Bought an 88 ran alright, a nice looking tractor, side curtains good, nice paint , cost $1800, not a bad price.
Let it set, motor stuck, tore it down, it all went down hill form there. Found a crack in the block--$600, crank could not be turned--$250 for crank, had to get new pistons and rings--$375, head had to be re-worked with new seats--$250, gasket set, 1 rod, rod bearings, throw out bearing,and valves along with other things I can't remember how much they cost. Also cost $600 for mechanic to do the labor which was more than reasonable. As it has been suggested, may be a lot better off financially to find a good one to begin with.
