An animal feeder system for dispensing feed onto a ground surface, including a tank configured for holding feed and having a bottom end for receiving a gravity flow of feed in the tank. A spreader mechanism is operably coupled with the bottom end of the tank, and is operable to receive a flow of feed from the bottom end of the tank and periodically dispense the feed onto a ground surface proximate the tank. A bulk dump system includes a discharge port positioned in the tank and configured for capturing feed in the gravity flow, and a feed valve coupled with the discharge port and selectively operable for dispensing the captured feed from the discharge port into a pile on the ground surface.
