part of the operator can result in injury. This lawn mower is capable of amputating
hands and feet or throwing objects. Failure to observe the following safety
instructions could result in serious injury or death.
SAFE OPERATION PRACTICES
5. Be sure the area is clear of other people before
mowing. Stop machine if anyone enters the area.
6. Never carry passengers.
7. Disengage the blades before shifting into reverse
and backing up. Always look down and behind
before and while backing.
8. Be aware of the mower and attachment discharge
direction and do not point it at anyone. Do not
operate the mower without either the entire grass
catcher or the chute guard in place.
9. Slow down before turning. Operate the machine
smoothly. Avoid erratic operation and excessive
speed.
10. Never leave a running machine unattended.
Always turn off the blades, place the transmission
in neutral, set the parking brake, stop the engine
and remove key before dismounting.
11. Turn off blades when not mowing.
12. Stop the engine and wait until the blades come to
a complete stop before (a) removing the grass
catcher or unclogging chute, or (b) making any
repairs, adjusting or removing any grass or debris.
3
13. Mow only in daylight or good artificial light.
14. Do not operate the machine while under the
influence of alcohol or drugs.
15. Watch for traffic when operating near or crossing
roadways.
16. Use extra care when loading or unloading the
machine into a trailer or truck. This unit should not
be driven up or down a ramp onto a trailer or truck
under power, because the unit could tip over
causing serious personal injury. The unit must be
pushed manually on a ramp to load or unload
properly.
17. Never make a cutting height adjustment while the
engine is running if the operator must dismount to
do so.
18. Wear sturdy, rough-soled work shoes and closefitting slacks and shirts. Do not wear loose fitting
clothes or jewelry. They can be caught in moving
parts. Never operate a unit in bare feet, sandals
or sneakers.
19. Check overhead clearance carefully before driving
under power lines, wires, bridges or low hanging
tree branches, before entering or leaving
buildings, or in any other situation where the
operator may be struck or pulled from the unit,
which could result in serious injury.
20. Disengage all attachment clutches, set the
parking brake in the on position, and put the lap
bars to the neutral or out position before
attempting to start the engine.
21. Your mower is designed to cut normal residential
grass of a height no more than 10”. Do not
attempt to mow through unusually tall, dry grass
(e.g. pasture) or piles of dry leaves. Debris may
build up on the mower deck or contact the engine
exhaust presenting a potential fire hazard.
22. Use only accessories approved for this machine
by White Outdoor. Read, understand and follow
all instructions provided with the approved
accessory.
II. SLOPE OPERATION
Slopes are a major factor related to loss of contro l 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 operat ing this
unit on a sloped or hilly area. If the slope is greater
than 15° as shown on the slope gauge, do not operate
this unit on that area or serious injury could result.
DO:
Mow across slopes, not up and down.
Remove obstacles such as rocks, limbs, etc.
Watch for holes, ruts or bumps . Uneven terrain could
overturn the machine. Tall grass can hide obstacles.
Use slow speed. Choose a low enough speed so that
you will not have to stop while on the slope.
Follow the manufacturer’s recommendations for coun-
terweights with attachments to improve stability.
Use extra care with grass catchers or other attach-
ments. These can change the stability of the machine.
Keep all movement on the slopes slow and gradual.
Do not make sudden changes in speed or direction.
Rapid acceleration or deceleration could cause the
front of the machine to lift and rapidly flip ove r backwards, which could cause serious injury.
Avoid starting or stopping on a slope. If the tires lose
traction, disengage the blades and proceed slowly
straight down the slope.
DO NOT:
Do not turn on slopes unless necessary; if mowing
slopes, turn slowly and gradually uphill, if possible.
Do not mow near drop-offs, ditches or emb ankme nts.
The mower could suddenly turn over if a wheel is over
the edge of a cliff or ditch, or if an edge caves in.
Do not mow on wet grass. Reduced traction could
cause sliding.
Do not try to stabilize the machine by putting your foot
on the ground.
Do not use the grass catcher on steep slopes.
III. CHILDREN
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.
1. Keep children out of the mowing area and in
watchful care of an adult other than the operator.
2. Be alert and turn the machine off if children enter
the area.
3. Before and when backing up, look behind and
down for small children.
4. Never carry children, even with the blades off.
They may fall off and be seriously injured or may
interfere with safe machine operation.
4
5. Never allow children under 14 years old to
operate the machine. Children 14 years and over
should only operate the machine under close
parental supervision and proper instruction.
