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 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

The following instructions are from ANSI standard B71.I-2003.

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.

• 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 awone enters the area.

• Never carry passengers.

• Do not mow in reverse unless absolutely necessar> 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 m W 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 malting turns. Look behind and to the side before changing

directions.

• Neverleavearunningmachineunattended.Always turnoff blades,setparkingbrake,stopengine,and

• Watchfor trafficwhenoperatingnearorcrossing

roadways.

• Useextracarewhenloadingor unloadingthe

machineinto atraileror truck.

Alwaysweareyeprotectionwhenoperatingthe

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 injur):

• Always follow the recommendations for wheel

weights or counterweights.

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 wheel motors engaged when going down slopes.

• Reduce speed and use extreme caution on slopes.

• 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. \Vcight 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-off-s, ditches, steep banks or water. Wheels dropping over edges can cause

rollovers, which may result in serious injur B death or drowning.

• Use a walk behind mower and/or a hand trimmer near drop-off_, ditches, steep banks or water.

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 activit> 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

approvedhitch.Thefollowingguidelinesapplywhen towingwith theapprovedhitchkit 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.

Keep nuts and bolts tight, especially the blade attachment bolts. Keep equipment in good

condition.

Never tamper with safcty devices. Check their proper operation regularl 3.

Height-of-Cut Lever

The height of cut lever allows the operator to lower and raise the deck from the seated position. When the lever is moved up, toward the operator the deck is raised

from the ground and when moved down, away from the operator it is lowered toward the ground. Only adjust the height of cut while machine is not moving (Figure 18).

Foot Assist Pedal (Model 74375 only)

The foot assist pedal allows the operator to support the weight of the deck with their leg during adjusting the deck height via the height-of-cut lever.

Motion Control Levers and Park Position

The motion control levers are speed sensitive controls of independent wheel motors. Moving a lever forward or

backward turns the wheel on the same side forward or in

Operation

Note: Determine the leKt 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 famil5 pets or bystanders avoid

injur>

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.

Recommended Fuel

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 percent ethanol because the fuel system could be damaged. Do not mix oil with gasoline.

• 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 body of

the tank is full but fuel does not fill the neck of the tank. 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

which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property.

• Mways 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.

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 30 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.

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 rimes.

Gasoline/Alcohol blends

Gasohol (up to 10 percent ethyl alcohol, 90 percent

unleaded gasoline by volume) is approved for fuel use by the engine manufacturer. Other gasoline/alcohol

blends, such as E85, are not approved.

Gasoline/Ether blends

Methyl Tertiary Butyl Ether (MTBE) and unleaded gasoline blends (up to a maximum of i5 percent MTBE

by volume) are approved for fuel use by the engine manufacturer. Other gasoline/ether blends are not

approved.

Fuel Gauge

Use the fuel window below the operator to veri_T the level of gasoline before filling the tank (Figure 8).

tank (Figure 9). This space in the neck of the tank allows gasoline to expand. Do not fill the fuel tank

completely full.

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

Pushing the Machine by Hand

Important: Always push the machine by hand.

Never tow the machine because damage may

occur.

To Push the Machine

1. Park the machine on a level surface and disengage the blade control switch.

Move the motion control levers outward to park position, stop the engine, remove the keB and wait

for all moving parts to stop before leaving the

operating position.

Locate the bypass levers at the rear of the machine, on the left and right side of the frame.

Side Discharge

"['he mower has a hinged grass deflector that disperses clippings to the side and down toward the turf.

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 blade control

switch to Off and rotate the ignition key to Off. Mso remove the key and pull the wire off the spark plug(s).

Operating Tips

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

Normall3; mow every fi)ur 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.

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 flee 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 113of the Grass Blade

It is best to cut only about i/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

slowl>

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 fi)rward 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 unsatisfactor).

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 aW wear or damage. File

down aW nicks and sharpen the blades as necessar> If

a blade is damaged or worn, replace it immediately with

a genuine Toro replacement blade.

Maintenance

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

Changing the Oil and the Filter

Service Interval: Every I00 hours--Change the engine

oil and filter.

Refill with service class SG, SH, SJ or higher oil as

specified in the "Viscosity Grades" table.

Change the oil and filter while the engine is still warm. The oil will flow more freely and carry away more

impurities. Make sure the engine is level when filling, checldng, or changing the oil.

Change the oil and oil filter as follows:

1. Start the engine and let it run until warm. This

warms the oil so it drains better.

Park the machine so that the drain side is slightly lower than the opposite side to assure the oil drains

completely

Disengage the blade control switch and move the motion controls outward to the park position.

Stop the engine, remove the ke5 and wait for all

moving parts to stop before leaving the operating position.

Locate the oil drain hose on the left side of the

engine. The drain plug is attached to a drain hose

routed through a drain hole in the machine frame

(Figure 29). Clean the area around the oil drain plug cap and the oil drain hose.

Place a pan underneath machine directly below the

oil drain hose as shown in Figure 29.
