The ThunderBuster is designed to remove clumps from fertilizer at the same speed as your auger — regardless of size. It consists of a series of timed, studded shafts that spin to break up hard or clumpy fertilizer.

The ThunderBuster 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.
