Section 1: Assembly & Set-up
Hydraulic Set-up
The number of tractor hydraulic duplex outlets is
dependent upon how the Rotary Cutter is 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. (Requires
wings independently.)
•
If the tractor does not have the necessary number of
duplex outlets, there are control valve kits available to
add outlets. See
38 for a complete description of the kits.
Torque Requirements
See
“Torque Values Chart”
on page 58 to determine
correct torque values when tightening hardware. See
exceptions to common torque values.
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.
Assembly Checklist
Check
Ref.
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.
