The auger is a system on your BOSS hopper spreader. Shaped like a corkscrew, the auger spins to spread particulates at around 2.3 cubic feet per minute.
Pintle Chain System
Pintle spreaders are an optional upgrade onto your VBX and FORGE spreaders at the time of purchase. Please note, VBX 3000 spreader features the auger only. The Pintle Chain features a chain with a pivot point on each link. It also features two rotating shafts, bearings, sprockets, and tensioning devices.
