ABSTRACT:
This invention is a trailer plough having a double-length boom carrying twice as many shares as a conventional boom to enable a larger area to be ploughed at each pass of the tractor. The boom is in two parts connected together by a hinge having a universal joint at one end and a lost motion connection at the other end thereof, whereby the boom is hinged together for ease of manipulation at the ends of rows and also to enable the rear boom part to be lifted if, say when ploughing uphill, the tractor cannot pull the load due to the full number of shares.
