- Model FP-66 - Diesel Horizontal Grinders



The FP-66 packs high-volume 'Perfect In One Pass' grinding technology into a mid-sized platform. The Rotochopper FP-66 offers many of the same advantages as the B-66 (our largest grinder) with lower horsepower. So you get the time-saving features designed for large-scale wood waste recycling along with lower fuel costs for smaller raw material volumes.
