MR 4800 Deck

[Anonymous Poster]

I have a MR 4800 48" mower deck - the mechanicals are fine but the steel stamped housing has been bent too many times an is a mess. This was sold with the B-6100 tractor 1982 vintage. I think the deck was originally a kubota design starting in 1974+.
Any one have an old deck with a good housing they want to sell? Or any suggestions as to what I can do. I am told there is no new deck that will work as belly mower on this unit. Is this true? Seems strange!
