Toro 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 standards.

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.

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.

Preparation

Be sure to establish your own special procedures and work rules for unusual operating conditions (e.g., slopes too steep for operation). Survey the complete mowing site to determine which hills can be safely operated on. When performing this site survey, always use common sense and take into consideration the turf condition and the rollover risk. To determine which hills or slopes may be safely operated on, use the slope chart provided in the manual. To perform a site survey, follow the procedure outlined in the Operation section of the this manual. The maximum side hill angle is detailed on the slope decal affixed on the machine.

Training

The operator must be skilled and trained in how to drive on hillsides. Failure to use caution on slopes or hills may cause the vehicle to tip or roll, possibly resulting in personal injury or death.

Operation

  • Know how to stop the machine and 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.

  • Keep hands, feet, and clothing away from moving parts and the mower discharge area.

  • Fill the fuel tank until level is 1/2 inch (12 mm) below the bottom of the filler neck. Do not overfill.

  • Check the safety interlock switches daily for proper operation. If a switch should fail, replace the switch before operating the machine.

  • When starting the engine, engage the parking brake, put the traction pedal in neutral, and disengage the blade drive. After the engine starts, release the parking brake and keep your foot off of the traction pedal. The machine must not move. If movement is evident, refer to the Maintenance section of this manual to adjust the traction drive.

  • Use extreme caution when operating close to sand traps, ditches, creeks, steep hillsides, or other hazards.

  • Reduce speed when making sharp turns.

  • Do not turn on hills.

  • Do not operate on a side hill that is too steep. A rollover may occur before losing traction.

  • The slope angle at which the machines will tip is dependent on many factors. Among these are mowing conditions such as wet or undulating terrain, speed (especially in turns), position of the cutting units (up or down), tire pressure, and operator experience. At side hill angles of 20 degrees or less, the risk of a rollover is low. As the slope angle increases to a recommended maximum limit of 25 degrees, the risk of a rollover increases to a moderate level. Do not exceed a 25 degree side hill slope angle because the risk of a rollover and serious injury or death is very high.

  • For steering control, lower the cutting units when going down slopes.

  • Avoid sudden stops and starts.

  • Use the reverse pedal for braking.

  • Watch for traffic when near or crossing roads. Always yield the right-of-way.

  • Raise the cutting units when driving from one work area to another.

  • Do not touch the engine, muffler, exhaust pipe, or hydraulic tank while the engine is running or soon after it has stopped because these areas could be hot enough to cause burns.

  • 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.

Maintenance and Storage

  • Before servicing or making adjustments, stop the engine and remove the ignition key.

  • Ensure that the entire machine is properly maintained and in good operating condition. Frequently check all nuts, bolts, screws, and hydraulic fittings.

  • 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. If fluid is injected into the skin it must be surgically removed within a few hours by a doctor familiar with this form of injury or gangrene may result.

  • 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 to the ground.

  • 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. Keep everyone away.

  • Do not overspeed the engine by changing governor settings. To ensure safety and accuracy, have an Authorized Toro Distributor check the maximum engine speed with a tachometer.

  • The engine must be shut off before checking the oil or adding oil to the crankcase.

  • If major repairs are ever needed or if assistance is desired, contact an Authorized Toro Distributor.

  • To ensure optimum performance and continued safety certification of the machine, use only genuine Toro replacement parts and accessories. Replacement parts and accessories made by other manufacturers could be dangerous, and such use could void the product warranty.

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. Refer to the parts catalog for part numbers.

    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. Position the machine on a level surface.

    2. Remove the dipstick (Figure 24) and wipe it with a clean rag.

      g008881
    3. Push the dipstick down into the dipstick tube and make sure that it is seated fully. Pull the dipstick out and check the oil level.

    4. If the oil level is low, remove the oil-fill cap (Figure 25) and gradually add small quantities of oil, checking the level frequently, until the level reaches the Full mark on the dipstick.

      g008882
    5. Install the oil-fill cap and close the hood.

    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.

    The fuel tank capacity is approximately 42 liters (11 US gallons).

    Use summer-grade diesel fuel (Number 2-D) at temperatures above -7°C (20°F) and winter-grade diesel fuel (Number 1-D or Number 1-D/2-D blend) below -7°C (20°F ). 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 -7 degrees C (20 degrees F) will contribute toward longer fuel pump life and increased power compared to winter grade fuel.

    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.

    • Painted surfaces may be damaged by biodiesel blends.

    • 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.

