning.

Children

Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the machine and the mowing activity. Never assume that children will remain where you last saw them.

• Keep children out of the mowing area and under the watchful care of another responsible adult.

• Be alert and turn the machine off if children enter the area.

• Before and while backing or changing direction, look behind, down, and side–to–side for small children.

• Never carry children, even with the blades off. They may fall off and be seriously injured or interfere with safe machine operation.

• Children who have been given rides in the past may suddenly appear in the mowing area for another ride and be run over or backed over by the mower.

• Never allow children to operate the machine.

• Use extra care when approaching blind corners, shrubs,

trees, the end of a fence or other objects that may obscure vision.

Service

• Use extra care when handling gasoline and other fuels. They are flammable and vapors are explosive.

• Extinguish all cigarettes, cigars, pipes and other

sources of ignition.

• Use only an approved container.

• Never remove the gas cap or add fuel when the

engine is running. Allow the engine to cool before refueling. Do not smoke.

• Never refuel the machine indoors.

• Never store the machine or fuel container inside

where there is an open flame, such as near a water heater or furnace.

• Never fill containers inside a vehicle or on a truck or

trailer with a plastic liner. Always place containers on the ground away from your vehicle before filling.

• Remove gas-powered equipment from the truck or

trailer and refuel it on the ground. If this is not possible, then refuel such equipment with a portable container, rather than from a gasoline dispenser nozzle.

• Keep the nozzle in contact with the rim of the fuel

tank or container opening at all times until the fueling is complete. Do not use a nozzle lock-open device.

Page 5

• If fuel is spilled on clothing, change clothing immediately.

Gasoline and Oil

Recommended Gasoline

Use UNLEADED Regular Gasoline suitable for automotive use (87 pump octane minimum). Leaded regular gasoline may be used if unleaded regular is not available.

Important Never use methanol, gasoline containing

methanol, or gasohol containing more than 10% ethanol because the fuel system could be damaged. Do not mix oil with gasoline.

Danger

In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property.

• Fill the fuel tank outdoors, in an open area, when the engine is cold. Wipe up any gasoline that spills.

• Never fill the fuel tank inside an enclosed trailer.

• Do not fill the fuel tank completely full. Add

gasoline to the fuel tank until the level is 1/4 to 1/2 inch (6 to 13 mm) below the bottom of the filler neck. This empty space in the tank allows gasoline to expand.

• Never smoke when handling gasoline, and stay away from an open flame or where gasoline fumes may be ignited by a spark.

• Store gasoline in an approved container and keep it out of the reach of children. Never buy more than a 30-day supply of gasoline.

• Always place gasoline containers on the ground away from your vehicle before filling.

• Do not fill gasoline containers inside a vehicle or on a truck or trailer bed because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge.

• When practical, remove gas–powered equipment from the truck or trailer and refuel the equipment with its wheels on the ground.

• If this is not possible, then refuel such equipment on a truck or trailer from a portable container, rather than from a gasoline dispenser nozzle.

• If a gasoline dispenser nozzle must be used, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.

Warning

Gasoline is harmful or fatal if swallowed. Long–term exposure to vapors can cause serious injury and illness.

• Avoid prolonged breathing of vapors.

• Keep face away from nozzle and gas tank or

conditioner opening.

• Keep gas away from eyes and skin.

Using Stabilizer/Conditioner

Use a fuel stabilizer/conditioner in the machine to provide the following benefits:

• Keeps gasoline fresh during storage of 90 days or less. For longer storage it is recommended that the fuel tank be drained.

• 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 gas stabilizer/conditioner to the gas.

Note: A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times.

Filling the Fuel Tank

1. Shut the engine off and set the parking brake.

2. Clean around the fuel tank cap and remove the cap. Add

unleaded regular gasoline to the fuel tank until the level is 1/4 to 1/2 inch (6 to 13 mm) below the bottom of the filler neck. This space in the tank allows gasoline to expand. Do not fill the fuel tank completely full.

3. Install the fuel tank cap securely. Wipe up any gasoline that may have spilled.

Checking the Engine Oil Level

Before you start the engine and use the machine, check the oil level in the engine crankcase; refer to Checking the Oil Level, page 20.

Page 12

Operation

Note: Determine the left and right sides of the machine from the normal operating position.

