safely enough to protect themselves and others
from serious injury.
29. If situations occur which are not covered in this
manual, use care and good judgment. Contact
your authorized dealer for assistance.
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.
For your safety, use the slope gauge included as part
of this manual to measure slopes before operating this
unit on a sloped or hilly area. If the slope is greater
than 15 degrees as shown on the slope gauge, do not
operate this unit on that area or serious injury could
result.
DO:
1. Mow up and down slopes, not across. Exercise
extreme caution when changing direction on
slopes.
2. Watch for holes, ruts, bumps, rocks, or other
hidden objects. Uneven terrain could overturn the
machine. Tall grass can hide obstacles.
3. Use slow speed. Choose a low enough speed
setting so that you will not have to stop or shift
while on the slope. Tires may lose traction on
slopes even though the brakes are functioning
properly.
Always keep machine in gear when going down
slopes to take advantage of engine braking action.
4. Follow the manufacturer’s recommendations for
wheel weights or counterweights to improve
stability.
5. Use extra care with grass catchers or other
attachments. These can change the stability of the
5
machine.
6. Keep all movement on the slopes slow and
gradual. Do not make sudden changes in speed or
direction. Rapid engagement or braking could
cause the front of the machine to lift and rapidly flip
over backwards which could cause serious injury.
7. Avoid starting or stopping on a slope. If tires lose
traction, disengage the blade(s) and proceed
slowly straight down the slope.
DO NOT:
1. Do not turn on slopes unless necessary; then, turn
slowly and gradually downhill, if possible.
2. Do not mow near drop-offs, ditches or
embankments. The mower could suddenly turn
over if a wheel is over the edge of a cliff, ditch, or if
an edge caves in.
3. Do not try to stabilize the machine by putting your
foot on the ground.
4. Do not use a grass catcher on steep slopes.
5. Do not mow on wet grass. Reduced traction could
cause sliding.
6. Do not shift to neutral and coast downhill. Overspeeding may cause the operator to lose control of
the machine resulting in serious injury or death.
7. Do not tow heavy pull behind attachments (e.g.
loaded dump cart, lawn roller, etc.) on slopes
greater than 5 degrees. When going down hill, the
extra weight tends to push the tractor and may
cause you to loose control. (e.g. tractor may speed
up, braking and steering ability are reduced,
attachment may jack-knife and cause tractor to
overturn).
CHILDREN
1. 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.
They do not understand the dangers. Never
assume that children will remain where you last
saw them.
a. Keep children out of the mowing area and in
watchful care of a responsible adult other
than the operator.
b. Be alert and turn machine off if a child
enters the area.
c. Before and while backing, look behind and
down for small children.
d. Never carry children, even with the blade(s)
shut off. They may fall off and be seriously
injured or interfere with safe machine
operation.
e. Use extreme care when approaching blind
corners, doorways, shrubs, trees or other
objects that may block your vision of a child
who may run into the machine.
f. Never fuel machine indoors.
g. Never remove gas cap or add fuel while the
engine is hot or running. Allow engine to
cool at least two minutes before refueling.
h. Never over fill fuel tank. Fill tank to no more
than ½ inch below bottom of filler neck to
allow space for fuel expansion.
i. Replace gasoline cap and tighten securely.
j. If gasoline is spilled, wipe it off the engine
and equipment. Move unit to another area.
Wait 5 minutes before starting the engine.
k. To reduce fire hazards, keep machine free
of grass, leaves, or other debris build-up.
Clean up oil or fuel spillage and remove any
fuel soaked debris.
l. Never store the machine or fuel container
inside where there is an open flame, spark
or pilot light as on a water heater, space
heater, furnace, clothes dryer or other gas
appliances.
m. Allow a machine to cool at least 5 minutes
before storing.
f.
To avoid back-over accidents, always
disengage the cutting blade(s) before
shifting into reverse. The “Reverse
Caution Mode” should not be used when
children or others are around.
g. Keep children away from hot or running
engines. They can suffer burns from a hot
muffler.
h. Remove key when machine is unattended
to prevent unauthorized operation.
2. Never allow children under 14 years old to operate
the machine. Children 14 years old and over
should read and understand the operation
instructions and safety rules in this manual and
should be trained and supervised by a parent.
TOWING
1. Tow only with a machine that has a hitch designed
for towing. Do not attach towed equipment except
at the hitch point.
2. Follow the manufacturers recommendation for
weight limits for towed equipment and towing on
slopes.
3. Never allow children or others in or on towed
equipment.
