This manual contains instructions and warnings that identify potential hazards and recommendations for reducing the risk of injury during use. This battery-powered stand-on mower is designed for mowing large residential or commercial lawns with dry, flat, and even terrain. It is not designed for any other purpose. It is important that you read and understand the manual thoroughly before attempting to start or operate this equipment.

The illustrations in this manual are meant to complement the text. The illustrations are representative, and your mower may have features or components that differ from those depicted in this manual.

As used in the manual, LEFT and RIGHT refer to the directions when viewed from the operator’s perspective standing on the platform.

Read all safety warnings, instructions, illustrations and specifications provided with this mower. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future reference.

To avoid bystander contact with the moving blade or a thrown object injury, keep the area of operation clear of all bystanders, particularly small children. Stop the lawnmower and any attachment(s) if anyone enters the area. Contact with the moving blade or thrown objects may result in serious personal injury or death.

Only operate the lawnmower in daylight or good artificial light. Dark areas invite accidents.

Do not operate lawnmowers in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Lawnmowers create sparks which may ignite the dust and fumes.

Do not use the lawnmower in bad weather conditions, especially when there is a risk of lightning. This decreases the risk of being struck by lightning.

Thoroughly inspect the area where the lawnmower is to be used and remove all stones, sticks, wires, bones, and other foreign objects. Thrown objects can cause personal injury.

Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

Do not expose the lawnmower to rain or wet conditions. Water entering a lawnmower may increase the risk of electric shock.

Do not clean the machine with water from a hose or a pressure washer. Water entering a machine will increase the risk of electric shock.

Use personal protective equipment. Always wear eye protection. Protective equipment will reduce personal injuries.

Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.

While operating the lawnmower, always wear long trousers. Exposed skin increases the likelihood of injury from thrown objects.

While operating the lawnmower, always wear non-slip and protective footwear. Do not operate the lawnmower when barefoot or wearing open sandals. This reduces the chance of injury to the feet from contact with the moving blades.

Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or batteries, picking up or carrying the lawnmower. Carrying a lawnmower with your finger on the switch or energizing a lawnmower that has the switch on invites accidents.

Remove any adjusting key or wrench before turning the lawnmower on. A wrench or a key left attached to a rotating part of the lawnmower may result in personal injury.

Keep proper footing and balance at all times. This enables better control of the lawnmower in unexpected situations.

Stay alert, watch what you are doing and use common sense when operating a lawnmower. Do not use a lawnmower while you are tired, ill or under the influence of drugs, alcohol or medication. If signs of fatigue occur, take a break. A moment of inattention while operating a lawnmower may result in serious personal injury.

Do not let familiarity gained from frequent use of lawnmower allow you to become complacent and ignore lawnmower safety principles. A careless action can cause severe injury within a fraction of a second.

To avoid operator blade contact or a thrown object injury, stay in the operator zone behind the lawnmower handles. Blade contact or thrown objects may result in serious personal injury.

Do not touch blades and other hazardous moving parts while they are still in motion. This reduces the risk of injury from moving parts.

Use the lawnmower and accessories in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the lawnmower for operations different from those intended may result in a hazardous situation.

Before using the lawnmower, always visually inspect to see that the blade(s) and the blade(s) assembly are properly secured and not worn or damaged. Loose, worn, or damaged parts may increase the risk of injury.

Keep guards and other safety devices in place, properly mounted, and in working order. A guard or other safety device that is loose, damaged, or is not functioning correctly may result in personal injury.

Keep all cooling air inlets clear of debris. Blocked air inlets and debris may result in overheating or risk of fire.

Do not use the lawnmower if the switch does not turn it on and off. Any lawnmower that cannot be controlled with the switch is dangerous and must be repaired.

Do not operate the lawnmower in wet grass. Walk, never run. This reduces the risk of slipping and falling which may result in personal injury.

Do not operate the lawnmower on excessively steep slopes. This reduces the risk of loss of control, slipping and falling which may result in personal injury.

Do not force the lawnmower. Use the correct lawnmower for your application. The correct lawnmower will do the job better and safer at the rate for which it was designed.

Be aware of the mower and attachment discharge direction and do not point the mower discharge at anyone. Thrown objects can cause personal injury.

Use extreme caution when reversing or pulling the lawnmower towards you. Always be aware of your surroundings. This reduces the risk of tripping during operation.

