During Operation

During Operation Safety

General Safety

  • The owner/operator can prevent and is responsible for accidents that may cause personal injury or property damage.

  • Wear appropriate clothing, including eye protection; long pants; slip-resistant, substantial foot protection; and hearing protection. Tie back long hair and do not wear jewelry.

  • Do not operate the machine while ill, tired, or under the influence of alcohol or drugs.

  • Never carry passengers on the machine and keep bystanders and pets away from the machine during operation.

  • Operate the machine only in good visibility to avoid holes or hidden hazards.

  • Avoid mowing on wet grass. Reduced traction could cause the machine to slide.

  • Before you start the engine, ensure that all drives are in neutral, the parking brake is engaged, and you are in the operating position.

  • Keep your hands and feet away from the cutting units. Keep clear of the discharge opening at all times.

  • Look behind and down before backing up to be sure of a clear path.

  • Use care when approaching blind corners, shrubs, trees, or other objects that may obscure your vision.

  • Do not mow near drop-offs, ditches, or embankments. The machine could suddenly roll over if a wheel goes over the edge or if the edge gives way.

  • Stop the cutting units whenever you are not mowing.

  • Stop the machine and inspect the cutting units after striking an object or if there is an abnormal vibration in the machine. Make all necessary repairs before resuming operation.

  • Slow down and use caution when making turns and crossing roads and sidewalks with the machine. Always yield the right-of-way.

  • Disengage the drive to the cutting unit and shut off the engine before adjusting the height of cut (unless you can adjust it from the operating position).

  • Never run an engine in an area where exhaust gasses are enclosed.

  • Never leave a running machine unattended.

  • Before leaving the operating position (including to empty the catchers or to unclog the chute), do the following:

    • Park the machine on level ground.

    • Disengage the power take-off and lower the attachments.

    • Engage the parking brake.

    • Shut off the engine and remove the key.

    • Wait for all moving parts to stop.

  • Do not operate the machine when there is the risk of lightning.

  • Do not use the machine as a towing vehicle.

  • Use accessories, attachments, and replacement parts approved by The Toro® Company only.

Rollover Protection System (ROPS) Safety

  • Do not remove the ROPS from the machine.

  • Ensure that the seat belt is attached and that you can release it quickly in an emergency.

  • Always wear your seat belt if your machine has a fixed roll bar.

  • Check carefully for overhead obstructions and do not contact them.

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

  • Replace a damaged ROPS. Do not repair or alter it.

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. Before you operate the machine, review the site conditions to determine whether the machine can be operated 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 units lowered to the ground while operating on slopes. Raising the cutting units 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.

Breaking in the Machine

Refer to the engine manual supplied with the machine for oil change and maintenance procedures recommended during the break-in period.

Only 8 hours of operation is required for the break-in period.

Since the first hours of operation are critical to future dependability of the machine, monitor its functions and performance closely so that minor difficulties, which could lead to major problems, are noted and can be corrected. Inspect the machine frequently during break-in for signs of oil leakage, loose fasteners, or any other malfunction.

Starting the Engine

Note: Inspect the areas beneath the cutting units to ensure that they are clear of debris.

  1. Sit on the seat, engage the parking brake, disengage the raise/lower mow control and move the functional-control lever to the NEUTRAL position.

  2. Ensure that the traction pedal is in the NEUTRAL position and that you foot is off the pedal.

  3. If you are starting a cold engine, move the choke to the ON position.

  4. Move the throttle lever to the HALF THROTTLE position.

  5. Insert and rotate the ignition key clockwise until the engine starts.

  6. After the engine starts, adjust the choke to run the engine smoothly. As soon as possible, open the choke by pulling it rearward to the OFF position. A warm engine requires little or no choking.

Checking the Machine after Starting the Engine

  1. Move the throttle lever to the FAST position.

  2. Move the raise/lower mow control lever forward momentarily.

    The cutting units should lower and all the reels should rotate.

    • Use the brakes to slow the machine while going down steep hills to avoid loss of control.

    • Always approach rough areas at a reduced speed and cross severe undulations carefully.

    • Familiarize yourself with the width of the machine. Do not attempt to pass between objects that are close together to prevent costly damage and downtime.

    Mowing the Green

    Important: If the leak detector alarm (if equipped on your model) sounds or you notice an oil leak while cutting on a green, immediately raise the cutting units, drive directly off the green, and stop the machine in an area away from the green. Determine the cause of the leak and correct the problem.

