State of California to cause cancer, birth defects or other reproductive harm.
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.

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.

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.

TROUBLESHOOTING
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.
