• 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 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 people and damage to property.

• While mowing, always wear appropriate clothing, including eye protection, substantial, slip-resistant footwear, long trousers, and ear protection.

• Tie back long hair. Do not wear jewelry.

• 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.

• 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 the operator's presence controls, safety switches and shields are attached and functioning properly. Do not operate unless they are functioning properly.

• To avoid personal injury or property damage, use extreme care in handling fuel. Fuel 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.

• 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.

• 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;

  • Do not turn sharply. Use care when reversing.

  • 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 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 over-speed 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 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 cylinders/reels if not mowing.

• Do not operate the machine when ill, tired, or 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.

• 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.

• Keep all fasteners tight to be sure that 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 risk of fire, keep the engine, silencer/muffler, battery compartment and fuel storage area free of grass, leaves, or excessive grease. Clean up oil or fuel spillage.

• 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-cylinder/multi-reel machines, take care as rotating one cylinder/reel can cause other cylinders/reels to rotate.

• Disengage drives, lower the cutting units, set parking brake, stop engine and remove key from ignition. Wait for all movement to stop before adjusting, cleaning or repairing.

• Use jack stands to support components when required.

• Carefully release pressure from components with stored energy.

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

• Use care when checking the cylinders/reels. 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.

• 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

Pull out on the lever to slide the seat fore or aft (Figure 31).

Rotate the knob to adjust the seat armrest angle (Figure 31).

Move the lever to adjust the seat back angle (Figure 31).

Adjust for operator weight (Figure 31). Pull up on the lever to increase the air pressure and push down to decrease the air pressure. The proper adjustment is attained when the weight gauge is in the green region.

Important: Bleed the fuel system if any of the following situations have occurred:

• The engine has ceased running due to lack of fuel.

• Maintenance has been performed upon the fuel system components.

1. Remove your foot from the traction pedal and ensure that the pedal is in the NEUTRAL position.

   Note: Ensure that the parking brake is set.

2. Move the engine-speed switch to the low idle position.

3. Turn the ignition key to the RUN position.

   Note: The glow indicator will light.

4. When the glow indicator dims, turn the ignition key to the Start position.

5. Release the key immediately when the engine starts and allow it to return to the Run position.

6. Adjust the engine speed.

   Important: Do not run the starter motor more than 15 seconds at a time or premature starter failure may result. If the engine fails to start after 15 seconds, turn the key to the Off position, recheck the controls and procedures, wait 15 additional seconds, and repeat the starting procedure.

   When the temperature is less than -7°C (20°F), the starter motor can be run for 30 seconds on then 60 seconds off for 2 attempts.

   Caution

   Contact with moving parts could cause injury.

   Shut the engine off and wait for all moving parts to stop before checking for oil leaks, loose parts, and other malfunctions.

Important: Allow the engine to idle for 5 minutes before shutting it off after a full-load operation. This allows the turbocharger to cool down before shutting the engine off. Failure to do so may lead to turbocharger trouble.

Note: Lower the cutting units to the ground whenever you park the machine. This relieves the hydraulic load from the system, prevents wear on system parts, and also prevents accidental lowering of the cutting units.

1. Return the engine speed to low idle.

2. Move the PTO switch to the OFF position.

3. Set the parking brake.

4. Rotate the ignition key to OFF.

5. Remove the key from the switch to prevent accidental starting.

Important: If you need to push or tow the machine in reverse, you must first bypass the check valve in the 4-wheel-drive manifold.

The following Toro parts are needed to bypass the check valve:

• 59-7410, diagnostic fitting

• 354-79, diagnostic-fitting cap

• 95-8843, hydraulic hose

• 95-0985, coupler fitting (2)

• 340-77, hydraulic fitting (2)

1. Install a diagnostic fitting in the unmarked port located between ports M8 and P2 on the rear traction manifold (Figure 42).

   

   Figure 42

   1. Rear traction manifold (behind front left wheel)
   2. Unmarked port

2. Connect a hydraulic hose between the diagnostic fitting installed in the rear traction manifold and the reverse traction pressure test port (Figure 43).

   Note: Use the hydraulic fittings and coupler fittings as needed to install the hose.

   

   Figure 43

   1. Reverse traction pressure test port
   2. Hydraulic fluid return filter

3. Rotate the bypass valve 90° (1/4 turn) in either direction to open it and allow fluid to bypass internally (Figure 44).

