Before Operation

Before Operation Safety

General Safety

  • Evaluate the terrain to determine what accessories and attachments are needed to properly and safely perform the job. Only use accessories and attachments approved by Toro.

  • Inspect the area where the equipment is to be used and remove all rocks, toys, sticks, wires, bones, and other foreign objects. These can be thrown or interfere with the operation of the machine and may cause personal injury to the operator or bystanders.

  • Wear appropriate personal protective equipment such as safety glasses, substantial slip-resistant footwear, and hearing protection. Tie back long hair and avoid loose clothing and loose jewelry which may get tangled in moving parts.

    Caution

    This machine produces sound levels in excess of 85 dBA at the operator’s ear and can cause hearing loss through extended periods of exposure.

    Wear hearing protection when operating this machine.

  • Check that the operator presence controls, safety switches, and shields are attached and functioning properly. Do not operate unless they are functioning properly.

  • Do not operate the mower when people, especially children, or pets are in the area. Stop the machine and attachment(s) if anyone enters the area.

  • Do not operate the machine without the entire grass collection system, discharge deflector, or other safety devices in place and in proper working condition. Grass catcher components are subject to wear, damage and deterioration, which could expose moving parts or allow objects to be thrown. Frequently check for worn or deteriorating components and replace them with the manufacturer’s recommended parts when necessary.

Fuel Safety

Use extreme care when handling fuel.

Danger

In certain conditions fuel is extremely flammable and vapors are explosive.

A fire or explosion from fuel can burn you, others, and cause property damage.

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

  • Never refill the fuel tank or drain the machine indoors or inside an enclosed trailer.

  • Do Not fill the fuel tank completely full. Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows fuel to expand. Overfilling may result in fuel leakage or damage to the engine or emission system.

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

  • Store fuel in an approved container and keep it out of the reach of children.

  • Add fuel before starting the engine. Never remove the cap of the fuel tank or add fuel when engine is running or when the engine is hot.

  • If fuel is spilled, Do Not attempt to start the engine. Move away from the area of the spill and avoid creating any source of ignition until fuel vapors have dissipated.

  • 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 fuel vapors. A fire or explosion from fuel can burn you and others and cause property damage.

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

  • Do Not fill fuel 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 fuel dispenser nozzle.

  • If a fuel 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. Do Not use a nozzle lock open device.

Warning

Fuel is harmful or fatal if swallowed. Long-term exposure to vapors has caused cancer in laboratory animals. Failure to use caution may cause serious injury or illness.

  • Avoid prolonged breathing of vapors.

  • Keep face away from nozzle and gas tank/container opening.

  • Keep away from eyes and skin.

  • Never siphon by mouth.

Caution

Fuel tank vent is located inside the roll bar tube. Removing or modifying the roll bar could result in fuel leakage and violate emissions regulations.

  • Do Not remove roll bar.

  • Do Not weld, drill, or modify roll bar in any way.

To help prevent fires:

  • Keep engine and engine area free from accumulation of grass, leaves, excessive grease or oil, and other debris which can accumulate in these areas.

  • Clean up oil and fuel spills and remove fuel soaked debris.

  • Allow the machine to cool before storing the machine in any enclosure. Do Not store near flame or any enclosed area where open pilot lights or heat appliances are present.

Performing Daily Maintenance

Before starting the machine each day, perform the Each Use/Daily procedures listed in .

Adding Fuel

Recommended Fuel

The engine runs on clean, fresh diesel fuel with a minimum octane rating of 40. Purchase fuel in quantities that can be used within 30 days to ensure fuel freshness.

Use summer-grade diesel fuel (No. 2-D) at temperatures above -7°C (20°F) and winter-grade diesel fuel (No. 1-D or No. 1-D/2-D blend) below -7°C (20°F). Use of winter-grade diesel fuel at lower temperatures provides lower flash point and pour point characteristics, therefore easing startability and lessening chances of chemical separation of the fuel due to lower temperatures (wax appearance, which may plug filters).

Using summer-grade diesel fuel above -7°C (20°F) contributes toward longer life of the pump components.

Important: Do not use kerosene or gasoline instead of diesel fuel. Failure to observe this caution will damage 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 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 blend in cold weather.

  • Monitor seals, hoses, gaskets in contact with fuel as they may degrade over time.

