The warning system in this manual identifies
potential hazards and has special safety messages that
help you and others avoid personal injury, even death.
DANGER, WARNING and CAUTION are signal
words used to identify the level of hazard. However,
regardless of the hazard, be extremely careful.
DANGER signals an extreme hazard that will cause
serious injury or death if the recommended
precautions are not followed.
WARNING signals a hazard that may cause serious
injury or death if the recommended precautions are
not followed.
CAUTION signals a hazard that may cause minor or
moderate injury if the recommended precautions are
not followed.
Two other words are also used to highlight
information. “Important” calls attention to special
mechanical information and “Note” emphasizes
general information worthy of special attention.
The left and right side of the machine is determined
by sitting on the seat in the normal operator’s
position.

Operation
Using a mower with the carrier is similar to using it
in the mid–mount position. Therefore, you should
read and follow the operation and safety guidelines
explained in the Operator’s Manual for your mower.
Operating Tips
Turning
The mower may leave more uncut grass when turning
because it travels at a greater speed in a longer arc
than when mounted in the mid–mount position.
Therefore, it may be necessary to slow down before
entering a turn to maintain the quality of cut.
Also, the tractor is longer with this attachment, so
you should be careful when turning in enclosed areas.
Trimming
Use extra care when trimming. Travel at a slower
speed so you can watch for obstructions on which the
mower can get caught.
Terrain
Avoid using the attachment in areas with deep dips as
it can get caught on the far edge of a dip and dig into
the ground.
