Read these safety rules and follow them closely. Failure to obey these rules could result in loss of control of equipment, severe personal injury or death to you, yourself or bystanders, or damage to property or equipment. This mowing deck is capable of amputating hands and feet and throwing objects. The triangle in text signifies important cautions or warnings which must be followed.
IMPORTANT – Safe operation practices for riding mowers. I. General operation
1. Read, understand, and follow all instructions in the manual and on the unit before starting.
2. Only allow responsible adults, who are familiar with the instructions, to operate the unit.
3. Clear the area of objects such as rocks, toys, wire, etc., which could be picked up and thrown by the blade(s).
4. Be sure the area is clear of other people before mowing. Stop the unit if anyone enters the area.
5. Never carry passengers.
6. Do not mow in reverse unless absolutely necessary. Always look down and behind before and while backing.
7. Be aware of the mower discharge direction and do not point it at anyone. Do not operate the mower without either the entire grass catcher or the guard in place.
8. Slow down before turning.
9. Never leave a running unit unattended. Always turn off blades, set parking brake, stop engine, and remove keys before dismounting.
10. Turn off blades when not mowing.
11. Stop engine before removing grass catcher or unclogging chute.
12. Mow only in daylight or good artificial light.
13. Do not operate the unit while under the influence of alcohol or drugs.
14. Watch for traffic when operating near or crossing roadways.
15. Use extra care when loading or unloading the unit into a trailer or truck.
II. 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 or if you feel uneasy on it, do not mow it.
DO
• See your authorized dealer for recommendations of wheel weights or counterweights to improve stability.
• Mow up and down slopes, not across.
• Remove obstacles such as rocks, tree limbs, etc.
• Watch for holes, ruts, or bumps. Uneven terrain could overturn the unit. Tall grass can hide obstacles.
• Use slow ground speed so that you will not have to stop or change speeds while on the slope.
• Use extra care with grass catchers or other attachments. These can change the stability of the unit.
• 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 the blade(s) and proceed slowly straight down the slope.
DO NOT
• Do not turn on slopes unless necessary, and then, turn slowly and gradually downhill, if possible.
• Do not mow near drop-offs, ditches, or embankments. The unit could suddenly turn over if a wheel is over the edge of a cliff or ditch, or if an edge caves in.
• Do not mow on wet grass. Reduced traction could cause sliding.
• Do not try to stabilize the unit by putting your foot on the ground.
• Do not use grass catcher on steep slopes.
III. Children
Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the unit and the mowing activity. Never assume that children will remain where you last saw them.
1. Keep children out of the mowing area and under the watchful care of another responsible adult.
2. Be alert and turn unit off if children enter the area.
3. Before and when backing, look behind and down for small children.
4. Never carry children. They may fall off and be seriously injured or interfere with safe unit operation.
5. Never allow children to operate the unit.
6. Use extra care when approaching blind corners, shrubs, trees, or other objects that may obscure vision.
IV. Service
1. 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. c) Never refuel the unit indoors. d) Never store the unit or fuel container inside where there is an
open flame, such as a water heater. d) Clean up oil and fuel spills immediately.
2. Never run a unit inside a closed area.
3. Keep nuts and bolts, especially blade attachment bolts, tight and keep equipment in good condition.
4. Never tamper with safety devices. Check their proper operation regularly.
5. Keep equipment free of grass, leaves, or other debris build-up.
6. Stop and inspect the equipment if you strike an object. Repair, if necessary, before restarting.
7. Never make adjustments or repairs with the engine running.
8. 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, when necessary, with manufacturer’s recommended parts.
9. Mower blades are sharp and can cut. Wrap the blade(s) or wear gloves, and use extra caution when servicing them.
10. Check brake operation frequently. Adjust and service as required.
11. Allow the unit to cool before storing.
WARNING – SLOPE OPERATION
Never operate on slopes greater than 17.6 percent (10°) which is a rise of 3-1/2 feet (106 cm) vertically in 20 feet (607 cm) horizontally. When operating on slopes that are greater than 15 percent (8.5°) but less than 30 percent use front counterweights and rear wheel weights (see your dealer). Select slow ground speed before driving onto slope. In addition to front and rear weights, use extra caution when operating on slopes with rear-mounted grass catcher. Mow UP and DOWN the slope, never across the face, use caution when changing directions and DO NOT START OR STOP ON SLOPE.
