Wirtgen America introduces its Rumbler III rumble strip cutting attachment, enhancing its line of rumble strip cutters. The Rumbler III cuts three times as fast as the Rumbler I, introduced in the late 1990s.
The Rumbler III permits fast installation of rumble strips on existing paved shoulders, up to 180 feet per minute. Its standard cutter width is 16 inches, with depth adjustable to one inch.
The Rumbler III features a six-sided rumble wheel with urethane pads and a hydraulic rumble wheel drive. Designed for the W 600 DC milling machine, the Rumbler drum and wheel can be mounted on either the left- or right-hand side of the machine. Wirtgen America can provide custom drum widths if desired.
The Rumbler drum housing was made the width of the tractor, with operator comfort and productivity in mind. And like the Rumbler II, the Rumbler III features a design which permits the cold milling machine to remain stable while the rumble strip cutter moves vertically.
