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

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

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

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

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

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

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

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

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  
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  
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.

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.

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

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 on Page 44-45.  
To avoid personal injury, be sure that the  
deflector is properly installed on the  
discharge chute.  
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,  
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.

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.

Bluegrass  
Buffalograss  
Ryegrass
