ABSTRACT:
A harvesting machine particularly a swather comprises a frame carrying twin headers across the front of the frame and abutting centrally of the frame. The headers are mounted on pivot couplings arranged at respective front corners of the frame and of a type which allows the header to rotate through ninety degrees to a position along side the frame while at the same time causing the header to twist abut a longitudinal axis so that when it reaches a transport position along side the frame it is also raised. The movement from field transport position can be obtained by driving ground wheels at the outer ends of the headers. The reels can be moved longitudinally of the headers to accommodate pivotal movement of the headers caused by variations in field height.
