Part of the Kubota Parts Manuals.
This is the factory Kubota Parts Catalog covering the LA351, LA301, and LA271 front loaders, a 29-page PDF you can download and print. It lists every serviceable part across the main frame, boom, control valve, control lever, and hydraulic system, with the diagrams organized by serial break so early and later machines are both covered. Each assembly pairs an exploded diagram with a numbered parts list, so you can match a component to its exact Kubota part number, quantity, and serial-number range before you order.Use it to identify replacement hydraulic hoses, tubes, quick couplers, boom and bucket cylinder seal kits, loader pins, bushings, and mounting hardware, or to rebuild the control valve and lever. Because the catalog spans three models with serial breaks, some references carry more than one part number, so checking your loader's serial number is important. Whether you are chasing a hydraulic fault or ordering wear parts, this catalog gives you the numbers you need.

Kubota LA351, LA301, LA271 Common Problems This Manual Covers
Loader functions are slow or weak
Boom or bucket functions that move slowly or feel weak often trace to low fluid, air in the lines, a sticking spool, or worn couplers and hoses. The control valve section identifies the valve assembly and its adapters.
Manual Section: Control Valve p. 7Quick coupler leaks or binds
Worn or incompatible quick-release couplers cause hydraulic problems on these loaders, and owners report replacing them to restore function. The cylinder and hose section lists the coupler, dust plug, and sleeve by part number.
Manual Section: Cylinder-Hydraulic Hose p. 17Boom or bucket cylinder drifts down
A cylinder that will not hold position has worn rod or piston seals. The component-parts breakdown lists the tube, rod, head, piston, and seal kit for the boom cylinder rebuild.
Manual Section: Cylinder (Boom) [Component Parts] p. 19Control lever feels sticky or inconsistent
Wear or contamination in the control lever and valve makes operation feel sticky or hard to adjust. The control lever section identifies the lever, bushings, collar, rod, and grip.
Manual Section: Control Lever p. 15Bent or leaking steel hydraulic lines
The steel tubes across the loader can bend or crack and leak. This section lists the four hydraulic tubes with their clamps and hardware for exact replacement.
Manual Section: Hydraulic Tube p. 23Loose loader mounting hardware
Improperly torqued or loose bolts let the frame and linkage shift after maintenance. The main frame parts list gives the hex bolts, washers, connector, and pins with sizes and quantities.
Manual Section: Main Frame p. 3Frequently Asked Questions
Which loaders does this catalog cover?
It covers the Kubota LA351, LA301, and LA271 front loaders in one book, organized by serial break. It is a parts catalog, so it identifies components and Kubota part numbers rather than giving repair procedures.
Can it help me identify the right quick coupler?
Yes. The cylinder and hydraulic hose section shows the coupler and connections, and separate part numbers apply to earlier and later serial numbers, which is the common source of confusion when ordering. p. 17
Does it cover the control valve internals?
It does. A dedicated component-parts section breaks down the valve spool, detent kits, relief valve, load check, and seal kit so you can order the pieces to rebuild the control valve. p. 11
How do I pick the correct part for my model and serial?
Each parts list uses a serial-number (S.No.) column with interchangeability notes across the LA351, LA301, and LA271. Check your loader's model and serial number against the range shown before ordering.
How is this Kubota LA271 Parts Catalog delivered?
A 29-page Parts Catalog in searchable PDF format, ready the moment checkout completes. Open it on a computer, tablet, or phone, with no shipping wait.
Is this Kubota LA271 manual print-friendly?
Yes. Print as many copies as you want, with no restrictions. Plenty of mechanics print just the section they need and take it out to the shop floor.
