2017 Rotochopper B66-T

2,700 hours on a 2017 Rotochopper B66-T — that’s roughly 340 hours per year on a 765HP horizontal grinder. That level of moderate use is supported by recent updates and remaining engine warranty.

Who This Machine Is For

• Land clearing contractors — handles brush, timber, and wood waste on job sites
• Recycling yards — processes material into reusable products
• Mulch producers — ideal for consistent, high-volume output
• Operators needing production output — solid horsepower with updated components

What It Grinds

• Brush and green waste — reduces volume for hauling or reuse
• Wood waste — processes pallets and scrap lumber
• Whole trees and timber — handles large 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 765HP CAT C18 engine. That level of horsepower places it in the high-production class, capable of handling a wide range of material without slowing down under load.

With 2,700 hours over 8 years, you’re looking at about 340 hours per year. That reflects steady use without being excessive for a grinder in this category.

This machine has had key updates, including a new infeed installed approximately 100 hours ago. The discharge conveyor and drive belts are also fairly new, which are important components for material flow and overall performance.

There are approximately 2,400 hours on the mill, giving buyers a clearer picture of wear on the grinding system compared to total engine hours.

The engine is backed by a CAT warranty, which adds value and reduces risk for major repairs.

The Rotochopper B66-T is a horizontal grinder designed for consistent material sizing and efficient processing in production environments.

Buyers should still evaluate wear components as part of normal inspection, but updates and warranty coverage add confidence.
