Part of the Kubota Parts Manuals.
This Kubota RCK60-30B parts catalog is the factory illustrated parts list for the RCK60-30B mid-mount mower deck. It gives you exploded diagrams and Kubota part numbers for every assembly on the deck, from the universal joint and bevel gear case through the blade, pulley holder, tension pulley, mower deck shell, gauge wheels, discharge cover, and the lift linkage and lift arm hardware.
Use it to identify the exact replacement part before you order, cross-check reference numbers against the diagram, and confirm quantities and interchangeability by serial number. Each section pairs a numbered drawing with the matching part table, so you can trace a worn component to its Kubota part number without guesswork.
This is a parts reference, not a step-by-step repair procedure. It suits owners and mechanics servicing wear items on the deck drivetrain, blade spindle, and height-adjustment linkage.
