For what its worth, I bought this Super Dexta a year and a half ago for $900.
Ended up putting a new clutch in it. The trans seals were leaking and had it soaked with oil. It had a loader at one time and the clutch was pretty well worn out anyway. Also did the head gasket. Still have a couple other oil leaks to tend to, but overall its a nice tractor. Had no problems finding parts so far.
