Peterson 6700D Horizontal Grinder

Overview

The 6700D Horizontal Grinder is Peterson’s largest horizontal grinder, and is designed for operations  that need the most durable, highest output machine.

Powered by a 1125hp (839 kW) Tier IV, Caterpillar C32 engine or an export only Tier II Caterpillar C32 engine, the 6700D is designed for the toughest jobs.

With a feed opening of 66 x 50 inches (168 x 127 cm), the 6700D Horizontal Grinder can even process large stumps that used to be reserved for tub grinders. The grinder is particularly suited for land clearing operations or other applications where mobility is desired. System pressure transducers and remote monitoring capability simplify set up and provide complete engine and system parameters.
