Adding Fuel

  • For best results, use only clean, fresh (less than 30 days old), unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method).

  • Ethanol: Gasoline with up to 10% ethanol (gasohol) or 15% MTBE (methyl tertiary butyl ether) by volume is acceptable. Ethanol and MTBE are not the same. Gasoline with 15% ethanol (E15) by volume is not approved for use. Never use gasoline that contains more than 10% ethanol by volume, such as E15 (contains 15% ethanol), E20 (contains 20% ethanol), or E85 (contains up to 85% ethanol). Using unapproved gasoline may cause performance problems and/or engine damage which may not be covered under warranty.

  • Do not use gasoline containing methanol.

  • Do not store fuel either in the fuel tank or fuel containers over the winter unless you use a fuel stabilizer.

  • Do not add oil to gasoline.

Danger

In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property.

  • Fill the fuel tank outdoors, in an open area, when the engine is cold. Wipe up any gasoline that spills.

  • Never fill the fuel tank inside an enclosed trailer.

  • Do not fill the fuel tank completely full. Add gasoline 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 gasoline to expand.

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

  • Store gasoline in an approved container and keep it out of the reach of children. Never buy more than a 30-day supply of gasoline.

  • Do not operate without entire exhaust system in place and in proper working condition.

Danger

In certain conditions during fueling, static electricity can be released causing a spark, which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property.

  • Always place gasoline containers on the ground away from your vehicle before filling.

  • Do not fill gasoline containers inside a vehicle or on a truck or trailer bed because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge.

  • When practical, remove gas-powered equipment from the truck or trailer and refuel the equipment with its wheels on the ground.

  • If this is not possible, then refuel such equipment on a truck or trailer from a portable container rather than from a gasoline-dispenser nozzle.

  • If you must use a gasoline-dispenser nozzle must be used, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.

Warning

Gasoline is harmful or fatal if swallowed. Long-term exposure to vapors can cause serious injury and illness.

  • Avoid prolonged breathing of vapors.

  • Keep face away from nozzle and gas tank or conditioner bottle opening.

  • Avoid contact with skin; wash off spills with soap and water.

Using Stabilizer/Conditioner

Use a fuel stabilizer/conditioner in the machine to provide the following benefits:

  • Keeps gasoline fresh during storage of 90 days or less. For longer storage, drain the fuel tank.

  • Cleans the engine while it runs

  • Eliminates gum-like varnish buildup in the fuel system, which causes hard starting

    Important: Do not use fuel additives containing methanol or ethanol.

    Add the correct amount of gas stabilizer/conditioner to the gas.

    Note: A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times.

Filling the Fuel Tank

  1. Park the machine on level ground.

  2. Shut the engine off and set the parking brake.

  3. Clean around the fuel-tank cap and remove the cap.

  4. Fill the fuel tank to the bottom of the filler neck.

    Note: Do not fill the fuel tank completely full. The empty space in the tank allows the gasoline to expand.

  5. Install the fuel-tank cap securely. Wipe up any gasoline that may have spilled.

Checking the Engine-Oil Level

Before you start the engine and use the machine, check the oil level in the engine crankcase; refer to Checking the Engine-Oil Level.

Breaking in a New Machine

New engines take time to develop full power. Mower decks and drive systems have higher friction when new, placing additional load on the engine. Allow 40 to 50 hours of break-in time for new machines to develop full power and best performance.

Operating the Parking Brake

Always set the parking brake when you stop the machine or leave it unattended. Before each use, check the parking brake for proper operation.

If the parking brake does not hold securely, adjust it; refer to Adjusting the Brakes.

Caution

Children or bystanders may be injured if they move or attempt to operate the machine while it is unattended.

Always remove the ignition key and set the parking brake when leaving the machine unattended.

Using 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.

Understanding the Safety-Interlock System

The safety-interlock system is designed to prevent the mower blades from rotating unless 1 of the following occur:

  • You move the right motion-control lever to the center, unlocked position.

  • The blade-control switch (PTO) is engaged.

    The safety-interlock system is designed to stop the mower blades if you move or release the right motion-control lever into the NEUTRAL-LOCK position.

    The hour meter has symbols to notify you when the interlock component is in the correct position. When the component is in the correct position, a triangle lights up in the corresponding square.

    g009472

    Figure 19

    1. Triangles light up when the interlock components are in the correct position.

      Note: This allows access to the bypass valves.

