2017 Rotochopper B66L

8,700 hours on a 2017 Rotochopper B66L — that’s roughly 1,240 hours per year, and this unit has a certified CAT engine rebuild with warranty remaining. That adds strong value for a high-production grinder in this class.

Who This Machine Is For

• High-volume recycling yards — processes large amounts of wood waste daily
• Land clearing contractors — handles continuous grinding of timber and debris
• Mulch producers — designed for consistent end-product sizing
• Operators looking for production capacity — high horsepower with rebuilt engine

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 for hauling or reuse
• Construction wood waste — processes pallets, lumber, and mixed debris

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

Specs in Plain Language

This unit is powered by a 1,000HP CAT engine. That level of horsepower places it in the high-production class, capable of handling large, dense material in demanding environments.

With 8,700 hours over 8 years, you’re looking at about 1,240 hours per year. That reflects a machine that has been used consistently in production settings.

The engine has been rebuilt and certified by CAT, and it still has warranty remaining. That is a major benefit for buyers and helps reduce concerns around engine life.

This unit includes a transport dolly, which helps move the grinder between job sites. That adds flexibility compared to fully stationary setups.

It is important to note that both the grinder and dolly will need maintenance and repairs. Buyers should plan for additional work depending on condition and intended use.

The Rotochopper B66L is known for producing a more consistent finished product, making it a common choice for mulch and biomass operations.