6. Use extra care when approaching blind corners,
shrubs, trees or other objects that may obscure
your vision of a child or other hazard.
7. Remove the key when the machine is left
unattended to prevent unauthorized operation.
IV. SERVICE
1. Use extreme care in handling gasoline and other
fuels. They are extremely flammable and the
vapors are explosive.
a. Use only an approved container.
b. Never remove fuel cap or add fuel with the en-
gine running. Allow the engine to cool at least
two minutes before refueling.
c. Replace the fuel cap securely and wipe off any
spilled fuel before starting the engine as it may
cause a fire or explosion.
d. Extinguish all cigarettes, cigars, pipes and oth-
er sources of ignition.
e. Never refuel the machine indoors because fuel
vapors will accumulate in the area.
f. Never store the fuel container or machine
inside where there is an open flame or spark,
such as a gas hot water heater, space hea ter
or furnace.
2. Never run a machine inside a closed area.
3. To reduce fire hazard, keep the machine free of
grass, leaves or other debris build-up. Clean up
oil or fuel spillage. Allow the machine to cool at
least 5 minutes before storing.
4. Before cleaning, repairing or inspecting, make
certain the blade and all moving parts have
stopped. Disconnect the spark plug wire, and
keep the wire away from the spark plug to prevent
accidental starting.
5. Check the blade and engine mounting bolts at frequent intervals for proper tightness. Also visually
inspect blades for damage (e.g., excessive wear,
bent, cracked). Replace with blades which meet
original equipment specifications.
6. Keep all nuts, bolts and screws tight to be sure
the equipment is in safe working condition.
7. Never tamper with safety devices. Check their
proper operation regularly. Use all guards as
instructed in this manual.
8. After striking a foreign object, stop the engine,
remove the wire from the spark plug and
thoroughly inspect the mower for any damage.
Repair the damage before restarting and
operating the mower.
9. Grass catcher components are subject to wear,
damage and deterioration, which could expose
moving parts or allow objects to be thrown. For
your safety protection, frequently check the
components and replace with manufacturer’s
recommended parts when necessary.
10. Mower blades are sharp and can cut. Wrap the
blades or wear gloves, and use extra caution
when servicing blades.
11. Check the park brake operation frequently. Adjust
and service as required.
12. Muffler, engine and belt guards become hot
during operation and can cause a burn. Allow to
cool down before touching.
13. Do not change the engine governor settings or
overspeed the engine. Excessive engine speeds
are dangerous.
14. Observe proper disposal laws and regulations.
Improper disposal of fluids and materials can
harm the environment and the ecology.
a. Prior to disposal, contact your local
Environmental Protection Agency to
determine the proper method for disposing of
the waste. Recycling centers are established
to properly dispose of materials in an
environmentally safe fashion.
b. Use proper containers when draining fluids.
Do not use food or beverage containers that
may mislead someone into drinking from
them. Properly dispose of the containers immediately following the draining of fluids.
c. DO NOT pour oil or other fluids into the
ground, down a drain or into a stream, pond,
lake, or other body of water. Observe Environmental Protection Agency regulations when
disposing of oil, fuel, coolant, brake fluid, filters, batteries, tires and other harmful waste.
15. We do not recommend the use of a pressure
washer or garden hose to clean your unit. They
may cause damage to electrical components;
spindles; pulleys; bearings; or the engine. The
use of water will result in shortened life and
reduce serviceability.
WARNING - YOUR RESPONSIBILITY: Restrict the use of this power machine to persons who
read, understand and follow the warnings and instructions in this manual and on the machine.

• 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, mov e 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 or use extreme care if the
traction surface is unstable or 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.
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 gasoline with a pump
sticker octane rating of 85 or higher. Unleaded
gasoline is recommended because it leaves less
combustion chamber deposits.
Some fuels are gasoline blended with alcohols or
ethers. Excessive amounts of the these blends
can damage the fuel system or cause engine
performance problems. 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 mo tor
oil in the engine. However, you MUST check the
oil level before operating. The capacity of the
engine and oil filter is approximately 48 oz. (1.4
liters) for the model ZT17 and 64 oz. (1.9 liters).
for the model ZT22. Be careful not to overfill.
• Clean the air cleaner element if necessary. See
Engine Manual.
• Check the tire inflation pressures.
• Adjust the seat for operator’s maximum comfort,
visibility, and for maintaining complete control of
the tractor.
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.
Contact your authorized White Outdoor Dealer.
