WARNING
Failure to observe the following safety instructions
could result in serious injury or death.
GENERAL OPERATION:
Read, understand, and follow all instructions in this
manual and on the mower before starting.
Only allow responsible adults, who are familiar with the
instructions, to operate the mower.
Clear the area of objects such as rocks, toys, wire, etc.,
which could be picked up and thrown by the blade.
Be sure the area is clear of other people before mowing.
Stop mower if anyone enters the area.
Be aware of the mower discharge direction and do not
point it at anyone. Mower blades can throw rocks or other
debris.
Do not operate the mower without either the entire grass
catcher or the deflector in place. This will decrease the
possibility of injury from objects being thrown by the
mower blades.
Never carry passengers. They may fall off and become
seriously injured or interfere with safe operation of the
mower.
Mowing in reverse is not recommended because it is
difficult to maintain a clear vision of the mowing path.
However, should it become necessary to back up,
remember to look down and behind before and while
backing.

WARNING
Failure to observe the following safety instructions
could result in serious injury or death.
GENERAL OPERATION (continued):
Never leave a running mower unattended. Always turn off
blades, set parking brake, stop engine and remove key
before dismounting.
Turn off blades when not mowing. Injury could occur from
contact with moving parts.
Under no circumstances should you place hands or feet
under the mower deck or in the chute while blades or
impeller are still running.
To avoid personal injury from accidental clutch engage-
ment, stop engine before removing grass catcher or
unclogging chute.
Mow only in daylight or good artificial light.
Do not operate the mower while under the influence of
alcohol or drugs.
Slow down before turning to reduce the risk of tip-over.
Watch for traffic when operating near or crossing road-
ways.
Use extra care when loading or unloading the mower into
a trailer or truck. Push, do not ride the mower when
loading and unloading.

WARNING
Failure to observe the following safety instructions
could result in serious injury or death.
GENERAL OPERATION (continued):
Protect your eyes.Always wear safety goggles or safety
glasses with side shields when operating mower.
Data indicates that operators, age 60 years and above,
are involved in a large percentage of riding mower-
related injuries. These operators should evaluate their
ability to operate the riding mower safely enough to
protect themselves and others from serious injury.
To protect against possible tip-over, follow the
manufacturer’s recommendation for wheel weights and
counterweights.
Maintain or replace safety & instruction labels as
needed.
The engine exhaust from this product contains chemicals known to the State of
California to cause cancer, birth defects or other reproductive harm.

WARNING
Failure to observe the following safety instructions
could result in serious injury or death.
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 feel uneasy
on a slope, do not mow it!
DO
Mow across the slope with your Dixon® ZTR® --
never up or down. This will decrease the risk of
tip-over.
Remove obstacles such as rocks, tree limbs, wires
and other foreign objects that can be thrown by
mower blades.
Watch for holes, ruts, roots and bumps. Uneven
terrain could overturn the mower. Tall grass can
hide such obstacles.
Use slow speed. Tires may lose traction on slopes
even though the brakes are functioning properly.
Avoid starting or stopping on a slope. If tires lose
traction, disengage the blades and proceed slowly
down the slope.

WARNING
Failure to observe the following safety instructions
could result in serious injury or death.
SLOPE OPERATION (continued):
DO (continued):
Keep all movement on the slopes slow and
gradual. Do not make sudden changes in speed
or direction.
Use extreme caution when operating the mower
with attachments to prevent tip-over or roll-over.
If front wheels lift off the ground, pull levers back to
stabilize the mower. Discontinue mowing the
slope!

WARNING
Failure to observe the following safety instructions
could result in serious injury or death.
SLOPE OPERATION (continued):
DO NOT
Do not turn on slopes unless necessary, and then,
turn slowly and gradually downhill, if possible. Rapid
uphill turns may cause tip-over.
Do not mow near drop-offs, ditches, or embank-
ments. 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 mower by putting your foot
on the ground.
Do not use grass catcher or other attachments on
steep slopes. The added weight may change the
stability of the mower thus creating the potential for
tip-over.

