All drivers should seek and obtain professional and practical instruction. Such instruction should emphasize:
the need for care and concentration when working with ride-on machines;
control of a ride-on machine sliding on a slope will not be regained by the application of the control levers. The main reasons for loss of control are:
insufficient wheel grip, especially on wet grass;
being driven too fast;
inadequate braking;
the type of machine is unsuitable for its task;
lack of awareness of the effect of ground conditions, especially slopes;
incorrect hitching and load distribution.
While mowing, always wear substantial, slip-resistant footwear and long trousers. Do not operate the equipment when barefoot or wearing open sandals.
Thoroughly inspect the area where you will use the equipment and remove all objects, which the machine may throw.

The following list contains safety information specific to Toro products or other safety information that you must know that is not included in the CEN standard.
Engine exhaust contains carbon monoxide, which is an odorless, deadly poison that can kill you. Do not run the engine indoors or in an enclosed area.
Keep your hands, feet, hair and loose clothing away from attachment discharge area, the underside of the mower, and any moving parts while engine is running.
Do not touch the equipment or attachment parts which may be hot from operation. Allow them to cool before attempting to maintain, adjust, or service them .
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 the battery.
Use only genuine Toro replacement parts to maintain the original standards.
Use only Toro-approved attachments. You may void the warranty if you use unapproved attachments.
Do not mow slopes greater than 15 degrees.
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.
Do not mow slopes when grass is wet. Slippery conditions reduce traction and could cause sliding and a loss of control.
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.
Reduce speed and use extreme caution on slopes.
Remove or mark obstacles such as rocks, tree limbs, etc. from the mowing area. Tall grass can hide obstacles.
Watch for ditches, holes, rocks, dips, and rises that change the operating angle, as rough terrain could overturn the machine.
Avoid sudden starts when mowing uphill, because the mower may tip backward.
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.
Follow the manufacturer's recommendations for wheel weights or counterweights to improve stability.
Use extreme care with grass catchers or other attachments. These can change the stability of the machine and cause a loss of control.

Note: Determine the left and right sides of the machine from the normal operating position.
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 a fuel stabilizer is used.
Do not add oil to gasoline.
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 6 to 13 mm (1/4 to 1/2 inch) 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.
In certain conditions during fueling, static electricity can be released, causing a spark that 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 you must use a gasoline-dispenser nozzle, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.
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 bottle opening.
Avoid contact with skin; wash off spills with soap and water.
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 gasoline stabilizer/conditioner to the gasoline.
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.
Shut the engine off and set the parking brake.
Clean around the fuel tank cap and remove the cap. Add unleaded regular gasoline 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 space in the tank allows the gasoline to expand. Do not fill the fuel tank completely full.
Install the fuel tank cap securely. Wipe up any spilled gasoline.
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.

