Haven't given up yet, and actually things are looking better all the time. I got the rear seal, that actually is in the front replaced. Got the two bolts replaced that I broke off on the field coil, and put on new valve cover gaskets. So now the oil leaks are gone, and the PTO works as it should.

Pulled the carb and gave it a cleaning, and now the damn thing seems to run pretty good. Changed the engine oil and filter, installed a new fuel filter, and fuel line.
I have the tunnel cover off and noticed the lip seal on the front of the hydro is leaking so I ordered a new one today. Should be in by the end of the week, then I'm going to change the HY-TRAN and filter and go from there.
I'm really digging this tractor, and don't want to give up on it yet and punt it down the road. The more I get into it, the more potential I see

And if a re-power is in order later, that wouldn't be the worst for what I have in it so far......
I'll throw in some pictures tomorrow, "looks" way better already
