Safe Operating Practices

The following instructions are from the CEN standard EN 836:1997, ISO standard 5395:1990, and ANSI B71.4-2004.

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

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

• 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 its task;

• lack of awareness of the effect of ground

conditions, especially slopes;

• incorrect hitching and load distribution.

• 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 tanks 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.

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.

• 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;

– engage clutch slowly, always keep machine in gear,

especially when travelling 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.

Page 5

• Stay alert for holes in the terrain and other hidden

hazards.

• Use care when pulling loads or using heavy equipment.

• Keep hands and feet away from the cutting units.

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

a clear path.

– Use only approved drawbar hitch points.

– Limit loads to those you can safely control.

– Do not turn sharply. Use care when reversing.

– Use counterweight(s) or wheel weights when

suggested in the operator’s manual.

• Watch out for traffic when crossing or near roadways.

• Stop the blades 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;

– 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.

• Slow down and use caution when making turns and

crossing roads and sidewalks. Stop cutting units if not mowing.

• 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.

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.

• Disengage drives, lower the cutting units, set parking

brake, stop engine and remove key and disconnect spark plug wire. 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.

Page 6

• Disconnect battery and remove spark plug wire before

making any repairs. Disconnect the negative terminal first and the positive last. Reconnect positive first and negative last.

• 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.

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.

– This machine is not designed or equipped for

on–road use and is a “slow–moving vehicle.” If you must cross or travel on a public road, you should be aware of and comply with local regulations, such as required lights, slow moving vehicle signs, and reflectors.

– Apply the service brakes when going downhill to

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

• 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.

• If the engine stalls or loses headway and cannot make it

to the top of a slope, do not turn the machine around. Always back slowly, straight down the slope.

• When a person or pet appears unexpectedly in or near

the mowing area, stop mowing. Careless operation, combined with terrain angles, ricochets, or improperly positioned guards can lead to thrown object injuries. Do not resume mowing until the area is cleared.

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.

• 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, or

other hazards.

– Reduce speed when making sharp turns. Avoid

sudden stops and starts.

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.

• 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, especially the screen at the side of the engine. Keep everyone away.

• To ensure safety and accuracy, have an Authorized Toro

Distributor check the maximum engine speed with a tachometer. Maximum governed engine speed should be 3250 RPM.

3. If oil is below FULL mark, remove fill cap and add oil until level reaches FULL mark on dipstick. DO NOT OVERFILL.

Checking the Crankcase Oil

The engine is shipped with oil in the crankcase; however, the oil level must be checked before and after the engine is first started.

Crankcase capacity is approximately 3.25 qt. (3.1 l) with the filter.

Use high-quality engine oil that meets the following specifications:

API Classification Level Required: CH–4, CI–4 or higher.

Preferred oil: SAE 15W–40 (above 0_F)

Alternate oil: SAE 10W–30 or 5W–30 (all temperatures)

Toro Premium Engine oil is available from your distributor in either 15W–40 or 10W–30 viscosity. See the parts catalog for part numbers.

1. Park machine on a level surface, stop engine and remove key from ignition switch. Open hood and install hood prop.

Page 24

Filling the Fuel Tank

Use only clean, fresh diesel fuel or biodiesel fuels with low (<500 ppm) or ultra low (<15 ppm) sulfur content. The minimum cetane rating should be 40. Purchase fuel in quantities that can be used within 180 days to ensure fuel freshness.

• Use B5 (biodiesel content of 5%) or lesser blends in

cold weather

• Monitor seals, hoses, gaskets in contact with fuel as

they may be degraded over time.

• Fuel filter plugging may be expected for a time after

converting to biodiesel blends.

Fuel tank capacity: 6.5 U.S. gallons (25 l)

Use summer grade diesel fuel (No. 2–D) at temperatures above 20 degrees F (–7 degrees C) and winter grade (No. 1–D or No. 1–D/2–D blend) below that temperature. Use of winter grade fuel at lower temperatures provides lower flash point and cold flow characteristics which will ease starting and reduce fuel filter plugging.