4. On slopes, the weight of the towed equipment may
cause loss of traction and loss of control.
5. Travel slowly and allow extra distance to stop.
6. Do not shift to neutral and coast downhill.
GENERAL SERVICE:
1. Never run an engine indoors or in a poorly
ventilated area. Engine exhaust contains carbon
monoxide, an odorless, and deadly gas.
2. Before cleaning, repairing, or inspecting, make
certain the blade(s) and all moving parts have
stopped. Disconnect the spark plug wire and
ground against the engine to prevent unintended
starting.
3. Periodically check to make sure the blades come
to complete stop within approximately (5) five
seconds after operating the blade disengagement
control. If the blades do not stop within the this
time frame, your unit should be serviced
professionally by an authorized dealer.
4. Check brake operation frequently as it is subjected
to wear during normal operation. Adjust and
service as required.
5. Check the blade(s) and engine mounting bolts at
frequent intervals for proper tightness. Also,
visually inspect blade(s) for damage (e.g.,
excessive wear, bent, cracked).
Replace the blade(s) with the original equipment
manufacturer’s (O.E.M.) blade(s) only, listed in
this manual. “Use of parts which do not meet the
original equipment specifications may lead to
improper performance and compromise safety!”
6. Mower blades are sharp. Wrap the blade or wear
gloves, and use extra caution when servicing
them.
7. Keep all nuts, bolts, and screws tight to be sure the
equipment is in safe working condition.
8. Never tamper with the safety interlock system or
other safety devices. Check their proper operation
SERVICE
SAFE HANDLING OF GASOLINE:
1. To avoid personal injury or property damage
use extreme care in handling gasoline. Gasoline
is extremely flammable and the vapors are
explosive. Serious personal injury can occur when
gasoline is spilled on yourself or your clothes
which can ignite. Wash your skin and change
clothes immediately.
a. Use only an approved gasoline container.
b. Never fill containers inside a vehicle or on a
truck or trailer bed with a plastic liner.
Always place containers on the ground
away from your vehicle before filling.
c. When practical, remove gas-powered
equipment from the truck or trailer and
refuel it on the ground. If this is not possible,
then refuel such equipment on a trailer with
a portable container, rather than from a
gasoline dispenser nozzle.
d. Keep the nozzle in contact with the rim of
the fuel tank or container opening at all
times until fueling is complete. Do not use a
nozzle lock-open device.
e. Extinguish all cigarettes, cigars, pipes and
other sources of ignition.

ment manufacturer’s (O.E.M.) parts only, listed in
this manual. “Use of parts which do not meet the
original equipment specifications may lead to
improper performance and compromise safety!”
12. Do not change the engine governor settings or
over-speed the engine. The governor controls the
maximum safe operating speed of the engine.
13. Maintain or replace safety and instruction labels,
as necessary.
14. Observe proper disposal laws and regulations for
gas, oil, etc. to protect the environment.
regularly.
9. After striking a foreign object, stop the engine,
disconnect the spark plug wire(s) and ground
against the engine. Thoroughly inspect the
machine for any damage. Repair the damage
before starting and operating.
10. Never attempt to make adjustments or repairs to
the machine while the engine is running.
11. Grass catcher components and the discharge
cover are subject to wear and damage which could
expose moving parts or allow objects to be thrown.
For safety protection, frequently check components and replace immediately with original equip-

SECTION 2: OPERATION
GENERAL SAFETY
BEFORE OPERATING YOUR TRACTOR
•
•
Before you operate the tractor, study this manual
carefully. It has been prepared to help you
operate and maintain your tractor efficiently.
•
Familiarize yourself with the operations of all the
instruments and controls.
•
This engine is certified to operate on unleaded
gasoline. For best results, fill the fuel tank with
only clean, fresh, unleaded regular or premium
gasoline. DO NOt use leaded gasoline.
•
Some fuels are gasoline blended with alcohols or
ethers. The maximum alcohol percentage for ethanol and gasahol blends is 10%. The maximum
ether percentage for MTBE or ETBE blends is
15%. If undesirable operating symptoms occur,
use gasoline with a lower percentage of alcohol
or ether. Do not use gasoline that contains
Methanol.
•
Check the engine oil level. See Engine Manual.
IMPORTANT: Your tractor is shipped with motor
oil in the engine. However, you MUST check the
oil level before operating. The capacity of the
engine and oil filter is approximately 62 oz. (1.83
liters) for the model ZT42 and 80 oz. (2.36 liters).
for the model ZT50. Be careful not to overfill.
