•
Do not operate and/or travel across inclines where tractor
and/or implement can rollover. Consult your tractor’s
manual for acceptable inclines the tractor is capable of
•
Do not raise the wing off the ground when traveling across
an incline. The weight of the wing will increase the risk of a
•
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
•
Always follow “Tractor Shutdown Procedure” provided in
this manual before dismounting the tractor.
•
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.
•
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.
•
Wait for blades to come to a complete stop before accessing
blade bolts through blade bolt access hole.
•
Do not use implement to lift objects; to pull objects such as
fence posts, stumps, etc; or to push objects. The unit is not
designed or guarded for these uses.
•
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.
•
Perform scheduled maintenance. Check for loose
hardware, missing parts, broken parts, structural cracks,
and excessive wear. Make repairs before putting the
•
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
•
Avoid catching hydraulic hoses on brush, posts, tree limbs,
and other protrusions that could damage and/or break them.
•
Buildup of debris around moving components and
gearboxes is a fire hazard. Keep rotating parts and
gearboxes free from debris to avoid serious injury and
•
Improper oil level can cause bearing failure and be a fire
hazard. Maintain proper gearbox oil level to avoid serious
•
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.
•
Do not operate a broken or bent driveline. Such a driveline
will break apart while rotating at high speeds and can cause
serious injury or death. 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 is set-up to operate
at the implement’s rated power take-off speed or equipment
breakage may result. RC models are rated for 540 rpm and
RCM models are rated for 1000 rpm.
Avoid Extreme Turning Angles
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 exceeds driveline maximum turning
angle. If the turn cannot be avoided, disengage tractor
power take-off and wait for the driveline to stop rotating
before making the turn.

Constant Velocity Driveline:
Maximum turning angle = 80

IMPORTANT:
Maintain correct power take-off
speed. Loss of power take-off speed will allow
blades to swing back and result in ragged, uneven
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.
