IMPORTANT - READ CAREFULLY The Dixon^ZTR® Mower is both easy and fun to operate. However, any power mower must be operated properly to be safe. It is not a toy or a recreational vehicle. Before you start to use the mower, read the operator's manual carefully and become completely familiar with the controls. The information in this operator's manual applies to all Dixon @ZTR@ Model 6601 Mowers. Your Dixon dealer will gladly provide a check-out ride and answer any questions.
SAFETY RIDING LAWNMOWERS, IF IMPROPERLY OPERATED, CAN CAUSE SERIOUS INJURY OR DEATH The most common causes of injury to the operator or bystander...
SAFETY SAFETY SYMBOLS: 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 and 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.

CARE AND MAINTENANCE This portion of the Model ZTR 6601 owners manual deals with normal service items which can be performed by the owner. Please remember that if you are in doubt as to the correct service procedures to be followed, these and other service situations can be handled by a Dixon ZTR dealer who is familiar with the service of your mower.
CARE AND MAINTENANCE CUTTER BLADE MAINTENANCE: NOTE: Observe proper blade position prior to removal. 1. Safely raise front of mower. 2. Hold or block blade from turning. Wear heavy, thick gloves when holding onto cutter blade, avoid the sharp edge of the blade. NOTE: Be sure blade is centered on pilot before tightening bolt to 60 ft. l bs. torque.
CARE AND MAINTENANCE BELT TENSION ENGINE TO MOWER DECK BELT: P/N 9758 No adjustment required. Correct belt tension is maintained through a fixed engine location and a spring loaded idler system. A pulsing movement of the belt idler will be observed both during engagement of the electric blade clutch and actual operation of the mower deck. NOTE: Engagement of the electric blade clutch switch may produce a sharp high pitched chirp or squeal as the belt tension loading is absorbed by the idler system.
CARE AND MAINTENANCE FUEL SHUT OFF VALVE: A fuel shut off valve is located at the bottom rear of each fuel tank. Always turn the valve to the "OFF" position when the mower is stored or not in use.
CARE AND MAINTENANCE REAR WHEELS: The rear wheels of the Model ZTR 6601 are of an "offset" center design to both compliment the articulation of the mowing deck and to provide stability when mowing on sloped ground. 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.

CARE AND MAINTENANCE LUBRICATION DRIVE SYSTEM: The gears in the HydroGear gearbox are permanently lubricated using a special grease which completely eliminates the need for any type of maintenance. The HydroGear BDU-10L Series 70 hydrostatic transmissions are serviced with any high quality 10W30 motor oil. The oil is filtered by a 10 micron oil filter. Recommended service interval for filter is after the first 250 hours of operation, then after every 400 hours of operation.
CARE AND MAINTENANCE HOT oil may cause burns. Allow engine to cool before draining oil. CHANGING THE ENGINE OIL: 1. The "snap lock" oil drain valve is located on the left side of the engine crankcase. 2. Place a suitable container under the drain valve. The fitting of a short piece of hose to the valve will help direct the oil. 3. Push the valve body in and twist to clear the detent notch. 4. Pulling the valve body outward will start the flow of oil.
CARE AND MAINTENANCE DECK LEVELING AND HEIGHT ADJUSTING PROCEDURE 1. On the right side of the machine, the tie bar between the lift arms should be adjusted so there is 20-1/2" between clevis eyes. If adjustment is necessary, loosen jam nuts on both ends of the bar, and turn bar by hand until 20-1/2" dimension is achieved. Tighten jam nuts securely back against both ends of the bar.
CARE AND MAINTENANCE DRIVE SYSTEM ADJUSTMENTS: Adjustment of the drive system is limited to the actual function of the hydrostatic transmissions as outlined below. T-BOX TO HYDROSTAT BELT ADJUSTMENT: Tighten the (2) J-bolts on the T-box mounting pla te until each belt has 1/8th to 1/4th of an inch free play or movement at a mid -point between the pulleys on the hydrostats and Tbox.
CARE AND MAINTENANCE PARKING BRAKE CABLE ADJUSTMENT: Position parking brake lever in the off or disengaged position. This will allow the belt idler used on the engine to T-box to swing fully and apply tension to the belt. At this time, check that the cable which pulls the idler to a neutral position has approximately 1-1/2 to 2 inches of free play. If adjustment is required, loosen the lock nuts on the cable block and turn cable sleeve in or out to achieve desired measurement. Re-tighten lock nuts.
CARE AND MAINTENANCE NEUTRALADJUSTMENT: Swing upper control levers out into the neutral slots. Raise upper body to the fully open position. Start engine and disengage parking brake. Caution should be used when releasing parking brake as mower may t end to creep or move prior to adjustment. If adjustment is required, loosen lock nuts at each end of the control rods and back off the tension on each spring block. Turn control rods in or out until neutral is obtained on each hydrostat.
CARE AND MAINTENANCE FORWARD TRAVEL SPEED ADJUSTMENTS: Stop engine, move levers to drive position, lightly push each upper control lever forward until a resistance is felt on the lever. At this time, check that the forward lever stops on the bottom of each lever are hitting the stop blocks. If adjustment is required, loosen the lock nuts on the lever stop and turn the bolt in until the lever hits the stop block before resistance is felt in the hydrostat. NOTE: Balance of travel speed.
CARE AND MAINTENANCE PROCEDURE FOR ELECTRIC CLUTCH ADJUSTMENT Electric clutches require periodic Air Gap adjustments to extend the life of the clutch. Listed below is both an Air Gap adjustment procedure and an Ohms test to check for a faulty coil within the clutch. No replacement parts are available to repair a faulty assembly. The entire clutch must be replaced. A. AIR GAP ADJUSTMENT 1. Remove the clutch from the engine. This is recommended because it is easier to verify the gap. 2.
CARE AND MAINTENANCE HYDROSTATIC TRANSMISSION OIL AND FILTER SERVICE SERVICE INTERVALS: 1. Initial oil and filter service - 50 hours. 2. Every 250 hours thereafter. OIL REQUIREMENTS: Any high quality engine oil with an API classification of SG/CD is recommended. RECOMMENDED OIL WEIGHT: 10W30 Another alternative that will provide excellent all climate performance and extended time between oil changes is a 15 W 50 synthetic engine oil.
CARE AND MAINTENANCE WHEELS AND TIRES: Correct tire pressure is important for correct operation of mower . Front Tires Rear Tires 11X4X5 20X11X8 Air Pressure 16-21 Ibs. Air Pressure 5 Ibs. (maximum pressure) NOTE: Check lug nuts periodically for tightness. ELECTRICAL SYSTEMS: Keep all connections clean and tight. CLEANING THE MOWER: Wash mower periodically. Clean above and below deck. NOTE: Allow mower to cool before washing.
