Model 4100, one of five asphalt rollers in Stone Construction Equipment's WolfPac line, uses 40-inch-wide drums and generates 4,000 pounds of impact per drum. The roller is ideal for driveway and parking-lot applications, as well as for a variety of other confined-space applications. This articulated-frame machine features double-drum drive, an isolated and dedicated hydraulic circuit for eccentrics and steering, plus a pressurized water system with a gravity-feed backup system.
