• Read the Operator's Manual and other training material carefully. Be familiar with the controls, safety signs, and the proper use of the equipment.

• Never allow children or people unfamiliar with these instructions to use the lawn machine. Local regulations can 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 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 brake. 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 load distribution.

• While mowing, always wear substantial footwear and long trousers. 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.

• Replace faulty silencers/mufflers.

• Before using, always visually inspect to see that the blades, blade bolts and cutter assembly are not worn or damaged. Replace worn or damaged blades and bolts in sets to preserve balance.

• To avoid personal injury or property damage, use extreme care in handling gasoline. Gasoline is extremely flammable and the vapors are explosive.

• Extinguish all cigarettes, cigars, pipes, and other sources of ignition.

• Use only an approved fuel container.

• Never remove fuel cap or add fuel with the engine running.

• Allow engine to cool before refueling.

• Never refuel the machine indoors.

• Never store the machine or fuel container where there is an open flame, spark, or pilot light such as on a water heater or on other appliances.

• Never fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers on the ground away from your vehicle before filling.

• Remove equipment from the truck or trailer and refuel it on the ground. If this is not possible, then refuel such equipment with a portable container, rather than from a fuel dispenser nozzle.

• Keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock open device.

• If fuel is spilled on clothing, change clothing immediately.

• Never overfill fuel tank. Replace fuel cap and tighten securely.

• Be alert, slow down and use caution when making turns. Look behind and to the side before changing directions.

• 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 and shift into neutral.

• 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 on a slope;

  • use slow speeds on slopes and during tight turns;

  • stay alert for humps and hollows 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.

• 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:

  • disengage the power take-off and lower the attachments;

  • set the parking brake;

  • stop the engine and remove the key.

• Disengage drive to attachments, stop the engine, and remove the ignition key:

  • before clearing blockages or unclogging chute;

  • before checking, cleaning or working on the machine;

  • after striking a foreign object. Inspect the machine for damage and make repairs before restarting and operating the equipment;

  • if the machine starts to vibrate abnormally (check immediately).

• Do not operate the machine under the influence of alcohol or drugs.

• Lightning can cause severe injury or death. If lightning is seen or thunder is heard in the area, do not operate the machine; seek shelter.

• Disengage drive to attachments when transporting or not in use.

• Stop the engine and disengage drive to attachment before refueling.

• The ROPS is an integral and effective safety device. Keep a folding ROPS in the raised and locked position and use the seat belt when operating the machine.

• Lower a folding ROPS temporarily only when absolutely necessary. Do not wear the seat belt when folded down.

• Be aware there is no rollover protection when a folded ROPS is in the down position.

• Be certain that the seat belt can be released quickly in the event of an emergency.

• Check the area to be mowed and never fold down a folding ROPS in areas where there are slopes, drop offs or water.

• Check carefully for overhead clearances (i.e. branches, doorways, electrical wires) before driving under any objects and do not contact them.

• Keep the ROPS in safe operating condition by periodically thoroughly inspecting for damage and keeping all mounting fasteners tight.

• Replace a damaged ROPS. Do not repair or revise.

• Do not remove the ROPS.

• Any alterations to a ROPS must be approved by the manufacturer.

• 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.

• Replace worn or damaged parts for safety.

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

• On multi-bladed machines, take care as manually rotating one blade can cause other blades to rotate.

• When machine is to be parked, stored or left unattended, lower the mower deck.

• Use care when loading or unloading the machine into a trailer or truck.

• Use full width ramps for loading machine into trailer or truck.

• Tie the machine down securely using straps, chains, cable, or ropes. Both front and rear straps should be directed down and outward from the machine

Fuel tank capacity: 51.1 L (13.5 US gallons)

Important: Use only ultra-low sulphur diesel fuel. Fuel with higher rates of sulfur degrades the diesel oxidation catalyst (DOC), which causes operational problems and shortens the service life of engine components.Failure to observe the following cautions may damage the engine.

• Never use kerosene or gasoline instead of diesel fuel.

• Never mix kerosene or used engine oil with the diesel fuel.

• Never keep fuel in containers with zinc plating on the inside.

• Do not use fuel additives.

• Over time, the DPF accumulates soot in the soot filter. The computer for the engine monitors the soot level in the DPF.

• When enough soot accumulates, the computer informs you that it is time to regenerate the diesel particulate filter.

