Swather hitch device for pull-type implements
First Claim
1. A towed implement control device for an implement with an implement tongue at one side thereof, the tongue having a hitch for connection to the draw bar of a towing vehicle, said control device comprising:
- a strut pivotally mounted on the implement tongue and projecting laterally from the tongue to a side thereof opposite the implement;
a control tongue extending along the side of the implement tongue opposite the implement and slideably connected to the strut;
control hitch means pivotally connecting the control tongue to the towing vehicle at a position adjacent the draw bar hitch;
spring means acting between the control tongue and the strut to resist relative sliding movement of the control tongue and the strut; and
a beam pivotally connected to the strut and pivotally connected to the implement tongue, at a position further from the hitch than the strut.

Abstract
A control device is mounted on the tongue of a drawn implement, normally an implement that extends to one side of the tongue. The control device includes a strut that is mounted on the tongue of the towed implement and projects laterally from the tongue, to the side away from the projection of the implement itself. A stabilizer tongue is slideably connected to the strut and is connected at its front end to a second, rigid hitch beside the hitch for the implement tongue. Springs act between the strut and the stabilizing tongue to resist movement of the stabilizing tongue with respect to the strut. The control device balances the tendency of the offset implement to move laterally when towed and improves its steering characteristics.