  • Fuel filter plugging may be expected for a time after converting to biodiesel blends.

  • Contact your distributor for more information on biodiesel.

Filling the Fuel Tank

  1. Park the machine on a level surface.

  2. Engage the parking brake.

  3. Shut off the engine and remove the key.

  4. Clean around the fuel-tank cap.

  5. Fill the fuel tank to the bottom of the filler neck (Figure 8).

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

    g027726

Switching the Fuel Tanks

Important: Do not allow the machine to run out of fuel, as this can damage the machine.

The fuel-selector valve is located behind the left side of the seat.

The machine has 2 fuel tanks: 1 tank is on the left side and 1 is on the right side. Each tank connects to the fuel-selector valve. From there, a common fuel line leads to the engine (Figure 9).

To use the left fuel tank, rotate the fuel-selector valve to the left. To use the right fuel tank, rotate the fuel-selector valve to the right (Figure 9).

Close the fuel-selector valve before transporting or storing the machine.

g000962

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.

Ensure that the seat is secured to the machine.

Warning

There is no rollover protection when the roll bar is in the down position.

  • Lower the roll bar only when absolutely necessary.

  • Do not wear the seat belt when the roll bar is in the down position.

  • Drive slowly and carefully.

  • Raise the roll bar as soon as clearance permits.

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

Lowering the Roll Bar

Important: Lower the roll bar only when absolutely necessary.

  1. Remove the hairpin cotters and remove the 2 pins (Figure 11).

  2. Lower the roll bar to the down position (Figure 10).

    Note: There are 2 down positions; refer to Figure 10.

  3. Install the 2 pins and secure them with the hairpin cotters (Figure 11).

    g004954

    Important: Ensure that you secure the rear part of the seat with the seat latch.

    g004955

Using the Safety-Interlock System

Warning

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 engine from starting unless the following occurs:

  • The parking brake is engaged.

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

  • The motion-control levers are in the NEUTRAL-LOCK position.

The safety-interlock system also is designed to shut off the engine when the motion-control levers are moved from the NEUTRAL-LOCK position with the parking brake engaged or if you rise from the seat when the PTO is engaged.

The hour meter has indicators to notify the user when the interlock component is in the correct position. When the component is in the correct position, an indicator displays on the screen.

    • Allow engine parts, especially the muffler, to cool before touching.

    • Remove accumulated debris from muffler and engine area.

    Warning

    Engine exhaust contains carbon monoxide, which is an odorless deadly poison that can kill you.

    Do Not run engine indoors or in a small confined area where dangerous carbon monoxide fumes can collect.

    • The owner/user can prevent and is responsible for accidents or injuries occurring to himself or herself, other people or property.

    • This mower was designed for one operator only. Do not carry passengers and keep all others away from machine during operation.

    • Do Not operate the machine under the influence of alcohol or drugs.

    • Operate only in daylight or good artificial light.

    • Lightning can cause severe injury or death. If lightning is seen or thunder is heard in the area, Do Not operate the machine; seek shelter.

    • Use extra care while operating with accessories or attachments, such as grass collection systems. These can change the stability of the machine and cause a loss of control. Follow directions for counter weights if required.

    • Keep away from holes, ruts, bumps, rocks, and other hidden hazards. Use care when approaching blind corners, shrubs, trees, tall grass or other objects that may hide obstacles or obscure vision. Uneven terrain could overturn the machine or cause the operator to lose their balance or footing.

    • Be sure all drives are in neutral and parking brake is engaged before starting engine. Use seat belts with the roll bar in the raised and locked position.

    • Start the engine carefully according to instructions with feet well away from the blades.

    • Never operate the mower with damaged guards, shields, or covers. Always have safety shields, guards, switches and other devices in place and in proper working condition.

    • Keep clear of the discharge opening at all times. Never mow with the discharge door raised, removed or altered unless there is a grass collection system or mulch kit in place and working properly.

    • Keep hands and feet away from moving parts. If possible, Do Not make adjustments with the engine running.

      Warning

      Hands, feet, hair, clothing, or accessories can become entangled in rotating parts. Contact with the rotating parts can cause traumatic amputation or severe lacerations.

      • Do Not operate the machine without guards, shields, and safety devices in place and working properly.

      • Keep hands, feet, hair, jewelry, or clothing away from rotating parts.

