About · Komatsu PC50Overview
The Komatsu PC50 is a mini-excavator in the 5-tonne operating weight class, producing 39 hp and equipped with a bucket capacity of 0.076 m3. It sits at the upper boundary of the compact excavator segment, offering a balance between the manoeuvrability of smaller machines and the digging force associated with heavier short-radius equipment. The PC50 is part of Komatsu's established line of compact construction equipment, built to the engineering and quality standards the brand applies across its broader excavator range.
Typical applicationsWhere this machine is used
Machines in the 5-tonne mini-excavator class are commonly deployed in urban civil works, utility installation, landscaping, and site preparation where access is restricted and ground disturbance must be controlled. The PC50's operating weight and bucket size make it suitable for trenching, foundation digging on confined plots, and secondary earthmoving tasks on mixed-size construction sites. It is also used in agricultural groundworks and municipal maintenance operations where a compact footprint is a practical requirement.
Used-market inspectionWhat to check before buying
When inspecting a used PC50 or comparable machine in this class, prioritise a thorough check of the undercarriage, including track wear, sprocket condition, and roller integrity, as these components represent a significant portion of ongoing ownership cost on any 5-tonne excavator. Examine the condition of the boom, arm, and bucket pins and bushings for excessive play, and inspect hydraulic hoses and cylinder seals for leaks or chafing. Request full service records and verify that scheduled maintenance intervals have been observed. Assess cab or canopy condition alongside visibility and control ergonomics, as these affect operator productivity across extended shifts. Confirm that any attachments included in the sale are compatible with the machine's hydraulic flow specifications and that quick-coupler systems are fully operational before purchase.
Current marketPrice position
The Komatsu PC50 is cross-shopped primarily against the Kubota U48 and the Takeuchi TB250, all three occupying the upper compact segment around the 5-tonne mark. The PC50's 5038 kg operating weight positions it marginally above the Kubota U48, which can matter where transport regulations or site access impose strict load limits. The Takeuchi TB250 is a direct size competitor, and buyers typically differentiate on dealer support network, attachment compatibility, and machine history. Within the PC50's own market segment, the factors that move a unit within its price band are accumulated hours, overall mechanical condition, the presence and condition of hydraulic quick-couplers or additional attachments, configuration choices such as blade type or cab versus canopy, and geographic availability relative to service infrastructure.
