symbol, which means

Safe Operating Practices

The following instructions are from the CEN standard EN 836:1997, ISO standard 5395:1990, and ANSI B71.4-1999.

Training

• Read the operator’s manual and other training material

carefully. Be familiar with the controls, safety signs, and the proper use of the equipment.

• If the operator or mechanic can not read the language of

this manual, it is the owner’s responsibility to explain this material to them.

Serial No.

This manual identifies potential hazards and has special safety messages that help you and others avoid personal injury and even death. Danger, Warning, and Caution are signal words used to identify the level of hazard. However, regardless of the hazard, be extremely careful.

Danger signals an extreme hazard that will cause serious injury or death if you do not follow the recommended precautions.

Warning signals a hazard that may cause serious injury or death if you do not follow the recommended precautions.

Caution signals a hazard that may cause minor or moderate injury if you do not follow the recommended precautions.

This manual uses two other words to highlight information.

Important calls attention to special mechanical

information and Note: emphasizes general information worthy of special attention.

Safety

This machine meets or exceeds CEN standard EN 836:1997 (when appropriate decals applied), and ANSI B71.4-1999 specifications in effect at the time of production when equipped with required weights as listed in the weight chart.

• Never allow children or people unfamiliar with these

instructions to use or service the mower. Local regulations may restrict the age of the operator.

• Never mow while people, especially children, or pets

are nearby.

• Keep in mind that the operator or user is responsible for

accidents or hazards occurring to other people or their property.

• Do not carry passengers.

• All drivers and mechanics should seek and obtain

professional and practical instruction. The owner is responsible for training the users. 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 brake. The main reasons for loss of control are:

• insufficient wheel grip;

• being driven too fast;

• inadequate braking;

• the type of machine is unsuitable for the task;

• lack of awareness of the effect of ground

conditions, especially slopes;

• The owner/user can prevent and is responsible for

accidents or injuries occurring to himself or herself, other people, or property.

Preparation

• While mowing, always wear substantial footwear, long

trousers, hard hat, safety glasses, and hearing protection. Long hair, loose clothing, or jewelry may get tangled in moving parts. Do not operate the equipment when barefoot or wearing open sandals.

• Thoroughly inspect the area where the equipment is to

be used and remove all objects which may be thrown by the machine.

• Warning—Fuel is highly flammable. Take the

following precautions: – Store fuel in containers specifically designed for this

purpose.

– Refuel outdoors only and do not smoke while

refueling.

– Add fuel before starting the engine. Never remove

the cap of the fuel tank or add fuel while the engine is running or when the engine is hot.

– If fuel is spilled, do not attempt to start the engine

but move the machine away from the area of spillage and avoid creating any source of ignition until fuel vapors have dissipated.

– Replace all fuel tank and container caps securely.

• Replace faulty silencers/mufflers.

• 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 the manufacturer.

• Check that operator’s presence controls, safety switches

and shields are attached and functioning properly. Do not operate unless they are functioning properly.

• EU (European Union) standard EN836 requires a

maximum slope usage angle statement. This stated angle is 50% of the smallest angle recorded during the of stability test. For this product this statement is; Do not use on slopes of more than 10°.

• Remember there is no such thing as a safe slope. Travel

on grass slopes requires particular care. To guard against overturning:

– do not stop or start suddenly when going up or

downhill;

– machine speeds should be kept low on slopes and

during tight turns;

– stay alert for humps and hollows and other hidden

hazards;

– never mow across the face of the slope, unless the

mower is designed for this purpose.

– Use counterweight(s) or wheel weights when

suggested in the operator’s manual.

• Stay alert for holes in the terrain and other hidden

hazards.

• Watch out for traffic when crossing or near roadways.

• Stop the blades from rotating before crossing surfaces

other than grass.

• When using any attachments, never direct discharge of

material toward bystanders nor allow anyone near the machine while in operation.

• Never operate the machine with damaged guards,

shields, or without safety protective devices in place. Be sure all interlocks are attached, adjusted properly, and functioning properly.

• Do not change the engine governor settings or

overspeed the engine. Operating the engine at excessive speed may increase the hazard of personal injury.

• Before leaving the operator’s position:

– stop on level ground;

Operation

• Do not operate the engine in a confined space where

dangerous carbon monoxide fumes can collect.

