SAFETY
Failure to observe the following safety
instructions could result in serious injury or death.
GENERAL OPERATION:
•Read, understand, and follow all instructions in the
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 & thrown by the blade.
•Be sure the area is clear of other people before
mowing. Stop mower if anyone enters the area.
•NEVER carry passengers.
•Do not mow in reverse unless absolutely necessary.
Always look down & behind before & while backing.
•Be aware of the mower discharge direction and do
not point it at anyone.
•Do not operate the mower without either the entire
grass catcher or the deflector in place.
•Slow down before turning.
•Never leave a running mower unattended. Always
turn off blades, set parking brake, stop engine and
remove key before dismounting.
6
SAFETY
GENERAL OPERATION (continued):
•Turn off blades when not mowing.
•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.
•Watch for traffic when operating near or
crossing roadways.
•Use extra care when loading or unloading the
mower into a trailer or truck. Do not ride the
mower when loading and unloading.
•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.
•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.
WARNING:
7
SAFETY
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 cannot back up the slope or if you feel uneasy on it,
do not mow it!
DO
•Mow across the slope with your Dixon ZTR - never up or down.
•Remove obstacles such as rocks, tree limbs, etc.
•Watch for holes, ruts or bumps. Uneven terrain could overturn
the mower. Tall grass can hide obstacles.
•Use slow speed. Tires may lose traction on slopes even though
the brakes are functioning properly.
•Use extra care with grass catchers or other attachments. These
can change the stability of the mower.
•Keep all movement on the slopes slow and gradual. Do not
make sudden changes in speed or direction.
•Avoid starting or stopping on a slope. If tires lose traction,
disengage the blades and proceed slowly down the slope.
•If front wheels lift off the ground, pull the levers back to stabilize
the mower.
DO NOT
•Do not turn on slopes unless necessary, and then, turn slowly
and gradually downhill, if possible.
•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 on steep slopes.
8
SAFETY
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 seri-
ously 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.
9
SAFETY
SERVICE:
•Use extra care in handling gasoline and other fuels.
They are flammable and vapors are explosive.
Use only an approved container.
Never remove fuel cap or add fuel with engine
running. Allow engine to cool before refueling.
Do not smoke while refueling.
Never refuel the mower indoors.
Never store the mower or fuel container inside
a building where there is an open flame.
If fuel is spilled on clothing, change clothing
immediately.
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, then 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.
10
SAFETY
SERVICE (continued):
•Never run a mower inside a closed area. The exhaust
fumes are toxic.
•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.
•Keep mower free of grass, leaves, or other debris build-
up. Clean up oil or fuel spillage. Allow mower to cool
before storing.
•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 compo-
nents and replace with original equipment parts, when
necessary.
•Mower blades are sharp and can cut. Wrap the blade(s)
or wear gloves, and use extra caution when servicing
them.
•Batteries contain sulfuric acid. To prevent burns avoid
contact with skin, eyes and clothing. To prevent a fire
or explosion keep sparks and open flames away from
battery.
•Before disconnecting the negative (-) ground cable,
make sure all switches are OFF.

CAUTION
Be sure that the deflector is properly
installed on the discharge chute.
1,
2.
Set engine speed control to the wide open or full
setting.
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.
5.
Maintain Sharp Blade(s) Throughout The Cutting
Season.
22
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 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.

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 of the recycled or mulched clippings.
In order to achieve the best results, please read and follow the
mulching tips listed below:
1.
Set the engine speed control to the wide open
or full setting.
2.
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.
3.
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.
4.
5.
Do Not Attempt To Cut Grass When It Is Wet.
Mulching performance will be very poor under
wet grass conditions.
Maintain Sharp Blade(s) Throughout The Cutting
Season. This is very important. Optimal mulching
performance cannot be obtained with a dull or
nicked-up blade.
24
OPERATION INSTRUCTIONS
MOWING WITH A MULCHING ATTACHMENT
(continued):
6.
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.
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 satis-
factory, try one or more of the following tips:
1.
2.
3.
4.
5.
6.
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!
25
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.
2.
Set engine speed control to the wide open or full
setting and engage mower before entering area
to be cut.
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.
3.
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.
4.
5.
Keep The Underside Of The Mower Deck Clean.
Frequent removal of dried grass and dirt will
greatly assist in bagging of the clippings.
Use only the correct blade(s). Some grass
catching attachments require a “high-lift” blade.
See your dealer for advice on the type of blade(s)
needed for your mower.
6.
Maintain Sharp Blade(s) Throughout The Cutting
Season.
26
OPERATION INSTRUCTIONS
MOWING WITH A GRASS CATCHER ATTACHMENT
(continued):
7.
8.
Operate the mower at a slower ground speed than
when mowing without a grass catching attachment.
Some mowing applications/use of grass catchers
may require that an optional weight box 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.
CAUTION
•
•
•
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.
Disengage blade and stop engine prior to clearing
grass from either the discharge chute or grass
catcher components.
•
•
Keep all attachment bolts tight.
Do Not operate the mower with the grass catching
attachment partially removed.
•
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.

CARE AND MAINTENANCE
DRIVE SYSTEM ADJUSTMENTS:
Due to both the complex nature of the transmission
and the number of special tools required for service,
adjustments should be entrusted to your dealer.
There are a number of simple owner service items
which greatly influence the performance of the drive
system.
1. Front and rear tires must be inflated to proper
specifications.
2. Rear drive chain tension.
3, Tightness of all controls and linkages pertaining
to the drive levers.
4. Lubrication of both primary and final drive chains.
The use of a high quality chain lubricant is highly
recommended.
36
CARE AND MAINTENANCE
REAR CHAIN ADJUSTMENT:
Proper tension for the rear chains is accomplished
through the use of an “automatic” adjuster located
at mid-point of each rear chain.
Maintenance:
Periodically remove any build-up of grass, mud or
other debris from both the spring loaded roller and
the upper guide rod. The use of a penetrating
lubricant on the springs and rod is recommended
as a rust preventative.
37
CARE AND MAINTENANCE
LUBRICATION:
CHASSIS:
(5) grease zerks
LOCATIONS:
(1) each front wheel caster
(1) each mower deck hub
SERVICE INTERVALS:
Every 50 hours of operation
RECOMMENDED GREASE: Name brand wheel bearing or
multi-purpose grease. Once
per season or 50 hours of
operation (3 pumps each)
Note: Lubrication of the mower deck hubs will help dispel moisture
within the hub casting. Bearings are of a sealed variety.
PLEASE DISPOSE OF USED OILS AT PROPER COLLECTION CENTERS.
PROTECT YOUR ENVIRONMENT.
38
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 & cause corrosion.
MOWER DECK PLATES:
Check periodically. Replace bolted-on wear plates before shaft
wears into mower deck plates. See illustration.
SERIAL NUMBERS:
The serial number is located on frame at rear of engine.
WARRANTY:
See Warranty Registration Form(sample on page 12).
PARTS/SERVICE:
See your Dixon dealer for replacement parts, warranty or service.
PLEASE HELP PROTECT THE ENVIRONMENT BY AVOIDING ALL
CHEMCIALS WHICH MAY DAMAGE OR CAUSE HARM TO
PLANTS AND ANIMALS IN YOUR AREA.
