Product Overview

g028266

Become familiar with all the controls before you start the engine and operate the machine (Figure 5).

g028267

Ignition Switch

The ignition switch has three positions: Start, Run and Off. The key will turn to Start and move back to Run upon release. Turning the key to the Off position will stop the engine; however, always remove the key when leaving the machine to prevent the engine from accidentally starting (Figure 5).

Throttle Control

The throttle control is variable between Fast and Slow. Moving throttle lever forward will increase engine speed and moving throttle lever to the rear will decrease engine speed. Moving the throttle forward into the detent is full throttle (Figure 5).

Choke

Use the choke to start a cold engine. Pull the choke knob up to engage it. Push down on the choke knob to disengage it.

Blade-Control Switch (Power Take-Off)

The blade-control switch, represented by a power take-off (PTO) symbol, engages and disengages power to the mower blades (Figure 5).

Hour Meter

The hour meter records the number of hours the blades have operated. It operates when the blade-control switch (PTO) is engaged. Use these times for scheduling regular maintenance (Figure 5).

Fuel Gauge

The fuel window located below the operator position can be used to verify the level of gasoline in the tank (Figure 6).

Motion-Control Levers

The motion-control levers are speed sensitive controls of independent wheel motors. Moving a lever forward or backward turns the wheel on the same side forward or in reverse; wheel speed is proportional to the amount the lever is moved. Move the control levers outward from the center to the neutral-lock position and before exiting the machine (Figure 4). Always position the motion-control levers into the neutral-lock position when you stop the machine or leave it unattended.

Parking-Brake Lever

The parking brake lever is located on left side of the console (Figure 4). The brake lever engages a parking brake on the drive wheels. Pull the lever up and rearward to engage the brake. Push the lever forward and down to disengage the brake.

Foot Pedal Deck Lift System

The foot pedal deck lift system allows the operator to lower and raise the deck from the seated position. The operator can use the foot pedal to lift the deck briefly to avoid obstacles or lock the deck in the highest height-of-cut or transport position (Figure 4).

Height-of-Cut Lever

The height-of-cut lever works with the foot pedal to lock the deck in a specific cutting height. Only adjust the height of cut while machine is not moving (Figure 4).

Attachments/Accessories

A selection of Toro approved attachments and accessories is available for use with the machine to enhance and expand its capabilities. Contact your Authorized Service Dealer or Distributor or go to www.Toro.com for a list of all approved attachments and accessories.

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 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 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 opening.

  • Keep gas away from eyes and skin.

Using Stabilizer/Conditioner

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

  • Fuel stabilizer/conditioner keeps gasoline fresh during storage of 90 days or less. When storing the machine for longer periods, drain the fuel system.

  • It cleans the engine while it runs

  • It 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.

Using the Fuel Gauge

Use the fuel window below the operator to verify the level of gasoline before filling the tank (Figure 6).

g020318

Filling the Fuel Tank

Make sure the engine is shut off and the motion controls are in the park position.

Important: Do not overfill fuel tank. Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows the fuel to expand. Overfilling may result in fuel leakage or damage to the engine or emission system.

  1. Clean around the fuel tank cap and remove the cap.

    Note: You can use the fuel window below the operating position verify the presence of gasoline before filling the tank (Figure 6).

  2. Slowly add regular, unleaded gasoline until the fuel reaches the base of the filler neck Figure 7.

    g027637
  3. Install the fuel tank cap securely and tighten until it “clicks.” 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.

Think Safety First

Please carefully read all of the safety instructions and decals in the safety section. Knowing this information could help you, your family, pets or bystanders avoid injury.

Danger

Mowing on wet grass or steep slopes can cause sliding and loss of control.

Wheels dropping over edges can cause rollovers, which may result in serious injury, death or drowning.

A loss of traction is a loss of steering control.

To avoid loss of control and possibility of rollover:

  • Do not mow near drop-offs or near water.

  • Do not mow slopes greater than 15 degrees.

  • Reduce speed and use extreme caution on slopes.

  • When mowing slopes, gradually work from lower to higher areas on the incline.