• Mow only in daylight or in good artificial light.

• Before attempting to start the engine, disengage all

blade attachment clutches, shift into neutral, and engage the parking brake.

• Do not put hands or feet near or under rotating parts.

Keep clear of the discharge opening at all times.

– disengage the power take-off and lower the

attachments; – change into neutral and set the parking brake; – stop the engine and remove the key.

• Disengage drive to attachments when transporting or

not in use.

• Stop the engine and disengage drive to attachment

– before refuelling; – before removing the grass catcher/catchers; – before making height adjustment unless adjustment

can be made from the operator’s position.

– before clearing blockages; – before checking, cleaning or working on the mower; – after striking a foreign object or if an abnormal

vibration occurs. Inspect the mower for damage and make repairs before restarting and operating the equipment.

• Reduce the throttle setting during engine run-out and, if

the engine is provided with a shut-off valve, turn the fuel off at the conclusion of mowing.

• Keep hands and feet away from the cutting units.

• Look behind and down before backing up to be sure of

a clear path.

• Slow down and use caution when making turns and

crossing roads and sidewalks. Stop blades from rotating.

• Be aware of the mower discharge direction and do not

point it at anyone.

• Do not operate the mower under the influence of

alcohol or drugs

• Use care when loading or unloading the machine into a

trailer or truck

• Use care when approaching blind corners, shrubs, trees,

or other objects that may obscure vision.

• Disengage drives, lower the cutting units, set parking

brake, stop engine and remove key and disconnect spark plug wire (gas engine only). Wait for all movement to stop before adjusting, cleaning or repairing.

• Clean grass and debris from cutting units, drives,

silencers/mufflers, and engine to help prevent fires. Clean up oil or fuel spillage.

• Use jack stands to support components when required.

• Carefully release pressure from components with stored

energy.

• Disconnect battery and remove spark plug wire (gas

engine only) before making any repairs. Disconnect the negative terminal first and the positive last. Reconnect positive first and negative last.

• Use care when checking the blades. Wear gloves and

use caution when servicing them.

• Keep hands and feet away from moving parts. If

possible, do not make adjustments with the engine running.

• Charge batteries in an open well ventilated area, away

from spark and flames. Unplug charger before connecting or disconnecting from battery. Wear protective clothing and use insulated tools.

Maintenance and Storage

• Keep all nuts, bolts and screws tight to be sure the

equipment is in safe working condition.

• Never store the equipment with fuel in the tank inside a

building where fumes may reach an open flame or spark.

• Allow the engine to cool before storing in any

enclosure.

• To reduce the fire hazard, keep the engine,

silencer/muffler, battery compartment and fuel storage area free of grass, leaves, or excessive grease.

• Check the grass catcher frequently for wear or

deterioration.

• Keep all parts in good working condition and all

hardware and hydraulic fittings tightened. Replace all worn or damaged parts and decals.

• If the fuel tank has to be drained, do this outdoors.

• Be careful during adjustment of the machine to prevent

entrapment of the fingers between moving blades and fixed parts of the machine.

• On multi-spindle mowers, take care as rotating one

blade can cause other blades to rotate.

Toro Riding Mower Safety

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, ISO, or ANSI standard.

This product is capable of amputating hands and feet and throwing objects. Always follow all safety instructions to avoid serious injury or death.

Use of this product for purposes other than its intended use could prove dangerous to user and bystanders.

Warning

Engine exhaust contains carbon monoxide, which is an odorless, deadly poison that can kill you.

Do not run engine indoors or in an enclosed area.

• Know how to stop the engine quickly.

• Do not operate the machine while wearing tennis shoes

or sneakers.

• Wearing safety shoes and long pants is advisable and

required by some local ordinances and insurance regulations.

• Handle fuel carefully. Wipe up any spills.

• Check the safety interlock switches daily for proper

operation. If a switch should fail, replace the switch before operating the machine. After every two years, replace all interlock switches in the safety system, whether they are working properly or not.

• Before starting the engine, sit on the seat.

• Using the machine demands attention. To prevent loss

of control: – Do not drive close to sand traps, ditches, creeks,

embankments, or other hazards.

– Reduce speed when making sharp turns. A void

sudden stops and starts.

