The Kubota U35S, U35-3S, and U45-3S Excavators are compact, zero-tail swing machines engineered for productivity, durability, and operator safety in confined and mid-sized job sites. Built with Kubota’s reliable diesel engines and advanced hydraulics, these models deliver the balance of power, maneuverability, and control required for construction, utilities, and landscaping projects.
The U35S/U35-3S models are equipped with a net engine output of around 28 hp and an operating weight of approximately 3.7 tonnes, with a maximum digging depth of about 3.14 meters. With an overall width of around 1.73 meters, they provide compact access and stability, while auxiliary hydraulic flow of up to 20.6 GPM ensures efficient operation of various attachments. The U45-3S is a larger machine, powered by a 42 hp Kubota diesel engine, with an operating weight of about 5.3 tonnes and an overall width of nearly 1.95 meters. It provides greater lifting capacity and hydraulic flow (up to 32 GPM), making it suitable for heavier excavation and utility projects.
The workshop repair manual covers comprehensive servicing of all three models, including safety and general maintenance, detailed engine specifications, hydraulic pump and valve systems, travel and swing motors, control systems, and electrical diagnostics. It provides wiring and hydraulic schematics, torque specifications, lubrication intervals, troubleshooting charts, and full disassembly/reassembly procedures. Special coverage includes operator controls, cab features, and servicing of zero-tail swing components to maintain peak reliability and efficiency.