•
Clean the air cleaner element if necessary. See
Engine Manual.
•
Check the tire inflation pressures.
•

RECEIVE INSTRUCTION - Read the operator’s
manual. Learn to operate this machine SAFELY.
Don’t risk INJURY or DEATH. Allow only those
who have become competent in its usage to
operate this tractor .
Familiarize yourself with the operations of all the
instruments and controls.
Before starting the engine or beginning operation,
be familiar with the controls. The operator should
be in the operator’s seat. The PTO switch must
be in the disengaged position, the parking brake
engaged, and the RH and LH drive control levers
moved fully outward in the neutral position.
Keep all shields in place. Keep away from moving
parts.
NO RIDERS! Keep all people and pets a safe
distance away. Look behind and down to both
sides of the tractor before and while backing up.
DO NOT direct the mower discharge at people.
Avoid slopes where possible. Never operate on
slopes greater than 15°. Slopes with a greater
incline present dangerous operating conditions.
Tractors can be rolled over.
Before leaving the operator’s seat: Shut off the
PTO, move the RH and LH drive control levers
fully outward in the neutral position, engage the
parking brake, shut off the engine and remove
the ignition key. Wait for all movement to stop
before servicing or cleaning.
Operate the drive control levers smoothly and
avoid any sudden movements of the levers
when starting and stopping. Keep a firm grip on
the control levers; do not allow the levers to
return to neutral on their own.
Be careful when operating near roadways. Stop
the tractor motion and wait for vehicles to pass
before operating along the road.
Do not operate the tractor with the mower deck
removed. Removal of the deck will change the
balance of the tractor, and could contribute to a
tractor rollover.
Avoid operation on traction surfaces that are
unstable; use extreme caution if the surface is
slippery.
Slow down before turning and come to a
complete stop before any zero turn maneuver.
Do not stop the tractor or park the tractor over
combustible materials such as dry grass, leaves,
debris, etc.
Do not fill the fuel tank when the engine is
running or while the engine is hot. Allow the
engine several minutes to cool before refueling.
Tighten the fuel cap securely.
SAFETY INTERLOCK SYSTEM
This tractor is equipped with a safety interlock system
for the protection of the operator. If the interlock system
should ever malfunction, do not operate the tractor.

before putting the tractor under load.
NOTE: Always remove the key from the ignition
switch to prevent accidental starting or battery
discharge if the equipment is left unattended.
PRACTICE OPERATION (INITIAL USE)
Operating a zero-turn tractor is not like operating a
conventional type riding tractor. Although and because a zero-turn tractor is more maneuverable, getting used to operating the control levers takes some
practice.
USING JUMPER CABLES TO START ENGINE
WARNING: Batteries contain sulfuric acid
and produce explosive gasses. Make
certain the area is well ventilated, wear
gloves and eye protection, and avoid
sparks or flames near the battery.
We strongly recommend that you locate a reasonably large, level and open "practice area" where there
are no obstructions, pedestrians, or animals. You
should practice operating the tractor for a minimum of
30 minutes.
If the battery charge is not sufficient to crank the
engine, recharge the battery. If a battery charger is
unavailable and the tractor must be started, the aid of
a booster battery will be necessary. Connect the
booster battery as follows:
•
Connect the end of one cable to the disabled
tractor battery’s positive terminal; then connect
the other end of that cable to the booster
battery’s positive terminal.
•
Connect one end of the other cable to the booster
battery’s negative terminal; then connect the
other end of that cable to the frame of the disabled tractor, as far from the battery as possible.
•
Start the disabled tractor following the normal
starting instructions previously provided; then
disconnect the jumper cables in the exact reverse
order of their connection.
•
Carefully move (or have moved) the tractor to the
practice area. When performing the practice session,
the PTO should not be engaged. While practicing,
operate the tractor at approximately 1/2-3/4 throttle
and at less than full speed in both forward and
reverse.
Carefully practice maneuvering the tractor using the
instructions in the following section "Driving the Tractor." Practice until you are confident that you can
safely operate the tractor.
DRIVING THE TRACTOR
WARNING: Avoid sudden starts, excessive speed and sudden stops.
Have the tractor’s electrical system checked and
repaired as soon as possible to eliminate the
need for jump starting.
WARNING: Do not leave the seat of the
tractor without disengaging the PTO,
moving drive control levers fully outward
in the neutral position, and engaging the
parking brake. If leaving the tractor
unattended, turn the ignition key off and
remove key.

