Abstract
A material distribution system for stick-like objects such as railroad spikes includes a rake for peeling the stick-like objects from the top of a pile, and transferring them to another location, for example, where they might be reached by a human operator. Use of the rake to peel the object from the top of the pile, with minimized downward pressure applied by the rake, minimizes the tendency of the objects to entangle with each other.
