Anyone have problems les with a 2305 mower deck? I never had any problems. Then I cleaned it and greased it for the season now the belt gets thrown every time I turn on the pto. The belt is only slightly worn starting to fray a little. Is there anything else it could be from cleaning is or does my belt just need to be replaced. All of the pulleys seem tight with no to very little play. With the exception of the idler pulley. The arm will move up and down slightly but seems like it is tight on the busing. All bolts and pulleys are tight. Nothing seems bent.
