The design incorporates a 690 hp (intermittent-rated), V-12 turbocharged/aftercooled diesel engine to power a 96-inch-wide by 20-inch-deep cutting rotor, making it a true, high-horsepower deep-cutting heavyweight.
Perhaps the most significant of several innovative features is a two-frame design that allows the WR 2500 to retain the very important "floating hood" concept, which allows an expanded volume of material to pass freely through the process without creating a "friction brake" effect on the cutter and cutter drive components.
Material size is controlled by using hydraulically adjustable, manganese-lined breaker bars that can be remotely adjusted by the machine operator to tighten or close down the area between the rotating cutter and the impact bars, a scheme used for decades by the aggregate crushing industry.
Its Type III holder system allows quick and easy replacement of broken or worn-out cutter bit toolholders without the inconvenience and added cost of a cutting torch and welder. Drum rebuilding can be executed in one day by two workers without removal of the cutter.
