Ed Kennell 38,330 #2 Posted October 25 There are several 42" SD deck models. Do a search for your deck in the deck manuals section. You will find the idler pulley part number. Share this post Link to post Share on other sites

Lee1977 6,682 #4 Posted October 27 If it has just one flat idler pulley I believe it's 3 3/4" diameter on the out side flange. Would be best to remove it and measure before buying and after market idler. My 42" side discharge deck Is on a 312-8 and not easy to get too right now, and its been a couple of years since I worked on that deck. . Share this post Link to post Share on other sites
