Become familiar with all the controls before you start the engine and operate the machine.
The key switch, used to start and shut off the engine, has 3 positions: OFF, RUN, and START. Refer to Starting the Engine.
The throttle controls the engine speed, and it has a continuous-variable setting from the SLOW to FAST position (Figure 6).
Use the choke control to start a cold engine.
The blade-control switch, represented by a power-takeoff (PTO) symbol, engages and disengages power to the mower blades (Figure 6).
Use the motion-control levers to drive the machine forward, reverse, and turn either direction (Figure 5).
Move the motion-control levers outward from the center to the PARK position when exiting the machine (Figure 24). Always position the motion-control levers into the PARK position when you stop the machine or leave it unattended.
The Smart Speed™ Control-System lever, located below the operating position, gives you a choice to drive the machine at 3 speed ranges— trim, tow, and mow (Figure 27).
You can use the fuel window, located on the left side of the machine, to verify the presence of fuel in the tank (Figure 7).
Use the height-of-cut lever to lower and raise the deck from the seated position. Moving the lever up (toward you) raises the deck from the ground and moving the lever down (away from you) lowers the deck toward the ground. Adjust the height-of-cut only while the machine is not moving (Figure 29).
The hour meter records the number of hours when you are in the seat and the key switch is in the ON position (Figure 8).
A selection of Toro approved attachments and accessories is available for use with the machine to enhance and expand its capabilities. Contact your Authorized Service Dealer or authorized Toro distributor or go to www.Toro.com for a list of all approved attachments and accessories.
To ensure optimum performance and continued safety certification of the machine, use only genuine Toro replacement parts and accessories. Replacement parts and accessories made by other manufacturers could be dangerous, and such use could void the product warranty.
Note: Determine the left and right sides of the machine from the normal operating position.
Evaluate the terrain to determine what accessories and attachments are needed to properly and safely perform the job. Only use accessories and attachments approved by Toro.
Inspect the area where the equipment is to be used and remove all rocks, toys, sticks, wires, bones, and other foreign objects. These can be thrown or interfere with the operation of the machine and may cause personal injury to the operator or bystanders.
Wear appropriate personal protective equipment such as safety glasses, substantial slip-resistant footwear, and hearing protection. Tie back long hair and avoid loose clothing and loose jewelry which may get tangled in moving parts.
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.
Check that the operator presence controls, safety switches, and shields are attached and functioning properly. Do Not operate unless they are functioning properly.
Do Not operate the mower when people, especially children, or pets are in the area. Stop the machine and attachment(s) if anyone enters the area.
Do Not operate the machine without the entire grass collection system, discharge deflector, or other safety devices in place and in proper working condition. Grass catcher components are subject to wear, damage and deterioration, which could expose moving parts or allow objects to be thrown. Frequently check for worn or deteriorating components and replace them with the manufacturer’s recommended parts when necessary.
Fill fuel tank on level ground. See Fuel Recommendations in the Specifications section for additional gasoline information.
Do Not add oil to gasoline.
Do Not overfill fuel tank. Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows gasoline to expand. Overfilling may result in fuel leakage or damage to the engine or emission system.
Make sure you understand the controls, their locations, their functions, and their safety requirements.
Refer to the Maintenance section and perform all the necessary inspection and maintenance steps.
Use extreme care when handling fuel.
In certain conditions gasoline is extremely flammable and vapors are explosive.
A fire or explosion from gasoline can burn you, others, and cause property damage.
Fill the fuel tank outdoors on level ground, in an open area, when the engine is cold. Wipe up any gasoline that spills.
Never refill the fuel tank or drain the machine indoors or inside an enclosed trailer.
Do Not fill the fuel tank completely full. Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows gasoline to expand. Overfilling may result in fuel leakage or damage to the engine or emission system.
Never smoke when handling gasoline, and stay away from an open flame or where gasoline fumes may be ignited by spark.
Store gasoline in an approved container and keep it out of the reach of children.
