Abstract: An ensilage loader for removing ensilage from a body of ensilage, as in a trench silo, stack or other storage and discharging same into a receiver, such as a feed mixer or the like, is mounted on a mobile frame and includes an ensilage receiver adjacent one end of the frame to receive ensilage removed from the face of the ensilage body and having operative members to move same into a conveyor or elevator for delivery thereof to a feed mixer or the like. The ensilage loader includes a digger mounted on a boom having one end mounted on the frame and arranged with power members in a manner for selective raising and lowering of the digger, extension and contraction of the boom with lateral movement relative to the ensilage receiver. The loader includes controls whereby the digger cuts into a face of the ensilage body leaving a substantially vertical face without an overhang and moves the ensilage into the ensilage receiver.
