Failuretoobservethefollowingsafetyinstructionscouldresultin  
seriousinjuryor 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. Always turn off blades, set parking brake, stop engine,  
and remove key before dismounting.  
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 & 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 or counterweights.  
Maintain or replace safety and instruction labels, as necessary.

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.  
Useextracarewith grasscatchersor other attachments. Thesecan changethestabilityofthemower.  
Keepallmovement ontheslopesslowandgradual. Donot makesuddenchangesinspeedordirection.  
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.  
Donot mowneardrop-offs,ditches,orembankments. Themowercouldsuddenlyturn overifawheel  
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  
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 watch-  
ful 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.

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 gas cap or add fuel with the engine running. Allow  
engine to cool before refueling. Do not smoke.  
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 immediatley.  
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 gas-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 gasoline dispenser nozzle.  
If a gasoline 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.  
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.  
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 equip-  
ment parts, when necessary.

OPERATION INSTRUCTIONS  
In order to achieve optimum cutting performance, please read and follow the  
tips listed below.  
Additional information can be found in the troubleshooting guide beginning on  
page 35.  
CAUTION  
Be sure that 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 under-  
side of the deck and discharge area.  
3. If the grass is tall, place the mower deck cut height lever in the top or sec-  
ond 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.  
GRASS HEIGHT SUGGESTIONS:  
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 pro-  
fessional for assistance.