    • Contact your distributor if you wish for more information on biodiesel

    1. Clean the area around the fuel-tank cap (Figure 26).

    2. Remove the fuel tank cap.

    3. Fill the tank to the bottom of the filler neck. Do not overfill the tank. Install the cap.

    4. To prevent a fire hazard, wipe up any fuel that may have spilled.

      g008884

      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 6 to 13 mm (1/4 to 1/2 inch) 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.

    Checking the Cooling System

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Check the engine-coolant level.
  • Clean debris off of the radiator/oil cooler daily (Figure 27). Clean the radiator/oil cooler hourly if conditions are extremely dusty and dirty; refer to Cleaning the Engine Cooling System.

    g019984

    The cooling system is filled with a 50/50 solution of water and permanent ethylene glycol anti-freeze. Check the coolant level at the beginning of each day before starting the engine.

    The capacity of the cooling system is approximately 5.7 L (6 US qt).

    Caution

    • Do not open the radiator cap when the engine is running.

    • Use a rag when opening the radiator cap, and open the cap slowly to allow steam to escape.

    1. Check the coolant level in the expansion tank (Figure 28). With a cold engine, the coolant level should be approximately midway between the marks on the side of the tank.

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

    3. Install the expansion-tank cap.

      g008885

    Checking the Hydraulic System

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Check the hydraulic-fluid level.
  • The reservoir is filled at the factory with approximately 13.2 liters (3.5 US gallons) of high-quality hydraulic fluid. The best time to check the hydraulic oil is when the fluid is cold. The machine should be in its transport configuration. If the oil level is below the ‘add’ mark on the dipstick, add oil to bring the oil level to the middle of the acceptable range. Do not overfill the reservoir. If the oil level is between the ‘full’ and the ‘add’ marks, no oil addition is required.

    The recommended replacement fluid is:

    Toro Premium All Season Hydraulic Fluid

    (available in 19 liter (5 gallon) containers or 208 liter (55 gallon) drums—see the parts documentation or your Toro distributor for part numbers)

    Alternative fluids: If the Toro fluid is not available, other conventional, petroleum-based fluids may be used, provided that they meet all of the following material properties and industry specifications. Check with your oil supplier to see whether the oil meets these specifications.

    Starting and Stopping the Engine

    You may need to bleed the fuel system if any of the following situations have occurred (refer to Bleeding the Fuel System):

    • Initial start up of a new engine

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

    • Maintenance has been performed upon the fuel system components; i.e. filter replaced, etc.

    Starting the Engine

    1. Be sure that the parking brake is set and the cutting unit drive switch is in the Disengage position.

    2. Remove your foot from the traction pedal and make sure that the pedal is in the neutral position.

    3. Move the throttle lever to the 1/2 throttle position.

    4. Insert the key into the switch and rotate it to the On/Preheat position until the glow-plug indicator light goes out (approximately 7 seconds); then rotate the key to the Start position to engage the starter motor.

      Note: Release the key when the engine starts. The key will move automatically to the On/Run position.

      Important: To prevent overheating of the starter motor, do not engage the starter longer than 15 seconds. After 10 seconds of continuous cranking, wait 60 seconds before engaging the starter motor again.

    5. When the engine is started for the first time or after an overhaul of the engine, operate the machine in forward and reverse for 1 to 2 minutes. Also operate the lift lever and cutting unit drive switch to be sure of proper operation of all parts.

      Turn the steering wheel to the left and right to check steering response; then shut the engine off and check for oil leaks, loose parts, and any other noticeable malfunctions.

      Caution

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

    Stopping the Engine

    Move the throttle control to the Idle position, move the cutting unit drive switch to Disengage, and rotate the starter key to Off. Remove the key from the switch to prevent accidental starting.

    Setting the Reel Speed

    To achieve a consistent, high quality of cut and a uniform after cut appearance, it is important that you set the reel speed controls (located under the seat) correctly. Adjust the reel speed controls as follows:

    1. Select the height of cut at which the cutting units are set.

    2. Choose the desired ground speed best suited for conditions.

    3. Use the graph on the reel speed chart decal (Figure 32), to determine the proper reel speed setting.

      decal121-7884
    4. To set the reel speed, rotate the knob (Figure 33) until the indicator arrow is in line with the number designating the desired setting.

      g020259

      Note: The reel speed can be increased or decreased to compensate for turf conditions. When using baskets, increase the reel speed to improve collection performance.