    • Never raise the deck with blades running.

    • Be aware of the mower discharge path and direct discharge away from others. Avoid discharging material against a wall or obstruction as the material may ricochet back toward the operator. Stop the blades, slow down, and use caution when crossing surfaces other than grass and when transporting the mower to and from the area to be mowed.

    • Be alert, slow down and use caution when making turns. Look behind and to the side before changing directions. Do Not mow in reverse unless absolutely necessary.

    • Do Not change the engine governor setting or overspeed the engine.

    • Park the machine on level ground. Shut off the engine and wait for all moving parts to stop.

      • Before checking, cleaning or working on the mower.

      • After striking a foreign object or abnormal vibration occurs (inspect the mower for damage and make repairs before restarting and operating the mower).

      • Before clearing blockages.

      • Whenever you leave the mower. Do Not leave a running machine unattended.

    • Stop engine, wait for all moving parts to stop:

      • Before refueling.

      • Before dumping the grass catcher.

      • Before making height adjustments.

    • Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the machine and the mowing activity. Never assume that children will remain where you last saw them.

      • Keep children out of the mowing area and under the watchful care of another responsible adult, not the operator.

      • Be alert and turn the machine off if children enter the area.

      • Before and while backing or changing direction, look behind, down, and side-to-side for small children.

      • Never allow children to operate the machine.

      • Do Not carry children, even with the blades shut off. Children could fall off and be seriously injured or interfere with the safe operation of the machine. Children that have been given rides in the past could suddenly appear in the working area for another ride and be run over or backed over by the machine.

    Slope Safety

    • Slopes are a major factor related to loss of control and rollover accidents, which can result in severe injury or death. The operator is responsible for safe slope operation. Operating the machine on any slope requires extra caution. Before using the machine on a slope, the operator must:

      • Review and understand the slope instructions in the manual and on the machine.

      • Use an angle indicator to determine the approximate slope angle of the area.

      • Never operate on slopes greater than 15 degrees.

      • Evaluate the site conditions of the day to determine if the slope is safe for machine operation. Use common sense and good judgment when performing this evaluation. Changes in the terrain, such as moisture, can quickly affect the operation of the machine on a slope.

    • Identify hazards at the base of the slope. Do Not operate the machine near drop offs, ditches, embankments, water or other hazards. The machine could suddenly roll over if a wheel goes over the edge or the edge collapses. Keep a safe distance (twice the width of the machine) between the machine and any hazard. Use a walk behind machine or a hand trimmer to mow the grass in these areas.

      g221745
    • Avoid starting, stopping or turning the machine on slopes. Avoid making sudden changes in speed or direction; turn slowly and gradually.

    • Do Not operate a machine under any conditions where traction, steering or stability is in question. Be aware that operating the machine on wet grass, across slopes or downhill may cause the machine to lose traction. Loss of traction to the drive wheels may result in sliding and a loss of braking and steering. The machine can slide even if the drive wheels are stopped.

    • Remove or mark obstacles such as ditches, holes, ruts, bumps, rocks or other hidden hazards. Tall grass can hide obstacles. Uneven terrain could overturn the machine.

    • Use extra care while operating with accessories or attachments, such as grass collection systems. These can change the stability of the machine and cause a loss of control. Follow directions for counter weights.

    • If possible, keep the deck lowered to the ground while operating on slopes. Raising the deck while operating on slopes can cause the machine to become unstable.

    Rollover Protection System (ROPS) Safety

    A Rollover Protection System (roll bar) is installed on the machine.

    Warning

    There is no rollover protection when the roll bar is down. Wheels dropping over edges, ditches, steep banks, or water can cause rollovers, which may result in serious injury, death or drowning.

    • Do Not remove the ROPS.

    • Keep the roll bar in the raised and locked position and use seat belt.

    • Lower the roll bar only when absolutely necessary.

    • Do Not wear seat belt when the roll bar is down.

    • Drive slowly and carefully.

    • Raise the roll bar as soon as clearance permits.

    • Be certain that the seat belt can be released quickly in the event of an emergency.

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

    • In the event of a rollover, take the unit to an Authorized Service Dealer to have the ROPS inspected.

    • Replace a damaged ROPS. Do Not repair or revise.

