The used Komatsu PC55MR is a pre-owned mini excavator that combines the renowned durability of Komatsu’s engineering with the cost-effectiveness of a secondhand machine, making it a smart choice for contractors, small businesses, and property owners seeking reliable performance without the premium of a new unit. Designed to thrive in confined spaces, this model retains all the core features that made the PC55MR a popular choice in landscaping, residential construction, and utility work, even after prior use.

Product Overview
A used Komatsu PC55MR typically has an operating weight between 5,500 and 5,800 kg, depending on its attachments and maintenance history. Its compact dimensions—approximately 1.9 meters wide and 2.5 meters tall—remain a key asset, allowing it to navigate narrow pathways, backyard job sites, and urban areas where larger equipment can’t fit. With a short tail swing radius, it excels at working close to structures or obstacles, reducing the risk of damage during operation. Many pre-owned units come with low to moderate operating hours, ensuring years of productive use when properly maintained.

Key Features (Retained in Used Models)

Engine Performance: Powered by the reliable Komatsu 4D88E-6 diesel engine, used PC55MR units maintain around 40 horsepower (29.8 kW), delivering consistent power for digging, lifting, and grading tasks. The engine’s fuel efficiency remains a standout feature, keeping operational costs low even with extended use.
Hydraulic System: The load-sensing hydraulic system, a hallmark of the PC55MR, remains responsive in pre-owned models, ensuring smooth, precise control of the boom, arm, and attachments. This system minimizes energy waste, contributing to the machine’s efficiency.
Operator-Focused Design: The ergonomic cabin, with its comfortable seating, intuitive controls, and excellent visibility, remains intact in used units. Many models include features like adjustable seats and easy-to-reach levers, reducing operator fatigue during long shifts.
Attachment Versatility: Like new units, used PC55MR excavators are compatible with a range of attachments—buckets, augers, breakers, and grapples—making them adaptable to tasks from trench digging to debris removal.
Durable Construction: Built with high-strength steel in critical areas (boom, arm, undercarriage), used PC55MRs retain their structural integrity, standing up to heavy use and rough terrain when properly maintained.

Advantages of Buying Used

Cost Savings: Purchasing a used PC55MR significantly lowers upfront investment compared to a new model, making it accessible for small businesses or those expanding their fleet on a budget.
Proven Reliability: Komatsu’s reputation for durability means even pre-owned PC55MRs have a track record of consistent performance, reducing the risk of unexpected breakdowns.
Easy Maintenance: With a global network of Komatsu dealers, parts and service for used units are readily available, ensuring minimal downtime for repairs or upkeep.
Depreciation Benefits: New equipment depreciates rapidly, but used PC55MRs hold their value well, offering better long-term returns if resold.
Ideal for New Operators: The PC55MR’s user-friendly design makes used models a great choice for novice operators, allowing them to build skills without the pressure of operating a brand-new machine.
