Abstract

The invention relates to a portable drive-over grain hopper for use in moving grain. The hopper has an endless chain linkage with laterally extending paddle assemblies spaced therealong. A grain transfer bed extends from a low profile location in position to receive grain from a belly-dump or side-dump truck or trailer to a higher elevation discharge outlet. The grain transfer bed has a generally planar lateral width which is the same from the grain inlet to the discharge outlet, and is substantially spanned by each paddle assembly. Fold-down ramps are provided adjacent the inlet to allow a truck or trailer to drive over the grain hopper, which has a very low profile. The grain hopper has removable wheels and a removable hitch to allow it to be relocated as desired.