    Before mowing greens, find a clear area and practice starting and stopping the machine, raising and lowering the cutting units, turning, etc.

    Inspect the green for debris, remove the flag from the cup, and determine the best direction to mow. Base the direction to mow on the previous mowing direction. Always mow in an alternate pattern from the previous mowing so that the grass blades are less apt to lay down and therefore be difficult to trap between the reel blades and the bedknife.

    Cutting the Green

    1. Approach the green with the functional-control lever in the MOW position and the throttle at full speed.

    2. Start on 1 edge of the green so that you can use the ribbon procedure of cutting.

      Note: This holds compaction to a minimum and leaves a neat, attractive pattern on the greens.

    3. Push forward the raise/lower mow lever as the front edges of the grass baskets cross the outer edge of the green.

      Note: This procedure drops the cutting units to the turf and starts the reels.

      Important: There is a delay raising and lowering the center cutting unit; therefore, you should practice—gaining the required timing necessary to minimize the cleanup mowing operation.

      Note: The delay raising and lowering the center cutting unit depends on hydraulic fluid temperature. Cold hydraulic fluid results in a longer delay. As the temperature increases the delay time becomes shorter.

    4. Overlap a minimal amount with the previous cut on return passes.

      Note: To assist in maintaining a straight line across the green and keep the machine an equal distance from the edge of the previous cut, establish an imaginary sight line approximately 1.8 to 3 m (6 to 10 ft) ahead of the machine to the edge of the uncut portion of the green (Figure 24). Some find it useful to include the outer edge of the steering wheel as part of the sight line; i.e., keep the steering wheel edge aligned with a point that is always kept the same distance away from the front of the machine.

    5. As the front edges of the baskets cross the edge of the green, pull back the raise/lower mow lever rearward and hold it until all the cutting units have risen. This stops the reels and lifts the cutting units.

      Note: It is important to time this step correctly so that you do not cut into the fringe area yet cut as much of the green as possible to minimize the amount of grass left to mow around the outer periphery.

    6. To cut down on operating time and ease lineup for the next pass, momentarily turn the machine in the opposite direction, then turn it in the direction of the uncut portion; a tear-shaped turn (Figure 23) to quickly line up for your next pass.

      g229671

      Note: Try to make as short of a turn as possible except during warmer weather when a wider arc minimizes the turf bruising.

      g005116

      Note: The steering wheel does not return to its original position after you complete a turn.

      Important: Never stop the machine on a green with the cutting unit reels operating as damage to the turf may result. Stopping the machine on a wet green may leave marks or indentations from the wheels.

    Cutting the Periphery and Finishing Job

    1. Finish cutting the green by mowing the outer periphery. Change the direction of cutting from the previous mowing.

      Note: Always keep weather and turf conditions in mind and be sure to change the direction of mowing from the previous cutting.

    2. When finished mowing the outer periphery, tap the raise/lower mow lever rearward to stop the reels, then drive off the green. When all the cutting units are off the green, raise the cutting units.

      Note: This minimizes grass clumps left on the green.

    3. Replace the flag.

    4. Empty the grass baskets of all clippings before transporting to the next green.

      Note: Heavy wet clippings place an undue strain on the baskets and add unnecessary weight to the machine, thereby increasing the load on the engine, hydraulic system, brakes, etc.

    After Operation

    Important: The ISO VG 46 Multigrade fluid has been found to offer optimal performance in a wide range of temperature conditions. For operation in consistently high ambient temperatures, 18°C (65°F) to 49°C (120°F), ISO VG 68 hydraulic fluid may offer improved performance.

    Premium Biodegradable Hydraulic Fluid-Mobil EAL EnviroSyn 46H

    Important: Mobil EAL EnviroSyn 46H is the only synthetic biodegradable fluid approved by Toro. This fluid is compatible with the elastomers used in Toro hydraulic systems and is suitable for a wide-range of temperature conditions. This fluid is compatible with conventional mineral oils, but for maximum biodegradability and performance the hydraulic system should be thoroughly flushed of conventional fluid. The fluid is available in 19 L (5 gallon) containers or 55 gallon drums from your Mobil Distributor.

    Important: Many hydraulic fluids are almost colorless, making it difficult to spot leaks. A red dye additive for the hydraulic system fluid is available in 20 ml (2/3 oz) bottles. One bottle is sufficient for 15 to 22 L (4 to 6 gallons) of hydraulic fluid. Order Part No. 44-2500 from your authorized Toro distributor. This red dye is not recommended for use with biodegradable fluids. Use food coloring.

