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 engage-  
ment, 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 road-  
ways.  
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):  
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 & 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  
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 embank-  
ments. 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.

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 evenlydisperse  
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.  
Failure to observe the following instructions  
may 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.  
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.

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.

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.  
4. Using a slight upward twisting motion, remove link from  
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.
