Rotating Blades are Dangerous - Protect Children and Prevent Accidents


MIF

PROTECT CHILDREN:

ˇ Never assume that children will remain where you last saw them. Children are attracted to mowing activity, stay alert to the presence of children.

ˇ Keep children in the house when you are operating the machine.

ˇ Turn machine off if a child enters the mowing area.

ˇ Use extra care when you come to blind corners, shrubs, trees, or other objects that may block your vision.

ˇ DO NOT let children or an untrained person operate the machine.

ˇ DO NOT carry or let children ride on machine or any attachment. DO NOT tow children in a cart or trailer.

HELP PREVENT SERIOUS OR FATAL ACCIDENTS:

ˇ Be alert at all times, drive forward carefully. People especially children can move quickly into the mowing area before you know it.

ˇ Back carefully. Shut off PTO and look behind the machine carefully, especially for children, before you back up.

ˇ DO NOT mow in reverse unless it is absolutely necessary.

ˇ Shut off PTO when you are not mowing.

ˇ DO NOT operate machine if you are under the influence of drugs or alcohol.

Wear Appropriate Clothing


MIF

ˇ Wear close fitting clothing and safety equipment appropriate for the job.

ˇ Loud noise can cause impairment or loss of hearing, wear a suitable protective device such as earplugs.

ˇ Do not wear radio or music headphones while operating the machine. Safe operation requires your full attention.

Operator Training Required

ˇ Study operation section of this manual before operating the machine.

ˇ Operate machine in an open, unobstructed area under the direction of an experienced operator.

ˇ Learn the use of all controls.

ˇ Operator experience is required to learn the moving, stopping, turning and other operating characteristics of the machine.

Avoid Tipping

ˇ DO NOT operate machine without the mower deck installed.

ˇ DO NOT drive where machine could slip or tip.


MIF

ˇ Stay alert for holes and other hidden hazards in the terrain.

ˇ Keep away from drop-offs.

ˇ Slow down before you make a sharp turn or operate on a slope.

ˇ MOW ACROSS A HILL-NOT UP AND DOWN. Be careful when you change direction on a slope.

ˇ DO NOT stop when going up or down a hill. If machine stops going up hill, STOP PTO and back down slowly.

ˇ DO NOT mow wet grass. Reduced traction could cause sliding.

Operate Mower Safely on Slopes

Slopes are a major factor related to loss-of-control and tip-over accidents, which can result in severe injury or death. All slopes require extra caution. If an operator is uneasy mowing on a specific slope, DO NOT mow it.

ˇ MOW ACROSS SLOPES-NOT UP AND DOWN.

ˇ Remove obstacles such as rocks, tree limbs, etc.

ˇ Watch for holes, ruts, or bumps. Uneven terrain could overturn this machine. Tall grass can hide obstacles.

ˇ Keep all movement on slopes slow and gradual. DO NOT make sudden changes in speed or direction.

ˇ Avoid starting or stopping on a slope. If tires lose traction, disengage the mower blades and back slowly and gradually down the slope.

ˇ DO NOT turn on slopes unless necessary, and then, turn slowly and gradually downhill, if possible.

ˇ DO NOT mow near drop-offs, ditches, or embankments. The mower could suddenly turn over if a wheel is over the edge of a ditch, or if an edge caves in.

ˇ DO NOT mow on wet grass. Reduced traction could cause sliding.

ˇ DO NOT try to stabilize this machine by putting your foot on the ground.

Keep Riders Off


MIF

ˇ Only allow the operator on the machine. Keep riders off the machine.

ˇ Riders on the machine may be struck by foreign objects or thrown off the machine causing serious injury.

ˇ Riders obstruct the operator's view resulting in the machine being operated in an unsafe manner.

Transport Safely

ˇ Use safety lights and devices. Slow moving machines when driven on public roads are hard to see, especially at night. Avoid personal injury or death resulting from a collision with a vehicle.


MIF

ˇ Flashing warning lights are recommended whenever driving on public roads to increase visibility. Extra flashing warning lights may need to be installed.

Avoid High Pressure Fluids

ˇ Hydraulic hoses can fail due to physical damage, kinks, age, and exposure. Check hoses regularly. Replace damaged hoses.


MIF

ˇ 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.

ˇ Search for leaks with a piece of cardboard. Protect hands and body from high pressure fluids.

ˇ 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.
