Proposal to remove the possibility of different technical requirements being applied by Type Approval Authorities when mechanical couplings for agricultural tractors with a maximum speed in excess of 60 km/h are submitted for type approval testing. The amendment would align requirements with European Union approvals which are accepted to be technically correct in design and safe to use at all speeds. This is achieved by the removal of the clause in annex 6 that requires different technical requirements for mechanical couplings to be used on agricultural tractors with a maximum speed in excess of 60 km/h.