Add fuel before starting the engine. Never remove the cap of the fuel tank or add fuel when engine is running or when the engine is hot.
If fuel is spilled, Do Not attempt to start the engine. Move away from the area of the spill and avoid creating any source of ignition until fuel vapors have dissipated.
Do Not operate without entire exhaust system in place and in proper working condition.
In certain conditions during fueling, static electricity can be released causing a spark which can ignite gasoline vapors. A fire or explosion from gasoline can burn you and others and cause property damage.
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. Do Not use a nozzle lock open device.
Gasoline is harmful or fatal if swallowed. Long-term exposure to vapors has caused cancer in laboratory animals. Failure to use caution may cause serious injury or illness.
Avoid prolonged breathing of vapors.
Keep face away from nozzle and gas tank/container opening.
Keep away from eyes and skin.
Never siphon by mouth.
To help prevent fires:
Keep engine and engine area free from accumulation of grass, leaves, excessive grease or oil, and other debris which can accumulate in these areas.
Clean up oil and fuel spills and remove fuel soaked debris.
Allow the machine to cool before storing the machine in any enclosure. Do Not store near flame or any enclosed area where open pilot lights or heat appliances are present.
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 longer when used as directed by the fuel-stabilizer manufacturer
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 starting the machine each day, perform the Each Use/Daily procedures listed in .
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.
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.
The safety-interlock system is designed to prevent the engine from starting unless:
The blade-control switch (PTO) is disengaged.
The motion-control levers are in the PARK position.
The safety-interlock system also is designed to shut off the engine whenever the control levers are out of the PARK position and you rise from the seat.

Repeat the adjustment for the other control lever.
The operator must use their full attention when operating the machine. Do Not engage in any activity that causes distractions; otherwise, injury or property damage may occur.
Operating engine parts, especially the muffler, become extremely hot. Severe burns can occur on contact and debris, such as leaves, grass, brush, etc. can catch fire.
Allow engine parts, especially the muffler, to cool before touching.
Remove accumulated debris from muffler and engine area.
Engine exhaust contains carbon monoxide, which is an odorless deadly poison that can kill you.
Do Not run engine indoors or in a small confined area where dangerous carbon monoxide fumes can collect.
The owner/user can prevent and is responsible for accidents or injuries occurring to himself or herself, other people or property.
This mower was designed for one operator only. Do not carry passengers and keep all others away from machine during operation.
Do Not operate the machine under the influence of alcohol or drugs.
Operate only in daylight or good artificial light.
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.
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 counter weights if required.
Keep away from holes, ruts, bumps, rocks, and other hidden hazards. Use care when approaching blind corners, shrubs, trees, tall grass or other objects that may hide obstacles or obscure vision. Uneven terrain could overturn the machine or cause the operator to lose their balance or footing.
Be sure all drives are in neutral and parking brake is engaged before starting engine.
Start the engine carefully according to instructions with feet well away from the blades.
Never operate the mower with damaged guards, shields, or covers. Always have safety shields, guards, switches and other devices in place and in proper working condition.
Keep clear of the discharge opening at all times. Never mow with the discharge door raised, removed or altered unless there is a grass collection system or mulch kit in place and working properly.
Keep hands and feet away from moving parts. If possible, Do Not make adjustments with the engine running.
Hands, feet, hair, clothing, or accessories can become entangled in rotating parts. Contact with the rotating parts can cause traumatic amputation or severe lacerations.
Do Not operate the machine without guards, shields, and safety devices in place and working properly.
Keep hands, feet, hair, jewelry, or clothing away from rotating parts.
Never raise the deck with blades running.
Be aware of the mower discharge path and direct discharge away from others. Avoid discharging material against a wall or obstruction as the material may ricochet back toward the operator. Stop the blades, slow down, and use caution when crossing surfaces other than grass and when transporting the mower to and from the area to be mowed.
