Part of the Kubota Repair Manuals.
This is the factory workshop manual for the Kubota LA344AU front loader, supplied as a 94-page PDF you download and keep for reference. It covers the LA344AU loader that mounts to compact Kubota tractors, with a net weight of about 180 kg and a maximum hydraulic pressure of 12.8 MPa.
The manual is organized into the loader information and safety pages, a general section covering identification, lubrication, tightening torques, and maintenance intervals, and a full Front Loader section detailing the hydraulic circuit, boom and bucket cylinders, and the quick-attach coupler.
With it you can identify your loader, follow the correct service intervals, torque the main frame and hydraulic fittings to spec, and rebuild the cylinders when they wear. The file has a text layer and bookmarks, so you can search for a part or procedure and print only the pages you need at the workbench.
