Took off on what was an hour+ drive after what I though was a XL series tractor and deck. Was after the deck more than the tractor. The deck looked good, what I could see in the grass that was grew up around it. Spinals were free and though sounded a little dry. Loaded it up and headed for home. Got home and started checking it over better and found it was not a XL series but a QT series. Model is 1666 and I think it is an Onan engine. Don't ever remember seeing a Kohler with heads like is on this one. Tractor is a little rough but think I can salvage it, seeing as how the deck will not work with any of my XL's. Price was right so no harm done.