Be alert, slow down and use caution when making turns. Look behind and to the side before changing directions. Do Not mow in reverse unless absolutely necessary.
Do Not change the engine governor setting or overspeed the engine.
Park the machine on level ground. Stop engine, wait for all moving parts to stop, and remove the spark plug wire(s).
Before checking, cleaning or working on the mower.
After striking a foreign object or abnormal vibration occurs (inspect the mower for damage and make repairs before restarting and operating the mower).
Before clearing blockages.
Whenever you leave the mower. Do Not leave a running machine unattended.
Stop engine, wait for all moving parts to stop:
Before refueling.
Before dumping the grass catcher.
Before making height adjustments.
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 allow children to operate the machine.
Do Not carry children, even with the blades shut off. Children could fall off and be seriously injured or interfere with the safe operation of the machine. Children that have been given rides in the past could suddenly appear in the working area for another ride and be run over or backed over by the machine.
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, the operator must:
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.
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 counter weights.
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.
The blade-control switch (PTO) starts and stops the mower blades and any powered attachments.
You can move the throttle control between FAST and SLOW positions (Figure 21).
Always use the FAST position when engaging the PTO.
Use the choke to start a cold 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 23).
Engage the parking brake; refer to Park Position.
Move the throttle control to the FAST position.
Turn the key to the OFF position and remove the key.
Children or bystanders may be injured if they move or attempt to operate the machine while it is unattended.
Always remove the key and engage the parking brake when leaving the machine unattended.
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 25).
Move the levers to the center, unlocked position.
To go backward, slowly pull the motion-control levers rearward (Figure 26).
The Smart Speed TM Control-System lever (Figure 27 or Figure 28) 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.

This is the fastest speed. The suggested uses for this speed are as follows:
Normal mowing
Moving the machine
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 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 OFF position, rotate the key switch to the OFF position, and remove the key from the key switch.
Make sure that the grass deflector is in the down position.
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 NEUTRAL-LOCK 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 30 to match the closest height-of-cut position.
Whenever you change the height of cut, it is recommended to adjust the height of the anti-scalp rollers.
Disengage the blade-control switch (PTO), move the motion-control levers to the NEUTRAL-LOCK 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.
Remove the flange nut, anti-scalp roller, and bolt from the bracket (Figure 31).
Note: Keep the bolt and anti-scalp roller together when removing.
Align the bolt and anti-scalp roller in the hole of the bracket that matched the closest height-of-cut position (Figure 31).
Insert the bolt into the bracket hole and secure the bolt and anti-scalp roller with the flange nut (Figure 31).
Use only attachments and accessories approved by Toro.
If you attach a bucket to the engine guard, use a strap to secure it.
Important: If you are carrying more than 4.5 kg (10 lb) in a bucket attached to the engine guard, you should equip your machine with the Bucket Support Kit.
Contact your authorized Toro service dealer.
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 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.
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.
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 deck after each use. If grass and dirt build up inside the mower deck, 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.
Park machine on level ground, disengage drives, set parking brake, stop engine, remove key or disconnect spark plug wire. Wait for all movement to stop and allow the machine to cool before adjusting, cleaning, repairing, or storing. Never allow untrained personnel to service machine.
Clean the machine as stated in the Maintenance section. Keep engine and engine area free from accumulation of grass, leaves, excessive grease or oil, and other debris which can accumulate in these areas. These materials can become combustible and may result in a fire.
Frequently check for worn or deteriorating components that could create a hazard. Tighten loose hardware.
Use a heavy-duty trailer or truck to transport the machine. Ensure that the trailer or truck has all necessary lighting and marking as required by law. Thoroughly read all of the safety instructions. Knowing this information could help you, your family, pets, or bystanders avoid injury.
To transport the machine:
Lock the brake and block the wheels.
Be sure the fuel shut-off valve is closed.
Securely fasten the machine to the trailer or truck with straps, chains, cable, or ropes. Only use the four designated tie-down locations on the mower–two on the left side and two on the right (Figure 32). Use these locations even when transporting the mower with an attached accessory. Using non-designated locations may cause damage to the mower and/or attachment.
