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.
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 coul d 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.

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 des igned to hold the
mower from moving and is not intended for use in stopping the mower while it is
in motion.

OPERATION INSTRUCTIONS
The safe and successful operation of the 4000 Series Models will depend upon the operator
having the correct knowledge of all controls used on the mower and making good judgements
about the terrain to be mowed.
NEVER allow anyone to operate the mower without complete, knowledge of all controls and their
functions.
Sound judgement by the owner will prevent accidents.
BEFORE OPERATING MOWER:
1. Read engine manufacturer's operating and maintenance instructions.
2. Discuss proper maintenance with your dealer.
3. Read and observe all safety instructions on your mower and in the manual.
4. Check engine oil.
5. Check gas cap to be sure it is in place.
6. Be sure parking brake is on.
7. Mower blade drive is off.
8. Know how to stop engine. (Turn key to off position)
STARTING INSTRUCTIONS:
L
1. Move throttle control to "Choke" position if engine is cold, full throttle if warm.
2. Insert ignition key and turn to "Start" position. When engine starts, release ignition key.
Key will return to "Run" position.
3. Move throttle from "Choke" to desired speed position.

Page 13
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 of 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 A Sharp Blade Throughout The Cutting Season. This is very important. Optimal mulching
performance cannot be obtained with a dull or nicked up blade.
6.
Keep The Underside Of The Mower Deck Clean. Remove all grass and dirt buildup 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:
Page 14
1.
Raise the height-of-cut setting on your mower.
2.
It may be necessary to cut your grass more frequently.
3.
Operate the mower at a slower ground speed.
4.
Overlap cutting swaths instead of cutting a full swath with each pass.
5.
Mow across the marginal areas a second time.
6.
CUT HIGH - MOW OFTEN!
s
OPERATION INSTRUCTIONS
MOWING WITH A GRASS CATCHER ATTACHMENT:
In order to achieve optimum performance when mowing with a grass catching attachment, p lease 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.
Use only the correct blade(s). 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.
Maintain Sharp Blade(s) Throughout The Cutting Season.
7.
Operate the mower at a slower ground speed than when mowing without a grass catching
attachment.
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 bags.
Page 15
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 on Page 28.
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 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 Unde rside 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 professional for assistance.

MOWER CUT QUALITY:
There are many variables that can effect the cut quality of any riding mower. Type and conditions
of grass, cut height setting, engine RPM and ground speed are some of the variables that interact
creating differences in cut quality. Examination of one or more of the above will generally produce
a quality cut.
The Troubleshooting Chart suggests practices and adjustments that may be helpful in improving
cut quality. Your Dixon ZTR dealer is also available to provide assistance to you.