Use of summer grade fuel above 20 degrees F (–7 degrees C) will contribute toward longer fuel pump life and increased power compared to winter grade 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 1/4 to 1/2 in. (6 to 13 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, sealed, safety-approved

container.

Biodiesel Ready

This machine can also use a biodiesel blended fuel of up to B20 (20% biodiesel, 80% petrodiesel). The petrodiesel portion should be low or ultra low sulfur. Observe the following precautions:

• The biodiesel portion of the fuel must meet

specification ASTM D6751 or EN14214.

• The blended fuel composition should meet ASTM

D975 or EN590.

• Contact your distributor if you wish for more

information on biodiesel

1. Tip seat forward and prop it with the support rod so it cannot fall accidentally. Using a clean rag, clean area around fuel tank cap (Fig. 23).

2. Remove cap from the fuel tank and fill the 6-1/2 gallon (25 l) tank to within 1 in. (25 mm) from the top with diesel fuel. Install fuel tank cap tightly after filling tank.

Figure 23

1. Fuel tank cap

Check Cooling System

Clean debris off screen and radiator/oil cooler daily, more often if conditions are extremely dusty and dirty.

The cooling system is filled with a 50 / 50 solution of water and permanent ethylene glycol anti–freeze. Check level of coolant in expansion tank at beginning of each day before starting the engine. Capacity of cooling system is 6 quarts (5.6 l).

Caution

• If engine has been running, pressurized hot

coolant can escape when radiator cap is removed and cause burns.

• Painted surfaces may be damaged by biodiesel blends.

1. Check level of coolant in expansion tank. Coolant level should be between the marks on side of tank.

Page 25

Figure 24

Alternate fluids: If the Toro fluid is not available, other petroleum–based Universal Tractor Hydraulic Fluids (UTHF) may be used provided its specifications fall within the listed range for all the following material properties and it meets industry standards. We do not recommend the use of synthetic fluid. Consult with your lubricant distributor to identify a satisfactory product Note: Toro will not assume responsibility for damage caused by improper substitutions, so use only products from reputable manufacturers who will stand behind their recommendation.

Material Properties:

Viscosity, ASTM D445 cSt @ 40_C 55 to 62

cSt @ 100_C 9.1 to 9.8

Viscosity Index ASTM D2270 140 – 152

Pour Point, ASTM D97 –35_F to –46_F

2. If coolant level is low, remove expansion tank cap and replenish the system. DO NOT OVERFILL.

3. Install expansion tank cap.

Checking the Hydraulic System Fluid

The front axle housing acts as the reservoir for the system. The transmission and axle housing are shipped from the factory with approximately 5 quarts (4.7 l) of high quality hydraulic fluid. However, check fluid level before engine is first started and daily thereafter.

Note: Fluid to operate the power steering is supplied by the hydraulic system transmission charge pump. Cold weather start-up may result in “stiff” operation of the steering until the hydraulic system has warmed up.

The following list is not assumed to be all–inclusive. Hydraulic fluids produced by other manufacturers may be used if they can cross reference to find an equivalent to the products listed. Toro will not assume responsibility for damage caused by improper substitutions, so use only products from reputable manufacturers who will stand behind their recommendation.

Industry Specifications:

API GL–4, AGCO Powerfluid 821 XL, Ford New Holland FNHA–2–C–201.00, Kubota UDT, John Deere J20C, Vickers 35VQ25 and Volvo WB–101/BM.

Note: Many hydraulic fluids are almost colorless, making it difficult to spot leaks. A red dye additive for the hydraulic system oil is available in 2/3 oz. (20 ml) bottles. One bottle is sufficient for 4–6 gal (15–22 1) of hydraulic oil. Order part no. 44–2500 from your authorized Toro distributor.

1. Position machine on a level surface, raise the

implement, and stop the engine.