When working on slopes, always be sure of your footing, always work across the face of slopes, never up or down and exercise extreme caution when changing direction. This reduces the risk of loss of control, slipping and falling which may result in personal injury.

Operate the disabling device and/or remove all battery packs, if removable, from the lawnmower before making any adjustments, changing accessories, or storing the lawnmower. Such preventive safety measures reduce the risk of starting the lawnmower accidentally.

Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the lawnmower in unexpected situations.

Before unclogging the chute, turn off the motor, wait until the blade(s) comes to a complete stop, operate the disabling device and/or remove all batteries, if removable. The cutting blade(s) continues to rotate after the blade control is released. Never place any part of the body in the blade(s) area until you are certain the motor is off and the blade(s) has stopped rotating. Contact with the moving cutting blade(s) may result in serious personal injury.

Before cleaning or inspecting the lawnmower, turn off the motor, wait until the blade(s) comes to a complete stop, operate the disabling device and/ or remove all batteries, if removable. Accidental contact with the moving blade and moving parts may result in personal injury.

Maintain the lawnmower and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the lawnmower’s operation. If damaged, have the lawnmower repaired before use. Many accidents are caused by poorly maintained lawnmowers.

Store idle lawnmowers out of the reach of children and do not allow persons unfamiliar with the lawnmower or these instructions to operate the lawnmower. Lawnmowers are dangerous in the hands of untrained users.

Disconnect the machine from the power source and/or remove the battery, if detachable, from the mower before making any repairs or changing blades, or storing mowers. Such preventive safety measures reduce the risk of starting the mower accidentally.

Remove the key or disable the machine when leaving the machine unattended. Machines are dangerous to untrained users.

Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery may create a risk of fire when used with another battery.

Use mowers only with specifically designated battery. Use of any other battery may create a risk of injury and fire.

When battery is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.

Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water.

Do not use a battery or mower that is damaged or modified. A damaged or modified battery may exhibit unpredictable behavior resulting in fire, explosion or risk of injury.

Do not expose a battery or mower to fire or excessive temperature. Exposure to fire or temperature above +131° F (+55° C) may cause explosion.

Follow all charging instructions and do not charge the battery or mower outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

Have your mower serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the mower is maintained. Use of parts which do not meet the original equipment specifications may lead to improper performance and compromise safety.

Never service damaged battery. Service of battery should only be performed by the manufacturer or authorized service providers.

Always keep both hands on the motion control handles during operation. Do not operate with one hand.

Read and understand the Instruction Manual BEFORE starting work. It contains important safety information that will help you reduce the risk of injury DURING operation.

Read this Instruction Manual thoroughly before use and follow all safety precautions. Improper use can cause serious or fatal injury.

Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the mower 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 other than the operator. If children enter the mowing area, shut off the mower.

Do not carry children, even with the blade(s) off. They may fall off and be seriously injured or interfere with safe operation. Children who have been given rides in the past may suddenly appear in the mowing area for another ride and be run over or backed over by the mower.

Before changing direction (including backing) always look down and behind you for small children.

Use caution when mowing around obstacles such as bushes that obscure vision.

Clear the operating area of any objects that could be thrown by or interfere with the operation of the mower.

Do not carry passengers anywhere on the mower. Keep pets and bystanders out of the mowing area during operation.

Keep the mowing area clear of all bystanders, particularly small children. Stop the machine and attachments if anyone enters the area.

Do not operate mower without the entire discharge chute or other safety devices in place and functioning properly. Check frequently for signs of wear or deterioration and replace as needed.

Wear appropriate personal protective equipment such as safety glasses, hearing protection, and footwear.

LED lights on the mower are not suitable for night time mowing. Only operate in daylight or good artificial light.

Avoid holes, ruts, bumps, rocks or other hidden hazards. Uneven terrain could overturn the mower or cause the operator to lose balance or footing.

This mower is not designed for operation on public roads. Avoid operation on public roadways.

Operating the mower without all safety equipment in place increases the risk of injury. Be sure all guards are properly installed and secure. Ensure that all interlocks and safety switches are properly adjusted and functioning as designed.

Never leave an activated machine unattended. Take appropriate precautions when stopping the mower or leaving the operator’s position. Always stop on level ground. Disengage the PTO, set the parking brake, switch off the power and remove the key before stepping off the platform. This includes removing debris from the mowing area or unblocking the discharge chute.