Secure a trailer to the towing vehicle with safety chains.
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 machine on a public street or roadway.
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 ramps and drive forward down ramps (Figure 33).
Important: Do not use narrow individual ramps for each side of the machine.
Ensure the ramp is long enough so that the angle with the ground does not exceed 15 degrees (Figure 33). On flat ground, this requires a ramp to be at least four times (4X) as long as the height of the trailer or truck bed to the ground. A steeper angle may cause mower components to get caught as the unit moves from the ramp to the trailer or truck. Steeper angles may also cause the machine to tip or lose control. If loading on or near a slope, position the trailer or truck so that it is on the down side of the slope and the ramp extends up the slope. This will minimize the ramp angle.
Loading a machine onto a trailer or truck increases the possibility of tip-over and could cause serious injury or death.
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 the length of ramp is at least four times (4X) as long as the height of the trailer or truck bed to the ground. This will ensure that 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.
Do not attach towed equipment except at the hitch point.
Follow the attachment manufacturer's recommendation for weight limits for towed equipment and towing on slopes. Towed weight must not exceed the weight of the machine, operator, and ballast; otherwise hydrostatic transmission failure may occur. Use counterweights or wheel weights as described in the attachment manufacturer's manual.
Never allow children or others in or on towed equipment.
On slopes, the weight of the towed equipment may cause loss of traction, increased risk of rollover, and loss of control. Reduce the towed weight and slow down.
Stopping distance increases with the weight of the towed load. Travel slowly and allow extra distance to stop.
Make wide turns to keep the attachment clear of the machine.
Important: Always push the machine by hand. Do not tow the machine, because towing may damage it.
This machine has an electric-brake mechanism, and to push the machine, the ignition key must be in the RUN position. The battery needs to be charged and functioning to disengage the electric brake.

Prepare the machine for storage when non-use occurs over 30 days. Prepare the machine for storage as follows:
Add a petroleum-based stabilizer/conditioner to fuel in the tank. Follow mixing instructions from the stabilizer manufacturer. Do not use an alcohol-based stabilizer (ethanol or methanol).
Note: A fuel stabilizer/conditioner is most effective when mixed with fresh fuel and used at all times.
Run the engine to distribute conditioned fuel through the fuel system (5 minutes).
Shut off the engine, allow it to cool, and drain the fuel tank.
Start the engine and run it until it stops.
Dispose of fuel properly. Recycle the fuel according to local codes.
Important: Do not store stabilizer/conditioned fuel over 90 days.
Remove and check the condition of the spark plug(s); refer to Servicing the Spark Plug. With the spark plug(s) removed from the engine, pour 30 ml (2 tablespoons) of engine oil into the spark plug hole. Use the starter to crank the engine and distribute the oil inside the cylinder. Install the spark plug(s). Do not install the wire on the spark plug(s).
Check and tighten all bolts, nuts, and screws. Repair or replace any part that is damaged.
Paint all scratched or bare metal surfaces. Paint is available from your Authorized Service Dealer.
Store the machine in a clean, dry garage or storage area. Remove the key from the switch and keep it out of reach of children or other unauthorized users. Cover the machine to protect it and keep it clean.
Fully charge the battery.
Let the battery rest for 24 hours, then check the battery voltage.
Note: If the battery voltage is below 12.6 V, repeat steps 1 and 2.
Disconnect the cables from the battery.
Check the voltage periodically to ensure that the voltage is 12.4 V or higher.
Note: If the battery voltage is below 12.4 V, repeat steps 1 and 2.
Store the battery in a cool, dry area in an upright position.
Do not stack batteries directly on top of each other, unless they are in cartons.
Do not stack more than 3 batteries (only 2 if the battery type is commercial).
Test a wet battery every 4 to 6 months and charge it, if necessary.
Always test and charge the battery before installation.
