become completely familiar with the controls.
The information in this operator's manual applies to all
Dixon®ZTR®Series Mowers.
Your Dixon dealer will gladly provide a check-out ride,

This cutting mower is capable of amputating hands and feet, and throwing objects.
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. 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.
The Engine Exhaust from this product contains chemicals known to the
State of California to cause cancer, birth defects or other reproductive harm.

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.
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.
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.
Page 5

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.
Page 6

SERVICE:
•DRINK/CUP HOLDER located on left rear fender is for transporting or carrying ONLY! Mower
usage requires that both hands be free to control individual levers. DO NOT attempt
operation of mower with any type of container or other object in either hand.
•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.
•Never run a mower inside a closed area.
•Keep nuts and bolts, especially blade attachment bolts, tight 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 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.
•Check to assure that the drive chains are properly adjusted. A loose chain may come off
causing loss of control. This statement applies to chain drive models 2301, 3000 & 4000
Series. .......
