I have a 5030, which is a slightly larger version of the same tractor.
Itís been a very economical machine to run. The hydraulics are live, but the PTO is not! It does have a built-in overrunning clutch, though.
Accessories like starter, alternator, diesel injection parts are readily available. Major parts are a problem, although I havenít needed any-yet.
The radiator screen needs cleaning regularly or it will overheat.
