Adjusting the Clip-Control Feature

Understanding the Radius-Dependent-Speed (RDS) System

To achieve a consistent, high quality-of-cut and a uniform after cut appearance, the machine is equipped with the patent-pending Radius Dependent Speed™ (RDS) system. The RDS system is a clip-control and independent wheel-speed feature that varies the speeds of each reel motor and each traction motor to maintain a constant clip and reduce turf scrubbing in turns while cutting.

When the machine is turning while cutting (e.g., during the clean-up pass), the reel on the inside of the turn will rotate at a slower rpm than the reel on the outside of the turn. The center reel splits the difference of the inside and outside reel speeds so that all three cutting units have the same clip. The sharper the turn, the greater the difference in reel speeds. Additionally, if the machine speed changes while you are cutting, the RDS system adjusts the reel speed to maintain a constant clip. This feature reduces turf thinning on the inside reel (in comparison to other riding greens mowers), which virtually eliminates triplex ring.

The RDS system also adjusts each wheel-motor speed during a turn, similar to the reel-motor speeds changing in a turn. The inside wheel motor will turn at a slower rpm than the outside wheel motor. This minimizes wheel scrubbing in the turn and can reduce triplex ring.

Setting the Clip-Control Feature

Navigate to the CLIP CONTROL option to set the RDS system feature.

  • Clip control set to ON: The machine uses your settings from the HEIGHT OF CUT (HOC) and BLADE COUNT options and the left and right wheel speeds to determine the speed of each reel.

  • Clip control set to OFF: The machine uses your setting from the REEL SPEED option.

Note: The factory default setting is ON.

Adjusting the Height of Cut (HOC)

Navigate to the HEIGHT OF CUT (HOC) option to adjust the height of cut. The clip control feature must be set to ON to use this feature; refer to Setting the Clip-Control Feature.

Performing Daily Maintenance

Maintenance Service IntervalMaintenance Procedure
Before each use or daily
  • Inspect the seat belt(s) for wear, cuts, and other damage. Replace the seat belt(s) if any component does not operate properly.
  • Before starting the machine each day, perform the following procedures:

    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; and substantial, slip-resistant footwear. Tie back long hair and do not wear loose clothing or loose jewelry.

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

    • Use your full attention while operating the machine. Do not engage in any activity that causes distractions; otherwise, injury or property damage may occur.

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

    • Do not carry passengers on the machine.

    • Keep bystanders and children out of the operating area. If co-workers must be present, use caution and ensure that the grass baskets are installed on the machine.

    • 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.

    • Keep your hands and feet away from the cutting units.

    • 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.

    • Stop the cutting units whenever you are not mowing.

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

    • Operate the engine only in well-ventilated areas. Exhaust gases contain carbon monoxide, which is lethal if inhaled.

    • Do not leave a running machine unattended.

    • Before you leave the operating position, do the following:

      • Park the machine on a level surface.

      • Lower the cutting units to the ground and ensure that they are disengaged.

      • Engage the parking brake.

      • Shut off the engine and remove the key.

      • Wait for all movement to stop.

    • Operate the machine only in good visibility and appropriate weather conditions. Do not operate the machine when there is the risk of lightning.

    Rollover Protection System (ROPS) Safety

    • Do not remove any of the ROPS components 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.

    • 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 all damaged ROPS components. Do not repair or alter them.

    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 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 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 Owner’s 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. If you are starting a cold engine, move the choke lever to the CLOSED position.

    2. Insert and rotate the key to the ON position.

    3. Wait until the splash screen appears on the InfoCenter, then move the key to the START position until the engine starts.

    4. Once the engine starts, remove your hand from the key; the key will automatically move to the ON position.

    5. Adjust the choke to run the engine smoothly. As soon as possible, open the choke by pulling it rearward to the OPEN position.

      Note: A warm engine requires little or no choking.

      Note: A fault occurs if the engine cranks longer than 30 seconds.

    Checking the Machine after Starting the Engine

    1. Sit in the operator’s seat and fasten the seatbelt.

    2. Move the function-control switch to the MOW position.

    3. Disengage the parking brake.

    4. Move the lift/lower joystick forward momentarily.

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

    5. Move the lift/lower joystick rearward.

      The cutting reels should stop rotating and the cutting units should raise to the full transport position.

