I have a 250 series mower deck, 37", that's in need of parts. I'm told that the parts are discontinued and not available. Several years ago, you guys helped me out when I need to replace the transmission in my tractor. 252H. You were a big help. So, once again I'm turning to you for help. I have a mower deck which needs the Jack Shaft bearing and pulleys replaced. The serial number of the mower deck is: 0537SK01-80985. Where can I get parts or find a used mower deck for my beloved tractor? Any help will be appreciated.
