This Kubota Workshop Manual covers the U35-4 mini-excavator across 514 pages, with the machine built around the D1703-M-DI-E4 diesel engine.
It details the machine body and undercarriage, the hydraulic system (pump, control valve, swivel and travel motors, cylinders, and pilot valves), the electrical system with its circuit diagrams and meter panel, and the cab with air conditioning and wiper. For each you get structure and function, troubleshooting, servicing specifications, and tightening torques. Engine internals are handled in a separate Kubota D1703 manual, which this book points to.
The manual downloads as a searchable, bookmarked PDF, so you can jump straight to the Hydraulic, Electrical, or Cabin section on a phone, tablet, or shop computer and print only the pages the repair calls for.