• DPF regeneration is a process that heats the DPF to convert the soot to ash.

• In addition to the warning messages, the computer reduces the power produced by the engine at different soot-accumulation levels.

Engine Warning Messages—Soot Accumulation

Indication Level	Fault Code	Engine Power Rating	Recommended Action
Level 1: Engine Warning	Figure 13 Check EngineSPN 3719, FMI 16	The computer de-rates the engine power to 85%	Perform a parked regeneration as soon as possible; refer to Parked Regeneration.
Level 2: Engine Warning	Figure 14 Check EngineSPN 3719, FMI 0	The computer de-rates the engine power to 50%	Perform a recovery regeneration as soon as possible; refer to Recovery Regeneration.

• The lighter ash is discharged through the exhaust system; the heavier ash collects in the soot filter.

• Ash is a residue of the regeneration process. Over time, the diesel particulate filter accumulates ash that does not discharge with the engine exhaust.

• The computer for the engine calculates the amount of ash accumulated in the DPF.

• When enough ash accumulates, the engine computer sends information to the InfoCenter in the form of a system advisory or an engine fault to indicate the accumulation of ash in the DPF.

• The advisory and faults are indications that it is time to service the DPF.

• In addition to the warnings, the computer reduces the power produced by the engine at different ash-accumulation levels.

1. Disengage the power take off (PTO), turn the ignition key to off and apply the parking brake.

2. Remove the key from the ignition switch. Both by-pass valves must be opened.

3. Lift the seat.

4. Rotate each by-pass valve counterclockwise 1 turn (Figure 43).

   This allows hydraulic fluid to by-pass the pump enabling the wheels to turn.

   Important: Do not rotate the by-pass valves more than 1 turn. This prevents valves from coming out of the body and causing fluid to run out.

5. Disengage the parking brake before pushing.

Rotate each by-pass valve clockwise 1 turn and hand tighten them (torque of approximately 8 N-m [71 in-lb]) (Figure 43).

Note: Do not over tighten the by-pass valves.

The machine will not drive unless the by-pass valves are turned in.

Figure 43

1. By-pass valves

To maintain enough power for the machine and deck while mowing, operate the engine at the fast throttle position and adjust your ground speed for conditions. A good rule to follow is: decrease ground speed as the load on the cutting blades increases; and increase ground speed as load on the blades decreases.

Alternate mowing direction to avoid making ruts in the turf over time. This also helps disperse clippings which enhances decomposition and fertilization.

To improve cut quality, use a slower ground speed.

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.

Remove approximately 25 mm (1 inch) or no more than 1/3 of the grass blade when cutting. In exceptionally lush and dense grass, you may have to slow down the forward speed and/or raise the height-of-cut to the next higher setting.

Important: If cutting more than 1/3 of the grass blade off, or in sparse long grass or dry conditions, the use of flat sail blades is recommended to reduce air-borne chaff, debris, and deck drive component strain.

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.

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 unsatisfactory.

To reduce the risk of fire hazard, keep the engine, muffler, battery compartment, parking brake, cutting units, and fuel storage compartment free of grass, leaves, or excessive grease. Clean up any spilled oil or fuel.

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 blades daily for sharpness, and for any wear or damage. Sharpen the blades as necessary. If a blade is damaged or worn, replace it immediately with a genuine Toro replacement blade. Refer to Servicing the Cutting Blades.

1. Release the hood latches.

2. Lift up on the hood until the prop rod can be positioned behind the frame tube (Figure 47).

3. Lower the hood until the rod is in front of and resting against the frame tube.

4. To lower the hood, raise the hood until the prop rod can be raised above the frame tube, then lower the hood.

5. Secure the hood latches

The machine has grease fittings that must be lubricated regularly with No. 2 General Purpose Lithium Base Grease. If the machine is operated under normal conditions, lubricate all bearings and bushings after every 50 hours of operation. Bearings and bushings must be lubricated daily when operating conditions are extremely dusty and dirty. Dusty and dirty operating conditions could cause dirt to get into the bearings and bushings, resulting in accelerated wear. Lubricate the grease fittings immediately after every washing, regardless of interval specified.

1. Wipe the grease fittings clean so foreign matter cannot be forced into the bearing or bushing.

2. Pump grease into the fittings.

3. Wipe off excess grease.

Note: To access the rear steering linkage grease fittings, the storage compartment needs to be removed.

