Operation

Note: Determine the left and right sides of the machine from the normal operating position.

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 a fuel stabilizer is used.

  • 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 the entire exhaust system in place and in proper working condition.

Danger

In certain conditions during fueling, static electricity can cause 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 fuel the equipment with the wheels on the ground.

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

  • If a gasoline dispenser 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 Fuel Stabilizer/Conditioner

Use a fuel stabilizer/conditioner in the machine to keep the fuel fresh during storage of 90 days or less. If you are storing the machine for longer, drain the fuel tank; refer to Servicing the Fuel Tank.

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

Add the correct amount of fuel stabilizer/conditioner to the fuel, and follow the directions of the manufacturer.

Note: 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 it. Add regular unleaded 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 space in the tank allows the gasoline to expand. Do not fill the fuel tank completely full; refer to (Figure 7).

    g009189g027726

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.

Using the Rollover Protection System (ROPS)

Warning

To avoid injury or death from rollover: keep the roll bar in the fully raised locked position and use the seat belt.

    The following figures are only recommendations for use. Adjustments will vary by grass type, moisture content, and height of grass.

    Note: If the engine power draws down and the mower ground speed is the same, open up the baffle.

    Position A

    This is the full-rear position. The suggested use for this position is as follows.

    • Use for short, light grass-mowing conditions.

    • Use in dry conditions.

    • For smaller grass clippings.

    • Propels grass clippings farther away from the mower.

      g005832

    Position B

    Use this position when bagging. Always align it with the blower opening.

    g005833

    Position C

    This is the full open position. The suggested use for this position is as follows.

    • Use in tall, dense grass-mowing conditions.

    • Use in wet conditions.

    • Lowers the engine power consumption.

    • Allows increased ground speed in heavy conditions.

    • This position is similar to the benefits of the Toro SFS mower.

      g005834

    Positioning the Seat

    Using the Drive-Wheel-Release Valves

    Warning

    Hands may become entangled in the rotating drive components below the engine deck, which could result in serious injury.

    Stop the engine, remove the key, and allow all moving parts to stop before accessing the drive wheel release valves.

    Warning

    The engine and hydraulic drive units can become very hot. Touching a hot engine or hydraulic-drive units can cause severe burns.

    Allow the engine and hydraulic drive units to cool completely before accessing the drive wheel release valves.

    The drive wheel release valves are located in the back of each hydraulic drive unit, under the seat.

    Note: Make sure that the release valves are in the fully horizontal position when operating the machine or severe damage to the hydraulic system can occur.

    1. Disengage the PTO (blade-control switch) and turn the ignition key to off.

    2. Move the levers to the NEUTRAL-LOCK position, apply parking brake, and remove the key.

    3. Rotate the release valve levers vertically to push the machine. This allows hydraulic oil to bypass the pump enabling the wheels to turn (Figure 36).

    4. Disengage parking brake before pushing.

      g008957
    5. Rotate the release valve levers horizontally to run the machine (Figure 36).

    Using the Side Discharge

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

    Danger

    Without a 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 will cause injury or death.

    • Never 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 move the power take off (blade-control switch (PTO) to the off position, rotate the ignition key to off and remove the key.

    • Make sure the grass deflector is in the down position.

    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. Knowing this information could help you, your family, pets, or bystanders avoid injury.

    Warning

    Driving on the street or roadway without turn signals, lights, reflective markings, or a slow-moving vehicle emblem is dangerous and can lead to accidents causing personal injury.

    Do not drive the machine on a public street or roadway.

    To transport the machine:

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

    2. If applicable, connect the trailer brakes.

    3. Load the machine onto the trailer or truck.

    4. Stop the engine, remove the key, set the brake, and close the fuel valve.

    5. 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 37).

      g027338

    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 up ramps and drive forward down ramps (Figure 38).

    g028043

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

    Ensure the ramp is long enough so that the angle with the ground does not exceed 15 degrees (Figure 39). On flat ground, this requires a ramp to be at least four times (4X) 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 unit moves from the ramp to the trailer or truck. Steeper angles may also cause the machine to tip or lose control. If loading 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 will minimize 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.

    • Ensure that the ROPS is in the up position and use the seat belt when loading or unloading the machine. Ensure that the ROPS will clear the top of an enclosed trailer.

    • 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 four times (4X) 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 up ramps and drive 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.

    g027996

    Operating Tips

    Using the Fast Throttle Setting

    For best mowing and maximum air circulation, operate the engine at the FAST throttle position. Air is required to thoroughly cut grass clippings, so do not set the height-of-cut so low as to totally surround the mower by uncut grass. Always try to have 1 side of the mower free from uncut grass, which allows air to be drawn into the mower.

    Cutting a Lawn for the First Time

    Cut grass slightly longer than normal to ensure that the cutting height of the mower does not scalp any uneven ground. However, the cutting height you have used in the past is generally the best 1 to use. When cutting grass longer than 15.24 cm (6 inches) tall, you may want to cut the lawn twice to ensure an acceptable quality of cut.

    Cutting a Third of the Grass Blade

    It is best to cut only about 1/3 of the grass blade. Cutting more than that is not recommended unless grass is sparse, or it is late fall when grass grows more slowly.

    Alternating the Mowing Direction

    Alternate the mowing direction to keep the grass standing straight. This also helps disperse clippings, which enhances decomposition and fertilization.

    Mowing at Correct Intervals

    Normally, mow every 4 days. However, grass grows at different rates at different times. To maintain the same cutting height, which is a good practice, mow more often in early spring. As the grass growth rate slows in mid-summer, mow less frequently. If you cannot mow for an extended period, first mow at a high cutting height; then mow again 2 days later at a lower height setting.

    Adjusting the Cutting Speed

    To improve cut quality, use a slower ground speed in certain conditions.

