    • 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 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 area beneath the mowers to be certain they are clear of debris.

    1. Sit on the seat, ensure that the parking brake is engaged, disengage the raise/lower mow control, and move the functional control lever to the NEUTRAL position.

    2. Ensure that your foot is not on the traction pedal and make sure the pedal is in the NEUTRAL position.

    3. Move the choke lever to the ON position (only when starting a cold engine) and the throttle lever to the HALF THROTTLE position.

    4. Start the engine and regulate the choke to keep it running smoothly.

    5. As soon as possible, open the choke by pulling it rearward to the OFF position.

      Note: A warm engine requires little or no choking.

    6. Check the machine out with the following procedures after the engine has started:

      1. Move the throttle lever to the FAST position.

      2. Move the traction-control lever to the MOW position and momentarily engage the reels by moving the raise/lower mow-control lever forward.

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

      3. Move the raise/lower mow control lever rearward until the cutting units raise to the full transport position.

        The cutting units stop rotating as soon as they start to lift. If you release the lever before the cutting units are fully raised, the upward motion stops, but the cutting units still stop rotating.

      4. Lock the parking brake and shut off the engine.

      5. Check the lip of each basket to ensure it is not in contact with the reel during operation.

        If you see signs of contact, adjust the pull arms; refer to Installing the Cutting Units.

      6. Check for oil leaks and tighten the hydraulic fittings if any are found.

        Note: When the machine is new and the bearings and reels are tight, it is necessary to use the FAST throttle lever position for this check. A fast throttle setting may not be required after the break-in period.

        Note: If oil leaks continue to appear, contact your authorized Toro distributor for assistance and, if necessary, replacement parts.

        Important: A trace of oil on the motor or wheel seals is normal. Seals require a small amount of lubrication to perform properly.

    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 engine should not turnover or start, which indicates that the interlock system is operating correctly. Correct the problem if it is not operating properly.

    3. Sit on the seat, move the traction pedal to the NEUTRAL position, move the functional-control lever to the NEUTRAL position, and engage the parking brake.

    4. Start the engine and move the functional-control lever to the MOW position or the TRANSPORT position.

      The engine should shut off, which indicates that the interlock system is operating correctly.

      Correct the problem if it is not operating properly.

    Checking the Operator’s Presence Switch

    1. Sit on the seat, move the traction pedal to the NEUTRAL position, move the functional control lever to the NEUTRAL position, and engage the parking brake.

    2. Start the engine.

    3. Release the parking brake, move the functional control lever to the MOW position, and rise from the seat.

      The engine should shut off, which indicates that the interlock system is operating correctly. Correct the problem if it is not operating properly.

    Checking the Raise/Lower Mow Control

    1. Sit on the seat, move the traction pedal to the NEUTRAL position, move the functional control lever to the NEUTRAL position, and engage the parking brake.

    2. Start the engine.

    3. Move the raise/lower mow control 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.

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

    • 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 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 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: The center cutting unit drops and raises slightly after the front cutting units do; therefore, you should practice gaining the required timing necessary to minimize the cleanup mowing operation.

      Note: The delay in raising and lowering the center cutting unit depends on hydraulic fluid temperature. Cold hydraulic fluid results in a longer delay. As the fluid 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 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 24). 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.

      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 23), which quickly lines the machine up for your next pass.

      g229671

      Note: Try to make as short of a turn as possible, except during warmer weather—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 while the cutting units are engaged, 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 the Job

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

      Note: Use the throttle lever to adjust the machine speed when you cut the periphery. This will match the clip to the green and may 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 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 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 place an undue strain on the baskets and add unnecessary weight to the machine, which increases the load on the machine systems (e.g., engine, hydraulic system, and brakes).

      7. From each side of the bulkhead, tighten the locknuts evenly, securing the traction cable to the bulkhead (Figure 46). Do not twist the cable.

        Note: If cable tension exists when the functional-control lever is in the NEUTRAL position, the machine may creep when you move the lever to the MOW or TRANSPORT position.

    Adjusting the Transport Speed

    Obtaining the Maximum Transport Speed

    The traction pedal comes adjusted for maximum-transport speed, but you may need to adjust it if the pedal reaches full stroke before it contacts the pedal stop, or if you want to a decrease the transport speed.

    To obtain the maximum-transport speed, put the functional control lever in the TRANSPORT position and press down on the traction pedal. If the pedal contacts the stop (Figure 47) before you feel tension on the cable, perform the following adjustment procedure:

    g005520
    1. Put the functional-control lever in the TRANSPORT position and loosen the locknut securing the pedal stop to the floor plate (Figure 47).

    2. Tighten the pedal stop until it does not contact the traction pedal.

    3. Continue applying a light load on the transport pedal and adjust the pedal stop so it contacts the pedal rod and tighten the nuts.