2. Unscrew dipstick cap (Fig. 25) from the filler neck and

wipe it with a clean rag. Screw dipstick cap finger tight

onto filler neck. Unscrew the dipstick and check level

of fluid. If level is not within 1/2 in. (13 mm) from the

groove in the dipstick (Fig. 25), add enough fluid to

raise level to groove mark. Do not overfill by more

than 1/2 in. (13 mm) above groove.

Checking the Hydraulic System

Operation

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

Controls

Traction Pedal

The traction pedal (Fig. 28) has two functions; one is to make the machine move forward, the other is to make it move backward. Using the heel and toe of the right foot, depress top of pedal to move forward and bottom of pedal to move backward. Ground speed is proportionate to how far pedal is depressed. For maximum ground speed with no load, traction pedal must be fully depressed while throttle is in FAST position. Maximum speed forward is approximately 9.5 mph (15 km/h). To get maximum power under heavy load or when ascending a hill, have throttle in FAST position while depressing traction pedal slightly to keep engine rpm high. When engine rpm begins to decrease, release traction pedal slightly to allow engine rpm to increase.

Brake Pedal

Whenever the engine is shut off, the parking brake (Fig. 28) must be engaged to prevent accidental movement of the machine.

The hydrostatic transmission will not, at any time, act as a parking brake for the machine. To engage parking brake, push down fully on brake pedal and pull parking brake knob out; then release the pedal. To release parking brake, depress brake pedal until parking brake knob retracts. To stop quickly, remove right foot from traction pedal and depress the brake pedal. To permit straight stops, brake cables must be evenly adjusted.

Caution

When foot is removed from the traction pedal, machine should stop; it must not creep in either direction. If machine does creep, do not operate until neutral assembly has been repaired and adjusted; refer to Adjusting Traction Drive for Neutral.

Turn Pedals

The left and right turn pedals (Fig. 28) are connected to the left and right front wheel brakes since both brakes work independently of each other. The brakes can be used to turn sharply or to increase traction if one wheel tends to slip while operating on a hillside. However, wet grass or soft turf could be damaged when brakes are used to turn.

Tilt Steering Control

The tilt steering control is a lever on right side of steering column (Fig. 28). Pull lever rearward to adjust steering wheel to desired fore or aft operating position and push lever forward to lock adjustment.

5. Tilt steering control

Lift Lever

The hydraulic lift lever (Fig. 29) has three positions: FLOAT, TRANSPORT, and RAISE. To lower implement to the ground, move lift lever forward into detent, which is the FLOAT position. The FLOAT position is used for operation and also when machine is not in operation. To raise implement, pull lift lever backward to the RAISE position. After implement is raised, allow lift lever to move to the TRANSPORT position. Normally, implement should be raised when driving from one work area to another, except when descending steep slopes.

Caution

Do not leave lever in unlocked position.

The exposed, rotating blades of the cutting unit or other implements are hazardous.

Never raise a cutting unit or implement while the blades or other components are rotating.

Page 28

Figure 29

1. Lift lever

PTO Lever

The PTO lever (Fig. 30) has two positions: ON (engage) and OFF (disengage). Slowly push PTO lever fully forward to ON position to start the implement or cutting unit blades. Slowly, pull lever backward to OFF position to stop implement operation. The only time PTO lever should be in the ON position is when implement or cutting unit is down in operating position.

Fuel Gauge

The fuel gauge (Fig. 30) indicates quantity of fuel remaining in fuel tank.

Temperature Gauge

The temperature gauge (Fig. 30) registers the temperature of the coolant in the cooling system. If temperature of coolant gets too high the engine will shut off automatically.

Hour Meter

The hour meter (Fig. 30) registers accumulated hours of engine operation.

Oil Pressure Warning Light

The oil pressure warning light (Fig. 30) glows when oil pressure in engine drops below a safe level. If low oil pressure ever occurs, stop engine and determine the cause. Repair the damage before starting the engine again.