Never direct discharge material toward anyone. Avoid discharging material against a wall or obstruction. Material may ricochet back toward the operator. Stop the blade(s) when crossing gravel surfaces.

Use caution when approaching blind corners, including vegetation or other objects that may limit the operator’s vision.

Do not mow in reverse unless absolutely necessary. Always look down, behind and to the side before changing directions or backing up.

Slow down on slopes and use caution any time you are changing direction on slopes.

Disengage the PTO and ensure the mowing blades are stopped before raising the deck.

Disengage the mowing blades by turning off the PTO switch any time you are not mowing.

Inspect mowing blades in the event you strike an object or experience abnormal vibration during operation.

Never operate on a slope greater than 15 degrees – a slope that has 5 feet of elevation change over any 20 foot segment.

Reduce speed and use extra care when mowing on slopes. If you cannot back up the slope or if you feel uncomfortable, do not drive on the slope.

Avoid turning the mower down slopes. Turn up slopes.

Always keep the machine in gear when going down slopes. Do not coast downhill.

Avoid starting and stopping on slopes. Avoid making sudden changes in speed or direction. Make turns slowly and gradually.

Avoid mowing grass that is slippery, wet, or soft. Operating on wet or soft slopes can cause loss of control, which can lead to tip over.

Use extra care while operating the mower with accessories and other attachments. They can affect the stability of the machine.

To check the degree of slope on your lawn, you can:

Download an inclinometer app onto your mobile device that measures slopes.

Place a flat piece of wood or metal, 4-6 feet in length, on the surface of the slope.

Open the app and place your phone on the flat piece of metal or wood to determine the exact slope of your lawn. Do not mow if the slope is greater than 15 degrees.

Drop-offs around steps and water are a common hazard. Never operate your mower down a slope towards water, a retaining wall, or other drop-off. Use extra caution when operating the mower in the vicinity of such hazards.

To reduce the risk of falling into water, down steps, or over the edge of a drop-off, always leave yourself 2 mower widths of clearance between your mower and the hazard. Failure to maintain sufficient clearance may result in serious injury, death, or drowning.

This unit produces sound levels in excess of 85 dBA at the operator’s ear and can cause hearing loss through extended periods of exposure. Always wear hearing protection when operating this mower.

The mower is equipped with a safety start interlock system consisting of the parking brake, operator presence control sensor, and PTO switch, key and contact breaker switch.

The operator presence control sensor includes platform sensor and motion control handles. It can be activated when either of the motion control handles is not in the parking brake position and switch between stand on mode and walk behind mode when the platform is in down position.

The mower’s interlock system is also designed to protect the operator and others from injury due to unintentional drive activation.

Check mower safety start interlock system daily prior to operation. This system is an important mower safety feature. It should be repaired immediately if it malfunctions.

Prior to operating the stand-on mower, ensure you have studied the FEATURES AND CONTROLS section to grasp control functions. Using the motion control handles to master smooth and efficient control over forward, reverse, and turning requires practice. Familiarize yourself with acceleration, travel, and steering by practicing maneuvers in a clear, open lawn area, free of obstacles and hazards. Drive at low speeds to prevent tire slippage and lawn damage. Start with the Smooth Travel procedure and progress through forward, reverse, and turning maneuvers.

The stand-on mower’s motion control handles are quick to respond. The optimal approach for managing these handles involves three steps:

1. Place your hands onto the handles.

2. To move forward slowly, push the handles forward with your palms.

3. To reach the maximum of the set speed, move the handles farther forward. For a gentle deceleration, move the handles towards neutral.

Move both motion control handles evenly and gradually forward from neutral. Practice slowing down and repeating.

Mastering straight forward travel requires practice. Adjust the speed as needed; refer to the speed adjustment in the LED DISPLAY section of this manual.

Look behind and down, then gradually pull both motion control handles evenly back from neutral. Practice slowing down and repeating.

Spend several minutes practicing reverse before doing so near objects. Remember, the stand-on mower turns sharply in reverse, similar to forward motion, and backing up straight requires practice.

While moving forward, gently bring one motion control handle back towards neutral. Practice this repeatedly.

To reduce potential damage to the lawn, avoid pivoting directly on the tire tread by ensuring both wheels maintain a slight forward motion.

