RC72-27B(A) covers the model spellings RC72-27B and RC72-27BA. These are mower-deck applications, not a fit claim for every attachment used on a B3200 or B7800 tractor.

Deck serial numbers and gearbox versions

Kubota lists component changes within RC72-27B(A): housing at serial 10480, bevel-gear shaft at 11717 and breather at 13647. RC72-30B has a breather change at serial 11223. These are component-change notes, not a serial cutoff for the complete K5791-33100 assembly. Compare your original gearbox and have the deck serial number ready if the version is unclear.

The referenced Kubota diagrams are for U.S. models. For equipment from another market, ask us to check your deck tag and original gearbox before ordering.
