I was not happy with the extremely short life of my belt, I had replaced all pulleys and mower spindles several weeks prior to replacing the 5 year old belt. the old belt was showing signs of normal wear. So I replaced it with your belt, after ten hours of use the belt was shredded so badly I was afraid of it damaging the new replacement parts, so I removed it a put the old belt back on it! I don't know what was wrong with it but the old one is working fine as of now.
