Safety
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 symbol, which means CAUTION, WARNING, or
DANGER-"personal safety instruction." Failure to comply with the instruction may result in personal injury or death.
Safe Operating Practices
This product is capable of amputating hands and feet and throwing objects. Always follow all safety instructions to avoid serious injury or death.
The following safety instructions are based on ANSI standard B71.1-2003. Safety information in addition to the instructions found in the ANSI standard below can be found in Toro Riding Mower Safety at the end of this section.
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 unless absolutely necessary.
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 machine without deflector, discharge cover or entire grass collection system in place and working.
• 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.
• Turn off blades when not mowing. Stop the engine, wait for all parts to come to a complete stop and remove the key 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.
• Always wear eye protection when operating the mower.
• Data indicates that operators, age 60 years and above, are involved in a large percentage of riding mower-related injuries. 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 any application of counterweights.
• Lightning can cause severe injury or death. If lightning is seen or thunder is heard in the area, do not operate the machine; seek shelter.
Slope Operation
Slopes are a major factor related to loss of control and tip-over accidents, which can result in severe injury or death. Operation on all slopes requires extra caution. If you cannot back up the slope or if you feel uneasy on it, do not mow it.
• 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 drive wheels engaged when going down slopes.
• Reduce speed and use extreme caution on slopes.
4
• Do not make sudden turns or rapid speed changes.
• 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, stop the machine, 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.
• Use a walk behind mower and/or a hand trimmer near drop-offs, ditches, steep banks or water.
Using the Rollover Protection System
(ROPS)
• Keep the roll bar in the fully raised and locked position and use the seat belt when operating the machine.
• Be certain that the seat belt can be released quickly in the event of an emergency.
• Be aware there is no rollover protection when the roll bar is down.
• Check the area to be mowed and never fold the
ROPS in areas where there are slopes, drop offs or water.
• Lower the rollbar only when absolutely necessary.
Do not wear the seat belt with the roll bar folded down.
• Check carefully for overhead clearances (i.e.
branches, doorways, electrical wires) before driving under any objects and do not contact them.
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, not the operator.
• 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.
Towing
A hitch kit is available for this machine and can be obtained by contacting an Authorized Toro Dealer.
Do not tow without first installing this manufacturer approved hitch. The following guidelines apply when towing with the approved hitch kit installed.
• Tow only with a machine that has a hitch designed for towing. Do not attach towed equipment except at the hitch point.
• Follow the manufacturer's recommendation for weight limits for towed equipment and towing on slopes.
• Never allow children or others in or on towed equipment.
• On slopes, the weight of the towed equipment may cause loss of traction and loss of control.
• Travel slowly and allow extra distance to stop.
Service
Safe Handling of Gasoline:
To avoid personal injury or property damage, use extra care when handling gasoline and other fuels. They are flammable and the 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.
5
• 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.
• If fuel is spilled on clothing, change clothing immediately.
• Never overfill the fuel tank. Replace gas cap and tighten securely.
General Service:
• Never operate a machine inside a closed area. Engine exhaust contains carbon monoxide, which is an odorless, deadly poison that can kill you.
• Keep nuts and bolts tight, especially the blade attachment bolts. Keep equipment in good condition.
• Never tamper with safety devices. Check their proper operation regularly.
• Keep the machine free of grass, leaves, or other debris build-up. Clean up oil or fuel spillage fuel soaked debris. Allow the machine to cool before storing.
• Stop and inspect the equipment if you strike an object. Repair, if necessary, before restarting.
• Never make any adjustments or repairs with the engine running.
• Grass catcher components are subject to wear, damage and deterioration, which could expose moving parts or allow objects to be thrown.
Frequently check components and replace with manufacturers' recommended parts, when necessary.
• Mower blades are sharp and can cut. Wrap the blade(s) or wear gloves, and use extra caution when servicing them.
• Check for proper brake operation frequently. Adjust and service as required.
• Maintain or replace safety and instruction decals as necessary.
• Use only genuine Toro replacement parts to ensure that original standards are maintained.
Toro Riding Mower Safety
The following list contains safety information specific to
Toro products or other safety information that you must know that may not be included in the ANSI standards.
• Stop the engine, move the motion control levers to neutral and outward to the park position, disengage the blade control switch, remove key before and disconnect spark plug wire(s) performing any service, repairs, maintenance or adjustments.
• Keep hands, feet, hair, and loose clothing away from attachment discharge area, underside of mower and any moving parts while engine is running.
• Do not touch equipment or attachment parts which may be hot from operation. Allow to cool before attempting to maintain, adjust or service.
• Battery acid is poisonous and can cause burns. Avoid contact with skin, eyes, and clothing. Protect your face, eyes, and clothing when working with a battery.
• Battery gases can explode. Keep cigarettes, sparks and flames away from battery.
• Use only Toro approved attachments. Warranty may be voided if used with unapproved attachments.

Note: Determine the left and right sides of the machine from the normal operating position.
Think Safety First
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.
A loss of traction is a loss of steering control.
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.
• When mowing slopes, gradually work from lower to higher areas on the incline.
• Avoid sudden turns or rapid speed changes.
• Turn up, into an incline when changing directions on slopes. Turning down the slope reduces traction.
• Attachments change the handling characteristics of the machine. Use extra caution when using attachments with the machine.

