FEATURES & BENEFITS
Adjustable feed roller
The feed roller can climb up to 50 in (127 cm), helping the machine to crush logs or stumps that need to be rolled, and allowing the operator flexibility for different material inputs.
Low sidewalls
Low sidewalls aid in feeding whole trees and other larger material with less restriction, reducing the need for operator interaction with the material.
Optional Damage Defense system
The optional Damage Defense system reduces the likelihood of certain metal contaminants from entering the hammermill by reacting to the initial contact with the contaminant and reversing the feed system to allow removal of the contaminant.
Optional screen hoist
Change screens easily utilizing the optional screen hoist and the remote control or main machine controls.
Series III hard-faced duplex drum
The Series III hard-faced duplex drum offers durability and convenient maintenance, with the ability to remove and replace single hammers and balance the drum externally.
SmartFeed system
The SmartFeed system monitors engine rpm and adjusts grinding speed for optimal machine performance.