    Checking the Hydraulic-Fluid Level

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Check the hydraulic-fluid level.
  • The hydraulic-fluid reservoir is filled at the factory with high quality hydraulic fluid. Before operating the machine each day, check the level of the hydraulic fluid. Your machine has a dipstick or a white plastic window on the front of the hydraulic-fluid reservoir (behind the seat on the left side) that is used to check the hydraulic-fluid level. The fluid should be between the window lines or the dipstick marks; if not, add the appropriate fluid.

    Important: To prevent system contamination, clean the top of the hydraulic fluid containers before puncturing them. Ensure that the pour spout and funnel are clean.

    1. Position the machine on a level surface.

      Note: Ensure that the machine has cooled down so the fluid is cold.

    2. Check the fluid level according to the tank on your machine:

      • If your machine has a fuel gauge at the top of the fuel tank, locate the dipstick for the hydraulic system at the top of the leak detector tank (Figure 36) and proceed to step 3.

        g228585
      • If your machine has a fuel sight gauge at the side of the fuel tank, locate the dipstick for the hydraulic system at the top of the hydraulic tank (Figure 37) and proceed to step 5.

        Note: If the fluid level is between the 2 marks on the sight window, the fluid level is sufficient.

        g228586
    3. Remove the dipstick and wipe it with a clean rag, then screw the dipstick back into the tank.

    4. Remove the dipstick and check the fluid level. If the fluid is between the marks on the dipstick, the level is sufficient. If the fluid level is not between the marks, more fluid is needed.

    5. Remove the cap from the hydraulic fluid tank and slowly fill the tank with the appropriate high-quality hydraulic fluid until the level is between the 2 marks on the sight window or dipstick.

      Note: Do not mix different types of hydraulic fluid.

    6. Install the cap.

      Note: Perform a close visual inspection of the hydraulic components. Inspect them for issues (e.g., leaks, loose fasteners, missing parts, and improperly routed lines). Make any necessary corrections.

    Hydraulic fluid escaping under pressure can penetrate skin and cause injury.

    • Ensure that all hydraulic fluid hoses and lines are in good condition and all hydraulic connections and fittings are tight before applying pressure to the hydraulic system.

    • Keep your body and hands away from pinhole leaks or nozzles that eject high-pressure hydraulic fluid.

    • Use cardboard or paper to find hydraulic leaks.

    • Safely relieve all pressure in the hydraulic system before performing any work on the hydraulic system.

    • Get immediate medical help if fluid is injected into skin.

    Check 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.

    Checking the Leak Detector

    The leak detector system is designed to assist in early detection of hydraulic-fluid-system leaks. If the fluid level in the main hydraulic reservoir is lowered by 118 to 177 ml (4 to 6 oz), the float switch in the tank will close. After a 1 second delay, the alarm sounds, alerting the operator (Figure 41). Expansion of fluid, due to normal heating during machine operation, causes the fluid to transfer into the auxiliary fluid reservoir. The fluid returns to the main tank when you turn off the ignition switch.

    g229109
    g229110

    Checking the System Operation

    1. With ignition switch in the ON position, move the leak detector switch rearward and hold. After the 1-second delay elapses, the alarm should sound.

    2. Release the leak-detector switch.

    Checking the Leak-Detector-System Operation

    1. Move the ignition switch to the ON position. Do not start the engine.

    2. Remove the hydraulic-tank cap from the neck of the tank.

    3. Insert a clean rod or screwdriver into the tank neck and gently push down on the float switch (Figure 42); the alarm should sound after the 1-second delay.

      g229112
    4. Release the float; the alarm should stop sounding.

    5. Install the hydraulic-tank cap.

    6. Move the ignition switch to the OFF position.

    Operating the Leak Detector

    The leak detector alarm may sound for 1 of the following reasons:

    • A leak of 118 to 177 ml (4 to 6 oz) has occurred.

    • The fluid level in the main reservoir is reduced by 118 to 177 ml (4 to 6 oz) due to contraction of the fluid by cooling.

    If the alarm sounds, turn off the machine as quickly as possible and inspect it for leaks. If the alarm sounds while operating on a green, drive off the green first. Determine the source of the leak and repair it before continuing operation.

    If you do not find a leak and suspect a false alarm, move the ignition switch to the OFF position and allow the machine to stand for 1 to 2 minutes to allow the fluid levels to stabilize. Then start the machine and operate it in a non-sensitive area to confirm that no leak exists.

