  • Patent number: 6742600
    Abstract: A coupler for attaching an implement to a tractor is provided. The coupler has three pivot arrangements allowing pivoting about three axes that are generally normal to one another with two axes of pivoting lying in substantially in a first plane and the third axis of pivoting intersecting that plane at a variable angle in a second plane generally perpendicular to the first plane. The three axes of pivoting substantially intersect and the implement may be attached wherein the load from the implement is directed downwardly and over the draft arms of the tractor.
    Type: Grant

  • Patent number: 4310275
    Abstract: This invention provides a novel hay bale accumulator arranged in an improved baling system to mate with a tractor drawn baler and accumulate a batch of ten bales. The accumulator deposits the bales in orderly batches on the ground behind the array as the tractor moves at any selected speed by tilting the storage platform on which the bales are stored to slide the bales therefrom. The power consumption is low for the mechanisms operating the accumulator and can be derived from the standard tractor hydraulic system. A simplified low cost and easily maintained operating mechanism for the accumulator consists of two control devices actuating two hydraulic cylinders which respectively load bales from the baler onto the storage platform and tilt the storage platform for unloading an accumulated batch of bales on the ground.
