nylyon-(Admin) 7,291 #1 Posted June 4, 2022 While mowing the back yard I went from second to reverse and the tractor wouldn’t move. Turns out that belt came off of the engine pulley, put it back on and went back to work. Anyone have that happen before? 1995 Onan 416-8 1 Share this post Link to post Share on other sites

peter lena 8,634 #10 Posted June 5, 2022 @nylyon, would also go over a detailed lubrication related linkage verification , make the rust run out , my experience with sealed bearings is lube failure , if you are luckey enough to have wide rubber side shields , clean out the " grease " and use lucas x-tra heavy duty chassis grease , 560 deg , will not fail or whine . only an idea , greasy , pete 1 Share this post Link to post Share on other sites
