Parts Compatible with the Kubota BX23D Sub-Compact Tractor

The BX23D is the early-2000s D-suffix variant in Kubota's BX Series sub-compact tractor lineup, a 23 horsepower loader and backhoe combination machine that preceded the current BX23S. It uses the Kubota D905 era 3-cylinder mechanical injection diesel engine with hydrostatic transmission and 4WD. Customers commonly find BX23D units still in active fleet service in residential property maintenance, equestrian, and small-acreage applications.

The BX23D shares many service parts with the BX22D (the 22 HP sibling in the same era) and with the BX25 successor that replaced it in the same loader/backhoe package family. Successor BX23S service parts generally do not cross fully because the BX23S introduced a refreshed engine and updated cab.

Common Replacement Parts for the Kubota BX23D

Fuel system service uses Fuel Filter 12581-43012 as the primary fuel filter for the D905 era engine. Engine electrical service uses Oil Gauge Plug 1G513-36550 and Key 37410-55150.
