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 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 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. Alwaysturn 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 crossingroadways.  
•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.  
WARNING:  
The engine exhaust from this product contains chemicals known to the State of  
California to cause cancer, birth defects or other reproductive harm.  
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 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.  
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 buildup. 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 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.

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 an 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.

CARE AND MAINTENANCE  
CHECKING & REPLENISHING OIL IN HYDROSTATIC  
TRANSMISSION:  
Dirt or water in oil can ruin the  
hydrostatic transmissions.  
Check the oil level in hydrostatic transmission oil  
reservoir after every 25 hours of usage. Clean the  
oil reservoir cap and the area around it prior to  
removal. Check the oil level. Oil should be  
approximately 1-3/8” below top of oil tank. Replenish  
as needed with SAE 20W-50 motor oil. DO NOT  
OVERFILL. When checking the oil level, be very  
careful to keep the reservoir clean.  
Change the oil in the reservoir and hydrostat  
transmission oil filter after the first 100 hours of use.  
Then every 500 hours after that. Remove the filter  
and be sure all oil has drained from the reservoir.  
Replace with new filter and SAE 20W-50 motor oil.  
Please dispose of used oil at proper collection centers -  
protect your environment