Charge Indicator

Illuminates when system charging circuit malfunctions (Fig. 30).

Engine Coolant Temperature Warning Light

The light illuminates and engine shuts down when coolant reaches a excessively high temperature (Fig. 30).

Temperature Override Switch

Press and hold override switch to start engine after high temperature shut down. Use only for emergency operation.

Glow Plug Indicator

When lit, indicates glow plugs are on (Fig. 30).

Key Switch

Three positions: OFF, ON / Preheat and START (Fig. 30).

Throttle Control

The throttle (Fig. 30) is used to operate engine at various speeds. Moving throttle forward increases engine speed—FAST; backward decreases engine speed—SLOW. The throttle regulates the speed of the cutter blades or other implement components and, in conjunction with traction pedal, controls ground speed of the traction unit.

Page 29

Seat Adjusting Lever

To adjust standard seat, push lever (Fig. 31) backward and slide seat to the desired position. Release lever to lock seat in place. The suspension seat may be adjusted forward or rearward by pulling out the lever at the left side of the seat, sliding the seat to the desired position, and releasing the lever. The weight adjustment knob may be adjusted for any operator’s comfort.

Note: Move throttle to 1/2 throttle position when restarting a warm engine.

5. When engine is started for the first time, or after engine oil change, or overhaul of engine, transmission or axle, operate the machine in forward and reverse for one to two minutes. Also operate the lift lever and PTO lever to assure proper operation of all parts. Turn power steering wheel to the left and right to check steering response. Then shut engine off and check fluid levels, check for oil leaks, loose parts and any other noticeable malfunctions.

Caution

• Shut engine off and wait for all moving parts to

stop before checking for oil leaks, loose parts or other malfunctions.

Starting/Stopping Engine

Important The fuel system must be bled if any of the

following situation have occurred.

A. Initial start up of a new machine.

B. Engine has ceased running due to lack of fuel.

C. Maintenance has been performed upon fuel system components; i.e., filter replaced, separator serviced, etc.

Refer to Bleeding The Fuel System.

1. Ensure parking brake is set, PTO switch is in OFF

position and lift lever is in TRANSPORT or FLOAT position. Remove foot from traction pedal and insure it is in neutral.

2. Move throttle control to 1/2 throttle position.

3. Turn ignition switch to ON / Preheat position. An

automatic timer will control preheat for 10 seconds. After preheat, turn key to START position. CRANK ENGINE FOR NO LONGER THAN 15 SECONDS. Release key when engine starts. If additional preheat is required, turn key to OFF position then to ON / preheat position. Repeat process as required.

4. Run engine at idle speed or partial throttle until engine warms up.

6. To stop engine, move throttle control backward to SLOW position, move PTO switch to OFF position and rotate ignition key to OFF. Remove key from switch to prevent accidental starting.

Bleeding Fuel System

1. Park the machine on a level surface. Make sure fuel tank is at least half full.

2. Unlatch and raise hood.

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.

3. Open the air bleed screw on the fuel injection pump

(Fig. 32).

Page 30

1. Drive the machine slowly to a large, relatively open area. Lower cutting unit, stop the engine and apply parking brake.

2. Sit on seat. Move PTO lever to ON position. With the traction pedal in neutral position, try to start the engine. The engine should not crank. If the engine cranks, there is a malfunction in the interlock system that should be corrected before beginning operation.

Figure 32

1. Fuel injection pump bleed screw

4. Turn key in ignition switch to the ON position. Electric fuel pump will begin operation, thereby forcing air out around air bleed screw. Leave key in ON position until solid stream of fuel flows out around screw. Tighten screw and turn key to OFF.

Note: Normally, engine should start after above bleeding procedures are followed. However, if engine does not start, air may be trapped between injection pump and injectors; refer to Bleeding Air From Injectors.

