So my mower with fan deck has been eating belts if anyone has an idea of what I can try... I have replaced every component replaceable on the deck including the PTO, and I do have harsh conditions admittedly but this used to not be an issue in the same circumstances. Pic is of brand new belt after one use! All components turn freely, tension is good but I have never measured, any ideas?
If you look at the picture carefully, you will see the problem. You have pulley alignment problems. I suggest getting the deck out from under the tractor and give it a good going over.

Also check for any burrs, sharp spots on pulleys and file smooth as needed. Use washers to get pulleys as close to level as possible, and or a pry bar slowly. Tensioner pulley arm probably has lots of slop in it too that needs to be addressed. Make sure you have good belt tension and increase it if questionable.
The belt in picture is a $30 aramid fiber from Amazon made in India, the OEM belts are $70 for the fabricated deck. The owners manual states belt needs 30 ft lbs tension but I am not sure how to measure that?

The belts themselves aren't the problem. Other issues are causing the belts to fail..The deck needs to be checked for damage. The pulleys, idlers, spindles, bushings, and tension springs need to be checked. The pulley alignment is way off.
Its obvious that something is eating the inside of the belt, check eng pully for debri's and then all areas where it runs. I agree that pic shows pulley misalignment which maybe is causing it. My guess idlers are loose moving up and down.

A spring scale attached to the idler and a stationary point on the deck with zero as the full slack, zero tension point and then tighten adjustment to 30lb.
My guess is it's not hooked to the belt but to the tensioner idler pulley. Otherwise if there is a specification for the belt it would be amount of deflection of the belt but you can't do that because the tensioner would continually be taking up slack to the limit of the spring. That sort of measurement is for things like a belt between two or more stationary points.

I have the same mower, and had the same problem. It would take 5-20 minutes, I'd smell rubber burning, then it would throw the belt. Changed out the tension spring and it felt like the tension was unchanged from the original. But it immediately stopped having that problem, and that was two years ago.
From the posted picture there is something rubbing the inside of the belt. This caused the damage pictured overheats and destroys the belt. Be sure to check all around the belt for a guide on the wrong side of the belt or a loose parts hanging down an rubbing the belt. If the belt was loose the edges of the belt would be excessively worn and slipping would be a problem.
