This is the factory parts catalog for the Kubota B6000 compact diesel tractor, supplied as a downloadable PDF. It works through the machine group by group, from the crankcase, camshaft, crankshaft, and injection pump to the transmission, differential, clutch, brakes, steering, oil pressure hydraulics, and the front axle groups for the four wheel drive B6000.
Each group shows an exploded diagram beside a parts table with reference numbers, Kubota part numbers, quantities, serial number ranges, and interchangeability notes, so you can identify the exact component your tractor needs and confirm it fits your serial number before ordering.
Use it to source the right filters, seals, clutch, brake, or electrical parts with genuine Kubota numbers, and to restore or repair an aging B6000 without guessing which part fits your machine.
