Operate Safely


MIF

ˇ Check brake action before you operate. Adjust or service brakes as necessary.

ˇ Inspect machine before you operate. Be sure hardware is tight. Repair or replace damaged, badly worn, or missing parts. Be sure guards and shields are in good condition and fastened in place. Make any necessary adjustments before you operate.

ˇ Clear work area of objects that might be thrown. Keep people and pets out of the work area. Stop machine if anyone enters the area.

ˇ If you hit an object, stop the machine and inspect it. Make repairs before you operate. Keep machine and attachments properly maintained and in good working order.

ˇ DO NOT leave machine unattended when it is running.

ˇ Only operate during daylight or with good artificial light.

ˇ Be careful of traffic when operating near or crossing roadways.

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

Park Safely

ˇ Stop machine on a level surface, not on a slope.

ˇ Disengage PTO.

ˇ Engage and lock park brake.

ˇ STOP engine.

ˇ Remove key.

ˇ Before you leave the operator's location, wait for engine and all moving parts to STOP.

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.

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 front attachment installed.


MIF

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 proceed 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.

ˇ A safety lighting kit is available from your John Deere dealer.

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.
