2018 Rotochopper B66L

3,337 hours on a 2018 Rotochopper B66L — that’s roughly 475 hours per year on a 950HP horizontal grinder. That level of use is moderate for this class and is supported by major component replacements.

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
• Mulch producers — ideal for high-volume production and consistent output
• Operators needing production output — strong 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 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 950HP CAT C27 engine. That level of horsepower places it in the high-production class, capable of handling large, dense material without slowing down under load.

With 3,337 hours over 7 years, you’re looking at about 475 hours per year. That reflects steady use without being excessive for a grinder in this category.

This machine has had major updates. The main bearings and mill were replaced in April 2020 at approximately 1,500 hours, which means those components have significantly fewer hours than the rest of the machine.

It also includes new belly and discharge belts with less than 100 hours of use, which are critical components for material flow and operation.

This unit runs great and comes with spare parts, helping reduce downtime and maintenance costs. It also includes a transport dolly, making it easier to move between job sites.

The Rotochopper B66L is designed for high-volume production and consistent end-product quality, especially in mulch and regrind applications.

Buyers should still evaluate wear components as part of normal inspection, but recent updates add strong value and reduce immediate maintenance needs.

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