The Kubota U55-4 is a classic Japanese 5.5-ton zero-tail-swing mini excavator. This Tier 3 direct-injection model requires no urea aftertreatment and offers high tolerance for poor-quality diesel, making it suitable for overseas markets including Africa, Southeast Asia and Latin America. Featuring zero-tail design plus boom swing function, its rear end barely extends beyond the track width, delivering outstanding performance when working against walls, in corners and narrow alleys. It is fitted with Kubota’s original load-sensing hydraulic system, providing precise fine control and smooth, gentle combined movements. It is widely used for landscaping, yard renovation, municipal trenching, pipeline laying, orchard work, indoor demolition, small foundation excavation, river silt removal and light breaking jobs. Factory pre-plumbed auxiliary hydraulic lines support quick couplers, compatible with hydraulic breakers, augers and grapples.