Note: Jack the machine off the floor to allow better grease migration through both the upper and lower king pin bushings. Grease must be observed purging out of both the top and the bottom of the axle casting/bushing assembly areas of all four kingpin assemblies.

Figure 48

Note: Bearing life can be negatively affected by improper wash down procedures. Do not wash down the unit when it is still hot and avoid directing high-pressure or high volume spray at the bearings or seals.

Check the air cleaner body for damage which could cause an air leak. Replace if damaged. Check the whole intake system for leaks, damage or loose hose clamps.

Service the air cleaner filter only when the service indicator (Figure 49) requires it. Changing the air filter before it is necessary only increases the chance of dirt entering the engine when the filter is removed.

Important: Be sure the cover is seated correctly and seals with the air cleaner body.

1. Pull the latch outward and rotate the air cleaner cover counter-clockwise (Figure 49).

   

   Figure 49

   1. Air cleaner service indicator
   2. Air cleaner cover latch
   3. Air cleaner cover

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 the filter and the canister. Avoid using high pressure air which could force dirt through the filter into the intake tract.

   This cleaning process prevents debris from migrating into the intake when the filter is removed.

3. Remove and replace the filter (Figure 50).

   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.

   

   Figure 50

   1. Air cleaner filter

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

5. Install the cover orienting the rubber outlet valve in a downward position—between approximately 5:00 to 7:00 when viewed from the end.

6. Secure the latch.

  1. Refer to the Engine section in the Service Manual for information on disassembling and assembling the diesel-oxidation catalyst and the soot filter of the DPF.

  2. Refer to your Authorized Toro Distributor for diesel-oxidation catalyst and the soot filter replacement parts or service.

  3. Contact your Authorized Toro Distributor to have them reset the engine ECU after you install a clean DPF.

Drain water or other contaminants from water separator (Figure 55) daily. Replace filter canister after every 400 hours of operation.

1. Place a clean container under the fuel filter.

2. Loosen the drain plug on the bottom of the filter canister and open the vent on the top of the canister mount.

   

   Figure 55

   1. Water separator filter canister

3. Clean the area where the filter canister mounts.

4. Remove the filter canister and clean the mounting surface.

5. Lubricate the gasket on the filter canister with clean oil.

6. Install the filter canister by hand until the gasket contacts mounting surface, then rotate it an additional 1/2 turn.

7. Tighten the drain plug on the bottom of the filter canister and close the vent on the top of the canister mount.

The engine fuel filter should be replaced after every 400 hours of operation.

1. Clean the area around the fuel filter head (Figure 56).

   

   Figure 56

   1. Fuel Filter head
   2. Fuel Filter

2. Remove the filter and clean the filter head mounting surface (Figure 56).

3. Lubricate the filter gasket with clean lubricating engine oil. Refer to the Engine Operator's Manual, included with the machine, for additional information.

4. Install the dry filter canister, by hand, until the gasket contacts the filter head, then rotate it an additional 1/2 turn.

5. Start the engine and check for fuel leaks around the filter head.

Check the fuel lines and connections every 400 hours or yearly, whichever comes first. Inspect them for deterioration, damage, or loose connections.

The fuel pick-up tube, located inside the fuel tank, is equipped with a screen to help prevent debris from entering the fuel system. Remove the fuel pick-up tube and clean screen as required.

If the machine stops or has other electrical system issues, check the fuses. Grasp each fuse in turn and remove them one at a time, checking to see if any are blown. If you need to replace a fuse, always use the same type and amperage rated fuse as the one you are replacing, otherwise you could damage the electrical system (refer to the decal next to the fuses for a diagram of each fuse and its amperage).

The traction unit fuses are located under the seat (Figure 57).

Keep the top of the battery clean. If you store the machine in a location where temperatures are extremely high, the battery will run down more rapidly than if the machine is stored in a location where temperatures are cool.

Keep the top of the battery clean by washing it periodically with a brush dipped in ammonia or bicarbonate of soda solution. Flush the top surface with water after cleaning it. Do not remove the fill caps while cleaning the battery.

The battery cables must be tight on the terminals to provide good electrical contact.

If corrosion occurs at the terminals, disconnect the cables, negative (-) cable first, and scrape the clamps and terminals separately. Reconnect the cables, positive (+) cable first, and coat the terminals with petroleum jelly.

