I checked my charger 12 tractors & also checked at partstree,looking at assembly drawings/parts list looking at listings for charger 9-12 & my tractors all have a full length guide rail welded to inside of cover,check that same not missing from cover,without removing cover,from left side of tractor(eng flywheel side)look around battery or between battery/eng confirm rail there,also with parking brake/clutch handle(depending on your point of view)in UP position confirm belt laying on TOP of guide rail and that belt NOT under rail(easy to do,been there done it)if belt under rail this can cause problem you have.
If rail/belt routeing not the problem,remove cover & check that eng/trans pulleys not loose or out of alignment,if pulleys lined up I would suspect previous owner may have changed/replaced eng pulley or linkage parts for idler pulley worn allowing pulley to stay in contact with belt.
