Operating


Operate Safely


MIF

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

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.

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. Keep all shields and guards in place.

DO NOT leave machine unattended when it is running.

Only operate during daylight or with good artificial light.

Be careful of traffic when operating near or crossing roadways.

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

Park Safely

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

Disengage PTO

Lower attachments to the ground.

Engage park brake.

STOP engine.

Remove key.

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

Rotating Blades Are Dangerous - Protect Children And Prevent Accidents

PROTECT CHILDREN:


MIF


MIF

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

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

Turn machine off if a child enters the mowing area.

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

DO NOT let children or untrained person operate the machine.

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:

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

Back carefully. Shut off PTO and look behind the machine carefully, ESPECIALLY FOR CHILDREN, before you back up.

DO NOT mow in reverse unless it is absolutely necessary.

Shut off PTO when you are not mowing.

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

Use Seat Belt Properly


MIF

Use a seat belt when you operate with a roll-over protective structure (ROPS) or cab to minimize chance of injury from an accident such as an overturn.

Do not use a seat belt if operating without a ROPS or cab.

Avoid Tipping


MIF

DO NOT drive where machine could slip or tip.

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

Keep away from drop-offs.

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

When pulling loads or using heavy equipment, use only approved hitches, limit loads to those you can safely control, and use counterweights or wheel weights when required per this manual or your attachment manual.

Drive up and down a hill - not across. Be careful when you change direction on a slope.

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

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

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

Operator Training Required

Study operation section of this manual before operating the machine.

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

Learn the use of all controls.

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

Keep Riders Off


MIF

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

Mount And Dismount Safely


M96794

Use mower step when you mount or dismount.

Keep step and platform clean.

Wear Appropriate Clothing


MIF

Wear close fitting clothing and safety equip- ment appropriate for the job.

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

Stay Clear Of Rotating Drivelines


MIF

Entanglement in rotating driveline can cause serious injury or death:

Wear close fitting clothing.

STOP the engine and be sure PTO driveline is stopped before getting near it.

Check Wheel Bolts

A serious accident could occur causing serious injury if wheel bolts are not tight.

Check wheel bolt tightness often during the first 100 hours of operation.

Transport Safely


MIF

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.

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.
