ABSTRACT:
A dual implement hitch for connection between a tractor and the implements for moving the implements to preferably an echelon position for field operation and to a tandem position for transport, while maintaining the tractor hitch pin on the line of pull of the implements. The hitch includes a hitch tongue pivotally connected to the tractor and to a support attached to the first implement. A curved beam is pivotally connected to the support forward of the tongue connection thereto and extends rearwardly over the first implement in the transport position to a caster wheel support and a pivotal connection to the second implement. Link means are pivotally connected to the hitch tongue and curved beam rearward of the pivotal connection of the curved beam to the support. A single hydraulic cylinder connected to the support and tongue provides the power for the movement of both implements to the noted positions from the tractor seat.
