SAFETY RIDING LAWNMOWERS, IF IMPROPERLY OPERATED, CAN CAUSE SERIOUS INJURY OR DEATH The most common causes of injury to the operator or bystander... BLADE CONTACT TIP-OVER BACK-OVER ...read and understand this manual to prevent injuries.
SAFETY SAFETY SYM BOLS Safety Alert Symbol When you see this symbol, BE ALERT to the potential for injury. Follow recommended safety precautions and safe operating practices. Danger indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. Warning indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
SAFETY This cutting mower is capable of amputating hands & feet, and throwing objects. Failure to observe the following safety instructions could result in serious injury or death. GENERAL OPERATION: • Read, understand, and follow all instructions in the manual and on the mower before starting. • Only allow responsible adults, who are familiar with the instructions, to operate the mower. • Clear the area of objects such as rocks, toys, wire, etc., which could be picked up and thrown by the blade.
SAFETY 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 Mow across the slope with your Dixon ZTR - never up or down. Remove obstacles such as rocks, tree limbs, etc. Watch for holes, ruts or bumps. Uneven terrain could overturn the mower. Tall grass can hide obstacles. Use slow speed.
SAFETY CHILDREN: Tragic accidents can occur if the operator is not alert to the presence of children. Children are attracted to lawn mowers and the mowing activity. NEVER assume children will stay where they were last seen. Be alert to avoid accidents. • Keep children out of the mowing area and under the watchful care of another responsible adult. • Be alert and turn mower off if a child enters the area. • Before and during backing, look behind and DOWN for small children. • Never carry children.
SAFETY SERVICE: • Use extra care in handling gasoline and other fuels. They are flammable and vapors are explosive. Use only an approved container. Never remove gas cap or add fuel with the engine running. Allow engine to cool before refueling. Do not smoke. Never refuel the mower indoors. Never store the mower or fuel container inside a building where there is an open flame. • Never run a mower inside a closed area. The exhaust fumes are toxic.

In order to achieve the best results, please read and follow the mulching tips listed below: 1. Set the engine speed control to the wide open or full setting. 2.
OPERATION INSTRUCTIONS MOWING WITH A GRASS CATCHER ATTACHMENT: In order to achieve optimum performance when mowing with a grass catching attachment, please read and follow the tips listed below. 1. Some applications may require installation of an "Optional" weight box on the front of the mower to offset cut grass weight. 2. Set engine speed control to the wide open or full setting. 3. Do Not Attempt To Cut Grass When It Is Wet.
OPERATION INSTRUCTIONS SIDE DISCHARGE OF THE CLIPPINGS: In order to achieve optimum performance when side discharging the grass clippings, please read and follow the tips listed below. Additional information can be found in the troubleshooting guide. CAUTION Be sure that deflector is properly installed on the discharge chute. 1.