• The safety interlock system prevents the engine
from cranking or starting unless the RH and LH
drive control levers are moved fully outward in the
neutral position, the parking brake is engaged,
and the PTO is disengaged.
• To avoid sudden movement when disengaging
the parking brake, the safety interlock system will
shut off the engine if the RH and/or LH drive
control levers are moved to a position other than
the fully out in neutral position when the parking
brake is engaged
• The safety interlock system will shut off the
engine if the operator leaves the seat before
engaging the parking brake.
13
• The safety interlock system will shut off the
engine if the operator leaves the seat with the
PTO engaged, regardless of whether the parking
brake is engaged.
NOTE: The PTO switch must be moved to the
“OFF” position to restart the engine.
• The safety interlock system will shut off the PTO
and the mower blades will stop if both driv e control levers are moved into the reverse position.
The PTO will re-engage when one or both of the
levers are moved back to the neutral or forward
position.
STARTING THE ENGINE
WARNING: For personal safety, the
operator must be sitting in the tractor
seat when starting the engine.
WARNING: This unit is equipped with a
safety interlock system designed for the
protection of the operator. Do not operate the tractor if any part of the interlock
system is malfunctioning. Periodically
check the functions of th e interlock system for proper operation.
• Move the RH and LH drive control levers fully
outward in the neutral position. Refer to Figure 8.
• Operator must be sitting in the tractor seat.
• Engage the parking brake. Refer to Figure 8.
• Make certain the PTO switch is in the disengaged (down) position. Refer to Figure 8.
• Model ZT17 ONLY
1. Move the throttle control lever fully forward
into the "CHOKE" position. NOTE: If the
engine is warmed up, it may not be ne cessary
to place the throttle control in the choke
position.
2. Turn the ignition key clockwise to the “START”
position and release it as soon as the engine
starts; however, do not crank the engine
continuously for more than 5 seconds at a
time. If the engine does not start within this
time, turn the key to “OFF” a nd wait a minute
to allow the engine’s starter motor to cool. Try
again after waiting. If after a few at tempts the
engine fails to start, do not k eep trying to start
it with the choke closed as this will cause
flooding and make starting more difficult.
3. As the engine warms up, gradually pull the
throttle control lever rearward past the choke
detent position. Do not use the choke to enrich
the fuel mixture, except as nec essary to start
the engine.

COLD WEATHER STARTING
Be sure to use the proper oil for the expected
temperatures (check the table in the engine manual).
Follow the normal engine starting instructions above.
However, allow the engine ample time to warm up
before putting the tractor under load.
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.
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.
• 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.
• Have the tractor’s electrical system checked and
repaired as soon as possible to eliminate the
need for jump starting.
STOPPING THE ENGINE
• Place the PTO switch in the “OFF” position.
• Engage the parking brake.
• Move the RH and LH drive control levers fully
outward in the neutral position.
• Model ZT17 ONLY — Place the throttle control
lever to the fast (high idle) position.
• Model ZT22 ONLY — Place the throttle control
lever to the slow (idle) position.
• Turn the ignition key to the “OFF” position and
remove the key from the ignition switch.
NOTE:
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.
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.
Carefully move (or have moved) the tractor to the
practice area. When performing the practice session,
it not necessary operate with the PTO engaged.
While practicing, operate the tractor at approximately
1/2 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
• Adjust the operator’s seat to the most
• Release the parking brake.
Always remove the key from the ignition
WARNING: Avoid sudden starts, excessive speed and sudden stops.
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.

• Move the throttle control lever forward to the full
throttle position (3500-3600 RPM).
IMPORTANT: The tractor and engine are designed to
run at full throttle. However, if performing a prac-
tice session, the tractor should be operated at
half throttle (approximately 2500-2600 RPM). This
only applies to practice operation.
NOTE: For Model ZT17, make certain the throttle
control has not been moved t oo far forward into the
"Choke" position.
• 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.
Driving the Tractor Forward
WARNING: Keep all movement of the
drive control levers slow and smooth.
Abrubt movement of the control levers
can affect the stability of the tractor and
could cause the tractor to flip over,
which may result in serious injury or
death to the operator.
• Slowly and evenly move both drive control levers
forward. The tractor will start to move forward.
See Figure 10.
• As the control levers are pushed farther forward
the speed of the tractor will increase.
• 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 .
IMPORTANT: Always maintain your grasp on the
drive control levers. Do not release the levers to
slow the tractor or to return to neutral.
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.
• 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.
