After an ice storm hit I started my loader and it seemed to run rough then I could smell burning rubber. So I shut it off waited a little while (thinking a pulley or something was froze} then started back up no more smell or smoke but runs rough (like a bald spot on a belt) Large belt runs smooth smaller belt at top runs rough w/a heavy spring tenioner> Is that normal? Is there a fan belt? where is it all I see are the 2 belts and the top one runs what looks like a pump???
