ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to an apparatus for transporting a large pull type farm implement to a farm field for work. Existing methods of transporting large pull type implements to the field generally include hauling the implement on a trailer, or pulling the implement sideways on wheels, or folding the implement to make it narrow enough to pull down the roadway. Usually the trailer method is not convenient, it requires loading the trailer, something to pull the trailer, unloading from the trailer and hooking up to the tractor. Secondly putting a wheels on a implement to pull it sideways sometimes is not practical by design and causes problems in the field work. The third method of folding a implement can cause design problems and additional expense, and can cause the implement to be inferior to nonfolding implements.
SUMMARY OF THE INVENTION
Accordingly, it is the object of the present invention to provide an implement transport arrangement which is particularly suited to moving a farm implement on a roadway safely, conveniently and economically, and when reaching the field transforming into part of the implements working parts, and function as part of the implement in a safe, convenient and economical manner.
According to the invention, one thing that makes the implement transport system unique is that it adds desirable characteristics to the implement that it is affixed to when the implement is in working mode in the field. There are four assemblies in the implement transport, the hitch assembly, the carrier assembly, the turret assembly and the trailer assembly. The hitch assembly, the carrier assembly and the turret assembly are active assemblies when the implement is engaged in field work. The hitch assembly becomes the implements hitch, the carrier assembly becomes the implements tongue, and the carrier assembly and turret assembly become the implements main frame structure. So these three assemblies perform functions in both field mode and transport mode. Using these three assemblies in field mode and transport mode provides for and economical system. A second unique and desirable characteristic of the implement transport is that it is positioned above the implement and can be made the height needed to fit the implement so as not to impose design restrictions in the implement. A third unique and desirable characteristic of the implement transport is using pivot tubes versus pivot pins in the hitch horizontal pivot and in the turret horizontal pivot. This provides a means to route the mechanical power take off from the tractor to the implement thru the center of the hitch pivot tubes and thru the center of the turret pivot tube. Routing the mechanical power take off thru the center of the pivot tubes puts the mechanical power vertical drive shafts on the same axis as the pivot tubes, which eliminates binding the mechanical drive shafts when turning corners, and provides for a very efficient energy transfer from the tractor to the implement. Also, this arrangement provides a means to route mechanical power to a side pull center pivot machine such as a mower conditioner efficiently. A fourth desirable characteristic of the implement transport is its easy transformation from field mode to transport mode and from transport mode to field mode. All functions to switch modes are performed from the tractor, basically, it is raise the transport, rotate the implement to the desired position and it is ready for transport, to ready for work, rotate the implement to the desired position, lower the transport and it is ready for work.
