Operate in tight areas and have little worry of potential damage with the minimum tail swing and independent center swing-boom. Rapid machine positioning and simultaneous moves of the swing boom and house are accomplished via the foot pedal swing-boom control. The small overhang on the CX55B increases the machine stability and performance. Backfilling is provided by the hydraulically-controlled backfill blade. For quicker backfilling of trenches, an optional angle blade is available. Surface damage is kept to a minimum due to the standard, durable rubber tracks while optional steel tracks provide even greater protection.

Fuel Efficiency

The Yanmar engine is powered to match the performance of the CX55B. This engine meets the current Tier 4 Interim environmental standards while consuming less fuel. CASE Mini Excavators also feature a one touch deceleration to minimize fuel usage while not in operation. Finally, the integrated-flow pump system (IFPS) efficiently manages the pump flow during operation to maximize the use of engine power and increase the fuel efficiency.

Comfort and Visibility

While operating the CX55B, the spacious four post canopy provides exceptional visibility to all areas. For operators working in inclement weather, an available enclosed cab with heat or with heat and air conditioning are available options. Responsive performance and low fatigue are delivered through the smooth, intuitive pilot controls. A standard pattern selector allows operators to choose their control pattern preference for optimum productivity.


Get service and diagnostics done quickly and easily with a one-piece, swing-out side access panel. Grouped hydraulics and rear engine access provide the ability to do daily checks in no time at all.
