Not sure if you are talking about a JD 500 series tractor- but if you are nothing could be further from the truth. A new X570/580/590 will give 20/30 years of hard use if properly maintainedBack in the day they built stuff meant to be maintained that you could pass on to your grand children. Now they build stuff meant to be replaced every 5 years or so. Push a throw away garden tractor past average homeowner use and you won't get that 5 years out of it...
To still.try.decide - yes if you go with X570, the johnny Products electric sleeve hitch is way to go- with X580 or X590 JD sells hydraulic sleeve hitch for them - and that would be preferred way to go on them- faster response than electric hitch
