Looking at one he says weak spark pto on back is disconnected low power on hydro lift so are these easy fix or very costly.

Man Dave, that's a pretty tough question to answer. The weak spark could mean it just needs a tune-up. If its just general maintenance to get the ole' girl whipped back into shape, well I would think it wouldn't be to expensive. If the engine is tired and needs to be rebuilt or replaced, now yer' talking a whole different story. The Onan engines are not cheap to rebuild that's fir' sure. Some of the fellers on here have repowered 620/720 Tractors and are quite pleased with them. I believe there are Honda or Briggs repower kits out there in the aftermarket. Depends on how bad you want a 620 or 720 I guess. That's why that's a tough question to answer.....  LOL!
