Grind & Color System
Our patented Generation II Colorizer System maximizes quality while minimizing costs by injecting colorant directly into the grinding chamber to produce mulch with the right size, texture, and color.
The B-66 combines high throughput capacity with grinding simplicity for colored mulch, animal bedding, and other products.
The B-66 maximizes your up-time productivity with time-saving features like our patented screen changer and replaceable mount rotor.
No other grinder offers this level of versatility to quickly switch between diverse feedstocks while maintaining precise product control.
Track & Dolly System
It’s the best of both worlds: crawler tracks to navigate your work site, plus a removable dolly to streamline highway transport.
Replaceable Mount Rotor
Simple yet rugged, our patented rotor limits bolt stress from severe impacts and lets operators quickly swap tooth mounts without special tools—just two bolts per mount.
Screen Installation System
Our patented system allows operators to quickly change screens – reducing downtime and enhancing versatility – without needing overhead lifting equipment, fasteners or special tools.
Adjustable Slab Ramp
This patented feature enables the operator to hydraulically raise or lower the height of the cutting anvil relative to the grinding rotor.