    Shutting Off the Engine

    1. Transport the machine to a level surface.

    2. Move the function-control switch to the NEUTRAL position.

    3. Engage the parking brake.

    4. Rotate the key to the OFF position to shut off the engine.

    5. Remove the key.

    Understanding the Safety-Interlock System

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Check the safety-interlock system.
  • Caution

    If the 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.

    The purpose of the safety-interlock system is to prevent operation of the machine where there is possible injury to you or damage to the machine.

    The safety-interlock system prevents the machine from moving unless:

    • The parking brake is disengaged.

    • You are seated in the operator's seat.

    • The function-control switch is in the MOW position or the TRANSPORT position.

    Additionally, the safety-interlock system prevents the reels from operating unless the function-control switch is in the MOW position (except when the machine is in Backlap Mode).

    Checking the Safety-Interlock System

    Perform the following steps to check the interlock system:

    • Rise from the seat, start the engine, disengage the parking brake, move the function-control switch to the MOW or TRANSPORT position, and engage the traction pedal.

      The machine should not move, as you are not in the seat. This indicates that the interlock system is operating correctly. Correct the problem if it is not operating properly.

    • Sit in the seat, start the engine, engage the parking brake, move the function-control switch to the MOW or TRANSPORT position, and engage the traction pedal.

      The machine should not move, as the parking brake is engaged. This indicates that the interlock system is operating correctly. Correct the problem if it is not operating properly.

    • Sit in the seat, start the engine, disengage the parking brake, move the function-control switch to the NEUTRAL position, and engage the traction pedal.

      The machine should not move, as the function-control switch is in the NEUTRAL position. This indicates that the interlock system is operating correctly. Correct the problem if it is not operating properly.

    • Sit on the seat, move the traction pedal to the NEUTRAL position, move the function-control switch to the NEUTRAL position, engage the parking brake, start the engine, and move the lift/lower joystick forward to lower the cutting units.

      The cutting units should lower but not start rotating. If they start rotating, the interlock system is not operating correctly; correct the problem before operating the machine.

    Driving the Machine without Mowing

    • Ensure that the cutting units are fully raised.

    • Sit in the seat, disengage the parking brake, and move the function-control switch to the TRANSPORT position to drive the machine without mowing.

    • 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

    Before mowing greens, find a clear area and practice performing basic machine functions (e.g., starting and stopping the machine, raising and lowering the cutting units, and turning).

    Inspect the green for debris, remove anything that may damage the cutting units while mowing, 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 will have a greater chance of being cut.

    Cutting the Green

    1. 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.

    2. Move the function-control switch to the MOW position.

    3. Push forward the lift/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: The center cutting unit lifts or lowers slightly after the front cutting units do; therefore, you should practice gaining the required timing necessary to minimize the cleanup mowing operation and prevent scalping of the fringe.The center cutting unit lift and lower is based on ground speed. A slower ground speed increases the lift or lower delay; a faster speed decreases the lift or lower delay. The machine monitors the ground speed and updates this delay so that all three cutting units drop in a line.

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

      Note: To assist in maintaining a straight line across the green and keeping the machine an equal distance from the edge of the previous cut, imagine a 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 31). 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 lift/lower joystick rearward and hold it until all the cutting units have risen. This stops the reels and lifts the cutting units.

      Important: 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 to ease the lineup for the next pass, momentarily turn the machine in the opposite direction, then turn it in the direction of the uncut portion. This movement is a tear-shaped turn (Figure 30), which quickly lines the machine up for your next pass.

      Note: If the slow in turn function is engaged, the machine slows down during the turn without requiring you to release pressure on the traction pedal.

      g229671

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

      g005116

      Important: Never stop the machine on a green, especially while the cutting units are engaged; damage to the turf may result. Stopping the machine on a green may leave marks or indentations from the wheels.

    Cutting the Periphery and Finishing the Job

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

      Refer to Understanding the Radius-Dependent-Speed (RDS) System to improve the after-cut appearance and reduce triplex ring.

