High-Volume Grinding Simplified

Our B-66 and B-66 E simplify high-volume grinding with exclusive features that minimize downtime and maximize end product control. For lower volume operations, the FP-66 is uniquely scaled to suit the needs of forestry and tree-care operations by offering an industry-leading combination of portability and efficiency.

KeyKnife Chipper Package

Rotochopper's KeyKnife Chipper Package enables chipping and grinding with a single machine without sacrificing ease of operation and maintenance. A Rotochopper grinder with the KeyKnife Chipper Package can quickly switch from grinding to chipping by swapping the grinder tooth mounts with chipper mounts—no special tools or complicated conversion kits, just two heavy-duty bolts per mount.

Portability & Uptime

Our track and dolly system minimizes transportation and handling costs by combining the time-saving benefits of crawler tracks with the convenience of tires for highway transport. Crawler tracks reduce the hassle and downtime of forwarding raw material to the grinder and re-positioning trailers. The transport dolly eliminates the need for a lowbed trailer. With this system, a Rotochopper grinder goes from highway transport to worksite navigation and grinding in minutes.
