OPERATING YOUR NEW ZTR MOWER (cont.)

CONTROLS

_ OPERATOR PRESENCE SYSTEM: This

mower is equipped with an operator’s presence system. Any attempt to leave the seated position with the engine running, without first disengaging the PTO switch and placing the steering levers in the neutral position, will cause the engine to shut off.

_ WARNING: Do not operate the machine unless

the Operator’s Presence System is functioning as described.

_ PARKING BRAKE: Always set the parking

brake before starting. The parking brake is located on the drivers left hand side. Engage the parking brake by pushing the lever rearward and down until lever locks into position. Be sure to release parking brake before operating the machine.

_ IGNITION: The ignition switch is located on the

drivers right hand side toward the rear of the seat. The ignition switch has three positions: OFF, ON, START.

_ THROTTLE: The throttle\choke control is

located on the drivers right hand side towards the front of the seat. For maximum performance and battery charging, operate mower at full throttle. When starting a cold engine, place lever forward in the full choke position. After start up, move throttle rearward to full throttle position. Move lever all the way to the rear for lowest setting before shutting off engine. The 50” Model has a choke mounted on the right side fender for easier cold weather starts.

_ PTO SWITCH: The PTO, or Power Take Off

switch is used to engage the blades of the mower. When the PTO switch is pulled out the blades will be engaged. When the PTO switch is pushed in the blades will be disengaged. The PTO switch must be pushed in to complete the Operator’s Presence System to start engine.

_ NEUTRAL LOCK: The steering levers must be

in the outward and locked position for the mower to start. ( See page 12)

STARTING MOWER

• TO START: Position steering handles outward to

neutral locked position. Engage parking brake. Extend throttle to full choke position*. Start ignition and slide throttle lever back to full throttle position. Allow engine to warm up for 1 minute. Release parking brake

• * Model ZT20050 has a remote choke assembly located on the right fender, behind the rider.

• FORWARD MOVEMENT: To move the mower

forward gently push both steering levers forward equal distance from the neutral position. The further you move the levers forward the faster you will travel. CAUTION steering levers have quick response timing.

• BACKWARD MOVEMENT: To move the

mower backwards, gently pull back on the steering levers the same distance from neutral. The further you pull back the faster you will travel. NOTE it is normal for the reverse speed to be less than the forward for easier turning.

• TURNS: For left turn, move the right lever farther

forward then the left. For right turn, move the left lever farther forward than the right. To obtain a tight turning radius, GENTLY reverse one lever and push the other lever forward. CAUTION: Aggressive turns can damage lawns. Do not make turns with the inside wheel stopped. It it better to keep both wheels turning slightly.

• DECK HEIGHT ADJUSTMENT: To raise the

mower deck up and down, simply rotate the lever located in front of the seat above the floor plate. Clockwise raises the deck. Counterclockwise lowers the deck. The deck is adjustable from 1 _” to 3 _” .

• For best performance, grass over 6 _” in height should be mowed once in the highest position and once again at desired cut height.

• ENGAGING BLADES: Operator must be seated

for operation of blades. With engine to full throttle position, pull UP on PTO switch located between the throttle and the key switch. To disengage blades, push DOWN on PTO switch.

• STOPPING ENGINE: Place both levers in the

outward neutral locked position. Push PTO switch in to disengage. Place throttle lever to lowest setting and let idle for 30 seconds. Turn off ignition key and engage parking brake.

OPERATING YOUR NEW ZTR MOWER (cont.)

MOWING

• WARNING: Do not operate mower at too fast of a rate. Sudden movements forward and backward at fast speeds can cause accidents resulting in personal injury

• Start out slowly moving steering levers SLOWLY forward and backward until you learn to operate the unit. NOTE: This mower has been designed to be very maneuverable. Practice in open, flat areas is extremely necessary to become comfortable and efficient with the controls.

• BEGIN TO MOW: Before starting the engine, set the desired deck height.

• Start the mower engine.

• Position the throttle lever about halfway and engage PTO switch. Reposition throttle lever to full throttle position.

• Move steering levers forward to begin mowing.

• CAUTION: Always make sure the deck is not plugged with grass or other debris.

Failure to do this will cause damage to the PTO belt.

• STOPPING: Hydrostatic mowers use hydrostatic braking through the transmissions. To slow or stop the unit move the steering levers to the neutral position

• STOPPING THE ENGINE: Move the throttle lever to slow position, allow engine to idle for 30 seconds and turn ignition to off position. CAUTION: Failure to position the ignition key to any position except off will cause discharge of the battery.

MAINTENANCE SCHEDULE

INSPECT BEFORE EACH USE

-Loose fasteners: Be sure all fasteners are at proper torque. Especially guards and

blades.

-Parking brake: If brake does not keep unit from rolling, brake must be adjusted or repaired.

-Tires: Always check and maintain proper tire pressure (See tire sidewall for recommendation). Check for damage due to sharp rocks, objects or stumps.

-Operator Presence System: The engine should not start unless the PTO switch is disengaged and the control levers are locked in the neutral position. Any attempt to leave the seated position with the PTO switch engaged will kill the engine.

-Oil level: To prevent damage to engine, always check and maintain proper oil level. Never operate engine with the oil level below the add mark on the dipstick. Be sure to tighten the dipstick securely after inspection. Refer to engine manual for additional information.

INSPECT EVERY 8 HOURS

-Proper cleaning: Remove any build up of grass, dirt or debris with a brush or cloth from engine, battery, deck and and transaxles. Do not use harsh chemicals or abrasives. Keep all painted surfaces and wheels free of oil and gasoline. Protect all painted surfaces with an automotive wax. Do not spray unit with water or store outdoors unprotected. Water can invade sealed bearings and reduce component life.

-Air filter: The engine will not run properly with a dirty or damaged air filter. Check filter before starting the engine. Check for buildup of dirt or debris. Replace if bent, clogged, or damaged.

Do not spray water onto hydrostatic transmissions. This will

cause injection of water into the unit causing failure.

Page 11

INSPECT EVERY 25 HOURS

-Lubrication: Grease all pivot points with a high temp grease

-Battery, check and clean: Keep battery terminals clean and tight. Periodic

charging will extend its life. Clean terminals with a wire brush and coat with a petroleum jelly.

SERVICE / ADJUSTMENTS

TRACKING

Adjustments to the unit may need to be made if the unit does not track in a straight line. The primary reason for the unit not tracking straight is incorrect or unbalanced tire pressure. Before making any adjustments first check and adjust the tire pressure. DO NOT EXCEED MAXIMUM RECOMMENDED TIRE PRESSURE.

ADJUST LINKAGE: Place steering levers outward locking them in the neutral position. Turn off engine and raise seat. Under the seat are (4) adjustment bolts. The two adjustment bolts toward the seat mount are adjustments for the forward travel. The two bolts toward the engine or are for the reverse travel. Clockwise movement for these adjustments will decrease or slow the travel speed of the individual side. Counterclockwise movement will increase the travel of the individual side. The linkage is factory set to maximum performance. Adjustment is made by rotating the adjustment bolt clockwise on the opposite side that the unit tracks toward. Adjust forward and reverse to track straight as needed. When accomplished adjustment to the steering levers may need to be done. This is made by loosening the the two bolts on the steering lever and aligning with the other. Travel of the steering levers from front to rear may be accomplished in the same manner.

CAUTION: Before performing any service or adjustments do as follows:

1. Turn off PTO switch.

2. Position unit on smooth flat surface.

3. Place steering levers in outward, neutral-locked position.

4. Turn ignition key “OFF” and set parking brake.

5. Wait for all moving parts to stop and disconnect spark plug wire.
