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.

6

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 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.

7

WARNING

Failure to observe the following safety instructions

could result in serious injury or death.

GENERAL OPERATION (continued):

Never dismount mower without applying parking brake

or stopping engine.

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 mower­related 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.

8

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.

9

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!

10

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 embank­ments. 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.

11

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.

12

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.

13

WARNING

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.

14

WARNING

Failure to observe the following safety 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 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.

25

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.

26

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 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:

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!

27

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. Fre-

quent 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.

28

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: Do Not leave clippings in the bags while the mower is

stored. Damp grass clippings are a fire hazard if left in the bag.

Failure to observe the following instructions
may result in personal injury.

29

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.

30

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.

Grass Types Best Cut Heights
Bermudagrass 1 - 2”
Bluegrass 2 - 3”
Buffalograss 1

1/2

-3”
Ryegrass 2 - 3”
Tall Fescue 3-3

CARE AND MAINTENANCE

MOWER DECK LEVELING PROCEDURE:

1. Place mower on a smooth, level surface and check
tire pressures to insure correct stance. Tires should
be inflated as follows.

Front: 16 - 21 lbs
Rear: 8 - 14 lbs

2. Turn blade so tips align with the deck 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
rear L-rods until both measurements are equal.

4. Turn blade so tips align with the deck in a front to
rear manner.

5. Measure from the floor surface up to the bottom of
the blade tip at both the front and rear of the blade.
Rear blade tip should be 1/8" to 1/4" higher than the
front blade tip. If adjustment is necessary, turn nut on
front L-rod.

(See Illustration B, page 40)

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.

41

CARE AND MAINTENANCE

DECK REMOVAL:

1. Place cut height lever in lowest cut position.

2. Loosen belt keepers.

3. Remove deck drive belt from engine pulley.

engagement handle.

5. Turn handle fully to the left until handle clears stop on

mower deck pan. Lift handle then remove handle down
through hole in lower fender.

6. Remove hair pin cotter and washer from one end of deck

support cross shaft. Note location of remaining shim
washers used between chassis and mower deck pan
arms. Slide shaft from chassis and mower deck.

7. Remove hair pin cotter and washer from each deck

adjustment rod. Carefully push each link to disengage
from deck lift arms. At this point, deck will drop down.

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.

The serial number is located on frame at rear of engine.

WARRANTY:

Refer to warranty information (page 16).

PARTS/SERVICE:
