There are a few threads online regarding blet problems with Serars, Husqvarna, John Deer, ayp, etc, etc and other snow blower attachments throwing auger belts or breaking them. I've had the same poblem and had a guy fab a belt guide that seemed to work. Now....... I went to Agri-Fab's Speedepart.com site and saw that they post the belt info thusly : " part # 478846 - belt, 5.8" X 114.24"
( DAYCO) I poked around on the web and found that the Dayco part # is B 111 K . Went to the Dayco site,and they say that it's a Kevlar belt, but 114" long, instead of 114.25". Now I know that .25" shouldn't mean much, especially when a clutch type pulley is involved. I'm just wondering WHY the discrepancy ?? The blet is said to fit quite a number of tractorss/ snowblower attachmentsAs i siad, there a few threads about this online. Seems to me that the OEM could make it easier for everyone. Thnaks for lettting me rave. Have a good 'un !!
