    You can adjust the counterbalance on the lift arms of the rear cutting units to compensate for different turf conditions and to maintain a uniform height of cut in rough conditions or in areas of thatch buildup.

    You can adjust each counterbalance spring to 1 of 4 settings. Each increment increases or decreases counterbalance on the cutting unit by 2.3 kg (5 lb). You can position the springs on the back side of the first spring actuator to remove all counterbalance (fourth position).

    1. Park the machine on a level surface, lower the cutting units, engage the parking brake, shut off the engine, and remove the key from the ignition switch.

    2. Insert a tube or similar object onto the long spring end to relieve the spring tension during the adjustment (Figure 34).

      Caution

      The springs are under tension and could cause personal injury.

      Use caution when adjusting them.

    3. While relieving the spring tension, remove the bolt and locknut securing the spring actuator to the bracket (Figure 34).

      g034346
    4. Move the spring actuator to the desired hole location and secure it with the bolt and the locknut.

    5. Repeat the procedure on the remaining spring.

    Bleeding the Fuel System

    1. Park the machine on a level surface, lower the cutting units, engage the parking brake, shut off the engine, and remove the key.

    2. Ensure that the fuel tank is at least half full.

    3. Unlatch and raise the hood.

    4. Open the air-bleed screw on the fuel-injection pump (Figure 35).

      g008891
    5. Turn the key in the ignition switch to the ON position. The electric fuel pump will begin operation, thereby forcing air out around the air-bleed screw.

      Note: Leave the key in the ON position until a solid stream of fuel flows out around the screw.

    6. Tighten the screw and turn the ignition key to OFF.

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

    Understanding the Diagnostic Light

    The machine is equipped with a diagnostic light that indicates if the electronic controller senses an electronic malfunction. The diagnostic light is located on the control panel (Figure 36). When the electronic controller is functioning correctly and you move the key switch to the ON position, the controller diagnostic light turns on for 3 seconds and turn off to indicate that the light is working properly. If the engine shuts off, then the light turns on steady until the you change key position. The light blinks if the controller detects a malfunction in the electrical system. The light stops blinking and automatically resets when you turn the key switch to the OFF position once the fault has been resolved.

    g020251

    When the controller diagnostic light blinks, 1 of the following problems has been detected by the controller:

    • An output has been shorted.

    • An output is open circuited.

    Using the diagnostic display, determine which output is malfunctioning; refer to Checking the Interlock Switches.

    If the diagnostic light is not illuminated when the key switch is in the ON position, this indicates that the electronic controller is not operating. Possible causes are as follows:

    • The loop-back is not connected.

    • The light is burned out.

    • Fuses are blown.

    • It is not functioning correctly.

      Check the electrical connections, input fuses, and diagnostic light bulb to determine the malfunction. Ensure that the loop-back connector is secured to the wire harness connector.

    Understanding the Diagnostic ACE Display

    The machine is equipped with an electronic controller which controls most machine functions. The controller determines what function is required for various input switches (i.e., seat switch, key switch, etc.) and turns on the outputs to actuate solenoids or relays for the requested machine function.

    For the electronic controller to control the machine as desired, each of the input switches, output solenoids, and relays must be connected and functioning properly.

    Use the Diagnostic ACE display to help verify and correct electrical functions of the machine.

    Checking the Interlock Switches

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Check the interlock system.
  • The purpose of the interlock switches is to prevent the engine from cranking or starting unless the traction pedal is in the NEUTRAL position, the Enable/Disable switch is in the DISABLE position, and the Lower Mow/Raise control is in the NEUTRAL position. In addition, the engine should shut off when you press the traction pedal with no one in the seat or if the parking brake is engaged.

    Caution

    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.

    Verifying the Interlock Switch Function

    1. Park the machine on a level surface, lower the cutting units, engage the parking brake, and shut off the engine.

    2. Remove the cover from the control panel.

    3. Locate the wire harness and loop-back connector (Figure 37).

      g020260
    4. Carefully unplug the loop-back connector from the harness connector.

