The CR30B and CR35B combination rollers can be used in a variety of applications, such as driveways, small paths, patchworks, or shoulders on roads.

The machines use the high-frequency vibration of the front drum to achieve density targets, and the four pneumatic rear tires manipulate the compacted material, targeting impermeability and mat smoothness. A Kubota 49.6- horsepower engine powers both models. The machines meet Tier 4-F emissions regulations and feature a passive regeneration system that cleans the filters automatically, thereby eliminating the need for the machine to stop or for operator input. An optional auto-idle feature reduces engine speed when controls are inactive for more than 60 seconds. The auto-vibration feature automatically engages vibration when the machine reaches 1.5 mph and disengages when the speed drops below 1.2 mph, for reduced risk of over-compaction. The drum edges are chamfered and rounded to avoid marking the mat while rolling, and a pressurized water spraying system and separate emulsion tank prevent material pick-up. The operator can adjust the water flow rate and emulsion flow rate independently.
