tiggercl 28 #1 Posted October 15, 2011 Hi Chaps, When did the mule drive units for the 520H 60" decks change from spring loaded to being simple (no spring, less bits, more welds)? I am having difficulty locating a schematic/parts manual for the simple mule drive. Cheers, Paul Share this post Link to post Share on other sites
scifi4all 6 #2 Posted October 17, 2011 I ran into this issue with an older mule drive. It has replaceable bearings instead of replaceable pulleys. I finally noticed that the parts diagrams for the mower decks from the same year had a parts layout for the Mule Drive. Might be the same for your mule drive. Hope this helps. :thumbs2: Share this post Link to post Share on other sites
