Understanding the Diagnostic Light

4-Wheel Drive Machines Only

The machine comes with a diagnostic light that indicates if the electronic controller senses an electronic malfunction. The diagnostic light is located on the control panel (Figure 10). When the electronic controller is functioning correctly and the key switch is moved 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, the light turns on steady until you change the 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 when the fault has been resolved.

g014333

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

  • An output has been shorted.

  • An output has an open circuit.

Use the diagnostic ace display to determine which output is malfunctioning.

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

  • The light is burned out.

  • The fuses are blown.

  • The electronic controller 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.

Diagnostic Ace Display

The machine comes with an electronic controller which controls most of the machine functions. The controller determines what function is required for various input switches (e.g., seat switch and key switch) 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 tool and the overlay to help verify and correct electrical functions of the machine. Contact your authorized Toro distributor for assistance.

    • Check the area that you will be mowing and never fold down a folding roll bar in areas where there are slopes, drop-offs, or water.

    Additional ROPS Safety for Machines with a Cab or a Fixed Roll Bar

    • A cab installed by Toro is a roll bar.

    • Always wear your seat belt.

    Slope Safety

    • Slopes are a major factor related to loss of control and rollover accidents, which can result in severe injury or death. You are responsible for safe slope operation. Operating the machine on any slope requires extra caution.

    • Evaluate the site conditions to determine if the slope is safe for machine operation, including surveying the site. Always use common sense and good judgment when performing this survey.

    • Review the slope instructions listed below for operating the machine on slopes and to determine whether you can operate the machine in the conditions on that day and at that site. Changes in the terrain can result in a change in slope operation for the machine.

    • Avoid starting, stopping, or turning the machine on slopes. Avoid making sudden changes in speed or direction. Make turns slowly and gradually.

    • Do not operate a machine under any conditions where traction, steering, or stability is in question.

    • Remove or mark obstructions such as ditches, holes, ruts, bumps, rocks, or other hidden hazards. Tall grass can hide obstructions. Uneven terrain could overturn the machine.

    • Be aware that operating the machine on wet grass, across slopes, or downhill may cause the machine to lose traction. Loss of traction to the drive wheels may result in sliding and a loss of braking and steering.

    • Use extreme caution when operating the machine near drop-offs, ditches, embankments, water hazards, or other hazards. The machine could suddenly roll over if a wheel goes over the edge or the edge caves in. Establish a safety area between the machine and any hazard.

    • Identify hazards at the base of the slope. If there are hazards, mow the slope with a pedestrian-controlled machine.

    • If possible, keep the cutting unit(s) lowered to the ground while operating on slopes. Raising the cutting unit(s) while operating on slopes can cause the machine to become unstable.

    • Use extreme caution with grass-collection systems or other attachments. These can change the stability of the machine and cause a loss of control.

    Using the Rollover-Protection System (ROPS)

    Warning

    A rollover accident can cause injury or death.

    • Keep the roll bar in the raised locked position.

    • Use the seat belt.

    • Ensure that the seat plate is secured with the seat latch.

    Warning

    You have no rollover protection when the roll bar is in the down position.

    • Lower the roll bar only when necessary.

    • Do not wear the seat belt when the roll bar is in the down position.

    • Drive slowly and carefully.

    • Raise the roll bar as soon as clearance permits.

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

    Raising the Roll Bar

    Important: Always use the seat belt when the roll bar is in the raised and locked position.

    1. Ensure that the seat is secured with the seat latch.

    1. If the engine is cold, allow the engine to warm up 5 to 10 minutes before engaging the PTO.

    2. While seated in the seat, ensure that the traction pedal is in the NEUTRAL position and that the engine is at full throttle.

    3. Pull up the PTO switch to engage it (Figure 25).

      g014178

    Disengaging the PTO

    To disengage, push the PTO switch to the OFF position.

    Operating Tips

    Using the Fast Throttle Setting

    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.

    Selecting the Ground Speed

    To improve cut quality, use a slower ground speed. Decrease the ground speed as the load on the cutting blades increases, and increase ground speed as the load on the blades decreases.

    Alternating Mowing Direction

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

    Avoiding a Low Cut

    If the machine cutting width is wider than the machine that you previously used, raise the cutting height to ensure that uneven turf is not cut too short.

    Select the Proper Height-of-Cut Setting to Suit Conditions

    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 need to slow down the forward speed and/or raise the height-of-cut to the next higher setting.

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

    Cutting Long Grass

    If you allow the grass to grow slightly longer than normal, or if the grass contains a high degree of moisture, raise the cutting height to a higher setting and cut the grass at this setting. Then cut the grass again using the lower, normal setting.

    Keeping the Mower Clean

    Clean clippings and dirt from the underside of the mower after each use. If grass and dirt build up inside the mower, cutting quality eventually becomes 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.

    Maintaining the Blades

    • Maintain sharp blades throughout the cutting season. Sharp blades create a clean cut without tearing or shredding the grass blades. Tearing and shredding causes grass to turn 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 the cutting unit Operator’s Manual for instructions to replace the blade.

    After Operation

    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, mufflers, and engine compartment to help prevent fires. Clean up oil or fuel spills.

    • If the cutting units are in the transport position, use the positive mechanical lock (if available) before you leave the machine unattended.

