- Model 4310B - Track Mounted Drum Chipper



The 4310B Highwalker track mounted drum chipper is suited for high volume biomass producers who have a wide variety of feed material from brush and small feed stock to logs up to 24 inches (61 cm) in diameter. The 4310B is powered by a 765 horsepower (570 kW) C18 Caterpillar engine. At 58,500 pounds (26 535 kg), the track mounted 4310B is designed for operations requiring high production and frequent moves between jobs.

The chipper utilizes a 36 inch diameter by 44¾ inch (91 by 114 cm) wide drum with either 6 or 12 knife pockets. Traditional babbitt type knife systems are standard equipment. Chip length can be set from 1⁄8 to 1¼ inch (3 to 32 mm) depending on rotor and knife configuration. Peterson’s chip accelerator system, adds load density, or throws chips well away from the machine for land clearing operations.

With a ground clearance of 2’-10 1/8” (86 cm), the Highwalker makes it easy to traverse even the most rugged terrain.

Other key features include a hydraulic clutch, sloped feed deck for ease of feeding the chipper, and wear resistant AR 400 wear surfaces on the drum pockets and shell. Optional material sizing grates further reduce oversize twigs and branches in the chips, and an optional chip accelerator helps with loading.

The 4310B comes equipped with a wireless remote transmitter, putting control in the palm of your hand.

The end load spout is standard, and an optional top loading spout is available.

Since 1981, Peterson has specialized in the developing of delivery and processing equipment that turns low-grade organic materials into high value products.

The Adaptive Control System Features Intuitive Interfaces

The large display provides information to make chips more efficiently. On-screen maintenance instructions and self-diagnostics features increase your up-time.

Aggressive Feeding System

A sloped feed deck and three strands of WHD 120 feed chain, paired with an aggressive feed roll make loading the 4300-series easy in all types of material.

Knife Assemblies: At The Heart Of The Chipper

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

Select From 6 or12-Pocket Drum Styles

Featuring durable AR450 wear surfaces, the 4310B comes standard with a 6-pocket drum rotor with one Babbitted knife per pocket. A 12-pocket drum rotor is available for chipping microchips.

Superior Product Sizing

Peterson’s secondary grate system provides ultra-consistent chip sizing; twigs and small stems which can be difficult to size are easily fractured through our innovative system.