    Avoiding Cutting Too Low

    If the cutting width of the mower is wider than the mower that you previously used, raise the cutting height to ensure that uneven turf is not cut too short.

    Cutting Long Grass

    If the grass is ever allowed to grow slightly longer than normal, or if it contains a high degree of moisture, raise the cutting height higher than usual and cut the grass at this setting. Then cut the grass again using the lower, normal setting.

    Stopping

    If you must stop the forward motion of the machine while mowing, a clump of grass clippings may drop onto your lawn. To avoid this, move onto a previously cut area with the blades engaged.

    Keeping the Underside of the Mower Clean

    Clean clippings and dirt from the underside of the mower after each use. If grass and dirt build up inside the mower, the cutting quality eventually becomes unsatisfactory.

    Maintaining the Blade

    Maintain a sharp blade throughout the cutting season, because a sharp blade cuts cleanly without tearing or shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease. Check the cutter blades daily for sharpness and for any wear or damage. File down any nicks and sharpen the blades as necessary. If a blade is damaged or worn, replace it immediately with a genuine Toro replacement blade.

    18. Measure until all 4 sides are the correct height.

    19. Tighten all the jam nuts on the deck-lift arm assemblies.

    20. Lower the discharge chute.

    Servicing the Cutting Blades

    Maintain sharp blades throughout the cutting season, because sharp blades cut cleanly without tearing or shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease.

    Check the cutter blades daily for sharpness, and for any wear or damage. File down any nicks and sharpen the blades as necessary. If a blade is damaged or worn, replace it immediately with a genuine Toro replacement blade. For convenient sharpening and replacement, you may want to keep extra blades on hand.

    Warning

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

    • Inspect the blades periodically for wear or damage.

    • Replace a worn or damaged blade.

    Before Inspecting or Servicing the Blades

    1. Park the machine on a level surface, Disengage the blade-control switch (PTO), and set the parking brake.

    2. Turn the ignition key to off. Remove the key, and disconnect the spark plug wires from the spark plugs.

    2. If the edges are not sharp or have nicks, remove and sharpen the blade; refer to Sharpening the Blades and Installing the Blades.

    3. Inspect the blades, especially in the curved area.

    4. If you notice any cracks, wear, or a slot forming in this area, immediately install a new blade (Figure 97).

      g006530

    Checking for Bent Blades

    1. Disengage the blade-control switch (PTO), move the motion-control levers to the NEUTRAL-LOCK position, and set the parking brake.

    2. Stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.

    3. Rotate the blades until the ends face forward and backward (Figure 98).

    4. Measure from a level surface to the cutting edge, position A, of the blades (Figure 98).

      g000975
    5. Rotate the opposite ends of the blades forward.

    6. Measure from a level surface to the cutting edge of the blades at the same position as in step 4.

      Note: The difference between the dimensions obtained in steps 4 and 5 must not exceed 3 mm (1/8 inch).

      Note: If this dimension exceeds 3 mm (1/8 inch), the blade is bent and must be replaced.

      Warning

      A blade that is bent or damaged could break apart and could seriously injure or kill you or bystanders.

      • Always replace bent or damaged blade with a new blade.

      • Do not file or create sharp notches in the edges or surfaces of the blade.

    Removing the Blades

    Replace a blade if it hits an object, if the blade is out of balance, or if the blade is bent. To ensure optimum performance and continued safety conformance of the machine, use genuine Toro replacement blades. Replacement blades made by other manufacturers may result in nonconformance with safety standards.

    1. Hold the blade end using a rag or a thickly padded glove.

    2. Remove the blade bolt, curved washer, and blade from the spindle shaft (Figure 99).

      g004536

    Sharpening the Blades

    Warning

    When sharpening blades, pieces of a blade could be thrown and cause serious injury.

    Wear proper eye protection when sharpening blades.

    1. Use a file to sharpen the cutting edge at both ends of the blade (Figure 100).

      Note: Maintain the original angle.

      Note: The blade retains balance if you remove the same amount of material from both cutting edges.

      g000276
    2. Check the balance of the blade by putting it on a blade balancer (Figure 101).

      Note: If the blade stays in a horizontal position, the blade is balanced and ready to use.

      g000277
    3. If the blade is not balanced, file some metal off the end of the sail area only (Figure 99).

    4. Repeat this procedure until the blade is balanced.

    Installing the Blades

    1. Install the blade onto the spindle shaft (Figure 102).

      Important: The curved part of the blade must point upward toward the inside of the mower to ensure proper cutting.

    2. Install the spring disk and blade bolt (Figure 102).

      Note: Install the spring-disk cone toward the bolt head.

    3. Torque the blade bolt to 115 to 150 N∙m (85 to 110 ft-lb).

      g004536

    Removing the Mower Deck

    Before servicing or removing the mower deck, lock out the spring-loaded deck arms.

    Warning

    Deck lift arm assemblies have stored energy. Removing the deck with out releasing the stored energy can cause serious injury or death.

    Do not attempt to disassemble the deck from the front frame without locking out the stored energy.

    1. Stop the engine, wait for all moving parts to stop, and remove the key. Engage the parking brake.

    2. Remove the height-adjustment pin and lower the deck to the ground.

    3. Place the height-adjustment pin in the 7.6 cm (3 inch) cutting-height location.

      Note: This locks the deck lift arms in the lowest position when the deck is removed and the stored energy in the deck spring is released.

    4. Remove the belt covers.

    5. Lift up the floor pan and insert a ratchet into the square hole in the deck idler (Figure 103).

    6. Rotate the deck idler clockwise and remove the mower belt (Figure 103).

      g009038
    7. Remove and retain the hardware on both sides of the deck as shown in Figure 104 or Figure 105.
