"Further, its unique rotor design allows the operator to change the cutter head size on the rotor instead being committed to just one size," Chocholko says. "One VIZ rotor can accommodate cutters as small as 1x1-inch for an output of one-fourth-inch particle size, and as large as 3x3 inches for bulky item size reduction such as bale-breaking."
