DRIVE SYSTEM FOR SILO UNLOADER abstract of The Disclosure A drive system is provided for a silo unloader, in which a generally radially disposed auger at the bottom of a silo, both rotates about its own axis, and sweeps across the bottom of the silo floor. A sweeping movement is provided by a hydraulic drive. The rotation of the auger about its own axis is provided by an electric motor drive that traverses a silage dischargeway disposed at the general center of the silo, and that drives the auger from its radial inner end. A protective covering is provided for part of a drive chain that connects an electric motor drive disposed outside the dischargeway with a portion of the drive train located inside the dischargeway. The electric motor drive is mounted for responding to a certain level of resistance to the auger turning on its own axis, that is engendered by silage contact, whereby the motor will pivot on its mount in reactive response to the motor torque developed in driving the auger in rotation on its own axis, with the pivotal movement of the motor being operationally connected to the hydraulic drive that effects the sweeping movement of the auger, to discontinue the provision of hydraulic fluid to the sweeping-motion-drive, until silage resistance is reduced.