Checking the Interlock Switches

Caution

3. Sit on seat. Move PTO lever to OFF and depress the traction pedal. Try to start the engine. The engine should not crank. If the engine cranks, there is a malfunction in the interlock system that should be corrected before beginning operation.

Warning

Do not operate the machine without an implement unless the PTO drive shaft is also removed.

4. Sit on seat and start the engine. Disengage the parking

brake. Raise off the seat and move the PTO lever to ON. The engine should stop within 2–3 seconds. If the engine does not stop, there is a malfunction in the interlock system that should be corrected before beginning operation.

5. Engage the parking brake. Depress the traction pedal while engine is running and the PTO lever is disengaged. The engine should stop within 2 seconds. If engine stops, the switch is operating correctly; thus, continue operation. If engine does not stop, there is a malfunction in the interlock system that should be corrected before beginning operation.

If 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 machine has interlock switches in the electrical system. These switches are designed to stop the engine when operator gets off the seat while either the PTO lever is engaged or traction pedal is depressed. However, operator may get off the seat while engine is running. Although engine will continue to run if PTO lever is disengaged and traction pedal is released, it is strongly recommended that the engine be stopped before dismounting from the seat.

To check operation of interlock switches:

Pushing or Towing the Traction Unit

In an emergency, the traction unit can be pushed or towed for a very short distance. However, Toro does not recommend this as standard procedure.

Important Do no push or tow the traction unit faster

than 2 to 3 MPH (3 to 4.8 km/h) because transmission may be damaged. If traction unit must be moved a considerable distance, transport it on a truck or trailer. Whenever traction unit is pushed or towed, bypass valve must be open.

1. Reach under traction unit and rotate bypass valve (Fig. 33) 1/2 to 1 turn counterclockwise. Opening the valve opens an internal passage in the transmission, thereby bypassing transmission oil. Because fluid is bypassed, traction unit can be moved without damaging the transmission.

Page 31

1. Bypass valve

Another characteristic to consider is the operation of the turning pedals that are connected to the brakes. The brakes

Figure 33

can be used to assist in turning the machine. However, use them carefully, especially on soft or wet grass because the turf may be torn accidentally. Another benefit of the turning brakes is to maintain traction. For example: in some slope conditions, the uphill wheel slips and loses traction. If this situation occurs, depress uphill turn pedal gradually and intermittently until the uphill wheel stops slipping, thus, increasing traction on the downhill wheel.

Use extra care when operating machine on slopes. Always have seat pivot retaining pin installed. Drive slowly and avoid sharp turns on slopes to prevent roll overs. The cutting deck must be lowered when going downhill for steering control.

2. Before starting engine, close bypass valve by rotating it clockwise until it is securely seated. Do not exceed 5 to 8 ft.-lb. (7 to 11 N⋅m). Do not start engine when valve is open.

Important Running the machine with bypass valve

open will cause the transmission to overheat.

Operating Characteristics

Practice driving the machine because it has a hydrostatic transmission and its characteristics are different than many turf maintenance machines. Some points to consider when operating the traction unit, cutting unit, or other implement are the transmission, engine speed, load on the cutting blades or other implement components, and the importance of the brakes.

To maintain enough power for the traction unit and implement while operating, regulate traction pedal to keep engine rpm high and somewhat constant. A good rule to follow is: decrease ground speed as the load on the implement increases, and increase ground speed as the load decreases.

Therefore, allow traction pedal to move backward as engine rpm decrease, and depress pedal slowly as rpm increase. By comparison, when driving from one work area to another—with no load and cutting unit raised—have throttle in FAST position and depress traction pedal slowly but fully to attain maximum ground speed.

The grass deflector must always be installed and in lowest position on the side discharge cutting unit.

Warning

Careless operation, combined with terrain angle, ricochets, or improperly positioned safety guards can lead to thrown object injuries.

A person or pet may suddenly appear in or near the mowing area.

Stop mowing and do not resume mowing until the area is cleared.