– When near or crossing roads, always yield the

right-of-way.

Maintenance and Storage

• Make sure all hydraulic line connectors are tight and all

hydraulic hoses and lines are in good condition before applying pressure to the system.

• Keep your body and hands away from pin hole leaks or

nozzles that eject hydraulic fluid under high pressure. Use paper or cardboard, not your hands, to search for leaks. Hydraulic fluid escaping under pressure can have sufficient force to penetrate the skin and cause serious injury. Seek immediate medical attention if fluid is injected into skin.

• Before disconnecting or performing any work on the

hydraulic system, all pressure in the system must be relieved by stopping the engine and lowering the cutting units and attachments to the ground.

– Apply the service brakes when going downhill to

keep forward speed slow and to maintain control of the machine.

• When operating a machine on slopes, by banks, or drop

offs, always have ROPS (roll–over protection system) installed.

• When operating a machine with ROPS (roll–over

protection system) always use the seat belt and make sure seat pivot retainer pin is installed (GM only).

• Raise the cutting units when driving from one work

area to another.

• Do not touch the engine, silencer/muffler, or exhaust

pipe while the engine is running or soon after it has stopped because these areas could be hot enough to cause burns.

• On any hill, there is the possibility of tipping or rolling

over, but the risk increases as the slop angle increases. Steep hills should be avoided.

– Cutting units must be lowered when going down

slopes to maintain steering control

• Engage traction drive slowly, always keep foot on

traction pedal, especially when traveling downhill. – Use reverse on traction pedal for braking.

• If the machine stalls when climbing a slope, do not turn

the machine around. Always back slowly, straight down the slope.

• Check all fuel lines for tightness and wear on a regular

basis. Tighten or repair them as needed.

• If the engine must be running to perform a maintenance

adjustment, keep hands, feet, clothing, and any parts of the body away from the cutting units, attachments, and any moving parts.

• To ensure safety and accuracy, have an Authorized Toro

Distributor check the maximum engine speed with a tachometer.

• If major repairs are ever needed or if assistance is

desired, contact an Authorized Toro Distributor.

• Use only Toro-approved attachments and replacement

parts. The warranty may be voided if used with unapproved attachments.

Before Operating

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

Checking the Engine Oil

The engine is shipped with 8.5 qt. (8 l) of oil in the crankcase. However, check level of oil before and after the engine is first started.

The engine uses any high quality detergent oil having the American Petroleum Institute (API) “service classification” CD. Oil viscosity recommendations are:

Figure 3

1. Dipstick

Figure 4

1. Engine oil fill cap

Important Check oil after every 5 hours operation or

daily. Change oil and filter after the first 50 hours, then change both every 100 hours operation thereafter. Change oil and filter more frequently when engine is operated in extremely dusty or dirty conditions.

4. Insert dipstick into tube and close and latch hood.

Checking the Cooling System

The cooling system is filled with a 50/50 solution of water and permanent ethylene glycol anti-freeze. Check coolant level at beginning of each day before starting the engine. Capacity of cooling system is approximately 3.9 gal. (14.7 l).

Caution

If the engine has been running, the pressurized, hot coolant can escape and cause burns.

• Do not open the radiator cap when the engine is

running.

• Use a rag when opening the radiator cap, and

open the cap slowly to allow steam to escape.

Checking the Hydraulic System Fluid

1. Fluid level should be checked daily through sight glass

at rear of hydraulic reservoir (Fig. 6). When oil is cold, level will be slightly below center, but should be in the middle of the sight glass when the oil is warm.

Figure 6

1. Hydraulic oil level sight glass

2. Reservoir fill cap

1. Unlatch, raise and prop hood open. Make sure hood

prop is secured in one of the mounting brackets on hood.

2. Remove radiator cap (Fig. 5). Level of coolant must be

above the radiator core and about 1 in. (25 mm) below bottom of filler neck.

Figure 5

1. Radiator cap

3. If coolant level is low, add a 50/50 mixture of water and ethylene glycol anti–freeze. Do not use

alcohol/methanol base coolants or water only. Do not overfill.

2. If oil level is low, add hydraulic oil to the reservoir

(Fig. 6); refer to Servicing the Hydraulic System, page 41.

