This is the factory parts catalog for the Kubota B3030HSD compact diesel tractor. It lays out every assembly on the machine as an exploded diagram paired with Kubota part numbers, quantities, and serial-number ranges, covering the engine, fuel and cooling systems, electrical wiring, clutch, hydrostatic transmission, rear and front axles, brakes, steering, and hydraulics.
With 323 pages of illustrated part breakdowns, you can identify the exact component you need before you order, match superseded numbers using the interchangeability notes, and confirm a part fits your serial range. That makes it the reference to keep alongside a repair when you are pulling apart the HST, replacing a fuel shutoff solenoid, or sourcing gaskets and seals.
Delivered as a downloadable PDF you can read on a phone, tablet, or computer, or print the pages you need for the shop bench.
