Need the right factory part number before you call the dealer? That's the single job these 581 pages do for the Kubota L3130DT, L3130GST, and L3130HST. Every major assembly gets an exploded-view diagram beside its numbered parts list, from the crankcase and piston-crankshaft group down to the HST unit's piston, regulator, and rotary component sets. Kubota's interchangeability symbols sit in each section, so you can tell at a glance whether a listed part crosses to your DT, GST, or HST variant. The electrical section splits fuse ratings by circuit (5A through 40A) and lists switch assemblies separately for each transmission, pointing you to the exact harness or relay number you're after. Three variants, one catalog, so cross-checking takes seconds. Bookmarked by system and searchable by keyword, it pulls up fast on a tablet to confirm the number and order it once.

Kubota L3130DT, L3130GST, L3130HST Common Problems This Manual Covers
Kubota L3130HST loses drive power and struggles under heavy load with extremely dirty hydraulic fluid. p. 358
Check the hydraulic oil line inlet diagrams on page 358. Locate the 0.535 kgf oil filter assembly and its mounting bracket. Cross-reference the filter cartridge part numbers for your specific HST type serial number before ordering a replacement to ensure proper fluid flow.
Manual Section: Hydraulic Oil Line(Inlet) [Hst Type]Engine cranks but won't start, or catches only intermittently, when fuel delivery falls short. p. 40
Trace the engine stop lever components on the page 40 diagram. The 0.29 kgf fuel shutoff solenoid and its mounting hardware are called out there; confirm the solenoid assembly's part number in the matching parts list so it fits your engine configuration.
Manual Section: Engine Stop LeverTractor engine stalls unexpectedly or safety interlocks shut the machine down during standard field operation. p. 109
Inspect the switch and relay diagrams on page 109. The 0.07 kgf relay assembly sits with its connector block; read off the component reference numbers and match them against the parts index so the replacement relay fits your safety interlock circuit.
Manual Section: Switch/Relay [Rops Type]Diesel runs down on power and stalls without warning once fuel flow gets choked off. p. 84
Open to the fuel filter breakdown on page 84. Note the 0.59 kgf filter element and its sealing O-rings, then look up their part numbers in the table to get the right replacement element and bring fuel flow back.

Document Quality
This document is a hybrid PDF, featuring native digital text for part lists and scanned images for diagrams. You can search and copy the full text, as an OCR layer is present and accurate across all pages. The text on the part list pages is crisp and easy to read. Diagrams and illustrations are scanned raster images, which are generally clear and readable, though they will pixelate at high zoom levels. Some minor scan artifacts, faint lines, or slight page skew are visible on diagram pages, but these do not hinder readability. There are no blank pages, though some pages are dedicated to 'OLD PARTS' diagrams.
