8. 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 maneuver 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 'SLEW' selected
When the slew relief valve setting is exceeded oil is displaced from the slew cylinder allowing the arm to pivot backwards horizontally and the obstacle to be cleared.
Powered Slew
The slew feature allows a 95° arc of powered arm movement on the working side from right angles to the tractor to 5º beyond the direct line back.
The feature is required to place the machine in the transport position but can also be used to swing the arm back and forth while cutting awkward areas and corners to avoiding the need to constantly reposition the tractor. To operate in this way, 'SLEW' must be selected on the control assembly.
If breakaway occurs the slew motion must be reversed to allow the slew breakaway relief valve to reset and the ram to become operable again.
Extra care must be taken when working in 'SLEW’ mode with the reach fully in – IT IS POSSIBLE FOR THE FLAILHEAD TO HIT THE TRACTOR OR MACHINE FRAME.