    False alarms, due to fluid contraction, may be caused by extended idling of the machine after normal operation. A false alarm may also occur if you work the machine at a reduced workload after an extended period of a heavier workload. To avoid false alarms, turn the machine off rather than idling for extended periods.

    Cutting Unit Maintenance

    Cutting Unit Safety

    A worn or damaged blade or bed-knife can break, and a piece could be thrown at you or bystanders, resulting in serious personal injury or death.

    • Inspect the blades and bed-knives periodically for excessive wear or damage.

    • Use care when checking the blades. Wear gloves and use caution when servicing them. Only replace or backlap the blades and bed-knives; never straighten or weld them.

    • On machines with multiple cutting units, take care when rotating a reel; it can cause the reels in the other cutting units to rotate.

    Installing and Removing the Cutting Units

    Caution

    The cutting-unit blades are sharp and can cut your hands.

    Wear heavy leather or cut-resistant gloves when handling the cutting units.

    Note: When sharpening, setting the height-of-cut, or performing other maintenance procedures on the cutting units, store the cutting unit reel motors in the storage location on the front of the suspension arms to prevent damage to them.

    Important: Do not raise the suspension to the transport position when the reel motors are in the holders in the machine frame. Damage to the motors or hoses could result.

    Important: Whenever you need to tip the cutting unit, prop up the rear of the cutting unit to ensure that the nuts on the bedbar adjusting screws are not resting on the work surface (Figure 43).

    g014596

    Installing the Cutting Units

    1. Lift up on the footrest and swing it open, allowing access to the center cutting unit position (Figure 44).

      Caution

      The footrest can pinch fingers if it falls into the closed position.

      Keep your fingers clear of the area where the footrest seats while it is open.

      g014602
    2. Position the cutting unit under the center suspension arm.

    3. With the latches on the suspension-arm bar pointing up (i.e., open) (Figure 45), push the suspension arm down so that the bar fits over the bar across the top of the cutting unit (Figure 46).

      g014609
      g014611
    4. Close the latches down and around the cutting-unit bar and lock them in place (Figure 45).

      Note: You can hear a click and feel when the latches are properly locked in place.

    5. Coat the spline shaft of the cutting unit motor with clean grease (Figure 47).

    6. Insert the motor into the left side of the cutting unit (as viewed from the operator's position) and pull the motor retaining bar on the cutting unit toward the motor until you hear a click from both sides of the motor (Figure 47).

      g014690
    7. Mount a grass basket onto the basket hooks on the suspension arm.

    8. Repeat this procedure for the other cutting units.

    Removing the Cutting Units

    1. Park the machine on a clean level surface, lower the cutting units to the ground until the suspension hydraulics are fully extended, shut off the engine, and set the parking brake.

    2. Push the motor retaining bar out of the slots on the motor toward the cutting unit and remove the motor from the cutting unit.

      g014605
    3. Move the motor to the storage location on the front of the suspension arm (Figure 49).

      g014608

      Note: When sharpening, setting the height-of-cut, or performing other maintenance procedures on the cutting units, store the cutting unit reel motors in the storage location on the front of the suspension arms to prevent damage to them.

      Important: Do not raise the suspension to the transport position when the reel motors are in the holders in the machine frame. Damage to the motors or hoses could result. If you must move the traction unit without the cutting units installed, secure them to the suspension arms using cable ties.

    4. Open the latches on the suspension-arm bar of the cutting unit you are removing (Figure 45).

    5. Disconnect the latches from the cutting-unit bar.

    6. Roll the cutting unit out from under the suspension arm.

    7. Repeat steps 2 through 6 for the other cutting units as required.

    Checking the Reel-to-Bedknife Contact

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Check the reel-to-bedknife contact.
  • Each day before operating the machine, check the reel-to-bedknife contact, regardless if the quality of cut had previously been acceptable. There must be light contact across the full length of the reel and bedknife; refer to the Cutting Unit Operator’s Manual.

    Setting the Reel Speed

    To achieve a consistent, high-quality cut and a uniform, after-cut appearance, you must correctly set the reel speed control (located on the manifold block under the cover to the left of the seat). Adjust the reel speed control 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 table that follows to determine the reel-speed setting for your 5-, 8-, 11-, or 14-blade cutting units. (Figure 50)

      g014736
    4. Adjust the reel speed by rotating the knob (Figure 51) until the indicator arrows are in line with the number you determined in step 3.

      g014623

      Note: You can increase or decrease the reel speed to compensate for turf conditions.