      Important: Ensure that the tension on the cable is not excessive or you will reduce the cable life.

    Reducing the Transport Speed

    1. Press down on the traction pedal and loosen the locknut securing the pedal stop to the floor plate.

    2. Loosen the pedal stop until you obtain the desired transport speed.

    3. Tighten the locknut securing the pedal stop.

    1. While moving forward in transport speed, press the brake pedal; both wheels should apply equally.

      Caution

      Testing the brakes in a confined area where others are present could cause injury.

      Always check the brakes in a wide, open-spaced, flat area free from people and obstructions before and after the adjustment.

    2. If the brakes do not apply equally, adjust the brakes as follows:

      1. Disconnect the brake rods by removing the cotter pin and clevis pin (Figure 49).

        g005135
      2. Loosen the jam nut and adjust the clevis accordingly (Figure 49).

      3. Assemble the clevis to the brake shaft (Figure 49).

      4. When you press the brake pedal, the pedal should move 13 to 26 mm (1/2 to 1 inch) travel before the brake shoes contacts the brake drums. Adjust the clevis on the brake shaft, if necessary, to achieve this setting.

      5. While moving forward in transport speed, press the brake pedal; both brakes should apply equally. Adjust them, if necessary.

    Important: Burnish the brakes annually; refer to the Burnishing the Brakes section.

    Controls System Maintenance

    Adjusting the Cutting Unit Lift/Drop

    The cutting unit lift/drop circuit comes with a flow-control valve (Figure 50). This valve is preset at the factory at approximately 3 turns open, but you may need to adjust it to compensate for differences in hydraulic fluid temperatures, mowing speeds, etc.

    Note: Allow the hydraulic fluid to reach full operating temperature before adjusting the flow-control valve.

    1. Locate the flow-control valve below the seat (Figure 50).

      g229755g033382
    2. Loosen the jam nut at the adjusting knob on the flow control valve.

    3. Adjust the flow control valve as follows:

      • Rotate the knob counterclockwise if the center cutting unit is dropping too late or

      • Rotate the knob clockwise if the center cutting unit is dropping too early.

      Note: You should not need to rotate it more than 1/32 to 1/16 of a turn.

    4. Test the adjustment and repeat step 3 as needed; when finished, tighten the jam nut.

    Adjusting the Lift Cylinders

    To regulate the height of the front cutting units when in the raised (transport) position, you can adjust the front-lift cylinders.

    1. Lower the cutting units to the ground.

    2. Remove the bolts that secure the cover plate of the lift cylinder that you are adjusting from the support brackets of the chassis (Figure 51).

      g229787
    3. Loosen the jam nut securing the clevis fitting to the cylinder of the cutting-unit that needs to be adjusted (Figure 52).

      g229789
    4. Remove the retaining pin and clevis pin (Figure 52)

    5. Rotate the clevis until you attain the desired height (Figure 53).

      g229788
    6. Assemble the clevis fitting to the lift arm with the clevis pin and retaining pin, and tighten the jam nut (Figure 52 and Figure 53).

    7. Install the cover plate and bolts that you removed in step 2.

    Hydraulic System Maintenance

    Hydraulic System Safety

    • Seek immediate medical attention if fluid is injected into skin. Injected fluid must be surgically removed within a few hours by a doctor.

    • 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.

    Servicing the Hydraulic Fluid

    Important: Regardless of the hydraulic fluid type used, any traction unit used for off-green applications, verticutting or used during ambient temperatures above 29°C (85°F) should have the Oil Cooler Kit (Part No. 105-8339) installed.

    Hydraulic Fluid Specifications

    The reservoir is filled at the factory with high-quality hydraulic fluid. Check the level of the hydraulic fluid before you first start the engine and daily thereafter; refer to Checking the Hydraulic-Fluid Level.

    Recommended hydraulic fluid: Toro PX Extended Life Hydraulic Fluid; available in 19 L (5 US gallon) pails or 208 L (55 US gallon) drums.

    Note: A machine using the recommended replacement fluid requires less frequent fluid and filter changes.

    Alternative hydraulic fluids: If Toro PX Extended Life Hydraulic Fluid is not available, you may use another conventional, petroleum-based hydraulic fluid having specifications that fall within the listed range for all the following material properties and that it meets industry standards. Do not use synthetic fluid. Consult with your lubricant distributor to identify a satisfactory product.

    Note: Toro does not assume responsibility for damage caused by improper substitutions, so use products only from reputable manufacturers who will stand behind their recommendation.

     Industry Specifications:Eaton Vickers 694 (I-286-S, M-2950-S/35VQ25 or M-2952-S)

    Note: Many hydraulic fluids are almost colorless, making it difficult to spot leaks. A red dye additive for the hydraulic fluid is available in 20 ml (0.67 fl oz) bottles. A bottle is sufficient for 15 to 22 L (4 to 6 US gallons) of hydraulic fluid. Order Part No. 44-2500 from your authorized Toro distributor.

