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

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.
