KJINTF the comment about it being a billgoat is so true, we have chains on the rear tires, it goes up hills I thought would be impossible. It would never make it up some of the hills I do without the chains but the chains are mostly for the winter, we have the snow thrower attachment that does the 300 foot driveway in less than 20min. we also have the extra weight attachment in the back to help keep it on the ground, I'll try to get a photo in of it on top of one of the hills it climbs once the fan is back on. $52 for the fan, it should be here in a few days.
I think I may have a leak at the radiator hose connection that may have caused it to over heat. When I first got the tractor I new nothing about it and it was overheating after about 1.5 hrs of running it in the heat, turned out the rad was packed with dirt and the fellow who owned it bent the fins try ing to clean it I guess, I spent hrs. bending them back and cleaning it, and that was the end of that problem.
So I'm suprised that the fan would melt without the engine overheating warning signal coming on, that kinda makes me think it was just the center bolt that came loose. There are 3 other small bolts that are supporting the fan in some way. They have a sleve on them about 1/4 " long. I didn't notice till I took all 3 off but one of the 3 bolts is shorter, does anyone know how to identify where it goes?