Think Safety First

Controls

Become familiar with all of the controls (Fig. 3 and 4) before you start the engine and operate the machine.

Please carefully read all of the safety instructions and decals in the safety section. Knowing this information could help you, your family, pets or bystanders avoid injury.

Danger

Mowing on wet grass or steep slopes can cause sliding and loss of control.

Wheels dropping over edges can cause rollovers, which may result in serious injury, death or drowning.

To avoid loss of control and possibility of rollover:

• Do not mow near drop–offs or near water.

• Do not mow slopes greater than 15 degrees.

• Reduce speed and use extreme caution on slopes.

• Avoid sudden turns or rapid speed changes.

2. To install the hood, put the hooks into the slots and slide forward (Fig. 16).

Danger

Without the grass deflector, discharge cover, or 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 discharge area or mower

blades unless you move the PTO to Off and rotate the ignition key to Off. Also remove the key and pull the wire off the spark plug(s).

Tips for Mowing Grass

3. Tighten the knobs in the engine hood (Fig. 15).

Figure 16

1. Engine hood 2. Hook

Side Discharge

The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf.

m–6479

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 by uncut grass. Always try to have one side of the mower free from uncut grass, which allows air to be drawn into the mower.

Cutting a Lawn for the First Time

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 six inches tall, you may want to cut the lawn twice to ensure an acceptable quality of cut.

Cut 1/3 of the Grass Blade

It is best to cut only about 1/3 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.

Mowing Direction

Alternate mowing direction to keep the grass standing straight. This also helps disperse clippings which enhances decomposition and fertilization.

Page 18

Mow at Correct Intervals

Normally, mow every four days. But remember, grass grows at different rates at different times. So to maintain the same cutting height, which is a good practice, 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 two days later at a lower height setting.

Cutting Speed

To improve cut quality, use a slower ground speed.

Avoid Cutting Too Low

If the cutting width of the mower is wider than the mower you previously used, raise the cutting height to ensure that uneven turf is not cut too short.

Long Grass

If the grass is ever allowed to grow slightly longer than normal, or if it contains a high degree of moisture, raise the cutting height higher than usual and cut the grass at this setting. Then cut the grass again using the lower, normal setting.

When Stopping

If the machine’s forward motion must be stopped 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.

Keep the Underside of the Mower Clean

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.

Blade Maintenance

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 cutter blades daily 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.

Servicing the Cutting Blades

Maintain sharp blades throughout the cutting season because sharp blades cut 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 cutter blades daily 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. For convenient sharpening and replacement, you may want to keep extra blades on hand.

Warning

Checking the Spark Plug

1. Look at the center of the spark plug (Fig. 24). If you see light brown or gray on the insulator, the engine is operating properly. A black coating on the insulator usually means the air cleaner is dirty.

Important Never clean the spark plug. Always replace

the spark plug when it has a black coating, worn electrodes, an oily film, or cracks.

2. Check the gap between the center and side electrodes (Fig. 24). Bend the side electrode (Fig. 24) if the gap is not correct.

blades at the same position as in step 1. The difference between the dimensions obtained in steps 1 and 2 must not exceed 1/8 inch (3 mm). If this dimension exceeds 1/8 inch (3 mm), the blade is bent and must be replaced. Refer to Removing the Blades, and Installing the Blades on page 24.

Warning

A blade that is bent or damaged could break apart and could seriously injure or kill you or bystanders.

• Always replace bent or damaged blade with a new blade.

• Never file or create sharp notches in the edges or surfaces of blade.

Removing the Blades

Sharpening the Blades

1. Use a file to sharpen the cutting edge at both ends of the blade (Fig. 28). Maintain the original angle. The blade retains its balance if the same amount of material is removed from both cutting edges.

m–1854

Figure 28

1. Sharpen at original angle

2. Check the balance of the blade by putting it on a blade balancer (Fig. 29). If the blade stays in a horizontal position, the blade is balanced and can be used. If the blade is not balanced, file some metal off the end of the sail area only (Fig. 27). Repeat this procedure until the blade is balanced.

Figure 29

1. Blade 2. Balancer

m–1855

The blades must be replaced if a solid object is hit, if the blade is out of balance, or the blade is bent. To ensure optimum performance and continued safety conformance of the machine, use genuine Toro replacement blades. Replacement blades made by other manufacturers may result in non-conformance with safety standards.
