2019 Rotochopper B66-T

3,621 hours on a 2019 Rotochopper B66-T — that’s roughly 600 hours per year on a 950HP horizontal grinder. That level of use is typical for a production machine and is paired with excellent condition and useful extras.

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 — high horsepower with strong condition

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 3,621 hours over 6 years, you’re looking at about 600 hours per year. That reflects steady production use, which is expected for a grinder in this category.

The Rotochopper B66-T is a track-mounted horizontal grinder, allowing for mobility around job sites while maintaining controlled feeding for consistent material sizing.

This unit is reported to be in excellent condition, which is a strong indicator of proper care and maintenance.

It includes a transport dolly, making it easier to move between job sites. It also comes with a set of screens and additional inserts and parts, adding flexibility and reducing downtime.

Machines in this class are typically used in high-volume operations where throughput and consistency matter. Buyers should still evaluate wear components as part of normal inspection, but condition and included extras add value.

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