Abstract: A trailer useful for carrying combine cutter heads - either corn or small grains. The trailer avoids interference with the combine when loading the head and also maintains a proper load balance after the head is loaded. It does so by using a trailer-wheel axle which is movable from a normal road position with the wheels well under the load to a rear position where the wheels are considerably behind the driving wheel of the combine as that machine drives up to the trailer so that the head can be detached and loaded.

Abstract: A grain handling device for the receiving and transporting of grain and the like with the primary aspects of this invention being related to ground level receiving of such grain from a carrier, such as a truck, holding and controlling such grain and transporting such grain to a storage bin, typically at an elevation higher than that of the grain delivery carrier. The primary aspects of this invention are the positive control of the grain received from the truck into the grain receiving bin through the use of a valve disposed in the grain bin at the outlet thereof for control of the rate of flow of the grain from the grain holding bin into a grain transport. The valve is configured in a unique way to cooperate with sloping bin walls and the bin outlet to substantially seal such outlet in the valve closed position and to prevent bridging of grain within the grain receiving bin, thereby eliminating plugging at the grain bin outlet.
