Kubota mower deck

[TSY50]

I'm new to this forum and had a question about mower deck compatibility. I have a Kubota B1750 with an RC54-B mower deck attachment, which has been repaired twice in the past year. It has become hard to find parts for it and recently on a local posting site an RCK54-22BX was available for $400 (in good condition). Does anyone know if the RCK54-22BX deck will fit the B1750? Thanks.
