Wishin4a416 2,190 #1 Posted April 7, 2013 I picked up a 42'' rear discharge deck today to replace my 42'' side discharge. Dont have it on yet as I am doing some maintenance on it. Will my old Drive/PTO belt work or are they different size? Share this post Link to post Share on other sites
Lane Ranger 10,853 #2 Posted April 7, 2013 I believe they are different. If you look in the MANUALS section for a 42 side and rear discharge mower deck similar to yours (or by the year) you should get the number you need to purchase one. I have a couple 42 inch decks but I use 36 to mow with. Share this post Link to post Share on other sites
