About the Product
Product Features
Available in 36”, 48”, 60” inch cutting widths, the HDF’s heavy flail hammer tooling, bent axis piston 80cc or 107cc motor options, and 20” inch drum diameter offers a fast and heavy-duty mulching and mastication, with added forgiveness on your tooling in the instance of operator errors or mishaps due to unpredictable terrain with 4.4 lbs. carbide kit blades that can be kicked back. Reinforced and replaceable wear shoes, and the extra robust boxed-in construction, heavily utilizing 100,000 PSI steel, means you can mulch each tree straight to the ground as fast as the job requires, and better process the mulch on the ground to as fine as the job requires. The easy-to-remove panels to thoughtful service areas means faster maintenance and maximum up time. Some notable application types for this attachment are right-of-way maintenance, industrial site preparation/mastication, and rural property preparation/maintenance.
