My dealer is over an hour away. and none of the parts stores or anything in town sells an equivalant. Is there a website I can order from to buy this belt? The belt number is 483966. Mower number is:SVR48V-691FX. Also when I took the belt off it was so loose I could easily move it by hand. And when I took it off the tensioner spring lay limp and loose against the deck. Is it normal for the spring to be that loose when removing the belt?
