Part of the Kubota Parts Manuals.
Order the right part the first time. This Kubota L4400DT parts catalog runs to 315 pages of exploded views, with crankcase, injection pump, rear differential, steering cylinder, and 3-point linkage each broken down into a full parts list of reference numbers, quantities, and interchange codes. The drivetrain gets thirty pages on its own, covering the main shaft, countershaft, PTO clutch, and all three range-shift fork assemblies separately. Need the battery? It's the 80D26R. Checking a circuit? Fuse ratings run from 5A to 40A, listed by position. Replacing a headlight? Both old-type and new-type bulb numbers are spelled out. A wrong part means another round of shipping and downtime, so the catalog is bookmarked and keyword-searchable: pick the system, find the number, place the order.
