Knife Assemblies at the Heart of the Chipper

Produced from the highest quality alloy chromium steel, heavy-duty Astec knife assemblies achieve uniform production of wood chips
with high accepts and minimal losses.

Select from 6- or 12-Pocket Drum

Featuring durable AR400 wear surfaces, the 4300 series Drum Chippers comes standard with an 6-pocket drum rotor with one Babbitted knife per pocket. A 12-pocket drum rotor is available for chipping microchips.

Discharge Spout Options

Two discharge spouts are available on all Peterson Drum Chippers. An end-load spout designed to load closed-top chip vans. A top-load discharge spout is also available and designed to load open-top chip vans.

Superior Product Sizing

Peterson’s drum chipper grate system provides ultra-consistent chip sizing; twigs and small stems which can be difficult to size are easily fractured through our innovative system. The chipper grate is located next to the chipper drum and ensures that materials passing through the grate meet a specific size requirement.
