Before Operation

Before Operation 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.

Pre-Start

Fill fuel tank on level ground. See Fuel Recommendations in the Specifications section for additional gasoline information.

Do Not add oil to gasoline.

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

Make sure you understand the controls, their locations, their functions, and their safety requirements.

Refer to the Maintenance section and perform all the necessary inspection and maintenance steps.

Fuel Safety

Use extreme care when handling fuel.

Danger

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

A fire or explosion from gasoline 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 gasoline 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 gasoline to expand. Overfilling may result in fuel leakage or damage to the engine or emission system.

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

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

  • 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. Do Not use a nozzle lock open device.

Warning

Gasoline 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.

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.

Adding Fuel

Recommended 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.

Using Stabilizer/Conditioner

Use fuel stabilizer/conditioner in the machine at all times to keep the fuel fresh longer when used as directed by the fuel-stabilizer manufacturer.

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

Add the amount of fuel stabilizer/conditioner to fresh fuel as directed by the fuel-stabilizer manufacturer.

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 until the fuel gauge reads at the full mark (Figure 8).

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

Performing Daily Maintenance

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

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 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 blade-control switch (PTO) is disengaged.

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

  • The parking brake is engaged.

The safety-interlock system also is designed to shut off the engine whenever the control levers are out of the NEUTRAL-LOCK position and you rise from the seat.

    • 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 while ill, tired, or 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.

    • 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. Stop engine, wait for all moving parts to stop, and remove the spark plug wire(s).

      • 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.

      g229111
    • 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.

    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.

    Warning

    The machine can spin very rapidly. You may lose control of the machine and cause personal injury or damage to the machine.

    • Use caution when making turns.

    • Slow the machine down before making sharp turns.

    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 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

    The machine is equipped with a foot pedal deck-lift system. You 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. You can use the height-of-cut lever with the foot pedal to lock the deck in a specific cutting height.

    Using the Foot Pedal Deck-Lift System

    • Press the deck-lift pedal down to raise the deck; continue to press the pedal until the deck locks in the transport position (Figure 25).

    • Push on the deck-lift pedal with your foot and pull the transport lock handle rearward to disengage the transport lock (Figure 25).

    g024409

    Adjusting the Height of Cut

    You can adjust the height of cut from 38 to 114 mm (1-1/2 to 4-1/2 inches) in 6 mm (1/4 inch) increments by moving the height-of-cut pin into different hole locations.

    1. Push on the deck-lift pedal with your foot and raise the mower deck to the transport-lock position (also the 114 mm (4-1/2 inch) cutting height position) as shown in Figure 26.

    2. To adjust, remove the pin from the height-of-cut bracket (Figure 26).

    3. Select a hole in the height-of-cut system corresponding to the desired height of cut and insert the pin (Figure 26).

    4. Push on the deck-lift pedal with your foot and pull the handle rearward to disengage the transport lock (Figure 25).

    5. Lower the deck slowly until the lever makes contact with the pin.

      g188850

    Adjusting the Anti-Scalp Rollers

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

    Note: Adjust the anti-scalp rollers so that the rollers do not touch the ground in normal, flat mowing areas.

    1. Park the machine on a level surface, disengage the blade-control switch and engage the parking brake; refer to Engaging the Parking Brake.

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

    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, remove key or disconnect spark plug wire. 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.

    Transporting

    Transporting the Machine

    Use a heavy-duty trailer or truck to transport the machine. Ensure that the trailer or truck has all necessary lighting and marking as required by law. Thoroughly read all of the safety instructions. Knowing this information could help you, your family, pets, or bystanders avoid injury.

    To transport the machine:

    • Lock the brake and block the wheels.

    • Be sure the fuel shut-off valve is closed.

    • Securely fasten the machine to the trailer or truck with straps, chains, cable, or ropes. Only use the four designated tie-down locations on the mower–two on the left side and two on the right (Figure 28). Use these locations even when transporting the mower with an attached accessory. Using non-designated locations may cause damage to the mower and/or attachment.

      g027708
    • Secure a trailer to the towing vehicle with safety chains.

      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.

    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).

    g027995

    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 29). 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.

    • 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

    Towing the Machine

    • Do not attach towed equipment except at the hitch point.

    • Follow the attachment manufacturer's recommendation for weight limits for towed equipment and towing on slopes. Towed weight must not exceed the weight of the machine, operator, and ballast; otherwise hydrostatic transmission failure may occur. Use counterweights or wheel weights as described in the attachment manufacturer's manual.

    • Never allow children or others in or on towed equipment.

    • On slopes, the weight of the towed equipment may cause loss of traction, increased risk of rollover, and loss of control. Reduce the towed weight and slow down.

    • Stopping distance increases with the weight of the towed load. Travel slowly and allow extra distance to stop.

    • Make wide turns to keep the attachment clear of the machine.

    Pushing the Machine by Hand

    Important: Always push the machine by hand. Do not tow the machine, because towing may damage it.

    This machine has an electric-brake mechanism, and to push the machine, the key must be in the RUN position. The battery needs to be charged and functioning to disengage the electric brake.

    Mower 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, keep extra blades on hand.

    Before Inspecting or Servicing the Blades

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

    2. Shut off the engine, remove the key, and disconnect the spark-plug wires from the spark plugs.

    Inspecting the Blades

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Inspect the blades.
    1. Inspect the cutting edges (Figure 51).

    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 51).

      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 52).

      g014972
    3. Measure from the tip of the blade to the flat surface (Figure 53).

      g014973
    4. Rotate the same blade 180 degrees so that the opposing cutting edge is now in the same position (Figure 54).

      g014974
    5. Measure from the tip of the blade to the flat surface (Figure 55).

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

    2. Remove the blade bolt, curved washer, and blade from the spindle shaft (Figure 56).

      g010341

    Sharpening the Blades

    1. Use a file to sharpen the cutting edge at both ends of the blade (Figure 57).

      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 58).

      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 57).

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

    Installing the Blades

    1. Install the blade onto the spindle shaft (Figure 56).

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

    2. Install the curved washer (cupped side toward the blade) and the blade bolt (Figure 56).

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