Breakaway - Tiger RBM16 Operator's Manual

BREAKAWAY

The machine is fitted with a hydraulic breakaway device which protects the structure of the
machine should an unforeseen obstacle be encountered.
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 utilised to manoeuvre the head away from
the obstacle. NEVER CONTINUE FORWARD MOTION TO DRAG THE HEAD AROUND
THE OBSTACLE IN BREAKBACK POSITION.
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.
On mid-cut machines the geometry of the breakaway will cause the head to initially move
outwards in addition to rearwards. Therefore be aware that the breakaway action will be
impeded if the outer end of the head is working against a steep bank. In this circumstance
extra care must be taken during operation to avoid this occurrence.
Breakaway occurs at the slew column pivot. When an obstacle is encountered continued
forward motion causes the pressure in the slew ram base to rise until the relief valve
setting is exceeded.
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
