SAFETY
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
ba cking.
• 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.

SLOPE OPERATION:
SAFETY
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.
CHILDREN:
SAFETY
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 responsi ble 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 are*.
• 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.

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 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:
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!
CAUTION
OPERATION INSTRUCTIONS
MOWING WITH A GRASS CATCHER ATTACHMENT:
In order to achieve optimum performance when mowing with a grass catching attachment, please 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.
