Abstract: A trailer to be towed behind a vehicle has a convertible trailer hitch mounting on its front end in which a connecting portion of a trailer hitch is detachably secured so either a straight draw bar connected hitch or a gooseneck fifth wheel connected hitch may be used on the trailer. The hitch mounting has an upwardly open frame with forwardly converging thrust plates at its lateral extremities, while the trailer hitch connecting portion has a base plate that seats in the frame and integral forwardly converging side plates that abut the thrust plates of the hitch mounting frame.

Abstract: A feed residue saver attachment for combines has a trough adapted to be mounted in a transverse position beneath the rearward portion of a combine to receive residue which the combine would otherwise discharge onto the ground. A driven auger in the trough moves residue out an open end and into an impeller housing from which it is blown through a duct into a wagon. The attachment has alternative modes of operation so that it may be selectively used either to save substantially all the feed residue including chaff, or to save substantially only large material such as corn cobs, corn husks and pieces of stalk (known in some farming areas as "husklage") and permit chaff and other fine material to drop to the ground.
