  • Patent number: 4622806
    Abstract: A ditch swather comprises a transverse beam attached to single point hitch for drawing the beam forwardly in a direction transverse to its length with the beam support at either end by a pair of ground wheels. A swather section is pivotally mounted at one end of the frame and movable between a position inclined downwardly at 45.degree. to a position vertically upwardly by operation of a hydraulic cylinder. A gauge wheel at the end of the swather section remote from the frame controls the position of the swather section relative to the ground. The ground wheels at the end of the beam adjacent the swather section are mounted on a walking beam. The reel sickle knife and draper of the swather are hydraulically driven.

  • Patent number: 4460193
    Abstract: The table knife and reel assemblies of a swather are bolted to a main mounting beam which in turn is mounted on a pair of double wheel assemblies one each adjacent each end thereof. The hitch pole from the tractor or other source of power is pivotally secured adjacent one end of said main mounting beam. In the hydraulic embodiment, piston and cylinder assemblies move the pole and the wheels between the field and transport positions and in the mechanical embodiment, linkage is provided between the pole and the wheel assemblies and the pole is moved by the tractor. In the hydraulic embodiment, a sequencing valve may be provided in conjunction with the table adjusting piston and cylinder which operates the piston and cylinder controlling the wheels when the table is raised and lowered between the field and transport positions.
