Abstract
In a swather a support arm is attached to the header to carry the heavy hydraulic hoses which are connected to the tractor for supplying the drive fluid to the hydraulic system of the header. The support arm is articulated so as to accommodate the up-and-down and twisting movement of the header relative to the tractor during harvesting action and this supported to prevent collapse when the hoses are disconnected from the tractor manifold. The support arm is attached at the rear to the tractor preferably at the wheel strut by a releasable ball joint coupling. From the coupling at the wheel strut, there is a free portion of the hydraulic hoses which extends to the manifold at the tractor where the ends of the hoses are attached to manually graspable handle portions which can be lifted away and the attached to a bracket on the support arm.