   Note: Because the fluid bypasses the transmission, you can move the machine slowly without damaging the transmission.Note the position of the valve when opening and closing it.

   

   Figure 44

   1. Bypass valve

4. When you are finished pushing or towing the machine, remove the hydraulic hose that you installed.

5. Install the existing cap onto the reverse traction pressure test port.

6. Install the diagnostic-fitting cap onto the fitting that you installed on the manifold.

7. Rotate the bypass valve 90° (1/4 turn) back before starting the engine.

   Note: Do not exceed 7 to 11 N·m (5 to 8 ft-lb) torque to close the valve.

If you need to push or tow the machine forward only, you can just rotate the bypass valve.

Important: If you need to push or tow the machine in reverse, refer to Preparing the Machine for Pushing or Towing in Reverse.

1. Open the hood and remove the center shroud.

2. Rotate the bypass valve 90° (1/4 turn) in either direction to open it and allow fluid to bypass internally (Figure 44).

   Note: Because the fluid bypasses the transmission, you can move the machine forward slowly without damaging the transmission.Note the position of the valve when opening and closing it.

3. Rotate the bypass valve 90° (1/4 turn) back before starting the engine.

   Note: Do not exceed 7 to 11 N·m (5 to 8 ft-lb) torque to close the valve.

Before mowing grass, practice operating the machine in an open area. Start and stop the engine. Operate in forward and reverse. Lower and raise the cutting units and engage and disengage the reels. When you feel familiar with the machine, practice operating up and down slopes at different speeds.

If a warning light comes on during operation, stop the machine immediately and correct the problem before continuing operation. Serious damage could occur if you operate the machine with a malfunction.

Start the engine and move the engine speed switch to the FAST position. Move the Mow Speed Limiter to the MOW position. Move the PTO switch to the ON position and use the Lift Switch to control the cutting units (the front cutting units are timed to lower before the rear cutting units). To move forward and cut grass, press the traction pedal forward.

Move the PTO switch to the Off position and raise the cutting units to the transport position. Move the Mow Speed Limiter to the transport position. Be careful when driving between objects so that you do not accidentally damage the machine or cutting units. Use extra care when operating the machine on slopes. Drive slowly and avoid sharp turns on slopes to prevent rollovers. Lower the cutting units when going downhill for steering control.

1. Release the hood latches (Figure 46) and pivot open the hood.

   

   Figure 46

   1. Hood latch (2)

2. Remove the cotter pins securing the rear hood brackets to the frame pins and lift off the hood.

The machine has grease fittings that must be lubricated regularly with No. 2 lithium grease. If the machine is operated under normal conditions, lubricate all bearings and bushings after every 50 hours of operation or immediately after every washing.

The grease fitting locations and quantities are as follows:

• Brake shaft pivot bearings (5) (Figure 47)

   3. Cover

2. Remove the cover from the air-cleaner body.

3. Before removing the filter, use low-pressure air—275 kPa (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 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.

4. Remove and replace the primary filter (Figure 54).

   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.

2. Clean the screen thoroughly of all debris.

   Note: To remove the screen, lift off the hinge pins.

3. Clean both sides of the oil cooler/radiator area (Figure 75) thoroughly with compressed air. Start from the front and blow the debris out toward the back. Then clean from the back side and blow toward the front. Repeat the procedure several times until all chaff and debris is removed.

   

   Figure 75

   1. Oil cooler/radiator

   Important: Cleaning the oil cooler/radiator with water will promote premature corrosion damage to components and compact debris.

4. Close the rear screen and secure it with the latch.

Adjust the service brakes when there is more than 13 mm (1/2 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 braking resistance is felt.

1. Disengage the locking latch from the brake pedals so that both pedals work independently of each other.

2. To reduce free travel of the brake pedals, tighten the brakes as follows:

   1. Loosen the front nut on the threaded end of the brake cable (Figure 76).

      

      Figure 76

      1. Brake cable

   2. Tighten the rear nut to move the cable backward until the brake pedals have 0 to 13 mm (0 to 1/2 inch) of free travel.

      Note: Make sure that there is no brake tension when the pedal is released.

   3. Tighten the front nuts after the brakes are adjusted correctly.

Check the condition and tension of the belts (Figure 77) after every 100 operating hours.

1. Proper tension will allow 10 mm (3/8 inch) deflection when a force of 45 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 77).

