Before Operation

Before Operation Safety

General Safety

  • Never allow children or untrained people to operate or service the machine. Local regulations may restrict the age of the operator. The owner is responsible for training all operators and mechanics.

  • Become familiar with the safe operation of the equipment, operator controls, and safety signs.

  • Always shut off the engine, remove the key, wait for all moving parts to stop, and allow the machine to cool before adjusting, servicing, cleaning, or storing the machine.

  • Know how to stop the machine and shut off the engine quickly.

  • Do not operate the machine without all guards and other safety protective devices in place and functioning properly on the machine.

  • Before mowing, always inspect the machine to ensure that the cutting units are in good working condition.

  • Inspect the area where you will use the machine and remove all objects that the machine could throw.

Fuel Safety

  • Use extreme care in handling fuel. It is flammable and its vapors are explosive.

  • Extinguish all cigarettes, cigars, pipes, and other sources of ignition.

  • Use only an approved fuel container.

  • Do not remove the fuel cap or fill the fuel tank while the engine is running or hot.

  • Do not add or drain fuel in an enclosed space.

  • 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 other appliance.

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

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 Each Use/Daily procedures listed in .

    Filling the Fuel Tank

    Fuel Tank Capacity

    53 L (14 US gallons)

    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.

    Adding Fuel

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

    2. Using a clean rag, clean the area around the fuel-tank cap.

    3. Remove the cap from the fuel tank (Figure 29).

      g021210
    4. Fill the tank until the level is to the bottom of the filler neck with diesel fuel.

    5. Install fuel-tank cap tightly after filling tank.

      Note: If possible, fill the fuel tank after each use. This minimizes possible buildup of condensation inside the fuel tank.

    Breaking in the Machine

    To ensure optimum performance of the parking brake system, burnish (break in) the brakes before use. Set the forward traction speed to 6.4 km/h (4 mph) to match the reverse traction speed (all 8 spacers moved to the top of the mow-speed control). With the engine at high idle, proceed forward with the mow-speed-control stop engaged and ride the brake for 15 seconds. Proceed backward at full reverse speed and ride the brake for 15 seconds. Repeat this 5 times waiting 1 minute between each forward and reverse cycle to avoid overheating the brakes. An adjustment to the brakes may be required after break-in; refer to Adjusting the Parking Brakes.

    Bleeding the Fuel System

    You must bleed the fuel system before starting the engine if any of the following situations have occurred:

    • Initial start-up of a new machine.

    • Engine has ceased running due to lack of fuel.

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

    Danger

    Under certain conditions, diesel fuel and fuel vapors are highly flammable and explosive. A fire or explosion from fuel can burn you and others and can cause property damage.

    • Use a funnel and fill the fuel tank outdoors, in an open area, when the engine is off and is cold. Wipe up any fuel that spills.

    • Do not fill the fuel tank completely full. Add fuel to the fuel tank until the level is 6 to 13 mm (1/4 to 1/2 inch) below the bottom of the filler neck. This empty space in the tank allows the fuel to expand.

    • Never smoke when handling fuel, and stay away from an open flame or where fuel fumes may be ignited by a spark.

    • Store fuel in a clean, safety-approved container and keep the cap in place.

    1. Park the machine on a level surface and ensure that the fuel tank is at least half full.

    2. Open the hood.

    3. Open the air-bleed screw on the fuel-injection pump (Figure 30) with a 12 mm wrench.

      g003993
    4. Turn the key to the ON position. The electric fuel pump begins operation, thereby forcing air out around the air bleed screw. Leave the key in the ON position until a solid stream of fuel flows out around the screw.

    5. Tighten the screw and turn the key to the OFF position.

    Note: Normally, the engine should start after the above bleeding procedures are followed. However, if engine does not start, air may be trapped between injection pump and injectors; refer to Bleeding Air from the Fuel Injectors.

    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; substantial, slip-resistant footwear; and hearing protection. 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 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.

    • 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.

    • 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 cutting units), do the following:

      • Park the machine on level ground.

      • Disengage the cutting units and lower the attachments.

      • Engage the parking brake.

      • Shut off the engine and remove the key.

