Peterson’s 3300B Drum Chipper is a radical departure from traditional drum chippers. With a 540 hp (402 kW) Tier III or Tier IV Caterpillar engine, the 3300B has the power to handle up to 24-inch (61 cm) diameter logs. With large access doors on both sides of the machine for service-ability, the fully enclosed engine compartment keeps things clean.

The 3300B’s transverse design allows for a much smaller oper-ations deck, providing flexible production configurations in

diverse terrain. With 230-degrees of rotation, the end-load or optional top-load spout design allows trailers to be loaded in a variety of positions, depending on the demands of the job site.

Using the proven drum and knife design from the larger 4300-series drum chippers, the 3300B's main components are robust and offer long life. The 3300B is available with a four-pocket drum for typical biomass chips, or an eight-pocket drum for microchipping applica-tions. The chips exit the machine

from an innovative auger system which feeds an accelerator to increase payload density.

The 3300B is available with an optional powered feed deck, allowing for shorter stems and tops. Both the powered- and standard fixed feed deck can be stowed for transportation purposes.

Innovative Anvil DesignThe robust, two-sided anvil is easily serviced through an access panel from ground level. Adjusting the anvil position can be completed by one person in a matter of minutes.

Heavy-Duty Knife AssembliesProduced from the highest quality alloy chromium steel, heavy-duty Peterson knife assemblies achieve uniform production of wood chips with high accepts and minimal losses.

Superior Product SizingPeterson's grate system provides ultra-consistent chip sizing; twigs and small stems which can be difficult to size are easily fractured through our innovative system.

4- or 8-Pocket Drums AvailableFeaturing durable AR400 wear surfaces, the 3300B comes standard with a 4-pocket drum rotor with one Babbitt knife per pocket. An 8-pocket drum rotor is available for chipping microchips.
