SAFETY
Rotating Blades are Dangerous
HELP PREVENT SERIOUS OR FATAL ACCIDENTS:
Rotating blades can cut off arms and legs, and throw objects. Failure to observe safety instructions could result in serious injury or
death.
Keep hands, feet and clothing away from mower deck when engine is running.
Be alert at all times, drive forward and in reverse carefully. People, especially children can move quickly into the mowing area before you know it.
Before backing up, stop mower blades or attachments and look down and behind the machine carefully, especially for children.
Do not mow in reverse.
Shut off blades when you are not mowing.
Park machine safely before leaving the operators station for any reason including emptying the grasscatchers or unplugging the chute.
The mower blades should stop in approximately five seconds when the mower is disengaged. If you believe that your blades may not be stopping in that period of time, take your machine to your authorized dealer where they can safely check and service your machine.
Protect Children
Death or serious injury can occur when young children associate having fun with a lawn mowing machine simply because someone has given them a ride on a machine.
Children are attracted to lawn mowing machines and mowing activities. They dont understand the dangers of rotating blades or the fact that the operator is unaware of their presence.
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 machine.
Tragic accidents with children can occur if the operator is not alert to the presence of children, especially when a child approaches a machine from behind. Before and while backing up, stop mower blades and look down and behind the machine carefully, especially for children.
Never carry children on a machine or attachment, even with the blades off. Do not tow children in a cart or trailer. They can fall off and be seriously injured or interfere with safe machine operation.
Never use the machine as a recreational vehicle or to entertain children.
Never allow children or an untrained person operate the machine. Instruct all operators not to give children a ride on the machine or in an attachment.
Keep children indoors, out of the mowing area, and in the watchful eye of a responsible adult, other than the operator, when a mower is being operated.
Stay alert to the presence of children. Never assume that children will remain where you last saw them. Turn the machine off if a child enters the work area.
Use extreme care when approaching blind corners, shrubs, trees, or other objects that may block your view of a child.
Avoid Tipping
Slopes are a major factor related to loss-of- control and tip-over accidents, which can result in severe injury or death. Operation on all slopes requires extra caution. If you cannot back up the slope or if you feel uneasy on it, do not mow it.
Mow up and down slopes, not across.
Watch for holes, ruts, bumps, rocks, or other hidden objects. Uneven terrain could overturn the machine. Tall grass can hide obstacles.
Choose a low ground speed so you will not have to stop or shift while on a slope.
Do not mow or operate machine on wet grass. Tires may lose traction. Tires may lose traction on slopes even though the brakes are functioning properly.
Always keep the machine in gear when going down slopes. Do not shift to neutral and coast downhill.
Avoid starting, stopping or turning on a slope. If the tires lose traction, disengage the blades and proceed slowly, straight down the slope.
Keep all movement on slopes slow and gradual. Do not make sudden changes in speed or direction, which could cause the machine to roll over.
Use extra care while operating machine with grasscatchers or other attachments, they can affect stability of the machine. Do not use on steep slopes.
Do not try to stabilize the machine by putting your foot on the ground.
Do not mow near drop-offs, ditches, embankments, or bodies of water. The machine could suddenly roll over if a wheel goes over the edge or the edge caves in.
Follow the manufacturers recommendations for wheel weights or counterweights for added stability when operating on slopes or using front or rear mounted attachments. Remove weights when not required.
Keep Riders Off
Only allow the operator on the machine. Keep riders off.
Riders on the machine or attachment may be struck by foreign objects or thrown off the machine causing serious injury.
Riders obstruct the operators view resulting in the machine being operated in an unsafe manner.
Towing Loads Safely
Stopping distance increases with speed and weight of towed load. Travel slowly and allow extra time and distance to stop.
Total towed weight must not exceed combined weight of pulling machine, ballast and operator. Use counterweights or wheel weights as described in the attachment or pulling machine operators manual.
Excessive towed load can cause loss of traction and loss of control on slopes. Reduce towed weight when operating on slopes.
