the OE belt was $60....
And the $60 you spend on that belt will save you the cost of trying everything that doesn't work!
I have heard from too many guys, only Deere Belts fit Deere mowers! Try anything else and you will have problems!
I will tell you JD like to use odd size belts. The widths are usually odd and the lengths are to.
And the width will change how it rides in the pulley, basically changing the length!
Save the headache Bud, get the OEM Belt!
