Part of the Kubota Parts Manuals.
This Kubota RC72-30B parts catalog is the factory illustrated parts list for the RC72-30B mid-mount mower deck. It provides exploded diagrams and Kubota part numbers for the universal joint, bevel gear case, pulley holder, blade, tension pulley, mower deck, front gauge wheel, rear wheel, discharge cover, linkage, lift linkage, lift arm, and stopper assemblies.
Use it to match a worn component to its exact Kubota part number, verify quantities, and read the interchangeability and serial-number notes before you order. Each section pairs a numbered drawing with its parts table, so you can trace a part from the diagram straight to the order sheet.
This is a parts reference, not a step-by-step repair manual. It suits owners and independent mechanics servicing the deck drivetrain, blade spindle, belt drive, and the wheel and lift linkage wear points on the RC72-30B and RC72-30BB.
