Section 1: Assembly & Set-up
•
Two duplex outlets are required if the wings are raised
and lowered simultaneously. (Factory standard)
•
Three duplex outlets are required if the wings are
raised and lowered independently.
•
on page 43 is available
for adding an extra outlet if the tractor does not have
the required number of duplex outlets.
Before You Start
Read and understand the operator’s manual for your
cutter. An understanding of how it works will aid in the
assembly and setup of your cutter.
It is best to go through the
before assembling the cutter. Speed up your assembly
task and make the job safer by having all needed parts
and equipment readily at hand.
Torque Requirements
See
“Torque Values Chart”
on page 64 to determine
correct torque values when tightening hardware. See
exceptions to common torque values
Assembly Checklist
Check
Reference
Have a fork lift or loader with properly sized chains and
safety stands capable of lifting and supporting the
equipment on hand.
Have a minimum of two people available during
assembly.
Make sure all major components and
loose parts are shipped with the machine.
Operator’s
Manual
Double check to make sure all parts,
fasteners, and pins are installed in the
correct location. Refer to the Parts
Manual if unsure. By double checking,
you will lessen the chance of using a bolt
incorrectly that may be needed later.
NOTE:
All assembled hardware from the
factory has been installed in the correct
location. Remember location of a part or
fastener if removed during assembly.
Keep parts separated.

DANGER
!
To avoid serious injury or death:
Do not use a power take-off adapter. The adapter will increase
strain on the tractor’s power take-off shaft causing possible
damage to shaft and driveline. It will also defeat the purpose
of the tractor’s power take-off shield.
WARNING
!
To avoid serious injury or death:
•
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.
•
Power take-off and/or driveline damage may occur if
distances “A” and “B” are not properly maintained.
Maintain proper distance, dimension A, between center
of drawbar hitch pin hole and end of power take-off shaft.

Hydraulic Outlets
The number of tractor hydraulic duplex outlets is
dependent upon how the Rotary Cutter is set-up.
Do use a power take-off adapter. It
can damage the power take-off drivetrain.