   

   Figure 77

   2. Mounting bolt

3. Increase or decrease the tension of the alternator belt and tighten the bolts.

4. Check the deflection of the belt again to ensure that the tension is correct.

Change the hydraulic fluid after every 800 operating hours, in normal conditions. If the fluid becomes contaminated, contact your local Toro distributor because the system must be flushed. Contaminated fluid looks milky or black when compared to clean fluid.

1. Shut off the engine and raise the hood.

2. Disconnect the case return line from the bottom of the reservoir and let the hydraulic fluid flow into a large drain pan.

3. Connect the line when the hydraulic fluid stops draining.

4. Fill the reservoir with approximately 28.4 L (7.5 US gallons) of hydraulic fluid; refer to Checking the Level of the Hydraulic Fluid.

   Important: Use only the hydraulic fluids specified. Other fluids could cause system damage.

5. Install the reservoir cap.

6. Start the engine and use all of the hydraulic controls to distribute hydraulic fluid throughout the system.

7. Check for leaks and stop the engine.

8. Check the fluid level and add enough to raise the level to the Full mark on the dipstick.

   Note: Do not overfill the hydraulic system.

Change the 2 hydraulic filters initially after the first 200 operating hours. Thereafter, change the filters after every 800 operating hours, in normal conditions.

Use Toro replacement filters Part No. 94-2621 for the rear (cutting unit) of the machine and 75-1310 for the front (charge) of the machine.

Important: Use of any other filter may void the warranty on some components.

1. Position the machine on a level surface, lower the cutting units, stop the engine, engage the parking brakes, and remove the ignition key.

2. Clean the area around the filter mounting area.

3. Place a drain pan under the filter and remove the filter (Figure 78 and Figure 79).

4. Lubricate the new filter gasket and fill the filter with hydraulic fluid.

5. Ensure that the filter mounting area is clean.

6. Screw the filter on until the gasket contacts the mounting plate; then tighten the filter an additional 1/2 turn.

7. Start the engine and let it run for about 2 minutes to purge air from the system.

8. Stop the engine and check for leaks.

Inspect the hydraulic lines and hoses daily for leaks, kinked lines, loose mounting supports, wear, loose fittings, weather deterioration, and chemical deterioration. Make all necessary repairs before operating.

Note: When backlapping, the front units all operate together, and the rear units operate together.

1. Position the machine on a level surface, lower the cutting units, stop the engine, engage the parking brake, and move the PTO switch to the OFF position.

2. Unlock and raise the hood to expose the controls.

3. Make the initial reel-to-bedknife adjustments appropriate for backlapping on all cutting units which are to be backlapped; refer to the cutting unit Operator's Manual.

4. Select either front, rear, or both backlap levers to determine which units to backlap (Figure 80).

5. Start the engine and run it at low idle speed.

   Danger

   Changing the engine speed while backlapping may cause the reels to stall.

   • Never change the engine speed while backlapping.

   • Only backlap at low idle engine speed.

   Danger

   Contact with a moving cutting unit could cause personal injury.

   To avoid personal injury, be certain that you are clear of the cutting units before proceeding.

6. With the mow-speed limiter in the mow position, move the PTO switch to the ON position. Press the Lift Switch to start the backlapping operation on the designated reels.

7. Apply lapping compound with a long-handled brush.

   Note: Never use a short-handled brush.

8. If the reels stall or become erratic while backlapping, increase the throttle speed until the reel stabilizes.

9. To make an adjustment to the cutting units while backlapping, turn the reels off by pressing the rear of the lift switch; move the PTO switch to the OFF position, and shut off the engine. After completing the adjustments, repeat steps 4 through 8.

10. Repeat the procedure for all cutting units that you want to backlap.

11. When finished, return the backlap levers to the Mow position, lower the hood, and wash all lapping compound off of the cutting units. Adjust the cutting unit reel-to-bedknife contact as needed. Move the cutting-unit reel speed controls to the desired mowing position.

    Important: If the backlap switch is not returned to the Off position after backlapping, the cutting units will not raise or function properly.

    Note: Additional instructions and procedures on backlapping are available in the Toro Sharpening Reel & Rotary Mowers Manual, Form No. 80-300SL.

    Note: For a better cutting edge, run a file across the front face of the bedknife after lapping. This will remove any burrs or rough edges that may have built up on the cutting edge.
