  • If you spill fuel, do not attempt to start the engine; avoid creating any source of ignition until the fuel vapors have dissipated.

Fuel Specification

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.

Use summer grade diesel fuel (No. 2-D) at temperatures above -7°C (20°F) and winter grade (No. 1-D or No. 1-D/2-D blend) below that temperature. Use of winter grade fuel at lower temperatures provides lower flash point and cold flow characteristics which eases starting and reduces fuel filter plugging.

Use of summer grade fuel above -7°C (20°F) contributes toward longer fuel pump life and increased power compared to winter grade fuel.

Important: Do not use kerosene or gasoline instead of diesel fuel. Failure to observe this caution damages the engine.

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 blended.

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

Fuel Tank Capacity

53 L (14 US gallons)

Adding Fuel

    2. Turn the key to the OFF position and remove it from the switch.

    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 to the proper setting. Adjust the reel speed as follows:

    1. In the InfoCenter, under the settings menu, enter the blade count, mow speed and HOC to calculate the proper reel speed.

    2. If further adjustments are required, in the settings menu, scroll down to the F Reel RPM, R Reel RPM or both.

    3. Press the right button to change the reel speed value. As the speed setting is changed, the display will continue to show the calculated reel speed based on blade count, mow speed and HOC, but the new value will also be displayed.

      Note: You may need to increase or decrease the reel speed to compensate for varying turf conditions.

    Adjusting the Lift-Arm Counterbalance

    Rear Cutting Units

    Caution

    The springs are under tension and could cause personal injury.

    Use caution when adjusting the springs.

    You can adjust the amount of counterbalance force applied to the rear cutting-units to help compensate for different turf conditions, and to maintain a uniform height of cut in rough conditions or in areas of thatch buildup.

    You adjust counterbalance force of each torsion spring to 1 of 4 settings. Each increment increases or decreases the counterbalance force on the cutting unit by 2.3 kg (5 lb). You can position the springs at the back side of the first spring actuator to remove all counterbalance (fourth position).

    Note: To remove all counterbalance force, position the long leg of the torsion spring above the shouldered stud.

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

    2. Insert the long end of the counterbalance spring into a tube or similar object, and pivot the spring around the shouldered stud to the desired position (Figure 50).

      g375585
    3. Repeat steps 1 and 2 at the other counterbalance spring.

    Adjusting the Lift-Arm Turnaround Position

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

    2. The lift-arm switch is located underneath the hydraulic tank and inboard of the cutting unit #5 lift arm (Figure 51).

      g375697
    3. Loosen the jam nut that secures lift-arm switch to the switch plate (Figure 52).

      g375696
    4. Adjust the lift-arm switch as follows:

      • To increase the lift-arm turnaround height, move the switch down.

      • To decrease the lift-arm turnaround height, move the switch up.

    5. Tighten the jam nut.

    Adjusting the Turf-Compensation Spring

    The turf-compensation spring (Figure 53) transfers the weight from the front roller to the rear roller. This helps to reduce a wave pattern in the turf, also known as marcelling or bobbing.

    Important: Make spring adjustments with the cutting unit mounted to the traction unit, pointing straight ahead, and lowered to the shop floor.

    1. Make sure that the hairpin is installed in the rear hole in the spring rod (Figure 53).

      Note: When servicing the cutting unit, move the hairpin to the spring-rod hole next to the turf-compensation spring.

      g003863
    2. Tighten the hex nuts on the front end of the spring rod until the compressed length of the spring is 15.9 cm (6.25 inches); refer to Figure 53.

      Note: When operating on rough terrain decrease the spring length by 13 mm (1/2 inch). Ground following will be slightly decreased.

      Note: The turf compensation setting will need to be reset if the HOC setting or the Aggressiveness of Cut setting is changed.

    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 arm (Figure 54). When the machine is functioning properly and the key switch is moved to the ON/RUN position, the diagnostic light turns on briefly to indicate the light is working properly. When a machine advisory message is displayed, the light illuminates when the message is present. When a fault message is displayed, the light blinks until the fault is resolved.

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

    Servicing the Air Cleaner

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

    Service the air cleaner filter only when the service indicator (Figure 73) requires it. Changing the air filter before it is necessary only increases the chance of dirt entering the engine when the filter is removed.

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

    1. Release the latches securing the air-cleaner cover to the air-cleaner body (Figure 73).

      g003968
    2. Remove the cover from the air cleaner body. Before removing the filter, use low pressure air (40 psi, clean and dry) to help remove large accumulations of debris packed between outside of the filter and the canister. Avoid using high pressure air which could force dirt through the filter into the intake tract.

      This cleaning process prevents debris from migrating into the intake when the filter is removed.

    3. Remove and replace the filter (Figure 74).

      Cleaning of the used element is not recommended due to the possibility of damage to the filter media. Inspect the new filter for shipping damage, checking the sealing end of the filter and the body. Do not use a damaged element. Insert the new filter by applying pressure to the outer rim of the element to seat it in the canister. Do not apply pressure to the flexible center of the filter.

    5. Move the backlap levers to the R (backlap) position (Figure 105).

      Note: Select either the front, rear, or both backlap levers to control which cutting units to backlap. When backlapping, the front cutting units all operate together, and the rear cutting units operate together.

    Lapping the Reels and Bedknife

    Danger

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

    • Never change the engine speed while backlapping.

    • Only backlap at idle engine speed.

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

    2. With the Mow/Transport lever in the MOW position, move the Enable/Disable switch to the ENABLE position. Move the Lower Mow/Lift control forward to start the backlapping operation on the designated reels.

    3. Apply lapping compound with a long-handled brush.

      Danger

      Contacting the cutting units when they are moving could cause personal injury.

      To avoid personal injury, be certain that you are clear of the cutting units before proceeding.

      Important: Never use a short-handled brush.

    4. 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 your desired speed.

    5. If you need to make an adjustment to the cutting units while backlapping, perform the following steps:

      1. Moving the Lower Mow/Raise lever rearward and press the Enable/Disable switch to DISABLE position.

      2. Shut off the engine and remove the key.

      3. Adjust to the cutting units.

      4. Repeat steps 1 through 3.

    6. Repeat steps 3 for the other cutting units that you want to backlap.

    Finishing Backlapping

    1. Moving the Lower Mow/Raise lever rearward and press the Enable/Disable switch to DISABLE position.

    2. Shut off the engine and remove the key.

    3. Move the backlap levers to the F (mow) position (Figure 106).

      Important: If you do not change backlap lever to the F (mow) position after backlapping, the cutting units will not function properly.

      g377117
    4. Lower and latch the operator’s seat; refer to Lowering the Seat.

    5. Wash all lapping compound off from the cutting units.

    6. For a better cutting edge, run a file across the front face of the bedknife after lapping.

      Note: This removes any burrs or rough edges that may have built up on the cutting edge.
