Machine is in great condition and ready to work.

2006 Peterson 4710B

9,100 hours on a 2006 Peterson 4710B — this unit stands out because of extensive recent work and component updates. That level of maintenance adds real value for a buyer looking for a production grinder that has already had key wear items addressed.

Who This Machine Is For

• Land clearing contractors — handles continuous grinding of brush, timber, and stumps
• Recycling yards — processes wood waste into consistent, reusable material
• Forestry operations — built for grinding whole trees and dense material
• Operators wanting updated components — major wear items already replaced

What It Grinds

• Whole trees and large timber — horizontal feed handles long material efficiently
• Stumps — breaks down dense root systems into grindable material
• Brush and green waste — reduces volume quickly for hauling or reuse
• Construction wood waste — processes pallets, lumber, and mixed debris

This is not a chipper. It uses a hammermill system, so the output is ground material, not uniform chips.

Specs in Plain Language

This unit is powered by a 765HP CAT C18 engine. That level of horsepower puts it in the production class, capable of handling large, dense material without slowing down under load.

With 9,100 hours over 18 years, you’re looking at about 505 hours per year. That reflects a machine that has been used consistently in production environments.

This machine has had major updates, including new compression roll bearings, new compression roller housing wear plates, new hard facing throughout, a new air compressor, and a new anvil. These are key wear components that directly impact performance and uptime.

All fluids have been replaced except for the final drives, and a full fluid analysis was completed with excellent results. That gives added confidence in the condition of the machine’s systems.

The Peterson 4710B is known as a production horizontal grinder with controlled feeding, making it well-suited for consistent output and handling long material efficiently.