    3. Open the bypass valve on both pumps by turning them counterclockwise 1 to 2 turns (Figure 24).

      Note: This allows hydraulic fluid to bypass the pumps and the wheels to turn.

      Note: Rotate the bypass valves a maximum of 2 turns so that the valve does not come out of the body, causing fluid to run out.

      g012680

      Figure 24

      1. Pump-bypass valve

    4. Release the parking brake.

    5. Push the machine to the desired location.

    6. Set the parking brake.

    7. Close the bypass valves but do not overtighten them.

    8. Torque the valves to 12 to 15 N∙m (110 to 130 in-lb).

      Important: Do not start or operate the machine with the bypass valves open. Damage to system may occur.

    Transporting the Machine

    Use a heavy-duty trailer or truck to transport the machine. Ensure that the trailer or truck has all necessary brakes, lighting, and marking as required by law. Please carefully read all the safety instructions.

    1. Raise the platform of the machine before driving up onto the trailer or truck.

    2. If using a trailer, connect it to the towing vehicle and connect the safety chains.

    3. If applicable, connect the trailer brakes.

    4. Load the machine onto the trailer or truck.

    5. Shut off the engine, remove the key, set the brake, and close the fuel valve.

    6. Use the metal tie-down loops on the machine to securely fasten the machine to the trailer or truck with straps, chains, cable, or ropes (Figure 25).

      g020805

      Figure 25

      1. Traction unit tie-down loop

    Loading the Machine

    Use extreme caution when loading or unloading machines onto a trailer or a truck. Use a full-width ramp that is wider than the machine for this procedure. Back the machine up the ramp and walk it forward down the ramp (Figure 26).

    g031405

    Figure 26

    1. Back the machine up the ramp.
    2. Walk the machine down the ramp.

    Important: Do not use narrow individual ramps for each side of the machine.

    Ensure that the ramp is long enough so that the angle with the ground does not exceed 15 degrees (Figure 27). On flat ground, this requires a ramp to be at least 4 times as long as the height of the trailer or truck bed to the ground. A steeper angle may cause mower components to get caught as the machine moves from the ramp to the trailer or truck. Steeper angles may also cause the machine to tip or lose control. If you are loading the machine on or near a slope, position the trailer or truck so that it is on the down side of the slope and the ramp extends up the slope. This minimizes the ramp angle.

    Warning

    Loading a machine onto a trailer or truck increases the possibility of tip-over and could cause serious injury or death.

    • Use extreme caution when operating a machine on a ramp.

    • Use only a full-width ramp; do not use individual ramps for each side of the machine.

    • Do not exceed a 15-degree angle between the ramp and the ground or between the ramp and the trailer or truck.

    • Ensure the length of ramp is at least 4 times as long as the height of the trailer or truck bed to the ground. This will ensure that ramp angle does not exceed 15 degrees on flat ground.

    • Back the machine up ramps and walk it forward down ramps.

    • Avoid sudden acceleration or deceleration while driving the machine on a ramp, as this could cause a loss of control or a tip-over situation.

    Side Discharging or Mulching the Grass

    This mower has a hinged grass deflector that disperses clippings to the side and down toward the turf.

    Danger

    Without the grass deflector, discharge cover, or complete grass catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris. Contact with rotating mower blade(s) and thrown debris cause injury or death.

    • Do not remove the grass deflector from the mower, because the grass deflector routes material down toward the turf. If the grass deflector is ever damaged, replace it immediately.

    • Never put your hands or feet under the mower.

    • Never try to clear the discharge area or mower blades unless you release the bail and the power takeoff (PTO) is off. Rotate the ignition key to the OFF position. Also remove the key and disconnect the wire(s) off the spark plug(s).

    Adjusting the Height of Cut

    The height of cut can be adjusted from 25 to 127 mm (1 to 5 inches) in 6 mm (1/4 inch) increments.

    1. Move the height-of-cut lever to the transport position (all the way up).

    2. Rotate the pin 90 degrees and remove it from the height-of-cut bracket.

    3. Select a hole in the height-of-cut bracket corresponding to the height-of-cut desired and insert the pin (Figure 28).

    4. Push the button on top and lower the height-of-cut lever to the pin (Figure 28).