slow the tractor or to return to neutral.
Move the throttle control lever forward to the full
throttle position (3500-3600 RPM).
NOTE: The tractor and engine are designed to run at
full throttle. If performing a practice session, it is
preferable that the tractor is operated at less than full
throttle (approximately 2500-3000 RPM), but this only
applies to practice operation.
Turning the Tractor While Driving Forward
WARNING: When reversing the direction
of travel, we recommend performing
gradual ‘U’ turns where possible.
Sharper turns increase the possibility of
turf defacement, and could affect control
of the tractor. ALWAYS slow the tractor
before making sharp turns.
NOTE: For Model ZT42, make certain the throttle
control has not been moved too far forward into the
"Choke" position.
•
To slow the tractor move the controls lever
rearward to attain the desired speed, or move the
levers to the neutral position to stop the tractor.
To drive the tractor, firmly grasp the respective
drive control levers with your right and left hands
and proceed as follows :
•
WARNING: Always maintain a firm grip
on the control levers. DO NOT release the
control levers to slow or stop the tractor;
move the levers to the neutral position
using your hands.
To turn the tractor while driving forward, move the
control levers as necessary so that one lever is
rearward of the other. The tractor will turn in the
direction of the rearward control lever.
- To turn to the left, move the left drive control
lever rearward of the right lever. See Figure 12.
FORWARD LEFT TURN
Driving the Tractor Forward
WARNING: Keep all movement of the

slow position if operating a ZT50 tractor.
- Turn the ignition switch to “OFF’” and remove
the key from the switch.
Executing a Zero Turn
WARNING: When executing a zero turn,
the tractor MUST BE STOPPED.
Executing a zero turn while the tractor is
moving can significantly reduce your
control of the tractor and will cause
severe turf defacement to occur.
•
Stop the forward or reverse motion of the tractor
by moving the two drive control levers to neutral.
•
To turn clockwise, slowly move the left control
lever forward while simultaneously moving the
right control lever rearward. See Figure 17.
CLOCKWISE ZERO TURN
DRIVING ON SLOPES
Refer to the SLOPE GAUGE on page 10 to help
determine slopes where you may not operate safely.
WARNING: Do not operate on inclines
with a slope in excess of 15 degrees (a
rise of approximately 2-1/2 feet every 10
feet). The tractor could overturn and
cause serious injury.
•
Figure 17
•
•
To turn counterclockwise, slowly move the right
control lever forward while simultaneously moving
the left control lever rearward. See Figure 18.
•
COUNTERCLOCKWISE ZERO TURN
Always drive across slopes, never up and down.
Control the speed and direction of the tractor
using primarily the control lever on the downhill
side of the tractor, with the uphill control lever
remaining essentially in a fixed position.
Avoid turning downhill if possible. Start at the
bottom of a slope and work upward. Always slow
down before turning.
Use extra care and go slowly when turning
downhill.
OPERATING THE PTO
Operate the PTO clutch as follows:
• Move the throttle control lever to approximately
the mid throttle position.
• Pull the PTO switch upward to the “ENGAGED”
position.
• Advance the throttle lever to the operating speed
(full engine speed).
• The operator must remain in the tractor seat at all
times. If the operator should leave the seat
without turning off the power take-off switch, the
tractor’s engine will shut off.
• The PTO clutch cannot be operated when the
tractor is driving in the reverse direction. The
PTO will disengage when both drive control
levers are moved to the reverse position, and will
re-engage when one (or both) control levers are
moved to the neutral or forward position.
Figure 18
19
IMPORTANT: When stopping the tractor for any
reason while on a grass surface, always:
USING THE MOWER DECK
WARNING: Make certain the area to be
mowed is free of debris, sticks, stones,
wire or other objects that can be thrown
by the rotating blades.
• Place the shift lever in neutral,
• Engage the parking brake,
• Shut engine off and remove the key.
Doing so will minimize the possibility of having your
lawn ‘‘browned’’ by hot exhaust from your tractor’s
running engine.
IMPORTANT: Do not engage the mower deck
when lowered in grass. Premature wear and
possible failure of the ‘V” belt and PTO clutch will
result. Fully raise the deck or move to a non
grassy area before engaging the mower deck.
•
Mow across slopes, not up and down. If mowing
a slope, start at bottom and work upward to
ensure turns are made uphill.
•
On the first pass pick a point on the opposite side
of the area to be mowed.
