Problem with throwing belt on 48" Viking


LawnSite Member
East Tennessee
I just replaced the engine to deck belt on my 1996 Viking 48 Hydro with an Exmark OEM belt(303499).Set the proper tension of 1/2" pull at 10lbs force.But everytime I DISENGAGE the blades,it throws the belt.I've tried repositioning the belt guides and nothing seems to help.I know I got the correct belt.I've tried everything I can think of.It also makes a racket when I initially engage the blades,but just fir a second or two.Then it throws the belt every time I try to disengage the blades.Any advice?Thanks!!
