ABSTRACT:

BACKGROUND OF THE INVENTION
A farm implement can only be so wide and still be manageable in traveling between fields including use of public highways. Thus, multiple implements will be hitched in side-by-side relationship for field use and then positioned one behind the other for transport. There are many complicated hitch arrangements that address this need, but they suffer from being overly complex in structure and operation. What is needed is a simplified hitch that will readily allow a pair of implements to be quickly moved between a side-by-side field position and a trailing transport position.
SUMMARY OF THE INVENTION
Each of a pair of implements have a tongue assembly and a link extends between the implements connecting them together and pivots from a laterally extending position when the implements are in a field position to a position parallel to the line of travel when the implements are in a transport position. The link has posts at opposite ends which connect to the tongue assemblies of the implements. The link is telescopically extendable and has a hinge allowing the second implement to follow the contour of the land in both field and transport positions.
The tongue assembly of the second implement is pivotable between a forwardly extending position where it is connected to the tongue assembly of the first implement when the implements are in the field position to a laterally extending storage position when the implements are in a transport position.
The tongue assemblies of both the first and second implements have hinges allowing the implements to follow the contour of the ground when the implements are in the field position.
While the hitch assembly of this invention is suitable for implements performing a wide variety of different functions, it is particularly suitable for use with hay rake equipment, such as windrow fluffers. Windrow fluffers in the tandem side-by-side field position may each receive a windrow of hay and selectively discharge the hay into separate rows to the left, to the right, to the center, to the left and right, and to combine two or more windrows for harvesting two windrows at the same time
