Kubota U55-4 is a classic Japanese 5.5-ton tight-tail mini crawler excavator. The export Tier3 version adopts Kubota original V2607-DI mechanical direct injection engine without urea after-treatment. It features strong fuel tolerance and good adaptability to low-quality diesel, suitable for overseas markets such as Africa, Southeast Asia and Latin America. Equipped with Kubota HMS 3-pump load-sensing hydraulic system, boom, arm and swing get independent oil supply for four-way combined movements. It delivers smooth and precise control, straight travel circuit and auto-shift travel system, balancing power and fine operability. The tight-tail design together with boom offset function makes it suitable for restricted jobsites including wall-side work, narrow alleys, yard renovation, municipal trenching and indoor demolition. Standard dozer blade with float function helps backfilling, grading and machine stabilization. Widely applied for municipal pipe trenching, landscaping, farm water conservancy, foundation excavation, site leveling, light breaking and indoor demolition. The cab has reasonable layout, great visibility and light control levers. Service points are centralized with single-side service cover for easy ground-level maintenance.
