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.
WARNING
!Failure to observe the following instructions
could result in serious injury or death.
WARNING
7
GENERAL OPERATION (continued):
Never leave a running mower unattended. Always turn
off blades, set Park Brake, stop engine and remove key
before dismounting.
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.
WARNING
!Failure to observe the following instructions
could result in serious injury or death.
WARNING
8
GENERAL OPERATION (continued):
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.
The engine exhaust from this product contains chemicals
known to the State of California to cause cancer, birth de-
fects or other reproductive harm.
WARNING
!Failure to observe the following instructions
could result in serious injury or death.
WARNING
9
SLOPE OPERATION:
Slopes are a major factor related to loss-of-con-
trol 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.
WARNING
!Failure to observe the following instructions
could result in serious injury or death.
WARNING
10
SLOPE OPERATION (continued):
DO
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 instructions
could result in serious injury or death.
WARNING
11
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.
WARNING
!Failure to observe the following instructions
could result in serious injury or death.
WARNING
12
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.
WARNING
!Failure to observe the following instructions
could result in serious injury or death.
WARNING
13
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.
WARNING
!Failure to observe the following instructions
could result in serious injury or death.
WARNING
14
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.
WARNING
!Failure to observe the following instructions
could result in serious injury or death.
WARNING
15

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
26
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.
OPERATION INSTRUCTIONS
27
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
28
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
29
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.
• 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.
WARNING
!Failure to observe the following instructions
could result in personal injury.
OPERATION INSTRUCTIONS
30
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.
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.
CAUTION
!To avoid personal injury, be sure that the
deflector is properly installed on the
discharge chute.
OPERATION INSTRUCTIONS
31
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 11/2 -3"(38-76 mm)
Ryegrass 2 - 3" (51-76 mm)
Tall Fescue 3-31/2" (76-89 mm)
Zoysiagrass 1 - 3" (25-76 mm)
