I kept the cardboard sleeve from the John Deere belt I purchased from the John Deere dealership. It is #158130 as you mentioned in your response. I also viewed the video link you attached, mine is very different from the snowblower in the video, but the basics are the same. I'm assuming I have an older model. I really appreciate your responses.
The belt is still 6" too long and never actually gets tight enough to blow snow. Any other advise?
As I see it, I can either find a belt that actually works or purchase a separate snowblower.
