  • Patent number: 7025556
    Abstract: An agricultural transfer table enables rapid transfer of harvested agricultural material from a dump truck to a silo or the like. The agricultural transfer table comprises a box with an open front end. Apron chains in the box propel the material to the box back end, where cross chains discharge the material out a selected side. A prime mover and hydraulic system are part of the agricultural transfer table, so no source of external power is required to operate it. A tongue is closeable to enable the agricultural transfer table to be towed by a tractor. The tongue is openable to allow the truck to back up close to the agricultural transfer table front end. The front end is tiltable downwardly toward the ground. The truck back wheels back up ramps at the front box end. The ramps are storable inside the box when the agricultural transfer table is towed.