Never allow children or others in or on towed equipment.
Use only approved hitches. Tow only with a machine that has a hitch designed for towing. Do not attach towed equipment except at the approved hitch point.
Follow the manufacturers recommendations for weight limits for towed equipment and towing on slopes.
If you cannot back up a slope with a towed load, the slope is too steep to
Safety - 5
SAFETY
Do not turn sharply. Use additional caution when turning or operating under adverse surface conditions. Use care when reversing.
Do not shift to neutral and coast downhill.
Wear Appropriate Clothing
Always wear eye protection when operating the machine.
Wear close fitting clothing and safety equipment appropriate for the job.
While mowing, always wear substantial footwear and long trousers. Do not operate the equipment when barefoot or wearing open sandals.
Wear a suitable protective device such as earplugs. Loud noise can cause impairment or loss of hearing.
Driving Safely on Public Roads Avoid personal injury or death resulting from a collision with another vehicle on public roads:
Use safety lights and devices. Slow moving machines when driven on public roads are hard to see, especially at night.
Whenever driving on public roads, use flashing warning lights and turn signals according to local regulations. Extra flashing warning lights may need to be installed.
Practice Safe Maintenance
Only qualified, trained adults should service this machine. Understand service procedure before doing work.
Never operate machine in a closed area where dangerous carbon monoxide fumes can collect.
Keep all nuts and bolts tight, especially blade attachment bolts, to be sure the equipment is in safe working condition.
Never tamper with safety devices. Check their proper operation regularly.
Keep machine free of grass, leaves or other debris build-up. Clean up oil or fuel spillage and remove any fuel-soaked debris. Allow the machine to cool before storing.
If you strike a foreign object, stop and inspect the machine. Repair, if necessary, before restarting.
Never make any adjustments or repairs with the engine running. Wait for all movement to stop on machine before adjusting, cleaning or repairing.
Check grasscatcher components and the discharge guard frequently and replace with manufacturers recommended parts, when necessary. Grasscatcher components are subject to wear, damage, and deterioration which could expose moving parts or allow objects to be thrown.
Mower blades are sharp. Wrap the blade or wear gloves, and use extra care when servicing them. Only replace blades. Never straighten or weld them.
Check brake operation frequently. Adjust and service as required.
Maintain or replace safety and instruction labels, as necessary.
On multi-bladed machines, take care as rotating one blade can cause other blades to rotate.
Keep hands, feet, clothing, jewelry, and long hair away from any moving parts, to prevent them from getting caught.
Lower any attachments to the ground before cleaning or servicing machine. Disengage all power and stop the engine. Lock park brake and remove the key. Let machine cool.
Securely support any machine elements that must be raised for service work. Use jack stands or lock service latches to support components when needed.
Disconnect battery or remove spark plug wire (for gasoline engines) before making any repairs. Disconnect negative terminal first and positive last. Install positive terminal first and negative last.
Before servicing machine or attachment, carefully release pressure from any components with stored energy, such as hydraulic components or springs.
Release hydraulic pressure by lowering attachment or cutting units to the ground or to a mechanical stop and move hydraulic control levers back and forth.
Keep all parts in good condition and properly installed. Fix damage immediately. Replace worn or broken parts.
Charge batteries in an open, well-ventilated area, away from sparks. Unplug battery charger before connecting or disconnecting from the battery. Wear protective clothing and use insulated tools.
Do not strike the flywheel with a hammer or hard object because the flywheel may later shatter during operation.
Avoid High Pressure Fluids
Hydraulic hoses and lines can fail due to physical damage, kinks, age, and exposure. Check hoses and lines regularly. Replace damaged hoses and lines.
Hydraulic fluid connections can loosen due to physical damage and vibration. Check connections regularly. Tighten loose connections.
Escaping fluid under pressure can penetrate the skin causing serious injury. Avoid the hazard by relieving pressure before disconnecting hydraulic or other lines. Tighten all connections before applying pressure.
