The breakaway cylinder or tension bolt is used to
prevent structural damage to the cutter head and
parallel arms. If the cutter head strikes an object during
forward movement, the breakaway cylinder extends -
allowing the cutter head and parallel arms to pivot 90
degrees to the rear. This movement is identical to that
of the tension bolt, but the big advantage of the
breakaway cylinder is that it can be easily reset using
the tractor's remote cylinder control levers.
The breakaway cylinder should be installed on the
cutter as shown in Figure 3-5. Be sure that the rod end
of the cylinder is located on the pivot lug as shown.
Connect both hoses from the cylinder to a remote
outlet on the tractor. The tension bolt should never be
used in conjunction with the breakaway cylinder.
The breakaway cylinder is designed to bypass
hydraulic fluid under high pressure when the cutter
head or parallel arms strike an object during forward
movement. Do not use any standard hydraulic cylinder
for a breakaway cylinder or damage could occur to the
unit.
NOTE: All units equipped with the breakaway
cylinder also have a 1/2" tension bolt installed on the
breakaway plates for shipping purposes. This bolt
must be removed after the cutter is hooked up to the
tractor.
