Husqvarna YTH1842 deck belt ruined

[cbr7380]

bought a deck belt for a YTH1842 model # 223810 ripped,not all the way into but ruined it nonetheless a few minutes after I installed it and mowed around five minutes. I might not have ran the belt through the two hook guides on each side of the front near the front pulley. Do you think that was the culprit? TIA

Here is a video that may help you. It is best to pull the deck away from under the mower to work on it.
