Part of the Kubota Parts Manuals.
This is the Kubota LA272 tractor loader parts catalog, a 32 page illustrated PDF that lays out the loader in its exact factory assemblies. It covers the main frame, brace, boom, the boom and bucket cylinders, the full hydraulic hose and tube circuits, and the control valve in both 3 position and 4 position kits along with the matching control lever.Each section pairs an exploded diagram with a numbered parts list carrying Kubota part numbers, quantities, and serial number ranges. You can trace a reference number on the drawing to the right part, which is useful on a loader with many hoses, couplers, and small hydraulic pieces.Use it to identify hydraulic hoses and couplers, control valve and detent parts, cylinder seal kits, and frame hardware for repairs like weak lift, a blown hose, or an erratic joystick. Accessories and service parts are listed at the back.

Kubota LA272 Common Problems This Manual Covers
Loader loses lifting power
The LA272 loses smoothness or lift even when fluid looks fine, often from internal leakage or a failing hydraulic component in the cylinder and hose circuit. The cylinders and hoses are itemized with part numbers.
Manual Section: Cylinder/Hydraulic Hose p. 6Hydraulic hoses swell or blow
Blown or leaking hoses under load are a reported LA272 fault, often from age, overheating, or a pressure spike. The hoses, couplers, and dust plugs in this circuit are listed for exact replacement.
Manual Section: Hydraulic Hose 1 p. 10Erratic or unresponsive loader control
The loader responds incorrectly or stops moving when the control valve spool wears or a passage is blocked. The 3 position valve kit is diagrammed with its valve, adapters, and fittings.
Manual Section: Control Valve [3-Position Valve Kit] p. 18Boom cylinder drifts or leaks
A boom that settles under load usually means worn seals inside the lift cylinder. The boom cylinder breaks down into tube, rod, head, piston, and seal kit parts for a clean rebuild.
Manual Section: Cylinder (Boom) [Component Parts] p. 28Weak bucket curl
The bucket curls or dumps weakly when the bucket cylinder loses pressure through leaking seals. The bucket cylinder is diagrammed down to its seal parts for service.
Manual Section: Cylinder (Bucket) [Component Parts] p. 30Worn joystick linkage
Loose or vague joystick action develops as the control lever, bushings, and pins wear. The lever assembly is broken out into individual replaceable parts.
Manual Section: Control Lever [3,4-Position Valve Kit] p. 26Frequently Asked Questions

It covers the Kubota LA272 tractor loader. Parts are grouped by assembly with exploded diagrams and Kubota part numbers, so you can identify frame, hydraulic, valve, and cylinder parts for your machine.
Does it cover both control valve kits?
Yes. The catalog includes separate diagrams and parts lists for the 3 position and 4 position control valve kits, so you can identify the correct valve and its components for your loader. p. 18
Can I find the cylinder seal kits?
Yes. The Cylinder (Boom) component parts section breaks the lift cylinder into its tube, rod, head, piston, and seal kit with Kubota part numbers for a rebuild. p. 28
Can I identify the hydraulic hoses and couplers?
Yes. The Hydraulic Hose 1 section lists the hoses, couplers, dust plugs, and sleeves with their part numbers and band codes, so you can match a replacement to the exact fitting. p. 10
