I'm considering selling my g1900s with a 60 inch mower deck. It has only 880 hrs on it. The only problem is that one of the drive shaft's u joints snapped. It's the one that connects to the engine. The other end with the little white fan is fine. The tractor is about 20 years old and I have heard that this is a common issue with these series. I think I could replace the whole assembly for $350-400 bucks. I know how to do it but that's an awful lot of money. I would only be able to buy a low end riding mower for what I'm selling it for. The engine runs like new and that's really the only thing wrong with it. I need to be able to mow my lawn but I'm wondering what everyone else thinks. Am I making a mistake?
