Just last wk. bought an old Snapper Riding mower now I'm trying to replace the belt that turns the cutting blade. I've bought the same replacement belt but it has too much play in it. I took it back to the store where they sell Snappers and parts and they tell me it's the correct belt but it needs to be adjusted. Where is the spot where I make the adjustment. Yes, it is the correct belt.