For a “zero-turn” maneuver, gradually move one motion control handle forward from neutral while moving the other handle back from neutral simultaneously. Practice this several times.

Adjusting the extent of pulling each motion control handle forward or back alters the turning “pivot point.”

Your stand-on mower’s exceptional feature of turning in place allows you to pivot at the row’s end instead of stopping and performing a Y-turn before commencing a new row.

Here’s how to execute a left end-of-row zero turn:

1. Gradually decelerate at the row’s end.

2. Slightly push the RIGHT motion control handle forward while moving the LEFT motion control handle back to its center and then slightly back.

3. Resume forward mowing.

By adopting this approach, the mower turns left and slightly overlaps the recently cut row, eliminating the necessity to backtrack and re-cut any missed grass.

Select a smooth, level area to mow. Be cautious of trees, fences, and slopes. Mow in straight lines, slightly overlapping. Occasionally change patterns to prevent flat spots.

For a professional touch, mow across once and then go perpendicular on the next round.

When mowing expansive spaces, begin by turning towards the right to ensure that clippings are directed away from shrubs, fences, driveways, and other areas. After completing one or two rounds, mow in a back-and-forth pattern across the lawn, pivoting at the edges of the previously mowed grass.

Broadcasting also known as side discharge, is a mowing technique that efficiently processes a larger volume of grass in a single pass. This method involves expelling grass clippings to the side of the mower deck and dispersing them across the lawn. The side discharge deck design allows for effective cutting even in high grass conditions, making it ideal for larger areas where expedited mowing is essential. For optimal mowing, set blade speed to the highest level. If the motor slows, reduce drive speed. Slower drive speed boosts blade efficiency and prevents cutting issues. Choose broadcast mowing for 3-5 inch grass. Avoid cutting more than 1 inch at once.

Mulching offers versatile benefits, finely cutting grass and returning clippings to the soil. Remember, mulching works best on dry and moderate-height grass. For successful mulching, set the blade speed highest and match it with the slowest driving speed. This ensures finely cut clippings. When mulching, drive at about half the speed used for broadcasting.

Ideal mulching trims just the top ½ – ¾ inch of grass, resulting in decomposing clippings. Experiment with cutting height based on your climate, season, and lawn thickness.

As always, mow thoughtfully and consider your lawn’s unique conditions for the best results.

Cutting height often depends on preference. Typically, mow when grass is 3-5 inches high. Proper height varies based on grass type, rainfall, temperature, and lawn health. Cutting too short weakens grass and makes it prone to damage by dry periods and pests. Slightly longer grass is less prone to damage. Longer growth in hot, dry conditions reduces heat stress, conserves moisture, and guards against damage. Keeping the grass too long leads to thin turf and problems. Don’t cut too much at once; follow the 1/3 rule: trim a maximum of 1/3 and no more than 1 inch at a time.

Mowing capacity depends on your chosen mowing system. Broadcasting with side discharge decks handles more grass than mulching.

Tall grass needs gradual cutting. For very tall grass, begin with max height (A), then lower it for the second (B) or third pass. Avoid leaving excessive clippings on top of the grass. Consider a grass collection system or composting. Remember, different systems are suited to different situations.

The timing and grass condition significantly influence mowing outcomes. Follow these guidelines for best results:

Mow when grass height is between 3 to 5 inches.

Use sharp blades for precision. Short clippings under one inch decompose faster, and sharp blades prevent frayed edges.

Choose a cool and dry time of day for mowing, like late afternoon or early evening.

Avoid mowing after rain or heavy dew. Never mulch wet grass as it clumps beneath the mower deck and doesn’t mulch effectively.

Do not tow this mower, it may cause damage to the drive system.

Do not load mower on a trailer or truck using two separate ramps. Only use a single width ramp that is at least one foot wider than the width of the rear wheels of the mower. The rear wheels could fall off the ramps or the unit could tip over injuring the operator or bystanders. Ensure the cutting deck is raised to the highest position so it does not get caught on the ramp.

Park the mower on a level surface.

Raise the cutting deck to the highest position.

Position and secure ramp to the trailer according to manufacturer’s instructions.

Use a full width loading ramp that is at least 1 ft. wider than the mower to reduce the risk of driving off the side of the ramp.

Back the machine up the ramp and walk it forward down the ramp.

