SAFETY
This cutting mower is capable of amputating hands & 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.
• Nevercarrypassengers.
• 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.
WARNING:
Page 6
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.
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.
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 7
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.
Page 8
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. 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 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.

Page 19
OPERATIONINSTRUCTIONS
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.
2.
Set the engine speed control to the wide open or full setting.
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.
4.
5.
6.
7.
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.
Do Not Attempt To Cut Grass When It Is Wet. Mulching performance will be very poor under
wet grass conditions.
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.
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.
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.
2.
3.
4.
5.
6.
Raise the height-of-cut setting on your mower.
It may be necessary to cut your grass more frequently.
Operate the mower at a slower ground speed.
Overlap cutting swaths instead of cutting a full swath with each pass.
Mow across the marginal areas a second time.
CUT HIGH - MOW OFTEN!
Page 20
OPERATIONINSTRUCTIONS
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.
Some applications may require installation of an "Optional" weight box on the front of the mower
to offset cut grass weight.
2.
3.
Set engine speed control to the wide open or full setting.
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.
4.
5.
6.
7.
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.
Keep The Underside Of The Mower Deck Clean. Frequent removal of dried grass and dirt will
greatly assist in bagging of the clippings.
Maintain Sharp Blades Throughout The Cutting Season. Some grass catching attachments
require "Hi-Lift" blades.
Operate the mower at a slower ground speed than when mowing without a grass catching
attachment.
CAUTION
•
•
•
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 21
OPERATIONINSTRUCTIONS
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.
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 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 Underside Of The Mower Deck Clean. Frequent removal of dried grass and dirt will
allow the clippings to discharge correctly.
5. Maintain Sharp Blades 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.