  • Avoid sudden turns or rapid speed changes.

  • Turn up, into an incline when changing directions on slopes. Turning down the slope reduces traction.

  • Attachments change the handling characteristics of the machine. Use extra caution when using attachments with the machine.

g015033

Using the Rollover Protection System (ROPS)

Warning

To avoid injury or death from rollover: keep the roll bar installed and use the seat belt.

Warning

There is no rollover protection when the roll bar is removed.

  • Drive slowly and carefully.

  • Check carefully for overhead clearances (i.e. branches, doorways, electrical wires) before driving under any objects and do not contact them.

    • 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 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. Tie down the machine near the front caster wheels and the rear bumper (Figure 28).

      g027708

    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 29).

    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 30). 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 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.

    Operating Tips

    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 one 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 the cutting height of the mower does not scalp any uneven ground. However, the cutting height used in the past is generally the best one 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.

    Cut 1/3 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 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 four days. But remember, grass grows at different rates at different times. So 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 two days later at a lower height setting.

    Cutting Speed

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

    Avoid Cutting Too Low

    If the cutting width of the mower is wider than the mower 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 the Machine

    If you must stop the machine's forward motion 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.

    Keep 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, cutting quality will eventually become 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.

    Mower Deck Maintenance

    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 into the operator's or bystander's area, resulting in serious personal injury or death.

    • Inspect the blade 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.

    Checking for Bent Blades

    Note: The machine must be on a level surface for the following procedure.

    1. Raise the mower deck to the highest height-of-cut position; also considered the 'transport' position.

    2. While wearing thickly padded gloves or other adequate hand protection slowly rotate blade to be measured into a position that allows effective measurement of the distance between the cutting edge and the level surface the machine is on.

      g014972
    3. Measure from the tip of the blade to the flat surface here.

      g014973
    4. Rotate the same blade 180 degrees so that the opposing cutting edge is now in the same position.

      g014974
    5. Measure from the tip of the blade to the flat surface here. The variance should be no more than 3 mm (1/8 inch).

      g014973

      Warning

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

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

      • Never file or create sharp notches in the edges or surfaces of the blade.

      1. If the difference between A and B is greater than 3 mm (1/8 inch) replace the blade with a new blade. Refer to Removing the Blades and Installing the Blades.

        Note: If a bent blade is replaced with a new one and the dimension obtained continues to exceed 3 mm (1/8 inch), the blade spindle could be bent. Contact an Authorized Toro Dealer for service.

      2. If the variance is within constraints, move to the next blade..

    6. Repeat this procedure on each blade.

    Removing the Blades

    Blades must be replaced if a solid object is hit, if the blade is out of balance or 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 non-conformance with safety standards.

    Sharpening the Blades

    Warning

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

    Wear proper eye protection when sharpening blade.

    1. Use a file to sharpen the cutting edge at both ends of the blade (Figure 59).

      Note: Maintain the original angle. The blade retains its balance if the same amount of material is removed from both cutting edges.

      g000276
    2. Check the balance of the blade by putting it on a blade balancer (Figure 60).

      Note: If the blade stays in a horizontal position, the blade is balanced and can be used. If the blade is not balanced, file some metal off the end of the sail area only (Figure 58). Repeat this procedure until the blade is balanced.

      g000277

    Installing the Blades

    1. Install the blade onto the spindle shaft (Figure 58).

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

    2. Install the spring disk and blade bolt (rotating it clockwise).

      Note: The spring disk cone must be installed toward the bolt head (Figure 58).

    3. Torque the blade bolt to 135-150 N-m (100-110 ft-lb).

    Leveling the Mower Deck

    Ensure the mower deck is level any time you install the mower or when you see an uneven cut on your lawn.

    The mower deck must be checked for bent blades prior to leveling; any bent blades must be removed and replaced. Refer to the, Checking for Bent Blades, procedure before continuing.

    The mower deck must be leveled side-to-side first then the front to rear slope can be adjusted.

    Requirements:

    Checking Side-to-Side Level
