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.

OPERATING YOUR NEW ZTR MOWER (cont.)
CONTROLS
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
●
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.
•
* Model ZT20050 has a remote choke assembly
located on the right fender, behind the rider.
●
WARNING: Do not operate the machine unless
the Operator’s Presence System is functioning as
described.
•
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.
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.
•
•
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.
●
●
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.
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.
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.
•
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”.
●
●
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.
•
For best performance, grass over 6 ½” 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.
NEUTRAL LOCK: The steering levers must be
in the outward and locked position for the mower
to start. ( See page 12)
•
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 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.
