I recently purchased a B7510. I want to get a Mid-Mount Mower for it. I didn't buy the tractor to mow, but it would be nice. I called the dealer. He said one was $2400 if they still had any (old machine, mowers not being made new anymore). From what I can tell it takes a RCK60-24B. I've found a used RCK54-22BX available for far less than $2400. Anyone know how much work it would be to make it fit (assuming I could). Thanks.
