SAFETY RIDING LAWN MOWERS, IF IMPROPERLY OPERATED, CAN CAUSE SERIOUS INJURY OR DEATH. The most common causes of injury to the operator or bystander... BLADE CONTACT TIP OVER RUN OVER BACK OVER ...read and understand this manual to prevent injuries.
SAFETY Safety Alert Symbol When you see this symbol, BE ALERT to the potential for injury. Follow recommended safety precautions and safe operating practices. DANGER (highlighted in red) indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. WARNING (highlighted in orange) indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
SAFETY 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. Be sure the area is clear of other people before mowing.
SAFETY GENERAL OPERATION (continued): Turn off blades when not mowing. Stop engine before removing grass catcher or unclogging chute. Mow only in daylight or good artificial light. Do not operate the mower while under the influence of alcohol or drugs. Watch for traffic when operating near or crossing roadways. Use extra care when loading or unloading the mower into a trailer or truck. Do not ride the mower when loading and unloading.
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 fuel cap or add fuel with engine running. Allow engine to cool before refueling. Do not smoke while refueling. Never refuel the mower indoors. Never store the mower or fuel container inside a building where there is an open flame. If fuel is spilled on clothing, change clothing immediately.
SAFETY SERVICE (continued): Never run a mower inside a closed area. The exhaust fumes are toxic. Keep nuts and bolts tight, especially blade attachment bolts, and keep equipment in good condition. Never tamper with safety devices. Check their proper operation regularly. Keep mower free of grass, leaves, or other debris build-up. Clean up oil or fuel spillage. Allow mower to cool before storing. Stop and inspect the equipment if you strike an object.

OPERATION INSTRUCTIONS The safe and successful operation of the ZTR 7500 Series will depend upon the operator having the correct knowledge of all controls used on the mower and making good judgements about the terrain to be mowed. NEVER allow anyone to operate the mower without complete knowledge of all controls and their functions. During initial operation, learning to drive, set throttle at slow speed. Sound judgement by the owner will prevent accidents. BEFORE OPERATING MOWER: 1.
OPERATION INSTRUCTIONS TESTING OF SAFETY INTERLOCK SYSTEMS: Do not operate mower if safety switches are not operating properly. Your Zero Turning Radius Mower is equipped with control interlocks for your safety. 20 1. The mower blades must be disengaged before the engine will start. 2. The brake lever must be engaged (upward position) before engine will start. 3. The engine will stop if the mower blade clutch is engaged when the operator leaves the driver's seat. 4.
OPERATION INSTRUCTIONS BLADE DRIVE SWITCH TEST (ELECTRIC CLUTCH): 1. With the electric blade drive switch turned on and the parking brake in ON position, engine should not turn over or attempt to start when key switch is moved to the start position. 2, In a safe area, away from bystandards, start the engine, place throttle setting at maximum or full. Engage the blade drive through the electric clutch switch. Raise weight slightly off of seat. ENGINE SHOULD STOP. 3.
OPERATION INSTRUCTIONS STARTING INSTRUCTIONS (cold engine): 1. Pull choke control lever up. 2. Push throttle control lever to 1/2 setting. 3. Insert ignition key and turn to START position. When engine starts, release ignition key. Key will return to RUN position. 4. Once engine starts to warm up, slowly push choke control lever down to fully closed position. 5.

OPERATION INSTRUCTIONS In order to achieve optimum cutting performance, please read and follow the tips listed below. Additional information can be found in the Troubleshooting Guide on Page 36-37. CAUTION Be sure that deflector is properly installed on the discharge chute. 24 1. Set engine speed control to the wide open or full setting. 2. Do Not Attempt To Cut Grass When It Is Wet. Wet grass will clog the underside of the deck and discharge area. 3.
OPERATION INSTRUCTIONS GRASS HEIGHT AND CUTTING SUGGESTIONS: Do not attempt to cut grass when it is wet. If the grass is tall, place the mower deck cut height lever in the top or second notch. Initially overlap cutting swaths instead of a full swath with each pass. Some applications may require a second cutting. As a rule of thumb, never cut off more than 1/3 of the total grass blade length. Correct mowing height can reduce weeds and disease by 50% to 80%.
OPERATION INSTRUCTIONS TO FREE WHEEL MACHINE (UNLOCK TRANSMISSION): Always turn off engine before engaging or disengaging the hydro release (free wheel) valves. Never attempt to move the valves with the engine running. The hydro release valves are located behind the seat, between the fuel tank and hydro pumps. Use a 5/8 wrench and insert through the slots on the top side of the seat plate and rotate bolt counter-clockwise two full turns to disengage pump. Repeat procedure for opposite pump.
