Finally got my letter from Kubota. Leak got so bad I had to put just enough diesel in the tank to mow yard. The tractor would sputter if I didn't put diesel in it each week, because it would all leak out. Dealer installing tank now. He still was unaware of hitch problem. I printed out the diagrams from this site. He said the BX wasn't meant to hook up to everything. He said it would hook up to all Kubota equipment. The only thing he found that it would not hook up to was a 4 FT. rear mounted mower. The dealer is going to look into fixing the problem. I told him that as long as he honored my request to fix it, if in the future it became a problem, then I would be satisfied. I was assured that would be the case. He may or may not fix the hitch problem along with the secondary tank replacement. I haven't had a problem hooking up equipment as of yet, so I left it up to him.