    Adjusting the Lift Arm Counterbalance

    You can adjust the counterbalance on the rear cutting unit lift arms 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 one of four settings. Each increment increases or decreases counterbalance on the cutting unit by 1.4 kg (3 lb). The springs can be positioned on the back side of the first spring actuator to remove all counterbalance (forth position).

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

      g020250
    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. Make sure that the fuel tank is at least half full.

    2. Unlatch and raise the 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 6 to 13 mm (1/4 to 1/2 inch) 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 (Figure 35).

      g008891
    4. 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.

    5. Tighten the screw and turn the 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 which 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 the key switch is moved to the On position, the controller diagnostic light will turn ON for 3 seconds and turn OFF to indicate the light is working properly. If the machine kills the light will turn on steady until the key position is changed. The light will blink if the controller detects a malfunction in the electrical system. The light will stop blinking and automatically reset when the key switch is turned to the Off position once the fault has been resolved.

    g020251

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

    • One of the outputs has been shorted.

    • One of the outputs 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:

    • 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 stop when the traction pedal is pressed with operator off of the seat or if the parking brake is left 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, stop the engine, and engage the parking brake.

    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: Make sure correct overlay decal is positioned on 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 will illuminate 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 seat, engage traction pedal, etc.), and note that the appropriate LED on Diagnostic ACE will blink on and off when 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. Replace any defective switches and repair any defective 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, stop the engine, and engage the parking brake.

    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 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 will not operate without the loopback connector installed on the harness. Store the Diagnostic ACE in a dry, secure location in the shop, not on the machine.

    Transporting the Machine

    Use a heavy-duty trailer or truck to transport the machine. Ensure that the trailer or truck has all necessary brakes, lighting, and marking as required by law. Please carefully read all the safety instructions. Knowing this information could help you, your family, pets, or bystanders avoid injury.

    Warning

    Driving on the street or roadway without turn signals, lights, reflective markings, or a slow-moving vehicle emblem is dangerous and can lead to accidents causing personal injury.

    Do not drive the machine on a public street or roadway.

    To transport the machine:

    1. If using a trailer, connect it to the towing vehicle and connect the safety chains.

    2. If applicable, connect the trailer brakes.

    3. Load the machine onto the trailer or truck.

    4. Stop the engine, remove the key, set the brake, and close the fuel valve.

    5. Use the metal tie-down loops on the machine to securely fasten the machine to the trailer or truck with straps, chains, cable, or ropes (Figure 39).

      g027827

    Loading the Machine

    Use extreme caution when loading the machine onto a trailer or a truck. One full-width ramp that is wide enough to extend beyond the front tires of the machine is recommended instead of individual ramps for each tire (Figure 40). If it is not possible to use one full-width ramp, use enough individual ramps to simulate a full-width continuous ramp.

    The ramp should be long enough so that the angles do not exceed 15 degrees (Figure 40). A steeper angle may cause mower components to get caught as the unit moves from the ramp to the trailer or truck. Steeper angles may also cause the machine to tip backward. If loading the machine on or near a slope, position the trailer or truck so that it is on the down side of the slope and the ramp extends up the slope. This will minimize the ramp angle. The trailer or truck should be as level as possible.

    Important: Do not attempt to turn the machine while on the ramp; you may lose control and drive off the side.

    Warning

    Loading a machine onto a trailer or truck increases the possibility of tipping over and could cause serious injury or death.

    • Use extreme caution when operating a machine on a ramp.

    • Use the ROPS (in up position) while using the seat belt when loading the machine. Ensure that the ROPS clears the top of an enclosed trailer.

    • Use only a single, full-width ramp.

    • If individual ramps must be used, use enough ramps to create an unbroken ramp surface wider than the machine.

    • Do not exceed a 15-degree angle between the ramp and the ground or between the ramp and the trailer or truck.

    • Avoid sudden acceleration or deceleration while driving the machine up or down a ramp.

    g000951

    Towing the Machine

    In case of an emergency, you can tow the machine for a short distance; however, Toro does not recommend this as a standard procedure.

    Important: Do not tow the machine faster than 3 to 4 km/h (2 to 3 mph) because the drive system may become damaged. If the machine must be moved a considerable distance, transport it on a truck or trailer.

    1. Locate the bypass valve on the pump (Figure 41) and rotate it 90°.

      g008892
    2. Before starting the engine, close the bypass valve by rotating it 90° (1/4 turn).

      Important: Do not start the engine when the valve is open.