WARNING
Failure to observe the following safety instructions
could result in serious injury or death.
FIRE HAZARDS:
Use extra care when handling gasoline and other
fuels. They are flammable and vapors are explosive.
Store all fuel in approved containers specifically
designed for that purpose.
Allow engine to cool before refueling. Never remove
fuel cap or add fuel with engine running.
Do not smoke while refueling or operating the mower.
To reduce fire hazard, keep mower free of grass,
leaves and other debris build-up.
If gasoline is spilled, do not attempt to start the
engine. Move mower away from the area of the spill.
Do not create any source of ignition until gas vapors
have dissipated. Wipe up spilled fuel and dispose of
waste properly.
If fuel is spilled on clothing, change clothing immediately.
Before storing, allow mower to cool. Clean fuel and
oil spillage.
Never store the mower or fuel container inside a
building where there is an open flame.

WARNING
Failure to observe the following safety instructions
could result in serious injury or death.
FIRE HAZARDS (continued):
To prevent fire or explosion, keep sparks and open flames
away from battery.
Keep electrical connections clean and tight. Inspect them
often. Loose connections and corrosion increase fire risk.
Before disconnecting the negative ground cable, make sure
all switches are off. This decreases the chance of sparking
and fire.
Use care when backing to avoid pushing the grass
bags into the frame or “hot” exhaust muffler of the
engine. Fire could result.
To prevent fire and explosion caused by static electricity:
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.
When practical, remove fuel powered equipment from
the truck or trailer and refuel it on the ground. If this is
not possible, refuel such equipment on a trailer with a
portable container, rather than from a fuel dispenser
nozzle.
If a fuel dispenser nozzle must be used, 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.

Failure to observe the following safety instructions
could result in serious injury or death.
CHILDREN:
Tragic accidents can occur if the operator is not
alert to the presence of children.
Children are attracted to lawn mowers and the
mowing activity.
NEVER assume children will stay where they
were last seen.
Be alert to avoid accidents.
Keep children out of the mowing area and under the
watchful care of another responsible adult.
Be alert and turn mower off if a child enters the area.
Before and during backing look BEHIND and DOWN
for small children.
Never carry children. They may fall off and be seriously
injured or interfere with safe mower operation.
Never allow children to operate the mower.
Use extra care when approaching blind corners, shrubs,
trees, or other objects that may obscure vision.

bolts, and keep equipment in good condition.
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
unless otherwise specified.
Grass catcher components are subject to wear, damage
and deterioration which could expose moving parts or allow
objects to be thrown. Frequently check components.
Replace with original equipment parts when necessary.
Mower blades are sharp and can cut. Wrap blades or wear
gloves, and use extra caution when servicing them.
Batteries contain sulfuric acid. To prevent burns, avoid
contact with skin, eyes and clothing.

OPERATION INSTRUCTIONS
MOWING WITH A MULCHING ATTACHMENT:
Mulching or recycling the grass clippings requires a
totally different mowing approach than would be normal
when side discharging or bagging the grass. There
may be instances or conditions where it is not possible
to hide all the recycled or mulched clippings.
In order to achieve the best results, please read and
follow the mulching tips listed below:
1. Read and follow the installation instructions that are
included with your mulcher.
2. Set the engine speed control to the wide open or full
setting.
3. Place the mower deck cut height selector in either
the top or second notch. Never cut more than 3/4” to
1” off the grass at any one time. Attempting to cut
more grass will result in the deck plugging and cause
the engine to stall.
4. It may be necessary to cut the lawn twice to achieve
acceptable mulching performance especially on first
cuttings or if the lawn is heavily fertilized.
5. Do not attempt to cut grass when it is wet. Mulching
performance will be very poor in wet grass conditions.
6. Maintain sharp blades throughout the cutting season.
This is very important. Optimal mulching performance
cannot be obtained with a dull or nicked up blade.

OPERATION INSTRUCTIONS
MOWING WITH A MULCHING ATTACHMENT
(continued):
7. Keep the underside of the mower deck clean.
Remove all grass and dirt build-up from the
underside of the pan, the baffles and deflectors
after each use. Never, under any circumstances,
should you place hands or feet under the
mower deck or in the chute while blades or
impeller are still turning.
8. Alternate mower direction. This will evenlydisperse
the mulched grass clippings over the lawn for even
fertilization.
If the mulching quality of the mower does not seem
to be satisfactory, try one or more of the following
tips:
a. Raise the height-of-cut setting on your
mower.
b. It may be necessary to cut your grass
more frequently.
c. Operate the mower at a slower ground
speed.
d. Overlap cutting swaths instead of cutting
a full swath with each pass.
e. Mow across the marginal areas a second
time.
f. CUT HIGH - MOW OFTEN!

