Abstract
In its simplest form, a single unit implement such as a swather or the like, can be moved from field position to transport position by moving the rear offside wheels to the desired angle and fixing them in this position and allowing the near side rear wheel to castor freely. When used with multiple units, a tandem hitch is secured to the existing hitch of the front implement and extends to the next following implement with the rear wheel being positioned as heretofore. Adjustment may be provided between the adjacent units to set the relationship of the trailing unit relative to the leading unit.
Claims17
In pull type implements such as swathers and the like which include a frame including a transverse rear member, the improvements comprising means for mounting at least two such implements selectively in field working position whereby said implements are in echelon one behind and to one side of the other, and at least one transport position, said means including a rear offside wheel assembly for each implement operatively mounted thereto for selective castoring action from a straight ahead orientation when in field working position, to orientations at an angle to the fore and aft axis of the implement when in the transport position, means to detachably lock said wheel assemblies in any of the said orientations, a hitch pole assembly for each implement extending forwardly from one end of said transverse rear member, said hitch pole assembly of said one implement being connected by the front end thereof to adjacent the outboard end of said transverse rear member of the other of said implements.