    • Any accessories, alterations, or attachments added to the ROPS must be approved by Toro.

    g008946

    Starting the Engine in Normal Weather

    Important: Use starting cycles of no more than 30 seconds per minute to avoid overheating the starter motor.

    Note: Additional starting cycles may be required when starting the engine for the first time after the fuel system has been completely without fuel.

    g032593

    Starting the Engine in Cold Weather (Below 23°F or -5°C)

    Use the correct engine oil for the starting temperature; refer to Engine-Oil Specifications.

    Important: Use starting cycles of no more than 30 seconds per minute to avoid overheating the starter motor.

    Note: Do not use fuel left over from the summer. Use only fresh winter-grade diesel fuel.

    g032594

    Shutting Off the Engine

    Caution

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

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

    g032595

    Important: Make sure that the fuel-shutoff valve is closed before transporting or storing the machine, as fuel leakage may occur. Engage the parking brake before transporting. Make sure that you remove the key as the fuel pump may run and cause the battery to lose charge.

    Using the Motion-Control Levers

    g004532

    Driving the Machine

    The drive wheels turn independently, powered by hydraulic motors on each axle. You can turn 1 side in reverse while you turn the other forward, causing the machine to spin rather than turn. This greatly improves the machine maneuverability but may require some time for you to adapt to how it moves.

    The throttle control regulates the engine speed as measured in rpm (revolutions per minute). Place the throttle control in the FAST position for best performance. Always operate in the full throttle position when mowing.

      g008953

    Using the Side Discharge

    Machines with Side Discharge Only

    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 a 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 deck 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 deck.

    • Never try to clear the discharge area or mower blades unless you move the blade-control switch (PTO) to the OFF position, rotate the key switch to the OFF position, and remove the key from the key switch.

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

    Adjusting the Height of Cut

    Adjust the height of cut from 38 to 127 mm (1-1/2 to 5 inches) in 6 mm (1/4 inch) increments by moving the clevis pin into different hole locations.

    1. Raise the height-of-cut lever to the TRANSPORT position (also the 127 mm (5 inch) cutting-height position) (Figure 28).

      g009568
    2. To adjust, remove the pin from the height-of-cut bracket (Figure 28).

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

    4. Move the lever to the selected height.

    Adjusting the Anti-Scalp Rollers

    Machines with Side Discharge

    Whenever you change the height-of-cut, adjust the height of the anti-scalp rollers.

    1. Park the machine on a level surface, disengage the blade-control switch, and engage the parking brake.

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

    3. Adjust the anti-scalp rollers as shown in Figure 29, Figure 30, and Figure 31.

    Adjusting the Flow Baffle Knob

    For Machines with Side Discharge

    This procedure applies only to machines with the flow baffle knob. Certain models have nuts and bolts instead of the flow baffle knob that you can adjust the same way.

    You can adjust the mower discharge flow for different types of mowing conditions. Position the knob and baffle to give the best quality of cut.

    1. Park the machine on a level surface, disengage the blade-control switch, and engage the parking brake.

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

    3. Loosen the knob.

    4. Slide the knob to the desired position.

    5. Tighten the knob.

    Positioning the Flow Baffle

    For Machines with Side Discharge

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

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

    Position A

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

    • Short, light grass mowing conditions

    • Dry conditions

    • Smaller grass clippings

    • Propels grass clippings farther away from the mower

      g295810

    Position B

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

    g295811

    Position C

    This is the fully-forward position. The suggested use for this position is as follows:

    • Tall, dense grass mowing conditions

    • Wet conditions

    • Lowers the engine-power consumption

    • Allows increased ground speed in heavy conditions

      g295812

    Operating with the Overheat Sensor

    This machine has a sensor that turns off the mower deck when the engine overheats. When the engine overheats, the audible alarm and light alarm turns on along with the mower deck turning off.

    If the mower deck turns off automatically because of overheating, you will be able to drive the machine to a safe area or to a truck or trailer.

    If the machine overheats, ensure that the area around the engine and radiator is clear of any debris. Shut off the engine and allow it to cool before you engage the mower deck. If the engine continues to overheat, take your machine to an Authorized Service Dealer.

    Operating Tips

    Using the Fast Throttle Setting

    For best mowing and maximum air circulation, operate the engine at the FAST 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 deck in uncut grass. Always try to have 1 side of the mower deck free from uncut grass, which allows air to be drawn into the mower deck.

