All the problems that I have had to date were minor and quickly resolved by my dealer. Problems: When it was delivered (January), it had a leak in the fuel tank seam. Immediately replaced. Recently I posted resolutions to battery charging and weak brake problems (see thread Kubota Owning - BX 2200 Trouble report after 40 hrs). Quickly responded to by the dealer.
One issue reported to date by several owners (to which I concur) is has how tight the 3-point is.
You have to do some real maneuvering to get some implements attached. Grease the hitch balls up real good! Don't go crazy on implement sizes. For example, a 6' blade may sound nicer to use than a 4', but not when you have to physically angle/re-angle it (drag the implement to reorient) during the installation.
Bottom-line though, no regrets to date. It's has been much more tractor than I expected (always a nice surprise). I don't know how I ever managed to live 45 years without a loader. (Then again, I don't know if my property/trees/house will survive another year with me having one /w3tcompact/icons/wink.gif).
