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.
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.
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.
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.

CONTROLS
The Dixon ZTR has a unique transaxle that requires only two drive levers to control braking,
turning, speed, and direction.
On initial operation, set throttle speed on slow and operate with mower blade "OFF". To
avoid "over-controlling" the mower, use a light touch on the drive levers. Slight
movements using fingertip control is all that is necessary.
All controls are described from operators, position:
PARKING BRAKE:
The parking brake used on the 4000 Series Models is designed to hold the
mower from moving and is not intended for use in stopping the mower while
it is in motion.
CAUTION Engage parking brake before starting engine.
Do not leave engine running for extended periods of time without the
parking brake engaged. Damage to the drive system could result.
TO SET PARKING BRAKE:
The hand operated parking brake is located at left hand side of Model ZTR
4421 and on the right hand side of Models ZTR 4423 and ZTR 4424.
To engage brake, pull lever up and to the rear. To release brake, move
lever forward and down. NOTE: Always set parking brake before
dismounting. Release parking brake before moving mower.
TRANSMISSION DRIVE SYSTEM:
Allows the mower to turn on its own axis (zero turning radius).
Each lever controls one side of the mower.
NOTE: The pressure required to operate the mower is very light.
A minimum of 1/2 hour should be spent simply driving the mower
without the-blade drive engaged.
Page 13

TO GO FORWARD:
From neutral position, gently push both drive levers forward. To
increase speed, move levers farther forward.
TO GO BACKWARD:
From neutral position, gently pull both drive levers toward you.
TURNING:
Turning is controlled by moving one drive lever slightly forward or rearward of the other.
To turn left, move left lever rearward of the right lever. »,
To turn "square corners" move lever of desired direction to neutral.
To turn on mower's own axis (zero turning radius) stop and move one lever to reverse
position and the other to forward position.
BRAKING:
To brake mower, move both levers in direction opposite of travel, release levers to
neutral, set parking brake. Park only on level surfaces.
TWIN FUNCTION THROTTLE CONTROL LEVER:
Located on control panel to operators right.
Throttle control for engine speed.
Choking for engine starting.
Throttle C9ntrol should be set to the MAXIMUM or wide open setting to insure adequate
cooling of the engine and to maintain mower deck blade speed while mowing.

amp circuit breaker.
If circuit breaker trips, push button to reset.
If this condition repeats, consult dealer for
inspection and repair.