Hands may become entangled in the rotating drive components below the engine deck, which could result in serious injury.
Stop the engine, remove the key, and allow all moving parts to stop before accessing the drive-wheel-release valves.
The engine and hydraulic-drive units can become very hot. Touching a hot engine or hydraulic-drive units can cause severe burns.
Allow the engine and hydraulic-drive units to cool completely before accessing the drive-wheel-release valves.
The drive-wheel-release valves are located behind the seat and down in the engine compartment.
Disengage the blade-control switch (PTO), turn the ignition key to off, move the levers to the NEUTRAL-LOCK position, apply the parking brake, and remove the key.
Locate the bypass levers behind the seat, down on the left and right side of the frame.
To push the machine, move both bypass levers rearward and out to lock them into place (Figure 28).
Disengage the parking brake before pushing the machine.
To run the machine, move the bypass levers to the FORWARD position (Figure 28).
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 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.
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.
To transport the machine:
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.
Stop the engine, remove the key, set the brake, and close the fuel valve.
Use the metal tie-down loops on the machine to securely fasten the it to the trailer or truck with straps, chains, cable, or ropes (Figure 29).
Use extreme caution when loading or the unloading machine 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 ramps and drive it forward down the ramps (Figure 30).
Important: Do not use narrow individual ramps for each side of the machine.
Ensure that the ramp is long enough so that the angle with the ground does not exceed 15 degrees (Figure 31). On flat ground, this requires a ramp to be at least 4 times 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 machine moves from the ramp to the trailer or truck. Steeper angles may also cause the machine to tip or lose control. If you are loading the machine 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 minimizes the ramp angle.
Loading a machine onto a trailer or truck increases the possibility of a tip-over and could cause serious injury or death.
Use extreme caution when operating a machine on a ramp.
Ensure that the ROPS is in the up position and use the seat belt when loading or unloading the machine. Ensure that the ROPS clears the top of an enclosed trailer.
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 ramp angle does not exceed 15 degrees on flat ground.
Back the machine up the ramps and drive it forward down the 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.
The Z Stand raises the front end of the machine to allow you to clean the mower and remove the blades.
The machine could fall onto someone and cause serious injury or death.
Use extreme caution when operating the machine on the Z Stand.
Use only for cleaning the mower and removing the blades.
Do not keep the machine on the Z Stand for extended periods of time.
Always turn the engine off, set the parking brake, and remove the key before performing any maintenance to the mower.
Important: Use the Z Stand on a level surface.
Raise the mower to the transport position.
Remove the bracket pin (Figure 32).
Raise the latch.
Swing the stand foot out front and slide it toward machine, into the bottom of slot (Figure 32 and Figure 33).
Set the foot of the stand on the ground and rest the latch on the pivot tab (Figure 33).
Start the engine and put it at half throttle.
Note: For best results, place the foot of the stand into the seams in sidewalks or into the turf (Figure 33).
Drive the machine onto the stand. Stop when the latch drops over the tab into the locked position (Figure 33).
Engage the parking brake and turn off the engine.
Chock or block the drive wheels.
Parking brake may not hold machine parked on Z Stand and could cause personal injury or property damage.
Do not park on the Z Stand unless the wheels are chocked or blocked.
Perform the maintenance.
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 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 you have used in the past is generally the best 1 to use. When cutting grass longer than 15.24 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 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.
Alternate the mowing direction to keep the grass standing straight. This also helps disperse clippings, which enhances decomposition and fertilization.
Normally, mow every 4 days. However, grass grows at different rates at different times. 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 2 days later at a lower height setting.
To improve cut quality, use a slower ground speed in certain conditions.
If the cutting width of the mower is wider than the mower that you previously used, raise the cutting height to ensure that uneven turf is not cut too short.
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.
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.
Clean clippings and dirt from the underside of the mower after each use. If grass and dirt build up inside the mower, the cutting quality eventually becomes 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 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.

Note: To increase the height, turn the adjuster screw clockwise; to decrease the height, turn it counterclockwise.
Note: If the front deck links do not have enough adjustment to achieve accurate cut height, you can utilize the single-point adjustment to gain more adjustment.
To adjust the single-point system, loosen the 2 bolts at the bottom of the height-of-cut plate (Figure 79).
If the deck is too low, tighten the single-point adjustment bolt by rotating it clockwise. If the deck is too high, loosen the single-point adjustment bolt by rotating it counterclockwise (Figure 80).
Note: Loosen or tighten the single-point adjustment bolt enough to move the height-of-cut plate mounting bolts at least 1/3 the length of the available travel in their slots. This regains some up and down adjustment on each of the 4 deck links.
Tighten the 2 bolts at the bottom of the height-of-cut plate (Figure 79).
Note: For most conditions, adjust the back blade tip 4 mm (1/4 inch) higher than the front.
Torque the 2 bolts to 37 to 45 N∙m (27 to 33 ft-lb).
On both sides of the deck, measure from the level surface to the back tip of the blade (postion B) as shown in Figure 77.
Note: The measurement should read 8.3 cm (3-1/4 inches)
Fine-tune the screw adjuster by turning it to get 8.3 mm (3-1/4 inches) height (Figure 78).
Note: To increase the height, turn the adjustment nut clockwise; to decrease the height, turn it counterclockwise.
Measure until all 4 sides are the correct height.
Tighten all the nuts on the deck-lift-arm assemblies.
Lower the discharge chute.
To ensure a superior quality of cut, keep the blades sharp. For convenient sharpening and replacement, keep extra blades on hand.
A worn or damaged blade can break, and a piece of the blade could be thrown at you or bystanders, resulting in serious personal injury or death.
Inspect the blades periodically for wear or damage.
Replace a worn or damaged blade.
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, and disconnect the spark plug wires from the spark plugs.

