This is the Kubota L2800 and L3400 Workshop Manual, the factory service manual for both compact utility tractors. It covers the L2800 with its D1403-M-E2A diesel and the L3400 with the D1703-MA-E2A, in 2WD and 4WD form, with manual and hydrostatic (HST) transmissions.
The manual runs from tractor identification and maintenance schedules through the engine, clutch, transmission, rear and front axles, brakes, steering, hydraulic system, and full electrical system. Every mechanical section includes troubleshooting, servicing specifications, tightening torques, and step-by-step checking, disassembly, and assembly.
For an owner or independent mechanic this PDF download is the reference for setting clearances, torquing fasteners to factory values, and tracing wiring faults. It is text-searchable and prints cleanly, so you can keep it on a laptop in the shop or run off just the pages you need.
