Why does the belt on the tension arm ride at the very top of the pulley. Nothing has changed on my deck since bought it except change belts,tension bearings and a idler pulley. I have had the mower for about 8 yrs. The reason I have broke a few belts is that I cut along the road for about 1 1/2 miles picking up sticks. I just put one belt on and after about an hour the belt broke in to. But i have noticed that the tension army pulley is riding that the top which makes it pull slightly up from the blade pulley. I'm kinda stumped on what the problem is.
