I bought a snowblower for my MF7 and it had a belt on it that was in okay shape but, since I really don't want to have to replace a belt mid season, I bought a new one. It's a 48X920 Dayco belt that seems WAY too long. I saw a post by olcowhand that the 720 blower takes a MF#1037585M1 belt. I typed that in to search and I found a site that said it's a .531 X 54..27in Outside Circumference. My belt is a 48" belt. Something doesn't fit. I'd like to know how to route the belt and if I need to buy the different length belt? Thanks for any info!!!