    5. Connect the Diagnostic ACE display connector to the harness connector (Figure 38).

      Note: Ensure that the correct overlay decal is positioned on the Diagnostic ACE display.

      g004140
    6. Turn the key switch to the ON position, but do not start the machine.

      Note: The red text on the overlay decal refers to input switches and the green text refers to outputs.

    7. The “inputs displayed” LED, on the lower right column of the Diagnostic ACE, should be illuminated. If the “outputs displayed” LED is illuminated, press the toggle button, on Diagnostic ACE, to change LED to “inputs displayed.”

      The Diagnostic ACE illuminates the LED associated with each of the inputs when that input switch is closed.

    8. Individually, change each of the switches from open to closed (i.e., sit on the seat, engage the traction pedal, etc.), and note that the appropriate LED on the Diagnostic ACE blinks on and off when the corresponding switch is closed. Repeat this for all switches that you can change by hand.

    9. If a switch is closed and the appropriate LED does not turn on, check all wiring and connections to the switch and/or check the switches with an ohm meter or multimeter. Replace any malfunctioning switches and repair any malfunctioning wiring.

      Note: The Diagnostic ACE also has the ability to detect which output solenoids or relays are turned on. This is a quick way to determine if a machine malfunction is electrical or hydraulic.

    Verifying Output Function

    1. Park the machine on a level surface, lower the cutting units, engage the parking brake, shut off the engine, and remove the key.

    2. Remove the access panel from the side of the control arm.

    3. Locate the wire harness and connectors near the controller.

    4. Carefully unplug the loop-back connector from the harness connector.

    5. Connect the Diagnostic ACE connector to the harness connector.

      Note: Make sure that the correct overlay decal is positioned on the Diagnostic ACE.

    6. Turn the key switch to the ON position, but do not start the machine.

      Note: The red text on the overlay decal refers to input switches and the green text refers to outputs.

    7. The “outputs displayed” LED, on lower right column of Diagnostic ACE, should be illuminated. If the “inputs displayed” LED is illuminated, press the toggle button, on the Diagnostic ACE, to change the LED to “outputs displayed”.

      Note: It may be necessary to toggle between “inputs displayed” and “outputs displayed” several times to do the following step. To toggle back and forth, press the toggle button once. This may be done as often as required. Do not hold the button.

    8. Sit on the seat and attempt to operate the desired function of the machine. The appropriate output LEDs should illuminate to indicate that the ECM is turning on that function.

      Note: If the correct output LEDs do not illuminate, verify that the required input switches are in the necessary positions to allow that function to occur. Verify correct switch function. If the output LEDs are on as specified, but the machine does not function properly, this indicates a non-electrical problem. Repair as necessary.

      Note: If each output switch is in the correct position and functioning correctly, but the output LEDs are not correctly illuminated, this indicates an ECM problem. If this occurs, contact your authorized Toro distributor for assistance.

      Important: The Diagnostic ACE display must not be left connected to the machine. It is not designed to withstand the environment of the everyday use of the machine. When you are finished using the Diagnostic ACE, disconnect it from the machine and connect the loop-back connector to the harness connector. The machine does not operate without the loop-back connector installed on the harness. Store the Diagnostic ACE in a dry, secure location in the shop, not on the machine.

    Operating Tips

    Becoming Familiar with the Machine

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

    Understanding the Warning System

    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.

    Mowing Grass

    Start the engine and move the throttle to the FAST position. Move the Enable/Disable switch to the ENABLE position and use the Lower Mow/Raise lever 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.

    Driving the Machine in Transport Mode

    Move the Enable/Disable switch to the DISABLE position and raise the cutting units to the transport position. Move the Mow/Transport lever to the TRANSPORT position. Be careful when driving between objects so that you do not accidentally damage the machine or the cutting units. Use extra care when operating the machine on slopes. Drive slowly and avoid sharp turns on slopes to prevent rollovers.

    After Operation

    After Operation Safety

    General Safety

    • Shut off the engine, remove the key, and wait for all movement to stop before you leave the operator’s position. Allow the machine to cool before adjusting, servicing, cleaning, or storing it.

