Looking up a seal kit for your Kubota LA272 loader? This 32-page parts catalog breaks the tractor down to individual fasteners across exploded-view sections, from main frame hardware to full hydraulic hose routing. Separate parts lists cover both the 3-position and 4-position control valve kits, alongside component breakdowns for the boom and bucket cylinders. Each cylinder section splits out tube, rod, head, piston, and Kit Seal as individual line items, so you order only what failed instead of the whole assembly. The control valve sections run just as deep: Cap-Spool, Kit Detent Float, Assy Relief Valve, and Kit Load Check all carry their own reference numbers. No more squinting at part numbers on a blurry dealer fax. Bookmarked by assembly and searchable by keyword, you can jump to the boom section, confirm a number, and place the order without leaving your screen.