OPERATION INSTRUCTIONS
MOWING WITH A GRASS CATCHER
ATTACHMENT:
In order to achieve optimum performance when
mowing with a grass catching attachment, please
read and follow the tips listed below.
1. Read and follow the installation instructions that are
included with your grass catcher.
2. Set engine speed control to the wide open or full
setting.
3. Do not attempt to cut grass when it is wet. Wet
grass will clog both the underside of the deck and
the attachment chutes. Empty bags often to
prevent plugging.
4. If the grass is tall, place the mower deck cut height
selector in the top or second notch. “Initially” overlap
cutting swaths instead of a full swath with each
pass.
5. Keep the underside of the mower deck clean.
Frequent removal of dried grass and dirt will greatly
assist in bagging of the clippings. Never, under
any circumstances, should you place hands
or feet under the mower deck or in the chute
while blades or impeller are still turning.
6. Operate the mower at a slower ground speed than
when mowing without a grass catching attachment.

OPERATION INSTRUCTIONS
MOWING WITH A GRASS CATCHER
ATTACHMENT (continued):
7. Maintain sharp blades throughout the cutting
season. Some grass catching attachments require a
“high-lift” blade. See your dealer for advice on the
type of blade(s) needed for your mower.
8. Some mowing applications/use of grass catchers
may require that an additional weight kit be fitted to
the mower to counter the weight of grass in the bags.
Please consult with your dealer for more information
regarding installation and adding weight to the box.
Failure to observe the following instructions
may result in personal injury.
WARNING
•Watch for low hanging branches or other obstacles which might hit
the catcher top while turning or backing the mower.
•Use care when backing to avoid pushing the grass bags into the
frame or “hot” exhaust muffler of the engine. Fire could result.
•Disengage blade and stop engine prior to clearing grass from
either the discharge chute or grass catcher components.
•Do not operate the mower with the grass catching attachment
partially removed. Operator or bystanders could be injured by
thrown objects.
•Keep all attachment bolts tight.
•Important: Do Not leave clippings in the bags while the mower is
stored. Damp grass clippings are a fire hazard if left in the bag.

OPERATION INSTRUCTIONS
SIDE DISCHARGE OF THE CLIPPINGS:
In order to achieve optimum performance when side
discharging the grass clippings, please read and follow
the tips listed below. Additional information can be
found in the Troubleshooting guide.
CAUTION To avoid personal injury, be sure that the
deflector is properly installed on the
discharge chute.
1. Set engine speed control to the wide open or full
setting.
2. Do not attempt to cut grass when it is wet. Wet
grass will clog the underside of the deck and
discharge area.
3. If the grass is tall, place the mower deck cut height
lever in the top or second notch. “Initially” overlap
cutting swaths instead of a full swath with each pass.
Some applications may require a second cutting.
4. Keep the underside of the mower deck clean.
Frequent removal of dried grass and dirt will allow
the clippings to discharge correctly. Never, under
any circumstances, should you place hands or
feet under the mower deck or in the chute while
blades or impeller are still turning.
5. Maintain sharp blade(s) throughout the cutting
season.

OPERATION INSTRUCTIONS
GRASS HEIGHT & CUTTING SUGGESTIONS:
Do not attempt to cut grass when it is wet.
If the grass is tall, place the mower deck cut height
lever in the top or second notch. “Initially” overlap
cutting swaths instead of a full swath with each pass.
Some applications may require a second cutting.
Keep the underside of the mower deck clean.
Maintain sharp blades throughout the cutting season.
As a rule of thumb, never cut off more than 1/3 of the
total grass blade length. Correct mowing height can
reduce weeds and disease by 50% to 80%.
The following grass cut heights are based on adequate
moisture conditions and normal thatch build-up in a
healthy lawn. Some locations and applications may
require slightly different cut heights. If in doubt, consult
your local lawn professional for assistance.