Avoid sudden acceleration or deceleration while driving on a ramp as it may result in loss of control or a potential tip-over.

After loading, lower mower deck completely.

Pivot the motion control handles outward to engage the parking brake.

Turn off mower and remove key.

Secure the mower as needed using straps or cables to prevent movement during transport. The tie down points are shown in the figure (two points at each side).

To avoid accidental starting or movement that could result in serious personal injury, always remove the key and engage the parking brake when transporting the mower.

To push the mower manually:

1. Disengage the blades and push the motion control handles outward to engage the parking brake.

2. Press the activation button to turn the mower OFF. Remove the key, and wait for all moving parts to stop before leaving the operating position.

3. Unlock the transmission release levers to release the parking brakes.

4. Move the mower to the desired location.

To avoid damage to the motor and drive mechanism, do not move the machine faster than 5 mph (8 km/h) or it may cause damage to the mower.

5. Immediately after moving the mower, lock the transmission release levers.

The transmission release levers disengage the drive system that connects the engine power to the wheels and may be used when you need to manually push or move the mower without the engine running.

1. Locate the transmission release levers situated underneath the rear of the mower’s frame. These levers individually manage the drive wheels.

2. Unlock the levers to release the drive brakes.

3. Lock the levers for regular operation.

The mower does not have brakes when the transmission is disengaged. It can roll uncontrolled, possibly causing injury. Never unlock the transmission release levers when the mower is on a slope. Once the levers are released, the mower can roll freely and does not have a brake. Releasing the lever on a slope could lead to loss of control and increase the risk of serious personal injury.

Remove any build-up of grass and leaves on or around the motor cover (Do not use water).

Occasionally wipe the mower clean with a dry cloth.

If debris builds up on the underside of the mower during use, stop the mower on level ground, disengage the PTO, set the parking brake, shut off the mower, remove the key and use compressed air to clean the area.

To ensure proper storage of the mower, follow these steps:

Cleaning the Mower: Before storing the machine, thoroughly clean it as outlined in the previous section.

Blade Inspection and Maintenance: Inspect the blades and either replace or sharpen them as detailed in the SERVICING THE MOWER BLADES section.

Avoid Corrosive Materials: Keep the mower away from corrosive substances, such as fertilizer or rock salt, as these can lead to rust and corrosion on metal components like the blade, deck, motor, and frame. Keep the mower and its battery away from conductive or corrosive materials to reduce the risk of short circuit, fire, explosion and other electrical hazards.

Child Safety: Store the machine in a location inaccessible to children to prevent accidents.

Proper Covering: Do not cover the machine with a solid plastic sheet. Plastic coverings can trap moisture, which promotes rust and corrosion.

Use of parts which do not meet the original equipment specifications may lead to improper performance and compromise safety.

The mower is powered by a battery which, when maintained properly, will provide years of useful life. For proper care, adhere to the following instructions:

Always charge battery after each use. Over-discharge will shorten battery life and risk permanent damage. If a full charging cycle is not possible immediately after cutting, a 5-10 minute cycle will help maintain battery health. Fully re-charge the battery within 24 hours after use. To maintain proper calibration, run and charge the mower at least once a month. Complete a full charge every six months. Keep grass, dirt and debris from collecting in battery area. Charge battery in an enclosed, dry area away from sparks and flames. Never expose charger to rain, water vapor or other liquids. Do not touch uninsulated portion of charger (terminal pins) or output connector. Do not use charger if cords are damaged.

Routine maintenance should include cleaning and inspection.

1. During the battery charging process:

Make sure the charging plug connects securely and fully in the socket;

Make sure the charger operates without faults;

Address any faults and have them repaired before charging.

2. During the operation of the mower and when charging the battery, keep the charging port away from water and other conductive materials. Never charge when the mower is wet.

3. Charging time will depend on a number of factors, including battery health, ambient temperatures and other factors. Monitor the battery for abnormal performance or behavior.

The battery charging port is located on the left back housing of the mower. Open the charging flap, and press the release button (A) to open the port cover (B) to charge. Close the charging flap and the cover once the charging is finished to reduce the risk of electric shock.

To reduce the risk of fire and explosion, keep open flames and sparks away from the mower and its battery. Ensure proper ventilation around the mower while charging.

