The new 5710D horizontal grinder from Eugene, Ore.-based Peterson has been designed for operations that require frequent moves between jobs without a special permit, according to the company.

Powered by a Tier IVi Caterpillar C27 1,050 horsepower engine, the 5710D has the power to handle tough jobs, says Peterson.

The 5710D, which weighs in at 88,500 pounds, can be equipped with an optional transportation dolly that allows the Peterson 5710D to be easily moved and then setup for operation within minutes, the company says.
With a feed opening of 60-by-40 inches combined with Peterson’s high lift feed roll, the 5710D is designed to reduce a wide range of material, including stumps.

The 5710D uses Peterson’s Impact Release System that can be set in the detent mode to provide consistent product sizing or switched to the floating anvil mode for a primary reduction where accurate sizing is less critical. The floating anvil mode provides what the company calls high-production primary reduction with more protection from contaminated feedstocks and reduced fuel consumption.

The 5710D’s new generation of controls includes Peterson’s Adaptive Control System and a fully adjustable feed system that can be optimized for a wide range of materials.

The 5710D also features a large grate area that enables the 5710D to produce materials to exact specifications. A quick-change multiple grate system is designed to make it easy to customize grate configurations to produce a wide variety of finished materials. Grates are removed through an enlarged access door on the side wall of the 5710D.

Another innovation included on the 5710D is Peterson’s Impact Cushion System. Urethane cushions allow movement of the compression roll/anvil housing pivot shaft, cushioning impacts caused by contaminants in the feed material. Shear pins above the cushion and a sensing circuit that stop the engine help protect the shaft from catastrophic damage in the event of a severe impact. More information on the 5710D is available at
