Sales Features

Enhanced Vibratory System

An optimized drum yoke design, more amplitude and the proven Cat® pod-style vibratory system provides enhanced compaction force.

Reliable Power Train

Equipped with a powerful Cat engine and the proven Cat dual-pump propel system, B-Series Vibratory Soil Compactors have the power and traction to provide exceptional performance even in challenging job conditions.

Comfortable Operator’s Environment

The operator’s station on the B-Series vibratory soil compactors has been enhanced to provide greater operator comfort and convenience.

Cat Compaction Control Option

Cat Compaction Control is a compaction measurement solution that improves quality and efficiency by providing information that allows the operator to determine when compaction meets specifications, which eliminates guesswork, reduces the risk of rework and allows the operator to quickly move on to the next job. Cat Compaction Control is factory integrated with the machine, providing greater protection for components. Two separate compaction measurement technologies are available: Compaction Meter Value (CMV) or Machine Drive Power (MDP).

Easy to Service

Service access is simple and convenient on the B-Series vibratory soil compactors. All routine service is conducted from the right side of the machine. The durable one-piece hood tilts forward quickly and easily for exceptional access to the engine and cooling system.