Inspect the cutting edges (Figure 81).
If the edges are not sharp or have nicks, remove and sharpen the blade; refer to Removing the Blades and 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 81).
Disengage the blade-control switch (PTO), move the motion-control levers to the NEUTRAL-LOCK position, and set the parking brake.
Stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.
Rotate the blades until the ends face forward and backward (Figure 82).
Measure from a level surface to the cutting edge, position A, of the blades (Figure 82).
Rotate the opposite ends of the blades forward.
Measure from a level surface to the cutting edge of the blades at the same position as in step 4.
Note: The difference between the dimensions obtained in steps 4 and 5 must not exceed 3 mm (1/8 inch).
Note: If this dimension exceeds 3 mm (1/8 inch), the blade is bent and must be replaced.
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.
Do not file or create sharp notches in the edges or surfaces of the blade.
Replace a blade if it hits an object, if the blade is out of balance, or if 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 nonconformance with safety standards.
Hold the blade end using a rag or a thickly padded glove.
Remove the blade bolt, curved washer, and blade from the spindle shaft (Figure 83).
Use a file to sharpen the cutting edge at both ends of the blade (Figure 84).
Note: Maintain the original angle.
Note: The blade retains balance if you remove the same amount of material from both cutting edges.
Check the balance of the blade by putting it on a blade balancer (Figure 85).
Note: If the blade stays in a horizontal position, the blade is balanced and ready to use.
If the blade is not balanced, file some metal off the end of the sail area only (Figure 83).
Repeat this procedure until the blade is balanced.
Install the blade onto the spindle shaft (Figure 86).
Important: The curved part of the blade must point upward toward the inside of the mower to ensure proper cutting.
Install the spring disk and blade bolt (Figure 86).
Note: Install the spring-disk cone toward the bolt head.
Torque the blade bolt to 115 to 150 N∙m (85 to 110 ft-lb).
Before servicing or removing the mower deck, lock out the spring-loaded deck arms.
Stop the engine, wait for all moving parts to stop, and remove key. Engage the parking brake.
Remove the height adjustment pin and lower the deck to the ground.
Place the height-adjustment pin in the 7.6 cm (3 inch) cutting-height location.
Remove the belt covers.
Lift up the floor pan and insert a ratchet into the square hole in the deck idler (Figure 87).
Rotate the deck idler clockwise and remove the mower belt (Figure 87).
Remove and retain the shoulder bolt and nut of the rear and front deck-lift attachments on both sides of the machine(Figure 88).
Slide the deck out to the right side of the machine.
An uncovered discharge opening could allow the lawn mower to throw objects at you or bystanders, resulting in serious injury. Also, contact with the blade could occur.
Do not operate the lawn mower unless you install a cover plate, mulch plate, grass deflector, or bagger.
Remove the locknut, bolt, spring, and spacer holding the deflector to the pivot brackets (Figure 89).
Remove the damaged or worn grass deflector (Figure 89).
Place the spacer and the spring onto grass deflector.
Place 1 J-hook end of the spring behind the deck edge.
Note: Make sure that 1 J-hook end of the spring is installed behind the deck edge before installing the bolt as shown in Figure 89.
Install the bolt and the nut.
Place 1 J-hook end of the spring around the grass deflector (Figure 89).
Important: The grass deflector must be able to rotate. Lift the deflector up to the full open position and ensure that it rotates into the full down position.
