Abstract
A drivetrain and load bearing swivel hitch assembly is provided which separates the load carrying function from the power transmitting function and features a swivel hitch assembly having three axes of rotation which allow for roll, pitch and yaw movement, respectively. One end of the load bearing swivel hitch assembly is secured to an implement such as a peanut combine, while the other end is securely joined to the drawbar of a pulling vehicle such as an agricultural tractor in a manner such that the draft and tongue load are not borne by the drivetrain assembly. Drivetrain assembly includes a swivel gearbox having a generally vertical axis above the generally vertical yaw axis of the load bearing swivel hitch assembly. Combines incorporating this drivetrain and load bearing swivel hitch assembly are also provided in order to present combines that will maintain the proper operational angle for combine operation irrespective of the tractor type or size used as the pulling vehicle.
