Mower belt size

[Corncountytractors 0]

It's me again guys, I have a 3416S and I shredded the mower drive belt that goes to the PTO. Can anyone tell me the length of this belt because it shredded so bad I can't tell the length of it? I tried finding the belt reference but I couldn't find it. Any help would be appreciated. Thanks, Bob
