9. BREAKAWAY
The machine is fitted with a hydraulic breakaway device which protects the structure of the machine should an
unforeseen obstacle be encountered.
NOTE: The breakaway function does not relieve the operator of his responsibility to drive carefully, be alert and
AVOID OBVIOUS HAZARDS BEFORE CONTACT OCCURS.
Breakaway may occur momentarily during normal work should an extra thick or dense patch of vegetation be
encountered. In these instances tractor forward motion may be maintained with care. Where breakaway has
occurred as a result of contacting a post or tree etc. the tractor must be halted and the controls of the machine
utilized to manoeuvre the head away from the obstacle. NEVER CONTINUE FORWARD MOTION TO DRAG
THE HEAD AROUND THE OBSTACLE IN BREAKBACK POSITION.
NOTE: The force required to activate the breakaway system will vary dependent upon the gradient of work. It
will require less force when working uphill and vice versa.
With 'AUTO RESET' selected:
When the slew relief valve setting is exceeded oil is
displaced from the slew ram into the base of the lift ram
which causes the head to rise as the arm pivots
backwards to clear the obstruction. Resetting of the
head into the work position occurs automatically.
With 'SLEW' selected:
When the slew relief valve setting is exceeded oil is
displaced from the slew ram allowing the arm to pivot
backwards horizontally and the obstacle to be cleared.
Re-setting the head into the work position is carried out
manually by selecting 'SLEW OUT' on the control
assembly