      • Wait for all moving parts 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.

      • 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.

    Starting the Engine

    Important: You must bleed the fuel system before starting the engine if you are starting the engine for the first time, the engine has shut off due to lack of fuel, or you have performed maintenance on the fuel system; refer to Bleeding the Fuel System.

    1. Sit on the seat, keep your foot off the traction pedal so that it is in NEUTRAL, engage the parking brake, set the engine-speed switch to the FAST position, and ensure that the Enable/Disable switch is in the DISABLE position.

    2. Turn the key to the ON/PREHEAT position.

      An automatic timer controls the glow plug preheat for 6 seconds.

    3. After preheating the glow plugs, turn the key to the START position.

      Crank the engine for no longer than 15 seconds. Release the key when the engine starts. If additional preheating is required, turn the key to the OFF position and then to the ON/PREHEAT position. Repeat this process as required.

    4. Run the engine at low idle speed until it warms up.

    Shutting Off the Engine

    1. Move all controls to NEUTRAL, engage the parking brake, move the throttle to the LOW IDLE position and allow the engine to reach low idle speed.

      Important: Allow the engine to idle for 5 minutes before shutting it off after a full load operation. Failure to do so may lead to trouble on a turbo-charged engine.

    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 continues to show the calculated reel speed based on blade count, mow speed, and HOC, but the new value is also displayed.

      Note: The reel speed may need to be increased or decreased to compensate for varying turf conditions.

    g031995
    g031996

    Adjusting the Lift-Arm Counterbalance

    You can adjust the counterbalance on the rear cutting-unit lift arms to compensate for different turf conditions and to maintain a uniform height of cut in the rough conditions or in areas of thatch buildup.

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

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

    2. Insert a tube or similar object onto the long spring end and pivot it around the spring actuator to the desired position (Figure 33).

      Caution

      The springs are under tension and could cause personal injury.

      Use caution when adjusting the springs.

      g019276
    3. Repeat the procedure on the other spring.

    Adjusting the Lift-Arm Turnaround Position

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

    2. The lift-arm switch is located underneath the hydraulic tank behind the front, right lift arm (Figure 34).

    3. Loosen the switch-mounting screws and move the switch down to increase the lift-arm turnaround height or move the switch up to decrease the lift-arm turnaround height (Figure 34).

      g012154
    4. Tighten the mounting screws.

    Understanding the Diagnostic Light

    The machine is equipped with a diagnostic light, which indicates if the machine detects a malfunction. The diagnostic light is located on the InfoCenter, above the display screen (Figure 35). 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 that the light is working properly. When a machine advisory message appears, the light illuminates when the message is present. When a fault message appears, the light blinks until the fault is resolved.

    g021272

    Checking the Interlock Switches

    The purpose of the interlock switches is to prevent the engine from cranking or starting unless the traction pedal is in the NEUTRAL position, the Enable/Disable switch is in the DISABLE position, and the Lower Mow/Raise control is in the NEUTRAL position. In addition, the engine should stop when you press the traction pedal while you are off the seat or if the parking brake is engaged.

    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.

    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. Turn the key to the ON position and start the machine.

    3. Locate the appropriate output function in the diagnostics menu on the InfoCenter.

    4. Sit on the seat and attempt to operate the desired function of the machine.

    Note: The appropriate outputs should change state to indicate that the ECM is turning on that function.If the correct outputs do not illuminate, verify that the required input switches are in the necessary positions to allow that function to occur. Verify the correct switch function.If the output displays are on as specified, but the machine does not function properly, this indicates a non-electrical problem. Repair the machine as necessary.

    Operating Tips

    Becoming Familiarized with the Machine

    Before mowing grass, practice operating the machine in an open area. Start and shut off the engine. Operate in forward and reverse. Lower and raise the cutting units and engage and disengage the reels. When you feel familiar with the machine, practice operating up and down slopes at different speeds.

    Understanding the Warning System

    If a warning light comes on during operation, stop the machine immediately and correct the problem before continuing operation. Serious damage could occur if you operate the machine with a malfunction.

    Mowing

    Start the engine and move the engine-speed switch to the FAST position.
