Part of the Kubota Parts Manuals.
This is the Kubota LA300 front loader parts catalog, a 25 page illustrated PDF that breaks the loader down into its exact factory assemblies. It covers the main frame, boom, hydraulic oil pressure circuits, the control valve, and the boom and bucket cylinders, plus the optional front guard and service accessories.
Each section pairs an exploded diagram with a numbered parts list carrying Kubota part numbers, quantities, and serial number ranges. Both boom and bucket cylinder groups are split by serial number, so you can order the exact cylinder parts that fit your machine.
Use it to identify cylinder seal kits, hoses, fittings, pins, and frame hardware for repairs like a boom that will not raise, a loader that drifts down, or a body stuck on the subframe. Every part traces back from the diagram to a specific reference number and Kubota part number.
