hammers , as well as being able to externally balance the drum .
The grinder is equipped with Vermeer SmartFeed and Thrown Object Deflector ( TOD ) technology . SmartFeed optimizes machine performance and production electronically and allows the operator to focus on loading raw product and move finished product about the jobsite . This function stops and reverses material from feeding into the hammermill when the engine ’ s rpm drops below efficient operating range . Vermeer TOD decreases the quantity and distance of thrown objects , which allows the machine to be operated in a smaller “ safe ” work zone . The TOD is hinged and can be raised or lowered with the remote control depending upon grinding applications .
The remote allows the operator to engage the tracks for onsite manoeuvrability and view . Additionally , it allows the operator to change a variety of settings
