just joined but have been perusing the site for a few weeks now since I purchased a 1971 cub cadet model 109. Love it. Has a Kohler K301 engine in it so basically got transformed into a model 129. Runs great just needs some clean up. The mule drive belt is quite worn and has started jumping off the mover deck fly wheel. the belt on the unit is 1/2 inch by 81 inch but what I have found is that it is supposed to be a 3/8 inch by 80 inch belt. Would that be why it is jumping off? Look forward to restoring this tank.