Before stopping the engine, disengage all controls and move throttle to SLOW. Moving throttle to SLOW reduces high engine rpm, noise, and vibration. Turn key to OFF to stop engine.

4. Dirt injection port

Figure 41

2. Remove the cover from the air cleaner body. Before removing the filter, use low pressure air (40 psi, clean and dry) to help remove large accumulations of debris packed between outside of primary filter and the canister. Avoid using high pressure air which could

Page 36

force dirt through the filter into the intake tract. This cleaning process prevents debris from migrating into the intake when the primary filter is removed.

3. Remove and replace the primary filter (Fig. 44). Cleaning of the used element is not recommended due to the possibility of damage to the filter media. Inspect the new filter for shipping damage, checking the sealing end of the filter and the body. Do not use a damaged element. Insert the new filter by applying pressure to the outer rim of the element to seat it in the canister. Do not apply pressure to the flexible center of the filter.

4. Clean the dirt ejection port located in the removable cover (Fig. 43). Remove the rubber outlet valve from the cover, clean the cavity and replace the outlet valve.

Changing Engine Oil And Filter

Check oil level after each day’s operation or each time machine is used. Change oil and filter initially after first 50 hours of operation; change oil and filter after every 100 hours of operation thereafter. If possible, run engine just before changing oil because warm oil flows better and carries more contaminants than cold oil.

1. Position machine on a level surface.

2. Open the hood. Set drain pan under the oil pan and in

line with drain plug (Fig. 45).

5. Repeat steps on remaining nozzles.

Cleaning Radiator And Screen

To prevent the engine from overheating, the screen and radiator must be kept clean. Normally, check the screen and radiator daily and, if necessary, clean any debris off these parts. However, it will be necessary to check and clean the screen and radiator frequently in extremely dusty and dirty conditions.

Note: If engine shuts off due to overheating, first check the radiator and screen for excessive buildup of debris.

To thoroughly clean the radiator:

1. Remove the screen.

2. Working from the fan side of the radiator, either spray

the radiator with a water hose or blow with compressed air.

When filling the radiator, level of coolant must be above the core and 1 inch (25 mm) below bottom of filler neck. DO NOT OVERFILL. Always install radiator cap (Fig. 51) securely.

Adjusting the Traction Drive for Neutral

1. Park vehicle on a level surface and turn engine off. Apply the parking brake, tip seat forward, and actuate pump lever (Fig. 59) to ensure assembly is properly seated and operating freely. Correct any discrepancy.

6. Because the wheel is rotating, the pump plate must be adjusted. But before adjusting the pump plate, move throttle to SLOW. If wheel is rotating forward, loosen capscrews, and lightly tap bottom of pump plate counterclockwise (Fig. 59). By contrast, tap pump plate clockwise if wheel is rotating backward (Fig. 59). When wheel stops rotating, tighten capscrews holding pump plate against side of transmission. Verify the adjustment with throttle in SLOW and FAST position.

7. Should front wheel continue to rotate, check for the following:

• Ball bearing is loose or worn out (Fig. 59).

• Plunger on interlock switch is sticking.

• Loose or missing fasteners

• Worn bolt securing pump lever to transmission

• Pump lever loose on control shaft. (Correct by

applying Loctite 680 to shaft.)

• Weak or damaged leaf springs (Fig. 59). Replace.

• Internal transmission component malfunction.

Contact your local Toro distributor for assistance.

Adjusting the Rear Wheel Bearings

(Models 30626 & 30630 only)

1. Jack up rear of machine until wheel is off shop floor. Use jack stands or block the machine to prevent it from accidentally falling.

2. Remove dust cap from end of wheel spindle. Also remove cotter pin securing retainer (Fig. 67).

3. Tighten the jam nut (Fig. 67) to approximately 75–100 in–lbs using a hand wrench.

4. Turn the wheel hub to seat the bearings.

5. Loosen the jam nut until it is away from the flatwasher

and the wheel hub has end play.

