Abstract

A mobile feeder system is provided including a feeder having a center of gravity, and an intermediate feeder base supporting the feeder for horizontal movement between a cantilevered position in which the center of gravity lies outside the intermediate base and a non-cantilevered position in which the center of gravity lies over the intermediate base. A gathering device is also provided.
