Part of the Kubota Parts Manuals.
This is the factory parts catalog for the Kubota L4400DT, a four-wheel-drive utility diesel tractor. Its 315 pages pair exploded component diagrams with Kubota part numbers, letting you pin down the exact piece you need before ordering rather than guessing from a worn original.
The catalog covers the whole machine: crankcase, cylinder head, piston and crankshaft, injection pump and governor, cooling, the alternator, starter, battery, switches and wiring, clutch and transmission, PTO, hydraulics, front and rear axles, and steering. Every part carries a quantity, serial-number range and interchangeability marks so you can confirm a replacement fits your build.
Owners and mechanics use it to match numbers to a serial plate, order gaskets and wear items in one pass, and verify supersessions. Delivered as a searchable, printable PDF, it works equally well on a shop computer or a phone at the machine.
