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 and 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 and behind before and while braking.  
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.  
Turn off blades when not mowing.

SAFETY  
GENERAL OPERATION (continued):  
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.

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 requires 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 attach  
ments. 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.

SAFETY  
SLOPE OPERATION (continued):  
DO (continued):  
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.

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 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, 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.

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  
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. To prevent fire or  
explosion keep sparks and open flames away from  
battery.  
Before disconnecting the negative (-) ground cable,  
make sure all switches are off.

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 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.

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. 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. Do Not Attempt To Cut Grass When It Is Wet.  
Mulching performance will be very poor under wet  
grass conditions.  
5. 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.

OPERATION INSTRUCTIONS  
MOWING WITH A MULCHING ATTACHMENT  
(continued):  
6. 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.  
7. 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.  
b.  
c.  
d.  
e.  
f.  
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!

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. 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 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. Keep The Underside Of The Mower Deck Clean.  
Frequent removal of dried grass and dirt will greatly  
assist in bagging of the clippings.  
5. Maintain Sharp Blade(s) 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.  
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. 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.

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 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.  
5. Maintain Sharp Blade(s) Throughout The  
Cutting Season.

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  
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.  
Grass Types  
Bermudagrass  
Bluegrass  
Buffalograss  
Ryegrass  
Tall Fescue  
Zoysiagrass  
Best Cut Heights  
1 - 2”  
2 - 3”  
11/2 -3”
