I see a lot of cracked blocks that have been fixed where I live,even chunks put back that didn't leak! they use a DC welder reverse polarity and peheat the parts, a good welding shop can do this, them are real good tractors if not the best (my girl says they are the wrong color orange, AC diehard she is) I'd buy it if I was closer and you didn't want it cus Thiers a bunch of em here and people like them to death (as in worked to death) fix or part its a good deal
I think there might be more around here to just not turning up on the for sale listings. We have a dealer about 5 miles from where the Tractor is so I have a source for parts if it works out that way. A big rental place in town has 2 of them he rents out. Has several attachments for them. I rented one once to till my new garden with. Worked great but the pto engagement is in an unhandy place. Hit it with my foot and it would not engage. Didn't know where it was.
