Docwheelhorse 2,560 #2 Posted April 3, 2009 Hi--put on a longer belt to make up for the 5" diameter pulley on the engine that the Auto used, 8 speeds use a 4" pulley. The geometry of the belt is wrong and after a bit of use the pulley/belt is heating up and won't release that final little bit to stop. Did you use the belt off of the hydro too? The stock 8 speed belt is Toro # 7374 Good Luck Tony Share this post Link to post Share on other sites