Filling the Fuel Tank

The engine runs on ASTM No. 2-D diesel fuel.

Danger

Under certain conditions, diesel fuel and fuel vapors are highly flammable and explosive. A fire or explosion from fuel can burn you and others and can cause property damage.

• Use a funnel and fill the fuel tank outdoors, in

an open area, when the engine is off and is cold. Wipe up any fuel that spills.

• Do not fill the fuel tank completely full. Add fuel

to the fuel tank until the level is 1 in. (25 mm) below the bottom of the filler neck. This empty space in the tank allows the fuel to expand.

• Never smoke when handling fuel, and stay away

from an open flame or where fuel fumes may be ignited by a spark.

• Store fuel in a clean, safety-approved container

and keep the cap in place.

4. Install radiator cap, close and latch the hood.

1. Remove fuel tank cap (Fig. 7).

2. Fill tank to about 1 in. (25 mm) below bottom of filler

neck with No. 2 diesel fuel. Install cap.

Checking the Tire Pressure

Since the machine can be operated under many different types of turf conditions, proper tire pressure is very important. Use the following as a guide:

• Under Normal mowing conditions and when used on a

wide variety of turf grasses: 15 psi (103.4 kPa) front; 13 psi (89.6 kPa) rear. 50 psi (344.7 kPa) castors.

• When turf is wet and softer than normal, use low

pressure: 12 psi (82.7 kPa) front and 9 psi (62 kPa) rear.

• When turf is dry and harder than normal, use higher tire

pressure: 18 psi (124 kPa) front and rear.

Important Do not operate in HIGH RANGE for

extended periods when tire pressure is less than 18 psi because tires may be damaged. When tire pressure exceeds 18 psi, HIGH RANGE may be used.

Checking Systems Operation

Start engine. Move the machine, slowly, to an area where the machine can be checked for proper function. Check operation of controls, safety interlock system, engine, hydraulic system, brakes and cutting units; refer to Operation, page 20, for proper procedures.

Checking Cutting Unit Mismatch

To ensure all cutting units are at the same height-of-cut:

1. Adjust all cutting units to the highest height–of–cut.

Position all castor arm height-of-cut spacers to on the underside of the castor arms. Do not move washers. Leave them in their original position.

Note: Unless all castor wheel axles are not in the same location, axles do not have to be relocated. All, however must be in the same holes (Fig. 8).

2. Place a flat 4’x8’ sheet of 3/4 in. plywood on a level

surface and lower a cutting unit onto the plywood.

3. Taking each cutting blade in turn, position blade so it

faces fore and aft. Measure from plywood to front tip of cutter blade and record dimension. All blade heights on same deck should be within 1/4 in. (6.3 mm) of one another. If blade heights meet criteria, proceed to step 5. If blade heights are not within 1/4 in. (6.3 mm), proceed to step 4.

4. To match cutting blade height, transfer washers from

one side of a castor wheel arm to the other. If end is to be lowered, transfer one or both washers from the underside to the top. By contrast, if end is to be raised, transfer washer(s) from the top to the underside. Each washer is 1/8 in. (3 mm) thick. Repeat measurement of blade tip height and record new dimensions.

5. Repeat steps 2–3 on remaining cutting units, and step 4,

if necessary. If washers are transferred on a outboard cutting unit castor arm, be sure to transfer the same number on both ends of the castor arm.

6. Compare blade height dimensions of all cutting units.

Blade heights must be within 3/8 in. (9.5 mm) of one another. If they are not, determine which cutting unit height can be changed to compensate for difference and either transfer washers from bottom to top to lower unit, or from top to bottom to raise. Transfer an equal number of washers at all castor wheel locations to keep cutting unit level—two on front unit, four on outboard units.

Adjusting the Height of Cut

The height-of-cut is adjustable from 1 to 5-1/2 in. (25 to 140 mm) in 1/2 in. (13 mm) increments. Positioning the castor wheel axles in the top holes of the castor forks (Fig. 8) allows Low range height-of-cut settings from 1 to 4 in. (25 to 102 mm); positioning the castor wheel axles in the lower holes of the castor forks (Fig. 8) allows High range height-of-cut settings from 2-1/2 to 5-1/2 in. (63.5 to 140 mm).
