follows and be alert to the possibility of personal injury.

Read this manual completely. This machine can amputate hands and feet, and
throw objects. Failure to observe the following safety instructions could result in
serious injury or death.

• Read the manual. Learn to operate this machine safely.

• Always disconnect the spark plug wire and place the wire where it cannot contact the

spark plug, to prevent accidental starting the engine when setting up, transporting,
adjusting or making repairs.

• Keep all shields and guards in place.

• Understand the speed, steering and stability of this machine. Know the positions and

operations of all controls before you operate this machine. Check all of the controls in
a safe area before starting to work with this machine.

• Allow only responsible adults who are familiar with these instructions to operate this

machine. Never allow children to operate this machine.

• Clear the area of objects such as rocks, toys, wire, etc. that can be picked up and

thrown by the blade.

• Be sure the area is clear of other people before mowing. Be aware of the mower

discharge direction and do not point at anyone. Stop the machine if anyone enters the
mowing area. Children are often attracted to the machine and the mowing activity.
Never assume that children will remain where you last saw them. Keep children
under the watchful care of another responsible adult.

• No riders!

• Do not put hands or feet near or under rotating parts. Keep clear of the discharge

opening at all times.

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!

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.

•Turn off the blades when not mowing. Before leaving the machine, turn off the blades
and stop the engine.

•Watch for traffic when operating near or crossing roadways.

•Do not operate the mower if it has been dropped or damaged in any manner or if the
mower vibrates excessively. Excessive vibration is an indication of damage.
Repair mower as necessary.

•Dress properly. Do not operate the mower when barefoot or wearing open sandals.
Wear only solid shoes with good traction when mowing.

•Never allow operation by untrained persons.

•Do not operate the machine while under the influence of alcohol or drugs.

•Operate self-propelled machines up and down slopes. There is significant risk of
overturns when operating across slopes. Avoid sudden turns. Operate walk-behind
machines across slopes. There is a significant risk of slipping under a walk-behind
machine when operating up and down slopes.

• Never tamper with safety devices. Check their proper operation regularly.

•Stop and inspect the equipment if you strike an object. Repair, if necessary, before
restarting. Never make adjustments or repairs with the engine running. Mower blades

are sharp and can cut. Wrap the blades or wear gloves, and use extra caution when
servicing them. Do not operate at too fast a rate.

• Do not mow close to ditches, embankments or drop-offs. An edge could collapse. A
mower wheel over the edge could suddenly turn the unit over.

•Do not mow on wet grass if possible. Wet grass causes reduced traction and could cause
sliding. Do not park on a slope unless absolutely necessary.

• Always chock or block wheels and set parking brake if parked on slope.

WARNING: Hydraulic fluid can cause severe burns and penetrate skin causing
severe injury or death.

• Do not step on mower deck when operating, dismounting or mounting the
mower.

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.
