Parts Compatible with the Kubota B2301 Sub-Compact Tractor

The B2301 is a 23 horsepower current production sub-compact tractor in Kubota's B Series, the entry sub-compact below the B2601 in size class. It uses the Kubota D902 era 3-cylinder diesel engine with hydrostatic transmission, 4WD, and the LA340 factory loader option. The B2301HSD-1 designation indicates the gen-1 refresh of the same physical machine. Both the base B2301 and B2301HSD-1 share the chassis, drivetrain, engine, and hydraulics.

The B2301 shares many service parts with the B2601 (the 26 HP sibling in the same B Series sub-compact lineup) and with the BX Series sub-compact tractors that share the D902 engine family.
