The operation of any cutter can encounter foreign objects to be thrown into the
eyes, resulting in severe eye damage. Always wear certified safety glasses or
wide-vision safety goggles for over spectacles before starting any cutting
machine and while operating such a machine.
The operation of any cutter produces sound waves that are damaging to the
human ear. Ear protection is recommended.
CAUTION!
Tragic accidents can occur if the operator is not alert to the presence of
children. Children are often attracted to the machine and the mowing
activity. Never assume that children will remain where you last saw
them.
SLOPE OPERATION! ( See page 27 )
Do not operate on slopes greater than 15 degrees.
Use extra caution when mowing on slopes. Operate self-propelled units
up and down slopes. There is a significant risk of overturns when
operating across slopes. If you feel uneasy on a slope then do not mow it.

OPERATING YOUR NEW ZERO TURN RIDER MOWER
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 will cause the engine to shut off. Never get off the mower
without placing the steering levers in the neutral position.
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 push/pull choke mounted on
the right side fender for easier cold weather starts. Pull out to choke (start) engine.
•
•
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 11)

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 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.
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. The ZT2350
has a remote choke assembly located on the right fender, behind the rider.
•
FORWARD MOVEMENT: Position steering handles inward to the drive position. 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 ½” to 3 ½”.
•
•
For best performance, tall grass should be mowed once in the highest position and once again
at desired cut height. Never cut more than1/3 the height in one cutting.
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.

SERVICE / ADJUSTMENTS
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.
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 are for the reverse travel. Clockwise movement for these 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.