6. Tighten the jam nut to 15–20 in–lbs while rotating the the wheel hub.

7. Place the nut retainer over the jam nut. If the cotter pin hole is not aligned with the retainer slot, remove the retainer nut and reorientate until alignment occurs.

8. Insert cotter pin. The wheel hub must not have any free play.

9. Install dust cap on end of wheel spindle.

10. Remove jack stands and lower machine to shop floor.

Adjusting the Brakes

Adjust the service brakes when there is more than 1 in. (25 mm) of “free travel” of the turn pedals, or when the brakes do not work effectively. Free travel is the distance the brake pedal moves before braking resistance is felt.

The brakes should only need adjusting after considerable use. These periodic adjustments can be performed where the brake cables connect to the brake pedal mount. When the cables are no longer adjustable, the star nut on the inside of the brake drum must be adjusted to move the brake shoes outward. However, the brake cables must be adjusted again to compensate for this adjustment.

Page 45

1. To reduce free travel of turn pedals—tighten the brakes—loosen front nut on threaded end of brake cable (Fig. 68). Then tighten rear nut to move cable backward until turn pedals have 1/2 to 1 in. (13 to 25 mm) of free travel. Tighten front nut after brakes are adjusted correctly.

Figure 69

1. Slot

Figure 68

1. Jam nuts

2. When adjustment of brake cable cannot get free travel within 1/2 to 1 in. (13 to 25 mm), the star nut inside the brake drum must be adjusted. However, before adjusting the star nut, loosen brake cable nuts to prevent unnecessary strain on the cables.

3. Loosen five wheel nuts holding wheel and tire assembly on wheel studs.

4. Jack up machine until front wheel is off the shop floor. Use jack stands or block the machine to prevent it from falling accidentally.

5. Remove wheel nuts and slide wheel and tire assembly off studs. Rotate brake drum until adjusting slot is at bottom and centered over star nut that adjusts brake shoes (Fig. 69).

6. Using a brake adjusting tool or screwdriver, rotate star nut (Fig. 69) down until brake drum (Fig. 70) locks because of outward pressure of brake shoes (Fig. 70).

Figure 70

1. Star nut 2. Brake shoes

7. Loosen star nut about 12 to 15 notches or until brake drum rotates freely.

8. Install wheel and tire assembly on studs with five wheel nuts. Tighten nuts to 45-55 ft–lb (61-75 Nm).

9. Remove jack stands or blocking and lower machine to the shop floor.

10. Adjust the brake cables using step 1.

5. Shut engine off and check level of hydraulic system; refer to Checking the Hydraulic System Oil, page 25.

Changing the Hydraulic System Fluid

The hydraulic system fluid must be changed after every 1000 hours of normal operation or every two years, whichever comes first.

The recommended replacement fluid is:

1. Start engine, park machine on a level surface, lower implement to the shop floor, set the parking brake, and shut engine off. Block the two rear wheels.

2. Jack up both sides of front axle and support it with jack stands.

3. Clean area around hydraulic fluid filter and remove filter.

4. Remove drain plug from fitting between axle housing and oil filter and allow fluid to flow into drain pan (Fig. 72).

6. Add Mobil Fluid 424 until lubricant level is up to hole

in clutch. Clutch should be approximately 1/3 full.

7. Install check plug.

Note: Do not use engine oil (i.e. 10W30) in bidirectional

clutch. Anti–wear and extreme pressure additives will cause undesirable clutch performance.

Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after

handling.

Important Before welding on the machine, disconnect

ground cable from the battery to prevent damage to the electrical system.

Note: Check battery condition weekly or after every 50 hours of operation. Keep terminals and entire battery case clean because a dirty battery will discharge slowly. To clean the battery, wash the entire case with solution of baking soda and water. Rinse with clear water. Coat the battery posts and cable connectors with Grafo 112X (skin-over) grease (Toro Part No. 505-47) or petroleum jelly to prevent corrosion.