    Cutting a Lawn for the First Time

    Cut grass slightly longer than normal to ensure that the cutting height of the mower deck 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 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 a third 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

    Grass grows at different rates at different times of the year. To maintain the same cutting height, 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.

    Using a Slower Cutting Speed

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

    Avoiding Cutting Too Low

    When mowing uneven turf, raise the cutting height to avoid scalping the turf.

    Stopping the Machine

    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 or you can disengage the mower deck while moving forward.

    Keeping the Underside of the Mower Deck Clean

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

    Maintaining the Blade(s)

    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 mower blades after each use 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.

    After Operation

    After Operation Safety

    General Safety

    • Park machine on level ground, disengage drives, set parking brake, stop engine, and remove key. Wait for all movement to stop and allow the machine to cool before adjusting, cleaning, repairing, or storing. Never allow untrained personnel to service machine.

    • Clean the machine as stated in the Maintenance section. Keep engine and engine area free from accumulation of grass, leaves, excessive grease or oil, and other debris which can accumulate in these areas. These materials can become combustible and may result in a fire.

    • Frequently check for worn or deteriorating components that could create a hazard. Tighten loose hardware.

    Using the Fuel-Shutoff Valve

    The fuel-shutoff valve is located under the seat. Move the seat forward to access it.

    Mower Deck Maintenance

    Blade Safety

    A worn or damaged blade can break, and a piece of the blade could be thrown toward you or bystanders, resulting in serious personal injury or death. Trying to repair a damaged blade may result in discontinued safety certification of the product.

    • Inspect the blades periodically for wear or damage.

    • Use care when checking the blades. Wrap the blades or wear gloves, and use caution when servicing the blades. Only replace or sharpen the blades; never straighten or weld them.

    • On multi-bladed machines, take care as rotating 1 blade can cause other blades to rotate.

    Servicing the Cutting Blades

    To ensure a superior quality of cut, keep the blades sharp. For convenient sharpening and replacement, you may want to keep extra blades on hand.

    Before Inspecting or Servicing the Blades

    1. Park the machine on a level surface, disengage the blade-control switch, and engage the parking brake.

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

    Inspecting the Blades

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Inspect the blades.
    1. Inspect the cutting edges (Figure 100).

    2. If the edges are not sharp or have nicks, remove and sharpen the blade; refer to Sharpening 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 100).

      g006530

    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.

    2. While wearing thickly padded gloves, or other adequate hand protection, slowly rotate the blade into a position that allows you to measure the distance between the cutting edge and the level surface the machine is on (Figure 101).

      g014972
    3. Measure from the tip of the blade to the flat surface (Figure 102).

      g014973
    4. Rotate the same blade 180 degrees so that the opposing cutting edge is now in the same position (Figure 103).

      g014974
    5. Measure from the tip of the blade to the flat surface (Figure 104).

      Note: The variance should be no more than 3 mm (1/8 inch).

      g014973
      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 blade, and the dimension obtained continues to exceed 3 mm (1/8 inch), the blade spindle could be bent. Contact an Authorized Service 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

    Replace the blades if they hit a solid object, or if the blade is out of balance or bent.

    1. Place a wrench on the flat of the spindle shaft or hold the blade end using a rag or thickly padded glove.

    2. Remove the blade bolt, bushing, and blade from the spindle shaft (Figure 105).

      g295816

    Sharpening the Blades

    1. Use a file to sharpen the cutting edge at both ends of the blade (Figure 106).

      Note: Maintain the original angle.

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

      g000552
    2. Check the balance of the blade by putting it on a blade balancer (Figure 107).

      Note: If the blade stays in a horizontal position, the blade is balanced and can be used.

      Note: If the blade is not balanced, file some metal off the end of the sail area only (Figure 106).

      g000553
    3. Repeat this procedure until the blade is balanced.

    Installing the Blades

    1. Install the bushing through the blade with the bushing flange on the bottom (grass) side of the blade (Figure 108).

      g255205
    2. Install the bushing/blade assembly into the spindle shaft (Figure 109).

      g298850
    3. Apply copper-based lubricant or grease to the threads of the blade bolt as needed to prevent seizing. Install the blade bolt finger-tight.

    4. Place a wrench on the flat of the spindle shaft and torque the blade bolt to 75 to 81 N∙m (55 to 60 ft-lb).
