As i normally only collect walk-behind tractor i need some info on this model of Bolens. I found one for sale, but it has a cylinder head problem. Not sure the details of this yet. Owner says it a hydro, and has hydrolics, and the deck lift is also. Tractor look pretty clean other than the head problem. Is this tractor worth spending any money on? Are heads hard to find. I beleive he told me it was over haed valve? Would there be any other engine that would fit into it easy? Like i said dont know much about this type of tractor, so any input would be good.