    Important: Toro Premium Synthetic Biodegradable Hydraulic Fluid 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 oil is available in 19 L (5 US gallons) pails or 208 L (55 US gallons) from your authorized Toro distributor.

    Checking the Hydraulic-Fluid Level

    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 the auxiliary hydraulic tank has a sight window, check the oil level there (Figure 54), and proceed to step 5.

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

      • If the auxiliary hydraulic tank does not have a sight window, locate the dipstick on the top of the machine (Figure 54) and proceed to step 3.

      g221413
    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 it is between the marks on the dipstick, the level is sufficient. If the fluid level is not between the marks, adjust the fluid level accordingly (Figure 55).

      g227716
    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.

      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.

      Note: Do not mix hydraulic fluids.

    6. Install the cap.

      Note: Make a close visual inspection of the hydraulic components. Inspect them for leaks, loose fasteners, missing parts, or improperly routed lines. Make any necessary corrections.

    Changing the Hydraulic Fluid and Filter

    Maintenance Service IntervalMaintenance Procedure
    Every 800 hours
  • If you are not using the recommended hydraulic fluid or have ever filled the reservoir with an alternative fluid, change the hydraulic fluid, filter, and tank breather.
  • Every 1,000 hours
  • If you are using the recommended hydraulic fluid, change the hydraulic-fluid filter.
  • Every 2,000 hours
  • If you are using the recommended hydraulic fluid, change the hydraulic fluid.
  • Hydraulic Fluid Capacity: 25.7 L (6.8 US gallons)

    If the fluid becomes contaminated, have your authorized Toro distributor flush the system. Contaminated fluid looks milky or black when compared to clean fluid.

    1. Clean the area around the filter mounting area (Figure 56). Place a drain pan under the filter and remove the filter.

      g005518

      Note: If you will not be draining the fluid, disconnect and plug the hydraulic line going to the filter.

    2. Fill the replacement filter with the appropriate hydraulic fluid, lubricate the sealing gasket, and hand turn it until the gasket contacts the filter head. Then tighten it 3/4 turn further.

    3. Fill the hydraulic reservoir with hydraulic fluid; refer to Hydraulic Fluid Specifications and Checking the Hydraulic-Fluid Level.

    4. Start the machine and run it at idle for 3 to 5 minutes to circulate the fluid and remove any air trapped in the system. Shut off the engine and check the fluid level.

    5. Dispose of the fluid and filter properly.

    Checking the Hydraulic Lines and Hoses

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Check the hydraulic lines and hoses.
  • 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 59). 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.

    g228674
    g228676
    g228673

    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 breather from the neck of the tank.

    3. Insert a clean rod or screwdriver into the tank neck and gently push down on the switch float (Figure 60); the alarm should sound after the 1-second delay.

      g228675
    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

    Blade Safety

    A worn or damaged blade or bedknife can break, and a piece could be thrown toward you or bystanders, resulting in serious personal injury or death.

    • Inspect the blades and bedknives 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 bedknives; never straighten or weld them.

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

    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. Decide the height of cut at which the cutting units are set.

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

    3. Use table that follows to determine the reel-speed setting for your 5-, 8-, 11-, or 14-blade cutting units (Figure 61).

      g014736
    4. Tilt the operator’s seat forward and support it with the prop rod (Figure 62).

      g229847
    5. To adjust the reel speed by rotating the knob of the reel-speed control (Figure 63) until the indicator arrow are in line with the number that you determined in step 3.

      g229849g229880

      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 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, remove the key, and set the parking brake.

    2. Tilt the operator’s seat forward and support it with the prop rod (Figure 64).

      g229847
    3. Make initial reel to bedknife adjustments appropriate for honing all the cutting units that you are backlapping; refer to the Cutting Unit Operator's Manual.

    4. Rotate the backlap lever to the R position (Figure 65).

      g229849g229848
    5. Rotate the reel-speed knob to setting 1 (Figure 65).

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

      Important: Do not change the engine speed while backlapping or the reels may stall. Only backlap at idle engine speed.

    7. With the mow/transport lever in the NEUTRAL position, move the raise/lower mow control forward to start the backlapping operation on the reel.

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

      • 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.

      • 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.

    9. Repeat the steps 4 through 8 for all cutting units that you want to backlap.

    10. When finished, return the backlap lever to the F position, move the reel speed knob to the desired reel-speed setting, lower the seat, and wash all lapping compound off of the cutting units. Adjust cutting unit reel to bedknife as needed.

      Important: If you do not return the backlap lever to the F position after backlapping, the cutting units will not raise or function properly.