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

    2. When you finish mowing the outer periphery, tap the lift/lower joystick rearward to stop the reels (if the tap-off delay feature is engaged), then drive off the green. When all the cutting units are off the green, move the lift/lower joystick rearward to raise the cutting units.

      Note: This step minimizes grass clumps left on the green.

    3. Replace the flag.

    4. Empty the grass baskets of all clippings before you transport the machine to the next green.

      Note: Heavy wet clippings cause strain on the baskets, suspensions, and actuators. This adds unnecessary weight to the machine, which decreases energy efficiency.

    After Operation

    After Operation Safety

    General Safety

    • Engage the parking brake, 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 and drives to help prevent fires. Clean up oil or fuel spills.

    • Shut off the fuel while storing or hauling the machine.

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

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

    • 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.

    Towing Safety

    • Tow only with a machine that has a hitch designed for towing. Do not attach towed equipment except at the hitch point.

    • Follow the manufacturer’s recommendation for weight limits for towed equipment and towing on slopes. On slopes, the weight of the towed equipment may cause loss of traction and loss of control.

    • Never allow children or others in or on towed equipment.

    • Travel slowly and allow extra distance to stop when towing.

    Inspecting and Cleaning after Mowing

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Inspect and cleanup after mowing.
  • After mowing, thoroughly wash the machine with a garden hose without a nozzle so that excessive water pressure does not contaminate and damage the seals, bearings, and electronics. Do not wash a warm engine or the electrical connections with water.

    Important: Do not use brackish or reclaimed water to clean the machine.

    Important: Do not use power-washing equipment to wash the machine. Power-washing equipment may damage the electrical system, loosen important decals, or wash away necessary grease at friction points. It may force water under seals, contaminating oil or grease contained housings. Avoid excessive use of water near the control panel, engine, and battery.

    Important: Do not wash the machine with the engine running. Washing the machine with the engine running may result in internal engine damage.

    Important: Do not force water into the muffler. Water inside the muffler may result in internal engine damage or reduced engine performance.

    Inspect the cutting units for sharpness after you clean the machine.

    Hauling the Machine

    • Use care when loading or unloading the machine into a trailer or a truck.

    • Use a full-width ramp for loading the machine into a trailer or a truck.

    • Tie the machine down securely using straps, chains, cable, or ropes. Both front and rear straps should be directed down and outward from the machine (Figure 32).

      g274815
    • After the machine is secured for transport, close the fuel-shutoff valve.

    Towing the Machine

    Note: Refer to Figure 33 for this procedure.

    g267401

    To tow the machine, you must perform the following procedure to release the brake actuator:

    1. Engage the parking brake.

    2. Remove the key and disconnect the main-power connectors.

      Important: If the main-power connectors are connected while towing, electrical damage may result.

    3. Close the fuel-shutoff valve.

    4. Chock both sides of the front tires.

    5. Release tension on the spring by loosening the nut that secures the eyebolt to the spring bracket.

    6. Remove the spring.

    7. Insert a ratchet (3/8 inch) through the hole of the arm bracket and push in the actuator shaft.

      Danger

      When the actuator is released from the brake, the machine is able to free wheel. A free-wheeling machine can cause serious injury to bystanders.

      If the machine is not being towed, engage the parking brake.

    8. Engage the parking brake.

    9. Remove the chocks from the tires.

    10. If the 3-Wheel Drive Kit is installed, disconnect the kit-wire-harness connectors from the main wire harness.

      Important: If the kit and machine wire harnesses are connected while towing, electrical damage may result.

    11. When the machine is ready to be towed, disengage the parking brake.

    12. Have an assistant sit in the seat, fasten the seatbelt, and use the brake while you tow the machine.

      Note: This ensures that the machine is under control when you tow the machine over undulations and slopes.

    13. Use the rear castor fork to tow the machine (Figure 34).

      Important: Do not exceed 5 km/h (3 mph) while towing the machine. Damage to the electrical components may result.

      g270135

    After you have towed the machine to your intended destination, perform the following steps:

    1. Engage the parking brake.

    2. Remove the tow strap from the castor fork.

    3. Prepare for operation by tightening the eyebolt nut so that the spring length is 11.4 cm (4.5 inches) when installed (Figure 33).

    Driving the Machine Without Engine Power
