Safe Operation Practices For Ride-On Mowers

Failure to observe the following safety instructions could result in serious injury or death. Your complete and unimpaired attention is required at all times. Purchaser must give these instructions to the people operating and maintaining this tractor.

General Operation

Read, understand, and follow all instructions in this owners manual, the engine manual, the attachment manual and on the machine before starting.

Only allow responsible adults, who are familiar with the instructions, to operate the machine.

Clear the area of objects such as rocks, toys, wire etc., which could be picked up and thrown by the mower or other attachment.

Be sure the area is clear of other people & pets before operating. Stop machine if anyone enters the area. The operator is responsible for the safety of bystanders.

Before starting place the PTO lever in “Off” position and the gear shift lever in the neutral “N” position.

Never carry passengers. Operate only from operators position, on the seat. Do not operate in reverse unless absolutely

necessary. Always look down and behind before and while backing.

Be aware of the attachment discharge direction and do not point it at anyone. Do not operate without either the entire attachment or the guarding in place and functioning properly.

Slow down before turning to prevent tipping or loss of control.

Never leave a running machine unattended. Always turn off attachment, set parking brake, stop engine, move shift control to first gear position, and remove keys to prevent unauthorized use before dismounting.

Turn off power to attachment when not in use. Disengage attachment clutch, stop engine, remove

key and wait for moving par ts to stop before leaving operators position for any reason such as removing, cleaning, servicing, or unclogging the attachment.

Operate only in daylight or good artificial light. Do not operate the machine while under the influence

of medication, alcohol or drugs. Safe operation of this equipment requires your complete and unimpaired attention at all times. Watch for traffic when operating near or crossing

roadways or drives. Follow traffic laws when operating on or near a road.

Use extra care when loading or unloading the machine into a trailer or truck. When handling equipment connect the chassis to the transporting vehicle. Never connect from control levers, rods, or like items that could be damaged.

Use only attachments or accessories designed for your unit. See your Gravely Dealer.

Wear sturdy footwear. Do not operate tractor barefoot or when wearing open sandals or canvas shoes. Do not wear loose clothing that may get caught in rotating parts of unit. Wear hand, head, ear and eye protection.

Slope Operation

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 you cannot back up the slope of it you feel uneasy on it, do not operate on it.

Operate up and down slopes, not across. Do not operate on steep slopes.

Remove obstacles such as rocks, tree limbs, etc. from the area of operation.

Watch for holes, ruts, or bumps. Uneven terrain could overturn the machine. Tall grass or deep snow can hide obstacles.

Use slow speed. Choose a low ground speed so that you will not have to stop or shift while on the slope. Engage the directional control pedal slowly.

Follow the manufacturer’s recommendations for wheel weights or counterweights to improve stability.

Use extra care with grass catchers or other attachments. These can change the stability of the machine. Use only approved hitch points.

Limit loads to those you can safely control. Keep all movement on the slopes slow and gradual.

Do not make sudden changes in speed or direction. Avoid starting or stopping on a slope. If tires lose

traction, disengage attachment power and proceed slowly straight down the slope. If you must stop when going up the slope and can not safely back down, disengage the PTO, release the direction control pedal, and depress the brake pedal. Then place the gear selector in low speed and slowly release the brake pedal, while slowly engaging the direction control pedal.

Safety Precautions

Children

Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the machine activity. Never assume that children will remain where you last saw them.

Keep children out of the area of operation and under the watchful care of another responsible adult.

Be alert and turn machine off if children enter the area.

Before and when backing, look behind and down for small children.

Never carry children. They may fall off and be seriously injured or interfere with safe machine operation.

Never allow children to operate the machine. Use extra care when approaching blind corners,

shrubs, trees, or other objects that may obscure vision.

Service

Do not change engine governor setting or over speed the engine.

Replace damaged or worn out muffler immediately. Continued use could result in fire or explosion.

Use extra care in handling gasoline and other fuels. They are flammable and vapors are explosive.

A. Use only an approved container. B. Never remove gas cap or add fuel with the

engine running. Allow engine to cool before refueling. Do not smoke. Wipe off any spilled gasoline and allow vapors to dissipate before starting engine.

C. Replace fuel tank cap and container cap

securely. D. Never refuel the machine indoors. E. Never store the machine or fuel container inside

where there is an open flame, such as in a water

heater. Allow engine to cool before storing in

any enclosure. Never run a machine inside a closed area. Exhaust

fumes contain carbon monoxide, an odorless and deadly gas.

Keep nuts and bolts, especially blade attachment bolts, tight and keep equipment in good condition.

Never tamper with safety devices. Check their proper operation regularly. See page 7 for operatorpresence control check. If safety interlock is not functioning properly do not operate the tractor. Have repaired prior to use.

Keep machine free of grass, leaves or other debris build up. Clean up oil or fuel spillage. Allow machine to cool before storing.

Stop and inspect the equipment if you strike an object or if their is a sudden change in the sound or vibration of the equipment. Repair any damage before restarting.

Never make adjustments or repairs with the engine running or when engine and exhaust parts are hot from operation.

Grass catcher components are subject to wear, damage, and deterioration, which could expose moving parts or allow objects to be thrown. Frequently check components and replace, with manufacturer’s recommended parts, when necessary.

Mower blades are sharp and can cut. Wrap the blade(s) or wear gloves, and use extra caution when servicing them.

Check brake operation frequently. Adjust and service as required.

Refer to Storage Section of this owners manual if unit is to be stored for extended period.

Use only Gravely accessories, attachments and replacement parts. Replace parts that become damaged or lost.

Do Not

Do not turn on slopes unless necessary, and then, turn slowly and gradually downhill, if possible.

Do not operate near drop-offs, ditches, or embankments. The tractor could suddenly turn over if a wheel is over the edge of a cliff or ditch, or if an edge caves in.

Do not operate on wet grass. Reduced traction could cause sliding.

Do not try to stabilize the machine by putting your foot on the ground.

Do not use grass catcher on steep slopes.
