The Kubota U10, U20, U30, and U45 Excavators are part of Kubota’s zero-tail swing and compact excavator range, designed for superior performance in tight working conditions while maintaining the power and durability needed for construction, landscaping, and utility projects. These models provide varying levels of size, weight, and digging depth to meet different site requirements, all built with Kubota’s reliable diesel engines and advanced hydraulic systems.

The U10 is an ultra-compact model weighing approximately 1.2 tonnes, powered by a 10.3 hp Kubota diesel engine. It delivers a digging depth of about 1.8 meters, with a bucket breakout force of 1,060 kgf, making it ideal for confined job sites. The U20 builds on this foundation with greater capacity, while the U30, at roughly 3.3 tonnes with a 27 hp engine, offers a digging depth of 2.9 meters and reach of nearly 5 meters. The U45, a midi excavator, provides significantly greater capability with an operating weight of about 5.4 tonnes, powered by a 42 hp engine, and achieves digging depths up to 3.6 meters and reach of almost 6 meters. Across the lineup, Kubota’s zero-tail swing design ensures excellent maneuverability without compromising digging or lifting power.

The workshop repair manual provides complete coverage of these models, including engine servicing, hydraulic system maintenance, swing and travel motors, control valves, swivel joints, electrical systems, and cab equipment. It also includes detailed wiring and hydraulic schematics, torque specifications, lubrication intervals, troubleshooting procedures, and step-by-step disassembly and reassembly instructions, enabling accurate diagnostics and professional maintenance.
