Reduce price (was $425,000)

2017 Rotochopper B66L with 8,700 frame hours but only 700 hours on a CAT-certified rebuilt engine — that’s a major reset on the most expensive component, and it still has warranty remaining. This is a high-production grinder with fresh engine life where it counts.

Who This Machine Is For

• Mulch producers — built for consistent, high-volume grind
• Recycling yards — handle wood waste and organic material efficiently
• Land clearing operations — process large volumes of brush and logs
• Contractors running long hours — rebuilt engine reduces risk and downtime
• Operators needing production — 1000HP class grinder for heavy workloads

What It Grinds

• Wood waste — primary application for high-volume grinding
• Logs — handles large feed material with ease
• Brush and green waste — reduces quickly for volume control
• Pallets — processes scrap wood into reusable material

This is not a chipper. It produces ground material, not uniform chips.

Specs in Plain Language

This unit shows 8,700 hours on the frame, but the key detail is the CAT-certified engine rebuild with only 700 hours — and it still has warranty left. That takes a big concern off the table for a machine in this size class.

It’s powered by a 1000HP CAT engine, giving it the power needed for high-production grinding. Machines in this range are built to run all day and handle large volumes without slowing down.

The B66L is known for its grinding system that produces a consistent end product, especially for mulch operations. It is fully operational, but note that the infeed chain may need replacement soon and it will need a couple of teeth, which is normal wear on a grinder.

If you’re comparing options, check out other horizontal grinders or pair it with equipment like trommel screens to separate finished material.
