I've got two Kub HST's... A Grand L (purchased on 2002, now at 1000 hours), and a BX (purchased in 2005, now at 600 hours). The L has been nearly perfect in operation (I'll say 9.5). The BX I'd have to knock back a bit (say 8.5), only because it has a mechanical actuated control for the pedal instead of the servo-operated one as on the L. Doesn't have the same flawless return to neutral action of the larger tractor. Never been a problem, but it requires a bit more attention when you're using it.
No mechanical problems with either unit; they work now exactly as when new. We do our own maintenance... changing the HST fluid is costly but not difficult.
