ABSTRACT:
This invention is a plough consisting of at least two booms pivotally connected together about a joint which can be locked to enable the booms to extend in line with each other, each carrying plough shares extending to one and the other side of the tractor so that a very large number of shares can be pulled by a single tractor. The pivot joint can be released to enable one boom to swing in relation to the other when not ploughing so that the total width of the tractor and plough is not too great to be driven along roads and through narrow openings into fields and so on. There may be boom at the other end of the fixed boom capable of pivoting about a similar joint towards the tractor. The one boom is arranged to be mounted on the tractor three point linkages so that it can be lifted by that linkage when not ploughing, and the other, or other booms can have wheels associated with jacks for lifting the shares clear of the ground enabling the wheels to run over the ground when not ploughing.
