ABSTRACT:
A grain bag unloader is described for unloading grain from a grain bag wherein the unloader is moved rearwardly and operated by a tractor. The grain bag unloader includes a wheeled frame having a grain hopper at the rearward end thereof with a transversely extending unloading auger which is adapted to be inserted into the lower end of a field grain bag and which conveys grain from the grain bag into the grain hopper. The grain bag unloader also includes a discharge auger which extends upwardly and laterally from the grain hopper. The grain bag unloader also includes a grain bag winder tube. The grain unloader includes a first clutch which is able to disengage the operation of the unloading auger while permitting the discharge auger to continue to operate. The grain bag unloader also includes a second clutch which is designed to disengage the bag winder tube.
