2008 Peterson Pacific 6710B

10,000 hours on a 2008 Peterson Pacific 6710B — that’s roughly 590 hours per year on a 1,200HP horizontal grinder. This is a high-production machine with major rebuild work already completed.

Who This Machine Is For

• Large land clearing operations — handles high volumes of brush, timber, and stumps
• Recycling yards — processes wood waste into reusable material
• Forestry contractors — built for grinding whole trees and dense material
• Operators needing maximum production — high horsepower with rebuilt components

What It Grinds

• Brush and green waste — reduces volume for hauling or reuse
• Wood waste — processes pallets and scrap lumber
• Whole trees and large timber — handles heavy material with controlled feed

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 1,200HP CAT C32 engine. That level of horsepower places it in the ultra high-production class, capable of handling large, dense material continuously without slowing down.

With 10,000 hours over 17 years, you’re looking at about 590 hours per year. That reflects steady production use, which is typical for grinders in this category.

The engine has had an out-of-frame rebuild performed by a CAT dealer and comes with a CAT Gold warranty. That is a major value point, as it significantly reduces risk on one of the most expensive components.

Additional updates include a new floor and a rebuilt clutch. These are key components that directly impact material handling and overall machine performance.

The Peterson Pacific 6710B is a horizontal grinder with a controlled feed system, allowing for consistent material sizing and efficient processing in high-volume operations.

Buyers should still evaluate wear components such as the mill, teeth, and conveyor system as part of normal inspection, but major rebuild work adds confidence in continued use.

If you’re comparing options, you can also view other horizontal grinders or check tub grinders if your operation prefers gravity-fed loading.
