IMPORTANT - READ CAREFULLY
The Dixon ZTR mower is both easy and fun to operate.
However, any power mower must be operated properly to be
safe. It is not a toy or a recreational vehicle. Before you use
the mower, read this Operator’s Manual carefully. It contains
valuable information that is necessary for the safe operation
of the machine. Observe all safety rules and become
completely familiar with the controls.
The information contained in this manual applies to all Dixon
ZTR SpeedZTR™ mowers.
See your authorized Dixon dealer for warranty service, parts
and repairs or to answer questions you have about your new
Dixon ZTR.

WARNINGS
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.
WARNING
!Failure to observe the following instructions
could result in serious injury or death.

7
WARNINGS
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.
WARNING
!Failure to observe the following instructions
could result in serious injury or death.

8
WARNINGS
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 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!
WARNING
!Failure to observe the following instructions
could result in serious injury or death.

9
WARNINGS
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.

10
WARNINGS
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.

11
WARNINGS
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.

12
WARNINGS
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.

13
WARNINGS
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.
WARNING
!Failure to observe the following instructions
could result in serious injury or death.
