OPERATION
6 OPERATION
6.1 OWNER/OPERATOR
RESPONSIBILITIES
CAUTION
• It is your responsibility to read and
understand this manual completely
before operating the mower conditioner.
Contact your dealer if an instruction is
not clear to you.
• Follow all safety messages in the manual
and on safety signs on the machine.
• Remember that YOU are the key to
safety. Good safety practices protect you
and the people around you.
• Before allowing anyone to operate the
mower conditioner, for however short a
time or distance, make sure they have
been instructed in its safe and proper
use.
• Review the manual and all safety related
items with all operators annually.
• Be alert for other operators not using
recommended procedures or not
following safety precautions. Correct
these mistakes immediately, before an
accident occurs.
• Do not modify the machine. Unauthorized
modifications may impair the function
and/or safety and affect machine life.
• The safety information given in this
manual does not replace safety codes,
insurance needs, or laws governing your
area. Be sure your machine meets the
standards set by these regulations.
• Ensure that the tractor is properly
equipped to safely operate the mower
conditioner. This may include adding
ballast according to Tractor Operator’s
Manual requirements for attachments of
this size and mass.
6.2 OPERATIONAL SAFETY
Follow these safety precautions:
CAUTION
• Follow all safety and operational
instructions given in your tractor
Operator's Manual. If you do not have a
tractor manual, get one from your dealer
and read it thoroughly.
• Never attempt to start the tractor engine
or operate the mower conditioner except
from the tractor seat.
• Check the operation of all controls in a
safe clear area before starting work.
• Do not allow riders on tractor or mower
conditioner.
• Never start or move the machine until
you are sure all bystanders have cleared
the area.
• Avoid travelling over loose fill, rocks,
ditches or holes.
• Drive slowly through gates and
doorways.
• If cutting ditch banks, use extreme
caution. If the mower conditioner hits an
obstruction, the front of the tractor will
usually swerve towards the ditch.
• When working on inclines, travel uphill or
downhill when possible. Be sure to keep
tractor transmission in gear when
travelling downhill.
• Never attempt to get on or off a moving
tractor.
• Do not get off the tractor while the mower
conditioner is in operation.
• Stop tractor engine and remove key
before adjusting or removing plugged
material from the machine. A child or
even a pet could engage the drive.
• Check for excessive vibration and
unusual noises. If there is any indication
of trouble, shut down and inspect the
machine. Follow proper shutdown
procedure:
o engage tractor brake
o disengage PTO
o turn off engine and remove key
o wait for all movement to stop
o dismount and close lift cylinder
valves before inspecting raised
machine.
(continued next page)
Form # 169053 17 Model Year - 2009
OPERATION
• Operate only in daylight or good artificial
light.
• Keep everyone several hundred feet
away from your operation. Ensure
bystanders are never in line with the
front or rear of the machine. Stones or
other foreign objects can be ejected from
either end with force.
• Extreme care must be exercised to avoid
injury from thrown objects. Do not,
under any circumstances, operate the
mower-conditioner when other people
are in the vicinity. Stones and other
objects can be thrown great distances by
the rotating cutting blades.
• The cutterbar curtains are very important
to reduce the potential for thrown
objects. Always keep these curtains
down when operating the mowerconditioner. Replace the curtains if they
should become worn or damaged.
