Safety
This tractor meets or exceeds the B71.1±1998 specifications of the American National Standards Institute in effect at the time of production.
Read and understand the contents of this manual before operating the tractor.
This is the safety alert symbol. It is used to alert you to potential personal injury hazards. Obey all safety messages that follow this symbol to avoid all possible injury or death.
Safe Operating Practices
The following instructions are from ANSI standard B71.1Ð1998.
This product is capable of amputating hands and feet and throwing objects. Always follow all safety instructions to avoid serious injury or death.
General Operation
•Read, understand, and follow all instructions in the operator's manual and on the machine before starting.
•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.
•Be aware of the mower discharge direction and do not point it at anyone. Do not operate the mower without either the entire grass catcher or the guard in place.
•Slow down before turning.
•Never leave a running machine unattended. Always turn off blades, set parking brake, stop engine, and remove keys before dismounting.
•Turn off blades when not mowing.
•Stop the engine before removing the grass catcher or unclogging the chute.
•Mow only in daylight or good artificial light.
•Do not operate the machine while under the influence of alcohol or drugs.
3
•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 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.
Slope Operation
Slopes are a major factor related to loss-of-control and tip-over accidents, which can result in severe injury or death. All slopes require extra caution. If you cannot back up the slope or if you feel uneasy on it, do not mow it.
•Mow up and down slopes, not across.
•Remove obstacles such as rocks, tree limbs, etc.
•Watch for holes, ruts or bumps. Uneven terrain could overturn the machine. Tall grass can hide obstacles.
•Use slow speed. Choose a low gear so that you will not have to stop or shift while on the slope.
•Follow Toro's recommendations for wheel weight or counterweights to improve stability.
•Use extra care with grass catchers or other attachments. These can change the stability of the machine.
•Keep all movement on slopes slow and gradual. Do not make sudden changes in speed or direction.
•Avoid starting or stopping on a slope. If tires lose traction, disengage the blades and proceed slowly straight down the slope.
•Do not turn on slopes unless necessary, and then, turn slowly and gradually downhill, if possible.
•Do not mow near drop-offs, ditches, or embankments. The machine could suddenly turn over if a wheel goes over the edge of a cliff or ditch, or if an edge caves in.
•Do not mow on wet grass. Reduced traction could cause sliding.
•Do not try to stabilize the machine by putting your foot on the ground.
•Do not use a grass catcher on steep slopes.
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, look behind and down 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.
•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.
±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 run a machine inside a closed area.
•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. Allow the machine to cool before storing.
•Stop and inspect the equipment if you strike an object. Repair, if necessary, before restarting.
•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 manufacturer's recommended parts, when necessary.

Gasoline and Oil
Recommended Gasoline
Use unleaded regular gasoline suitable for automotive use (85 pump octane minimum). You may use leaded regular gasoline 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.
•Do not fill the fuel tank completely full. Add gasoline to the fuel tank until the level is 1/4 to 1/2 in. (6 to 13 mm) below the bottom of the filler neck. This empty space in the tank allows the gasoline to expand.
•Never smoke when handling gasoline, and stay away from an open flame or where a spark may ignite the gasoline fumes.
•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, refuel such equipment on a truck or trailer from a portable container, not from a gasoline dispenser nozzle.
•If you must use a gasoline dispenser, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.
Using Stabilizer/Conditioner
Use a fuel stabilizer/conditioner in the tractor to provide the following benefits:
•It keeps gasoline fresh during storage for up to 90 days. For longer storage, drain the fuel tank.
•It cleans the engine while it runs.
•It 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 gasoline.
Note: A fuel stabilizer/conditioner is most effective when it is mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use a fuel stabilizer/conditioner at all times.
Filling the Fuel Tank
1.Stop the engine and wait for all moving parts to stop.
2.Set the parking brake.
3.Clean around the fuel tank cap and remove the cap.
4.Add unleaded regular gasoline to the fuel tank until the level is 1/4 to 1/2 in. (6 to 13 mm) below the bottom of the filler neck. Do not fill the fuel tank completely full.
Note: This space in the tank allows gasoline to expand.
5.Install the fuel tank cap securely.
6.Wipe up any gasoline that spills.
Checking the Engine Oil Level
Before you start the engine and use the tractor, check the oil level in the engine crankcase; refer to Checking the Oil Level on page 20.
