Harvester 1 has horizontal and vertical pivots 4, 3 interconnecting front and second drawbars 2, 5. Drawbar 5 is attachable to the lower three point linkage of a tractor (not shown) for effecting raising or lowering of the front of harvester 1. Point 4 allows for sideways rocking motion between tractor and harvester over uneven ground. Pivot 3 allows drawbar 2 to swing across the front of the harvester for an enhanced turning circle of the tractor/harvester.