    • Clean grass and debris from the cutting units, drives, mufflers, cooling screens, and engine compartment to help prevent fires. Clean up oil or fuel spills.

    • Disengage the drive to the attachment whenever you are hauling or not using the machine.

    • Maintain and clean the seat belt(s) as necessary.

    • Do not 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.

    Pushing or Towing the Machine

    In an emergency, you can move the machine by actuating the bypass valve in the variable displacement hydraulic pump and installing a hydraulic hose to bypass the check valve, and then pushing or towing the machine.

    Important: Do not push or tow the machine faster than 3 to 4.8 km/h (2 to 3 mph) or for more than 0.4 km (1/4 mile), because internal transmission damage may occur. The bypass valve must be open whenever you push or tow the machine. Additionally, you need to install a hydraulic hose to bypass the check valve whenever you push or tow the machine in reverse.

    If you need to push or tow your machine, you will likely need to move it both forward and in reverse. To ensure that the drive system does not become damaged from pushing or towing, it is best to prepare the machine for both forward and reverse pushing or towing.

    Preparing the Machine for Pushing or Towing in Reverse

    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:

    • Toro Part No. 59-7410, diagnostic fitting

    • Toro Part No. 354-79, diagnostic-fitting cap

    • Toro Part No. 95-8843, hydraulic hose

    • Toro Part No. 95-0985, coupler fitting (2)

    • Toro Part No. 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 39).

      g033131
    2. Connect a hydraulic hose between the diagnostic fitting installed in the rear traction manifold and the reverse traction pressure test port (Figure 40).

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

      g033132
    3. Rotate the bypass valve 90° (1/4 turn) in either direction to open it and allow fluid to bypass internally (Figure 41).

      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.

      g009703
    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.

    Pushing or Towing the Machine Forward Only

    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 41).

      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.

    Hauling the Machine

    • Use full-width ramps for loading the machine onto a trailer or truck.

    • Tie the machine down securely.

    Engine Maintenance

    Engine Safety

    • Shut off the engine before checking the oil or adding oil to the crankcase.

    • Do not change the governor speed or overspeed the engine.

    Checking the Engine-Oil Level

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Check the engine-oil level.
  • 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 3.8 L (4 US qt) 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 0ºF (-17ºC))

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

    Note: Toro Premium Engine Oil is available from your distributor in either 15W-40 or 10W-30 viscosity.

    Note: The best time to check the engine oil is when the engine is cool before it has been started for the day. If it has already been run, allow the oil to drain back down to the sump for at least 10 minutes before checking. If the oil level is at or below the Add mark on the dipstick, add oil to bring the oil level to the Full mark. Do not overfill the engine. If the oil level is between the Full and Add marks, no oil addition is required.

    1. Park the machine on a level surface, lower the cutting units, engage the parking brake, shut off the engine, and remove the key.

  • Park the machine on a level surface, lower the cutting units, engage the parking brake, shut off the engine, and remove the key from the ignition switch.

    Maintain the battery electrolyte level and keep the top of the battery clean. Store the machine where the temperature is cooler rather than warmer to prevent the battery from discharging more rapidly.

    Maintain the cell level with distilled or demineralized water. Do not fill the cells above the bottom of the split ring inside each cell. Install the filler caps with the vents pointing to the rear (toward the fuel tank).

    Danger

    Battery electrolyte contains sulfuric acid which is fatal if consumed and causes severe burns.

    • Do not drink electrolyte and avoid contact with skin, eyes, or clothing. Wear eye protection to shield your eyes and rubber gloves to protect your hands.

    • Fill the battery where clean water is always available for flushing the skin.

    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. Do not remove the filler caps while cleaning.

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

    Warning

    Incorrect battery cable routing could damage the tractor and cables causing sparks. Sparks can cause the battery gasses to explode, resulting in personal injury.

    • Always disconnect the negative (black) battery cable before disconnecting the positive (red) cable.

    • Always connect the positive (red) battery cable before connecting the negative (black) cable.
