About the Product
Product Features
Available in 60” inch cutting width, the HSL’s three familiar tooling options (chipper, beaver or double carbide) on a “FTR” or optional “CPR” drum type, driven by carefully suited 55cc (or 75cc upgraded) bent axis variable motor, and 17” inch drum diameter offer a range of options, ruggedness, and durability that combine for a forestry-style mulching experience unrivalled by other stand flow options. The HSL maintains Promac’s renowned durability by featuring 100,000 PSI steel throughout its frame with reinforced, replaceable wear shoes. The easy-to-remove panels to thoughtful service areas means faster maintenance and maximum up time. Some notable application types for this attachment are rural property preparation/maintenance, small forest conservation, and suburban property preparation/maintenance.