If the machine will be stored more than 30 days, remove the battery and charge it fully. Either store it on a shelf or on the machine. Leave the cables disconnected if it is stored on the machine. Store the battery in a cool atmosphere to avoid quick deterioration of the charge in the battery. To prevent the battery from freezing, make sure it is fully charged. The specific gravity of a fully charged battery is 1.265-1.299.

Check the pressure after every 50 operating hours or monthly, whichever occurs first.

Maintain the air pressure in the front and rear tires. The correct air pressure is 172 kPa (25 psi) in the rear tires and 103 kPa (15 psi) in the front tires. If a cab is installed on the machine, the front and rear tires should be inflated to 172 kPa (25 psi). Uneven tire pressure can cause uneven cut. Check the tires when they are cold to get the most accurate pressure reading.

1. Press the steering selector switch to the rearward (four wheels steer) position (Figure 58).

   

   Figure 58

   1. Steering selector switch

2. On a paved or dirt surface, turn the steering wheel to the left or right and continue turning until all 4 wheels have stopped turning. Automatic synchronization of wheel alignment should occur.

   Important: Doing this procedure on turf can result in turf damage directly under each of the turning tires.

The cooling system is filled with a 50/50 solution of water and permanent ethylene glycol anti freeze. Check the level of the coolant in the expansion tank at the beginning of each day before starting the engine. The capacity of the cooling system is 7.5 liters (6 quarts).

1. Check the level of the coolant in the expansion tank (Figure 59). The coolant level should be between the marks on the side of the tank.

2. If coolant level is low, remove the expansion tank cap and replenish the system. Do not overfill.

3. Install the expansion tank cap.

   

   Figure 59

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

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

Clean the radiator as follows:

1. Open the hood and secure the prop rod.

2. Loosen the flange nut securing the clean out cover to the underside of the rear frame (Figure 60). Rotate the cover to the side to expose the clean out hole in the frame.

   

   Figure 60

   1. Clean out cover

3. Working from the fan side of the radiator, blow out debris with low pressure (50 psi) compressed air (do not use water). Repeat the step from the front of the radiator and again from the fan side.

4. After the radiator is thoroughly cleaned, clean out debris that may have collected in the channel at the radiator base and around the frame. Also, clean out the engine compartment and brake linkage to assure optimum performance.

5. Close the clean out cover and secure the flange nut.

6. Close the hood.

Adjust the service brakes when there is more than 25 mm (1 inch) of free travel of the brake pedal, or when the brakes do not work effectively. Free travel is the distance the brake pedal moves before you feel braking resistance.

Note: Use the wheel motor backlash to rock the drums back and forth to ensure that the drums are free prior to and after adjustment.

1. To reduce free travel of the brake pedals, tighten the brakes by loosening the front nut on the threaded end of the brake cable (Figure 61).

   

   Figure 61

   1. Brake cables
   2. Front nuts

2. Tighten the rear nut to move the cable backward until brake pedals have 1.27 to 1.9 cm (1/2 to 3/4 inch) of free travel, before wheel lock up is achieved.

3. Tighten the front nuts, ensuring that both cables actuate the brakes simultaneously.

If the parking brake fails to engage, an adjustment to the brake pawl is required.

1. Loosen the 2 screws securing the parking brake pawl to the frame (Figure 62).

   

   Figure 62

   1. Brake cables
   2. Screws (2)
   3. Parking brake pawl
   4. Brake detent

2. Press the parking brake pedal forward until the brake detent completely engages on the brake pawl (Figure 62).

3. Tighten the 2 screws locking the adjustment.

4. Press the brake pedal to release the parking brake.

5. Check the adjustment and readjust as required.

Check the condition and tension of the belt (Figure 63) after every 100 operating hours.

1. Proper tension will allow 10 mm (3/8 inch) deflection when a force of 44 N (10 lb) is applied on the belt midway between the pulleys.

2. If the deflection is not 10 mm (3/8 inch), loosen the alternator mounting bolts (Figure 63). Increase or decrease the alternator belt tension and tighten the bolts. Check the deflection of the belt again to ensure that the tension is correct.

   

   Figure 63

   2. Alternator

Note: If the machine has recently had the hydraulic oil changed or the traction motors or hoses replaced, any air trapped in the system will have to be worked out prior to performing this procedure. This can be accomplished by operating the machine in forward and reverse for a few minutes and then replenishing the oil as required.