    • Allow the engine to cool before storing the machine in any enclosure.

    • Remove the key and shut off the fuel (if equipped) before storing or hauling the machine.

    • 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.

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

    Pushing the Machine by Hand

    If the machine stalls or runs out of fuel, you may need to push it. You must first open both of the hydraulic bypass valves.

    Important: Always push the machine by hand and never a long distance. Never tow the machine, because damage to the hydraulic system may occur.

    2. Lift the seat.

    3. Rotate each bypass valve counterclockwise 1 turn (Figure 26).

      Note: This allows hydraulic fluid to bypass the pump, enabling the wheels to turn.

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

    4. Disengage the parking brake before pushing the machine.

    Changing to Machine Operation

    1. Rotate each bypass valve clockwise 1 turn and hand tighten them (Figure 26).

      Note: Do not overtighten the bypass valves.

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

    Servicing the Air Cleaner

    Maintenance Service IntervalMaintenance Procedure
    Every 400 hours
  • Service the air cleaner. (Service the air cleaner earlier if the air-cleaner indicator shows red. Service it more frequently in extremely dirty or dusty conditions.)
  • Check the air-cleaner body for damage that could cause an air leak. Replace a damaged air cleaner. Check the whole intake system for leaks, damage, or loose hose clamps.

    Service the air-cleaner filter only when the service indicator (Figure 31) requires it. Changing the air filter before it is necessary only increases the chance of dirt entering the engine when you remove the filter.

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

    1. Release the latch securing the air-cleaner cover to the air-cleaner body (Figure 31).

      g014183
    2. Remove the cover from the air-cleaner body. Before removing the filter, use clear and dry low-pressure air (276 kPa or 40 psi) 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.

      Note: This cleaning process prevents debris from migrating into the intake when you remove the filter.

    3. Remove and replace the filter.

      Important: Do not clean the used element to prevent damaging 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.

    • Charge the battery in an open, well-ventilated area, away from sparks and flames. Unplug the charger before connecting or disconnecting the battery. Wear protective clothing and use insulated tools.

    Servicing the Battery

    Maintenance Service IntervalMaintenance Procedure
    Every 50 hours
  • Check battery cable connections.
  • 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 the temperature is 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. Connect the cables, positive (+) cable first, and coat the terminals with petroleum jelly.

    Warning

    Battery terminals or metal tools could short against metal machine components causing sparks. Sparks can cause the battery gasses to explode, resulting in personal injury.

    • When removing or installing the battery, do not allow the battery terminals to touch any metal parts of the machine.

    • Do not allow metal tools to short between the battery terminals and metal parts of the machine.

    Warning

    Incorrect battery cable routing could damage the machine 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.

    Checking the Fuses

    If the machine stops or has other electrical-system issues, check the fuses. Grasp each fuse in turn and remove them 1 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 1 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 38).

    g014186

    The cab fuses are located in the fuse box on the cab headliner (Figure 39).

    g028467

    Storing the Battery

    If you store the machine for 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 you store it 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, ensure that it is fully charged. The specific gravity of a fully charged battery is 1.265 to 1.299.

    Diagnostic Ace Display

    The machine comes with an electronic controller which controls most of the machine functions. The controller determines what function is required for various input switches (e.g., seat switch and key switch) 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 tool and overlay to help verify and correct electrical functions of the machine. Contact your Toro Distributor for assistance.

    Checking the Interlock Switches

    The interlock switches prevent the engine from cranking or starting unless the traction pedal is in the NEUTRAL position and the PTO is disengaged. The engine should stop when you press the traction pedal when you are not sitting on 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 attachment, shut off the engine, and engage the parking brake.

    2. Raise the seat.

    3. Locate the wire harness and connectors near the controller (Figure 40).

      g018321
    4. Connect the Diagnostic ACE display tool connector to the diagnostic connector (Figure 41).

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

      g004140
    5. Turn the key switch to the ON position, but do not start the engine.

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

    6. 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 the Diagnostic ACE to change it to “inputs displayed.”

      The Diagnostic ACE will illuminate the LED associated with each of the inputs when you close that input switch.

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

    8. 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 switch with an ohm meter. Replace all switches and repair wiring that are not functioning.

    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 the source of the malfunction.

    Verifying the Output Function

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

    2. Raise the seat.

    3. Locate wire harness and connectors near the controller.

    4. Carefully unplug the loopback connector from the harness connector.

    5. Connect the Diagnostic ACE connector to the appropriate harness connector. If the machine comes with a front attachment, it will have 2 controllers.

      Note: Ensure 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 engine.

      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 the Diagnostic ACE to change it to “inputs displayed.”

      Note: You may need 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. Do this as often as necessary; 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 the 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 needed.

    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 Toro Distributor for assistance.

    Important: Do not leave the Diagnostic ACE display connected to the machine. It is not designed to withstand the environment of the everyday use of the machine. After using the Diagnostic ACE, disconnect it from the machine and connect the loop-back connector to the wire-harness connector. The machine cannot operate without the loopback connector installed on the wire harness. Store the Diagnostic ACE in dry, secure location in the shop, not on the machine.

    Drive System Maintenance

    Checking the Tire Pressure

    Maintenance Service IntervalMaintenance Procedure
