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.
