Well first of all make sure you have it around all the proper pulleys,
2nd be sure you have the right belt. Plus, how loose is i t now?
And do you have the model number?
That's about 1" too much.
IT'S THE ORIGINAL BELT, I JUST NEED TO TIGHTEN IT UP , HOW ?Not sure, either you got the wrong belt or they put the belt in the wrong size packaging.
Is it a Cub/MTD belt?
Well, as far as i know you can't tighten a deck belt up. Just replace it with a new one if it's the original I'm sure it's stretched out.
I'm 70 years old and live on a fixed income aside from being disabled, I guess my lawn will not get Mowed this year,
Thank you for your help, much appreciated
