WARNING
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.
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., that 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.
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.
The engine exhaust from this product contains chemicals
known to the State of California to cause cancer, birth
defects or other reproductive harm.

WARNING
WARNING
!
Failure to observe the following instructions
could result in serious injury or death.
GENERAL OPERATION (continued)
To avoid personal injury from accidental clutch engagement, 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 roadways.
Use extra care when loading or unloading the mower into a trailer
or truck. Push, do not ride the mower when loading and unloading.
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 and instruction labels as needed.

WARNING
Failure to observe the following instructions
could result in serious injury or death.
SLOPE OPERATION
Slopes are a major factor related to loss-of-control and tipover 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 up and down the slope with your Dixon ZTR — never across.
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!

WARNING
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 tipover.
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, creating
the potential for tip-over.

WARNING
WARNING
!
Failure to observe the following instructions
could result in serious injury or death.
ROLL OVER PROTECTION SYSTEM (ROPS)
The ROPS increases the basic weight of the unit by 42 Ibs/19 kg.
The ROPS on the US units are standard, on the European unit the
ROP is an accessory.
The ROP’s capability may be impaired by structural damage if
overtumed or alterations are made. Do not make changes to the
structure and if any damage occurs, replace the entire ROPS unit.
• Do not use ROPS as a lifting, attaching or anchoring point.
• Do not use ROPS for wrecking or towing.
• Do not exceed maximum gross vehicle weight of 2822 Ibs.
(1283 kg).
• Securely fasten your seat belt if the unit has a ROPS.
• Where possible, avoid operating the mower near ditches,
embankments or holes.
• Reduce speed when turning, crossing slopes and on rough,
slick or muddy surfaces.
• Stay off slopes too steep for safe operation.
• Watch where you are going, especially at row ends, on roads
and around trees.
• Do not permit others to ride.
12
Page 13
WARNING
ROLL OVER PROTECTION SYSTEM (ROPS)
(continued)
• Operate the mower smoothly - no jerky turns, starts or stops.
• When mower is stopped, set brakes securely and use park
brake.
• If any part of ROPS is damaged, the entire ROPS must be
replaced.
• Check all bolts, including seat belt, for correct torque before
each use.
• Check ROPS structure for damage before each use.
• ROPS bar is NOT intended for use in sub zero temperatures.
Owner/operator responsibilities
• Read and observe the safety rules.
• Follow a regular schedule in maintaining, caring for and using
your mower.
• Follow the instructions under “Maintenance” and “Storage”
sections of this owner’s manual.

WARNING
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.
14
Page 15
WARNING
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.

WARNING
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.

WARNING
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.

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.

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.
• Cut 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.
34

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 or 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.
9. Ensure mower is equipped with an approved, dealer-installed
roll-over protection and seat belt kit.
WARNING
!
Failure to observe the following instructions
could result in serious injury or death.
• Watch for low hanging branches or other obstacles that 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
!
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, place your
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)

CARE AND MAINTENANCE
MOWER DECK LEVELING PROCEDURE
There are four (4) eyebolts that will control the attitude or pitch of
the mower deck. The deck should be level or pitched slightly
higher in rear.
1. Place the mower on a smooth level surface with front casters
positioned towards deck. Check tire pressures to insure the
mower has a correct stance. Inflate tires as required:
Front 15 lbs (103 kPa)
Rear: 15 lbs (103 kPa)
NOTE: To insure accuracy of leveling procedure, mower deck
drive belt must be installed prior to leveling deck.
2. Wear heavy gloves. Turn each outer blade tip to align with the
deck or in a side-to-side manner.
3. Measure from the floor surface up to the bottom of the blade tip
on the discharge side of the mower. Retain this measurement.
Move to the opposite side and check to see if that
measurement is the same. If adjustment is required, turn nut
on one or both of the front eyebolts until both measurements
are equal.
4. Turn each outer blade tip to align with the deck in a front to
rear manner.
5. Measure from the floor surface up to the bottom of the blade
tips at both the front and rear of the blades. Rear of blade tips
should be 1/8" to ¼" higher than the front of blade tips. If
adjustment is required, turn nut on one or both of the rear
eyebolts until both measurements are equal.
NOTE: This will place the mower deck in a base measurement
position. Additional adjustment may be required to
achieve desired cut for the type of grass or conditions
involved.

CARE AND MAINTENANCE
ELECTRICAL SYSTEMS
Keep all connections clean and tight.
CLEANING THE MOWER
Wash mower periodically. Clean above and below deck.
High pressure washing and alkaline based soaps can cause
damage to bearings and other parts of the mower. After washing
your mower, start the engine and engage the mower deck for a few
minutes to disperse any water that may have accumulated in
bearings, pulleys or fans.
Note: Allow mower to cool before washing. If bearings are hot,
they will draw moisture inside as they dry and cause
corrosion.