When positioned on a level surface, the machine must not creep when the traction pedal is released. If it does creep, adjust as follows:

1. Park the machine on a level surface, stop the engine, and lower the cutting unit to the floor.

2. Jack up the rear of the machine until the rear tires are off the shop floor. Support the machine with jack stands to prevent it from falling accidentally.

   Note: On 4 wheel drive models, the front tires must also be off the shop floor and supported by jack stands.

   Warning

   The engine must be running so this adjustment can be performed. This could cause personal injury.

   Keep hands, feet, face, and other body parts away from any hot parts of the engine and any rotating parts.

3. Start the engine, set the throttle to the Slow position and observe which direction the rear tires rotate.

   Important: Make sure that the traction pedal is in the neutral position.

   • If the left rear tire is rotating, loosen the jam nuts on the left side transmission control rod (Figure 64).

     Note: The forward end of the control rod has a left hand thread. The rear end of the rod, which is connected to the transmission, has a right hand thread.

     

     Figure 64

     1. Transmission control rods

   • If the left rear tire is rotating in reverse, lengthen the rod by slowly turning the rod counter-clockwise (as viewed from the front) until the left rear tire stops rotating or minimal rotation is detected in reverse

   • If the left rear tire is rotating forward, shorten the rod by slowly turning the rod clockwise (as viewed from the front) until the left rear tire stops rotating.

4. Move the throttle to the Fast position. Make sure the wheel remains stopped or minimal creep is detected in reverse. Adjust as required.

5. Tighten the jam nuts.

6. Repeat the procedure for the right rear tire, if required, by using the right side transmission control rod .

7. Stop the engine. Remove the jack stands and lower the machine to the shop floor.

8. Test drive the machine to make sure it does not creep.

1. Disengage the PTO, release the traction pedal to the neutral position and set the parking brake.

2. Move the throttle lever to the Slow position, stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.

3. Loosen the jam nut on the stop bolt for the traction pedal (Figure 65).

   1. Traction pedal
   2. Stop bolt w/ jam nut (forward)
   3. 1.5 mm (0.060 inch)
   4. Stop bolt w/ jam nut (reverse)

4. Adjust the stop bolt all the way in (away from the traction pedal).

5. Using your hand, push the traction pedal all the way forward, with light pressure, until it stops and hold it there. Maintain only light pressure on the pedal when pushing it to the full forward position.

6. With the seat in the raised position, verify that you are not over loading the linkage by making sure the transmission does not move when the pedal is depressed to the stop.

7. Adjust the stop bolt out (towards the traction pedal) until there is a gap of 1.5 mm (0.060 inch) between the head of the stop bolt and the bottom of the traction pedal.

8. Tighten the jam nut to secure the stop bolt in place.

9. The reverse stop bolt may be adjusted if the maximum reverse speed is not acceptable. For a faster reverse speed, adjust the stop bolt in. For a slower reverse speed, adjust the stop bolt out.

The mow speed limiter lever (Figure 66) can be flipped forward to limit the traction speed while operating.

1. Disengage the PTO, release the traction pedal to the neutral position and set the parking brake.

2. Move the throttle lever to the Slow position, stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.

3. Loosen the jam nut on the mow speed limiter stop bolt (Figure 66).

   

   Figure 66

   2. Stop bolt w/ jam nut

4. Thread the stop bolt in to increase the mow speed and out to decrease the mow speed.

5. Tighten the jam nut to lock the adjustment.

6. Rotate the mow speed limiter lever down, operate the machine to verify the adjustment and readjust the stop bolt as required.

Check the level of the hydraulic fluid before the engine is first started and daily thereafter.

1. Position the machine on a level surface. Release the traction pedal to the neutral position and start the engine. Run engine at lowest possible RPM to purge the system of air. Do not engage the PTO. Raise the deck to extend lift cylinders, stop the engine, and remove the key.

2. Remove the hydraulic fill cap (Figure 67) from filler neck.

3. Remove the dipstick and wipe it with a clean rag (Figure 67).

4. Screw the dipstick all the way into the filler neck; then remove it and check level of fluid (Figure 67).

   If level is not within notched area of the dipstick, add enough high quality hydraulic fluid to raise level to within the notched area. Do not overfill.

5. Replace the dipstick and thread the fill cap finger-tight onto filler neck.

6. Check all hoses and fittings for leaks.