•
Engage the PTO clutch using the PTO switch and
move the throttle control to the fast position.
•
Lower the mower deck to the desired height
setting using the lift handle.
•
Slowly and evenly push the RH and LH drive
control levers forward to move the tractor
forward, and keep the tractor headed directly
toward the alignment point.
NOTE: The speed of the tractor will affect the
quality of the mower cut. Mowing at full speed will
adversely affect the cut quality. Control the
ground speed with the control levers.
•
CHECKING THE SAFETY INTERLOCK CIRCUITS
Periodically check the safety interlock circuits to
ensure they are working properly. If a safety circuit is
not working as designed, contact you dealer to have
the tractor inspected. DO NOT operate the tractor if
any safety circuit is not functioning properly. To check
the safety circuits, proceed as follows:
When approaching the other end of the strip,
slow down or stop before turning. A U-turn is
recommended unless a pivot or zero turn is
required.
•
Align the mower with an edge of the mowed strip
and overlap approximately 3 inches.
•
Direct the tractor on each subsequent strip to
align with a previously cut strip.
•
To prevent rutting or grooving of the turf, if
possible, change the direction that the strips are
mowed by approximately 45° for the next and
each subsequent mowing.
WARNING: Be careful when crossing
gravel paths or driveways. Disengage
the PTO and raise the deck to the
highest position before crossing.

BATTERY MAINTENANCE
Relays and Switches
The battery is filled with battery acid and then sealed
at the factory. However, even a “maintenance free”
battery requires some maintenance to ensure its
proper life cycle.
There are several safety switches in the electrical
system. If a function of the safety interlock system
described earlier is not functioning properly, have the
electrical system checked by your White Outdoor
dealer.
•
Spray the terminals and exposed wire with a
battery terminal sealer, or coat the terminals with
a thin coat of grease or petroleum jelly, to protect
against corrosion.
•
Always keep the battery cables and terminals
clean and free of corrosion.
•
Avoid tipping. Even a sealed battery will leak
electrolyte when tipped.
LUBRICATION
BATTERY STORAGE
•
When storing the tractor for extended periods,
disconnect the negative battery cable. It is not
necessary to remove the battery.
•
All batteries discharge during storage. Keep the
exterior of the battery clean, especially the top. A
dirty battery will discharge more rapidly.
•
The battery must be stored with a full charge. A
discharged battery can freeze sooner than a
charged battery. A fully charged battery will store
longer in cold temperatures than hot.
•
•
Using a pressure lubricating gun, lubricate the
front castor axles and pivot axle with a No. 2
multi-purpose grease after every 10 hours of
service.
•
Refer to the "MOWER DECK" section later in this
manual for deck lubrication procedures.
•
Periodically lubricate all other pivot points with a
quality lubricating oil.
TIRE MAINTENANCE
Check the tire air pressure after every 50 hours of
operation or weekly. Keep the tires inflated to the
recommended pressures. Improper inflation will
shorten the service life of a tire. See the tire side wall
for proper inflation pressures. Observe the following
guidelines:
Recharge the battery before returning to service.
Although the tractor may start, the engine charging
system may not fully recharge the battery.

•
Do not inflate a tire above the maximum pressure
shown on the sidewall of the tire.
•
Do not reinflate a tire that has been run flat or
seriously under inflated. Have a qualified tire
mechanic inspect and service the tire.
USING THE TRANSMISSION BYPASS RODS
TRACTOR CREEPING
If for any reason the tractor will not drive or you wish
to move the tractor, the two hydrostatic transmissions are equipped with bypass rod that will allow you
to manually move the tractor short distances.
Creeping is the slight forward or backward movement
of the tractor when the engine is running at high idle
and the drive control levers are opened out in the
neutral position.
If after operating the tractor for some time, it begins to
creep while in the neutral position, adjust the
transmission control rods as follows.
• Place the front of the tractor against an
immovable object (e.g. wall, post, etc.).
• Jack up the rear of the tractor so that both rear
wheels are approximately one inch of the ground.
• With the engine running at high idle and the drive
control levers opened out in the neutral position,
and the parking brake disengaged, check the rear
wheels for rotation.
• If only one wheel is rotating, locate the transmission control rod beneath the frame at the front of
the rear tire. If both wheels rotate, locate both
control rods. See Figure 24.
WARNING: Do not tow the tractor, even
with the bypass rod engaged. Serious
transmission damage will result from
doing so.
•
From just in front of the two rear tires, locate the
transmission bypass rods. See Figure 23.
