(Please let me know if im in the wrong forum) I am looking at a case 444 probly a late 60's or early 70's model. It has a 14hp Kohler and needs a new head gasket. I do not know if the mowing deck is a standard piece but I like the fact that the deck if very well built. It comes with a hydralic roto tiller. Is there anything I should know before diving in and buying?
