I recently purchased a very "lightly" used 400 hour B7500 from a family friend. It came with a 302 loader and a 50" rototiller. I would like to put a mid mount mower on it to mow my yard. I know what decks Kubota "says" will fit but I found a new in the crate RCK60B-75B deck that I believe is intended for use on a B7510? My question is will this deck be a direct fit on my 7500 or is the mounting the same? Thanks in advance for your help.
