BW190AD-4Fitted with 79-inch-wide drums, the BW190AD-4 is a tandem vibratory roller driven by a 131-hp Deutz diesel engine. Slanted drum-support legs and design of the frames enhance visibility. The roller delivers 28,800 pounds of centrifugal force in its low-amplitude/high-frequency (3,600 vpm) setting, and 40,950 pounds in its high-amplitude/low-frequency (2,880 vpm) setting. It can handle jobs from granular bases to Superpave.
