WARNING
!
To avoid serious injury or death:
•
Allow only persons to operate this implement who have
fully read and comprehended this manual, and who have
been properly trained in the safe operation of this
implement. Serious injury or death can result from the
inability to read, understand, and follow instructions
provided in this manual.
•
Do not use a tractor that is too small or too large. Small
tractors can be pushed around and flipped over. Large
tractors can damage the attached implement. See “Tractor
Requirements” at the front of Section 1: Assembly & Set-up.
•
Cutter blades can continue to rotate while decelerating
after power take-off is disengaged. Remain on the tractor
seat until rotating parts come to a complete stop.
•
Always follow “Tractor Shutdown Procedure” provided in
this manual before dismounting the tractor.
•
Do not operate and/or travel across inclines where the
tractor and/or implement can rollover. Consult your
tractor’s manual for acceptable inclines the tractor is
capable of traveling across.
•
Do not raise the wing off the ground when traveling across
an incline. The weight of the wing will increase the risk of a
rollover.
•
Watch while making tight turns to ensure that the rear
tractor tires and lower 3-point arms do not make contact
with cutter hitch, driveline or deck. Keep lower 3-point
arms raised at all times when hitched to a pull-type cutter.
•
Avoid catching hydraulic hoses on brush, posts, tree limbs,
and other protrusions that could damage and/or break them.
•
Never carry riders on the implement or tractor. Riders can
obstruct the operator’s view, interfere with controls, be
pinched by moving components, become entangled in
rotating components, struck by objects, thrown about, fall
off and be run over, etc.
•
Operate only power machines equipped with a certified
Roll-Over Protective Structure (ROPS) and seat belt. Keep
folding ROPS in the “locked up” position when
appropriate. If ROPS is in the locked up position, fasten seat
belt snugly and securely to help protect against serious
injury or death from falling and machine overturn.
•
Do not operate a cutter with a hitch or hitch pin that is
excessively worn, bent, broken, or has structural cracks.
The hitch and/or hitch pin can break apart separating cutter
from tractor.
•
Perform scheduled maintenance. Check for loose
hardware, missing parts, broken parts, structural cracks,
and excessive wear. Make repairs before putting the
implement back into service.
•
Wait for blades to come to a complete stop before accessing
blade bolts through blade bolt access hole.
•
Do not use implement to tow other equipment unless it is
designed with a tow hitch. Doing so can result in loss of
control and damage the equipment.
•
Do not exceed rated cutting capacity of your cutter. See
specifications & capacities for specified cutting capacity.
Exceeding rated cutting capacity can damage drive
components, cutter blades, and deck components.
•
Buildup of debris around moving components and
gearboxes is a fire hazard. Keep rotating parts and
gearboxes free from debris.
•
Improper oil level can cause bearing failure and be a fire
hazard. Maintain proper gearbox oil level.
•
Do not operate a broken or bent driveline. Such a driveline
will break apart while rotating at high speeds. Always
remove the implement from use until the damaged driveline
can be repaired or replaced.
•
Some tractors are equipped with two power take-off speeds.
Be certain your tractor’s power take-off shaft is set-up to
operate the implement at its rated power take-off speed. Do
not exceed implement’s rated power take-off speed.
Excessive speed can damage drive components, cutter
blades, and/or increase the risk of a thrown object hazard.
RC models are rated for 540 rpm and RCM models are rated
for 1000 rpm.
Tractor Turning Angle
Refer to Figure 3-1:
Plan your field cutting to minimize number of turns,
especially extreme turning angles. Avoid tractor-to-cutter
turning angles that exceed 80
o
. If the turn cannot be
avoided, disengage power take-off and wait for the
driveline to stop rotating before making the turn.
Constant Velocity (CV) Driveline
Figure 3-1
IMPORTANT:
Maintain correct power take-off
speed. Loss of power take-off speed will allow
blades to swing back and result in ragged, uneven
cutting.
IMPORTANT: Do not let the wings flex down more
than 20 degrees while operating the cutter. Doing so
can cause damage to the cutter.
IMPORTANT:
If wing driveline profile is bent or
twisted, disconnect that driveline from the wing
gearbox before folding the wing up. This will protect
both the wing and divider gearboxes. Repair
driveline before putting cutter back into service.
