This is the factory parts catalog for the Kubota B1550D, the 4WD version of Kubota's B1550 compact diesel tractor produced from 1988 to 1997. Its 302 pages present each assembly as an exploded diagram tied to Kubota part numbers, reference callouts, quantities, and serial number ranges so you order the exact component for your machine.
Coverage runs system by system across the engine, fuel, cooling, and electrical groups, then through the clutch, transmission, rear axle, brakes, and the four wheel drive front axle with its bi-speed turn hardware. Steering, hydraulics, PTO, and wheel options are all diagrammed.
Use it to trace a worn part on the picture page, read off its number, and hand that to your dealer. It is a parts reference for identifying components, not a step by step repair manual.
Complete the set for your B1550D
