WARNINGS
WARNING
!
Failure to observe the following 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.
In this operator’s manual, left and right, backward and
forward are used in relation to the machine’s normal driving
direction.
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 bystanders before mowing. Stop
mower if anyone enters the area.
Never direct discharged material toward anyone. Avoid
discharging against a wall or obstruction. Material may
ricochet back toward the operator. Stop the blade(s) when
crossing gravel surfaces.
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.
Do not mow in reverse unless absolutely necessary. Always
look down and behind before and while backing.
Never leave a running mower unattended. Always turn off
blades, set Park Brake, stop engine and remove key before
dismounting.

WARNINGS
WARNING
!
Failure to observe the following instructions
could result in serious injury or death.
GENERAL OPERATION (continued)
Do not put hands or feet near rotating parts or under the
machine. Keep clear of the discharge opening at all times.
Disengage blade(s) when not mowing. Shut off engine and
wait for all parts to come to a complete stop before cleaning
the machine, removing the grass catcher, or unclogging the
discharge guard.
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 roadways.
Use extra care when loading or unloading the mower into a
trailer or truck.
Always wear eye protection when operating machine.
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.
Follow the manufacturer’s recommendation for wheel weights
and counterweights.

WARNINGS
WARNING
!
Failure to observe the following instructions
could result in serious injury or death.
SLOPE OPERATION
Slopes are a major factor related to loss-ofcontrol and tip-over accidents, which can result in
severe injury or death.
All slopes require extra caution. If you feel unsure
on any 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 and uneven terrain
that 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.
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!
8
WARNINGS
WARNING
!
Failure to observe the following 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 embankments.
Unstable ground may cause loss of control.
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.

WARNINGS
WARNING
!
Failure to observe the following 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 buildup.
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.
10
WARNINGS
WARNING
!
Failure to observe the following 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.
11
WARNINGS
WARNING
!
Failure to observe the following instructions
could result in serious injury or death.
CHILDREN, BYSTANDERS AND PETS
Tragic accidents can occur if the operator is not alert
to the presence of children, bystanders and pets.
Children are attracted to lawn mowers
and the mowing activity.
NEVER assume children, bystanders and pets
will stay where they were last seen.
Be alert to avoid accidents.
Keep bystanders and pets out of the mowing area and keep
children under the watchful care of another responsible adult.
Be alert and turn mower off if bystanders, children or pets
enter the area.
Before and during backing look BEHIND and DOWN for
small children.
Never carry children as passengers. 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.

WARNINGS
WARNING
!
Failure to observe the following instructions
could result in serious injury or death.
SERVICE
Never run a mower inside a closed area or without proper
ventilation.
Keep nuts and bolts tight, especially blade attachment 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 that could expose moving parts or allow objects
to be thrown. Frequently check components. Replace with
original equipment parts when necessary.
When servicing blades, wrap blades or wear gloves, and use
extra caution.
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
¾" (19 mm) to 1" (25mm) 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 blade.
28
OPERATION INSTRUCTIONS
MOWING WITH A MULCHING ATTACHMENT
(continued)
7. Keep the underside of the mower deck clean. Remove
all grass and dirt buildup 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 evenly disperse 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:
• Raise the height-of-cut setting on your mower.
• It may be necessary to cut your grass more frequently.
• Operate the mower at a slower ground speed.
• Overlap cutting swaths instead of cutting a full swath with
each pass.
• Mow across the marginal areas a second time.
• 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.
30
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.
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:
mower is stored. Damp grass clippings are a fire hazard if
left in the bag.
Do not leave clippings in the bags while the
Failure to observe the following instructions
could result in personal injury.
31
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 on Page 44-45.
CAUTION
!
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.
To avoid personal injury, be sure that the
deflector is properly installed on the
discharge chute.

OPERATION INSTRUCTIONS
GRASS HEIGHT AND 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 one third 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 buildup in a healthy
lawn. Some locations and applications may require slightly
different cut heights. If in doubt, consult your local lawn
professional for assistance.
Grass Types Best Cut Heights
Bermudagrass 1 - 2" (25-51 mm)
Bluegrass 2 - 3" (51-76 mm)
Buffalograss 1½ -3" (38-76 mm)
Ryegrass 2 - 3" (51-76 mm)
Tall Fescue 3-3½" (76-89 mm)
Zoysiagrass 1 - 3" (25-76 mm)
