The LumpBuster is designed to remove lumps from fertilizer at the same speed as your auger — no matter how large the clumps are. It consists of a series of timed, studded shafts that spin to break up hard or lumpy fertilizer. The LumpBuster increases efficiency: it breaks up fertilizer without employing typical methods like a piece of expanded metal, mesh screens, or forcing farmers to discard large lumps of otherwise usable fertilizer.