Search for leaks with a piece of cardboard. Protect hands and body from high pressure fluids.
If an accident occurs, see a doctor immediately. Any fluid injected into the skin must be surgically removed within a few hours or gangrene may result. Doctors unfamiliar with this type of injury should reference a knowledgeable medical source. Such information is available from Deere & Company Medical Department in Moline, Illinois, U.S.A. Information may be obtained in the United States and Canada only by calling 1-800-822- 8262.
Prevent Fires
Remove grass and debris from engine compartment and muffler area, before and after operating machine, especially after mowing or mulching in dry conditions.
Empty the grasscatcher completely before storing.
Always shut off fuel when storing or transporting machine, if the machine has a fuel shutoff.
Do not store machine near an open flame or source of ignition, such as a water heater or furnace.
Check fuel lines, tank, cap, and fittings frequently for cracks or leaks. Replace if necessary.
Safety - 6
ASSEMBLY
Handling Fuel Safely
To avoid personal injury or property damage, use extreme care in handling fuel. Fuel is extremely flammable and fuel vapors are explosive:
Extinguish all cigarettes, cigars, pipes, and other sources of ignition.
Use only an approved fuel container. Use only non-metal, portable fuel containers approved by the Underwriters Laboratory (U.L.) or the American Society for Testing & Materials (ASTM). If using a funnel, make sure it is plastic and has no screen or filter.
Never remove the fuel tank cap or add fuel with the engine running. Allow engine to cool before refueling.
Never add fuel to or drain fuel from the machine indoors. Move machine outdoors and provide adequate ventilation.
Clean up spilled fuel immediately. If fuel is spilled on clothing, change clothing immediately. If fuel is spilled near machine, do not attempt to start the engine but move the machine away from the area of spillage. Avoid creating any source of ignition until fuel vapors have dissipated.
Never store the machine or fuel container where there is an open flame, spark, or pilot light such as on a water heater or other appliance.
Prevent fire and explosion caused by static electric discharge. Static electric discharge can ignite fuel vapors in an ungrounded fuel container.
Never fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers on the ground away from your vehicle before fueling.
Remove fuel-powered equipment from the truck or trailer and refuel it on the ground. If this is not possible, then refuel such equipment with a portable container, rather than from a fuel dispenser nozzle.
Keep the nozzle in contact with the rim of the fuel tank or container opening at all times until the fueling is complete. Do not use a nozzle lock- open device.
Never overfill fuel tank. Replace fuel tank cap and tighten securely.
Replace all fuel container caps securely after use.
For gasoline engines, do not use gas with methanol. Methanol is harmful to your health and to the environment.
Tire Safety Explosive separation of a tire and rim parts can cause serious injury or death:
Do not attempt to mount a tire without the proper equipment and experience to perform the job.
Always maintain the correct tire pressure. Do not inflate the tires above the recommended pressure. Never weld or heat a wheel and tire assembly. The heat can cause an increase in air pressure resulting in a tire explosion. Welding can structurally weaken or deform the wheel.
When inflating tires, use a clip-on chuck and extension hose long enough to allow you to stand to one side and NOT in front of or over the tire assembly.
Check tires for low pressure, cuts, bubbles, damaged rims or missing lug bolts and nuts.
Checking Wheel Hardware
A serious accident could occur causing serious injury if wheel hardware
is not tight.
Check wheel hardware tightness often during the first 100 hours of operation.
Wheel hardware must be tightened to specified torque using the proper procedure anytime it is loosened.
Handling Waste Product and Chemicals Waste products, such as, used oil, fuel, coolant, brake fluid, and batteries, can harm the environment and people:
Do not use beverage containers for waste fluids - someone may drink from them.
See your local Recycling Center or authorized dealer to learn how to recycle or get rid of waste products.
A Material Safety Data Sheet (MSDS) provides specific details on chemical products: physical and health hazards, safety procedures, and emergency response techniques. The seller of the chemical products used with your machine is responsible for providing the MSDS for that product.