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.
• Do not operate without entire exhaust system in place and in proper working condition.
DANGER
In certain conditions during fueling, static electricity can be released causing a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property.
• 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.
19
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.
Fuel Gauge
Use the fuel window below the operator to verify the
level of gasoline before filling the tank (Figure 12).

Filling the Fuel Tank
Make sure the engine is shut off and the motion controls are in the park position.
Important: Do Not overfill fuel tank. Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows the fuel to expand.
Overfilling may result in fuel leakage or damage to the engine or emission system.
1. Clean around the fuel tank cap and remove the cap.
Note: You can use the fuel window below the operating position verify the presence of gasoline
before filling the tank (Figure 12).
2.
Slowly add regular, unleaded gasoline until the fuel
reaches the base of the filler neck Figure 13.
3. Install the fuel tank cap securely and tighten until it
“clicks”. Wipe up any gasoline that may have spilled.

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 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 off and remove the key.
• Make sure the grass deflector is in the down position.
Operating Tips
Fast Throttle Setting
For best mowing and maximum air circulation, operate the engine at the fast throttle 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 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.
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 in certain conditions.
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.

Maintenance
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
A worn or damaged blade can break, and a piece of the blade could be thrown into the operator's or bystander's area, resulting in serious personal injury or death.
• Inspect the blade periodically for wear or damage.
• Replace a worn or damaged blade.
Before Inspecting or Servicing the
Blades
Park the machine on a level surface, disengage the blade control switch (PTO), and set the parking brake. Turn the ignition key to Off. Remove the key.
Inspecting the Blades
Service Interval: Before each use or daily
1. Inspect the cutting edges (Figure 54). If the edges
are not sharp or have nicks, remove and sharpen the blades. Refer to Sharpening the Blades.

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.
A. If the difference between A and B is greater than 1/8 inch (3mm) 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 one and the dimension obtained continues to exceed
1/8 inch (3mm), the blade spindle could be bent.
Contact an Authorized Toro Dealer for service.
B. If the variance is within constraints, move to the next blade..
Repeat this procedure on each blade.
Removing the Blades
Blades must be replaced if a solid object is hit, if the blade is out of balance or 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.

Sharpening the Blades
WARNING
When sharpening blade, pieces of blade could be thrown and cause serious injury.
Wear proper eye protection when sharpening blade.
1. Use a file to sharpen the cutting edge at both ends
of the blade (Figure 60). Maintain the original angle.
The blade retains its balance if the same amount of material is removed from both cutting edges.
Installing the Blades
1. Install the blade onto the spindle shaft (Figure 59).
Important: The curved part (sail of the blade) of the blade must be pointing upward toward the inside of the mower to ensure proper cutting.
2. Install the spring disk and blade bolt (rotating it clockwise). The spring disk cone must be installed
toward the bolt head (Figure 59). Torque the blade
bolt to 100-110 ft-lb (135-150 N-m).

There is no other express warranty except for special emission system coverage and engine warranty coverage on some products. This express warranty does not cover the following:
•
Cost of regular maintenance service or parts, such as filters, fuel, lubricants, oil changes, spark plugs, air filters, blade sharpening/worn blade on mowers, cable/linkage adjustments, or brake and clutch adjustments
•
Components failing due to normal wear

Any product or part which has been altered or misused and requires replacement or repair due to accidents or lack of proper maintenance

1 Some engines used on Toro Products are warranted by the engine manufacturer.
2 Residential use means use of the product on the same lot as your home. Use at more than one location is considered commercial use and the commercial use warranty would apply.
3 Whichever occurs first.
4 Lifetime Frame Warranty - If the main frame, consisting of the parts welded together to form the tractor structure that other components such as the engine are secured to, cracks or breaks in normal use, it will be repaired or replaced, at Toro's option, under warranty at no cost for parts and labor. Frame failure due to misuse or abuse and failure or repair required due to rust or corrosion are not covered.
This warranty includes the cost of parts and labor, but you must pay transportation costs.
Warranty may be denied if the hour meter is disconnected, altered, or shows signs of being tampered with.
Owner Responsibilities
You must maintain your Toro Product by following the maintenance procedures described in the Operator's Manual . Such routine maintenance, whether performed by a dealer or by you, is at your expense.
General Conditions
All repairs covered by these warranties must be performed by an
Authorized Toro Service Dealer using Toro approved replacement parts.
Neither The Toro Company nor Toro Warranty Company is liable for indirect, incidental or consequential damages in connection with the use of the Toro Products covered by this warranty, including any cost or expense of providing substitute equipment or service during reasonable periods of malfunction or non-use pending completion of repairs under this warranty.
All implied warranties of merchantability (that the product is fit for ordinary use) and fitness for use (that the product is fit for a particular purpose) are limited to the duration of the express warranty.
Some states do not allow exclusions of incidental or consequential damages, or limitations on how long an implied warranty lasts, so the above exclusions and limitations may not apply to you.
This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.
Countries Other than the United States or Canada
Customers who have purchased Toro products outside the United States or Canada should contact their Toro Distributor (Dealer) to obtain guarantee policies for your country, province, or state. If for any reason you are dissatisfied with your Distributor's service or have difficulty obtaining guarantee information, contact the Toro importer. If all other remedies fail, you may contact us at Toro Warranty Company.
