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.
• Always wear safety goggles or safty glasses with side shields when operating mower.
• Data indicates that operators, age 60 years and above, are involved in a large percentage of riding mower-related
injuries. These operators should evaluate their ability to operate the riding mower safely enough to protect
themselves and others from serious injury.
• Follow the manufacturer's recommendation for wheel weights or counterweights.

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.
SAFETY
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.
Useslow speed. Tiresmay losetraction onslopes eventhough thebrakes arefunctioning properly.
Useextracarewithgrasscatchersorotherattachments. Thesecanchangethestabilityofthemower.
Keep all movement on the slopes slow and gradual. Do not make sudden changes in speed or
direction.
Avoidstartingorstoppingonaslope. Iftireslosetraction,disengagethebladesandproceedslowly
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 8
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.

SERVICE: SAFETY
• Useextracareinhandlinggasolineandotherfuels. Theyareflammableandvaporsareexplosive.
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 fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers
on the ground away from your vehicle before filling.
When practical, remove gas-powered equipment from the truck or trailer and refuel it on the ground. If this
is not possible, then refuel such equipment on a trailer with a portable container, rather than from a gasoline
dispenser nozzle.
If a gasoline dispenser nozzle must be used, keep the nozzle in contact with the rim of the fuel tank or
container opening at all times until fueling is complete. Do not use a nozzle lock-open device.
• 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

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 Sharp Blades Throughout The Cutting Season. This is very important. Optimal
mulching performance cannot be obtained with dull or nicked up blades.
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!
