The Kubota U55-4 is a classic 5.5-ton zero-tail swing mini hydraulic excavator made by Japan’s Kubota and a top-selling second-hand model worldwide. Its core strengths include a full zero-tail body with side-shift boom, fuel-efficient low-noise original V2607 engine, smooth and precise three-pump hydraulic system, and a low-center-of-gravity highly stable chassis. It is widely applied to construction tasks in confined spaces, such as old residential community renovation, municipal pipeline trenching, landscaping, indoor demolition, farm excavation, roadside ditch digging, small-scale rock crushing and courtyard infrastructure work. Its tail never protrudes beyond the tracks during full swing, and the side-shift boom eliminates frequent repositioning when working along wall corners, fences and basements, avoiding scratches on buildings.Dual independent hydraulic breaker lines are pre-installed at the factory, allowing quick fitting of breakers, grapples, rippers and augers for multi-scenario earthmoving and rock-breaking operations. The self-developed Kubota V2607 direct-injection engine boasts an ultra-low failure rate with low noise and vibration, maintaining stable long-term operation in high-temperature, high-altitude and dusty construction sites. Kubota’s global comprehensive spare parts network ensures abundant readily available wear parts at low maintenance costs, making it the preferred cost-effective 5-ton-class mini excavator for overseas landscapers, farmers and small municipal contractors.
