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

What should I do if someone enters the area while I am operating the machine?

Stop the machine if anyone enters the area.

What should I do if I hit an object?

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.

What should I be aware of while mowing?

Be aware of the mower discharge direction and make sure that no one is in the path of the discharge direction.

When can I leave the machine unattended?

Do not leave machine unattended when it is running.

When should I operate the machine?

Only operate during daylight or with good artificial light.

What should I do when operating near or crossing roadways?

Be careful of traffic when operating near or crossing roadways.

Can I wear headphones while operating the machine?

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

What should older adults do before operating the machine?

Older adults are involved in a large percentage of riding mower accidents involving injury. These operators should evaluate their ability to operate a mower safely enough to protect the operator and others from serious injury.

What are the steps for parking safely?

Stop machine on a level surface, not on a slope. Disengage mower blades. Lower attachments to the ground. Lock the park brake. Stop the engine. Remove the key. Wait for engine and all moving parts to stop before you leave the operator’s seat. Close fuel shut-off valve, if your machine is equipped.

What should I do before checking the mowing area?

Clear mowing area of objects that might be thrown. Keep people and pets out of mowing area. Study mowing area. Set up a safe mowing pattern. Do not mow where traction or stability is doubtful. Test drive area with mower lowered but not running. Slow down when you travel over rough ground.

What can happen if rotating blades are not handled carefully?

Rotating blades can cut off arms and legs. Keep hands, feet and clothing away from mower deck when engine is running. Be alert at all times, drive forward carefully. People, especially children can move quickly into the mowing area before you know it. Before backing up, shut off PTO and look down and behind the machine carefully, especially for children. Do not mow in reverse. Shut off blades when you are not mowing. Do not operate machine if you are under the influence of drugs or alcohol. Park machine safely before inspecting or unplugging mower or bagger.

How can I protect children while mowing?

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 indoors when you are mowing. Turn the 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 an untrained person operate the machine. Do not carry or let children ride on any attachment or machine even with the blades off. Do not tow children in a cart or trailer.

What should I do to avoid tipping the machine?

Slopes are a major factor related to loss-of-control and tip-over accidents, which can result in severe injury or death. If you cannot back up the slope or if you feel uneasy on it, do not mow it. 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, ditches and embankments. Slow down before you make a sharp turn or operate on a slope. Choose a low gear so that you will not have to stop or shift while on the slope. Limit loads to those you can safely control. Use only approved hitches when pulling loads or using heavy equipment. Use counterweights or wheel weights as required in this manual or your attachment manual. Use wheel weights for added stability when operating on slopes or using rear mounted attachments. Drive up and down a hill – not across. Turn slowly and turn downhill. Do not shift to neutral and coast downhill. Do not stop when going up hill or down hill. If machine stops going up hill, disengage mower blades and back down slowly. Mowing when grass is wet can cause reduced traction and sliding. Do not try to stabilize the machine by putting your foot on the ground.

Who is allowed to ride on the machine?

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.

What clothing is appropriate when operating the machine?

Wear close fitting clothing and safety equipment appropriate for the job. Always wear safety goggles or safety glasses with side shields when operating the mower. Wear a suitable protective device such as earplugs. Loud noise can cause impairment or loss of hearing. Do not wear radio or music headphones. Safe service and operation requires your full attention.

How can I avoid 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. Use extra care when loading or unloading the machine into a trailer or truck. 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.

What are some mowing tips?

Keep mower blades sharp. Dull blades will tear grass; tips of grass will then turn brown. Cutting grass too short may kill grass and let weeds grow easily. Adjust cutting height to remove only 1/3 of the grass at a time. Mow grass often. Short grass clippings will decay quickly. Mow with engine at full throttle. Adjust travel speed to match mowing conditions: Travel at SLOW speed when you mow thick, tall grass, make sharp turns or trim around objects. Travel at MODERATE speed when you mow thin grass. Use a different mowing pattern each time you mow. Overlap mowing paths 50 to 100 mm (2 to 4 in). Drive over ridges and through shallow ditches straight-on, not at an angle. A thick layer of mulched leave can prevent sunlight from getting to grass and smother it. Taller grass heights allow mulched leaves to dispense easier in lawn. Mulch leaves several times if needed. Use a thatcher in late spring or summer to pull up dead grass and aerate ground.