To charge the battery, follow the instructions provided by the BATTERY AND CHARGER section as well as all warnings included in the OPERATOR SAFETY section of this manual. Charge the battery until fully charged.

Open the charging flap and the port cover (B) from the battery charging port on the mower.

Plug the charger into the DC battery charging port (B).

Plug the charger into a AC power outlet.

When the mower is charging, the digital display will show the charging screen only. It will display the battery percentage.

Unplug the charger from the AC power outlet.

Unplug the charger from the battery charging port.

Do not exceed maximum charging time: 25 hours.

Cover the battery charging port with the charging flap and the port cover before mowing to prevent foreign objects from entering and causing damage to the port.

Tire pressure should be checked periodically, and maintained at the levels shown below. Notice that these recommendations may differ slightly from the “Max Inflation” stamped on the side-wall of the tires. Exceeding the max inflation will lead to a tire explosion. The pressures shown provide proper traction and extend tire life.

Particular attention must be given to tightening the drive wheel lug nuts and blade spindle bolts. Failure to correctly torque these items may result in the loss of a wheel or blade, which can cause serious damage or personal injury.

Torque values are given below:

Check lug nuts after the first 2 hours of operation, then every 100 operating hours and following removal for repair or replacement.

1. Use a general purpose lithium-based grease 3# to lubricate the grease fittings (A) (B) on both front casters and the front wheel hubs. Grease the front wheel hubs and the front casters every 25 operating hours.

2. Use a general purpose lithium-based grease 3# to lubricate the oot platform pivots as shown below every 25 operating hours. Increase lubrication frequency in hot weather (above 85 ℉ , 30℃ ) or dusty operating conditions.

Mower blades are sharp. Always wear gloves when handling or working near mower blades.

1. Park the mower on a flat level surface, disengage the PTO and pivot the motion control handles outward to engage the parking brake. Shut off the mower, remove the key and disconnect the contact breaker switch.

2. Use a jack stand to lift the front of the mower chassis upward for easier access to the blades. A jack stand with a minimum 550 lbs jack lift capacity is recommended. The jack stand can be put against the front hitch. Ensure the mower is secure before working underneath it.

3. Place a block of wood between the blade and the deck to prevent it from spinning while you work. Use a 24 mm socket wrench to loosen and remove the blade bolt, spacer, blade, and blade support.

Make sure the mower is secured when it is lifted by the jack stand and while working on it.

A worn or damaged mower blade has the potential to break, leading to fragments being propelled into the operator’s or bystander’s area, causing severe personal harm or death. Inspect every 25 hours. Halt operation if the mower hits an object and inspect for damage.

Mower blades are sharp. Always wear gloves when handling or working near mower blades.

Inspection:

Remove the mower blade from the mower.

Inspect the mower blades to assess whether they are blunt and require sharpening or display signs of damage and should be replaced. Blades showing cracks, corrosion, rust, excessive wear or bending should be discarded.

Using a grinder or electric sharpener for mower blade sharpening generates sparks and metal particles that can ignite gasoline and vapors. Clear flammable materials from the area and wear safety glasses or goggles.

Sharpening:

If the cutting edges are simply not sharp enough or have nicks, proceed to sharpen.

Secure the blade in a vice. Then use a grinder, hand file, or electric blade sharpener to sharpen the mower blades by removing an equal amount of material from the cutting edge from each end.

Keep the original bevel (A) when grinding. Do NOT change the mower blade bevel.

The mower blade should have a maximum cutting edge (B) of 1/64″ (0.40 mm) or less.

An unbalanced blade can cause vibrations, mower damage, or blade failure which may result in thrown debris. Ensure blade is balanced before installing.

Balancing:

Secure a nail in a vise, hang the blade on it, and level it.

Assess blade balance. If an end drops, it’s heavier; sharpen it until balance is reached.

Repeat until the blade stays horizontal and level.

Mower blades are sharp. Always wear gloves when handling or working near mower blades.

1. Install the new blades following the specified sequence: blade support, blade, spacer, and blade bolt. Ensure that the cutting edge of the blade is oriented toward the deck in the indicated order.

Incorrect orientation of the blades can damage the cutting deck and impact the mower’s stability which can affect operator’s safety.

2. Securely tighten the blade bolts by rotating clockwise with a 24 mm socket or wrench. Torque to 118 Ft-lbs (160 Nm).

The cutting height range is 1″ ~ 5″.
