ABSTRACT:
The present invention provides a stock barrier comprising a number of rigid metal panels of open grid construction, the panels being arranged to lie in a normal operational position at an angle to the ground to thus form a pair of back-to-back ramps across which stock will not cross but which can be flattened to the ground against a resilient return force when a vehicle drives across. The panels are pivotable upwards from the flattened position, about a side edge thereof whereby to leave a clear path for stock to pass through the barrier when required.
