Why it's dragging-?
I was given a Proform 765 Ekg Treadmill. When you turn it on it works great, My brother already replaced the belt. Anyway when my sister-in law gets on it it seems to work fine, but when a person of 185lbs gets on it , it drags and the belt doesn't seem want to move. It sits on a wood floor. Does it need the motor replaced or what?
