Yea, my wife talked about getting me a new seat for Christmas. We'll see if I get it or not. Money has been pretty tight this winter. If not, I'll get one come spring.
I just got mine back in October for my birthday present for myself. So far, I've been prioritizing repairs. The steering was/is first - and the cowl since the steering housing was removed. Next will be the 3PH and all fluids/filters, etc.
Everything else (running wise) is pretty tight. My steering had a full wheel turn of play. And the control for the 3PH doesn't work. The 3PH comes up strong when you start the tractor, but the control doesn't do anything. The only way to lower it is by backing off the rate-of-drop knob until it lowers. I suspect I'll find a disconnected or broken linkage inside when I get to that point.
After that its mostly causmetics. The seat, replacing the faded decals, maybe some new paint, and eventually a new canopy instead of the plywood that was put on top. Who knows, maybe some day I'll try making a cab for it? It will take some thought about what to do between the seat and 3PH though.