    Backlapping the Reels

    Warning

    Contact with the reels or other moving parts can result in personal injury.

    • Keep your fingers, hands, and clothing away from the reels or other moving parts.

    • Never attempt to turn the reels by hand or foot while the engine is running.

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

    2. Remove the plastic cover to the left side of the seat.

    3. Make 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.

      Danger

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

      • Never change the engine speed while backlapping.

      • Backlap only at idle engine speed.

    4. Start the engine and run at low idle speed.

    5. Rotate the backlap lever to the REVERSE (R) position (Figure 52).

      g014620
    6. Rotate the reel-speed control to setting 1 (Figure 53).

      g014623
    7. With the functional-control lever in the NEUTRAL position, move the raise/lower mow control forward to start the backlapping operation on the designated reels.

    8. Apply lapping compound with a long handle brush. Never use a short handled brush.

    9. If the reels stall or become erratic while backlapping, select a higher reel speed setting until the speed stabilizes, then return the reel speed to setting 1 or to your desired speed.

    10. To make an adjustment to the cutting units while backlapping, turn the reels off by moving the raise/lower mow control rearward and shut off the engine. After completing adjustments, repeat steps 4 through 8.

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

    12. When finished, return the backlap levers to the FORWARD (F) position, replace the cover, and wash all lapping compound off of the cutting units. Adjust cutting unit reel to bedknife as needed. Move the cutting unit reel speed control to the desired mowing position.

      Important: If the backlap lever is not returned to the FORWARD (F) position after backlapping, the cutting units will not raise or function properly.

    Diagnostics System

    Diagnosing the Service Indicator Light

    The service indicator light illuminates in the event of a fault in the machine. When this light is on, you can access the computer codes to diagnose the problem by entering diagnostic mode. In diagnostic mode, the service indicator light flashes a number of times, giving you the error code that you or your authorized Toro distributor can use to identify the problem.

    Note: You cannot start the engine in diagnostic mode.

    Entering Diagnostic Mode

    1. Stop the machine, set the parking brake, and turn the ignition key to the OFF position.

    2. Move the functional-control lever to the TRANSPORT position.

    3. Ensure that the backlap lever is set to the FORWARD (F) position.

    4. Get off the seat.

    5. Hold the raise/lower mow control in the RAISED position.

    6. Turn the ignition switch to the RUN position.

    7. Count the codes as they begin to flash (you may release the raise/lower mow control once they begin flashing).

    When finished, turn the key to the OFF position to exit diagnostic mode.

    Determining the Error Code

    The system will display the last 3 faults that occurred in the last 40 hours. It displays the faults through a series of blinking lights, as follows:

    • If there are no faults, the light will blink steadily at a medium rate without pauses (1 Hz).

    • If there is a fault, it will first blink the tens place, followed by a pause, followed by the ones place. For the following examples, a # represents a blink. Examples:

      • If the code is 15, the blink pattern will be #_#####

      • If the code is 42, the blink pattern will be ####_##

      • If the code is 123, the blink pattern will be ############_###

    • If there are more than 1 fault, the tens place of the next fault will begin after a pause after the ones place of the first fault.

      Note: The system stores only the 3 most recent fault codes.

    For a list of error codes, refer to your authorized Toro distributor or the Service Manual.

    Storage

    If you wish to store the machine for a long period of time, the perform following steps:

    1. Remove accumulations of dirt and old grass clippings. Sharpen the reels and bedknives, if necessary; refer to the cutting unit Operator's Manual. Coat the bedknives and reel blades with a rust preventive. Oil all lubrication points.

    2. Raise and support the machine to remove its weight from the tires.

    3. Replace the hydraulic fluid and filter and inspect the hydraulic lines and fittings. Replace, if necessary; refer to Changing the Hydraulic Fluid and Filter and Checking the Hydraulic Lines and Hoses.

    4. All fuel should be removed from the fuel tank. Run the engine until it stops. Replace the fuel filter; refer to Replacing the Fuel Filter.

    5. While the engine is still warm, drain the oil from the crankcase. Refill it with fresh oil; refer to Changing the Engine Oil and Filter.

    6. Remove the spark plugs, pour one ounce of SAE 30 oil into the cylinders, and crank slowly to distribute the oil. Replace the spark plugs; refer to Replacing the Spark Plugs.

    7. Clean dirt and chaff from the cylinder, cylinder head fins, and blower housing.

    8. Remove the battery and charge it fully. Either store it on the 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.

    9. If possible, store the machine in a warm, dry location.
