I currently have a husqvarna ZTH 6125KOA model no 968999165 and do all the maintenance and upkeep myself and now I am having a problem that I just can't figure out and hope that someone out there has some insite to help,
My mower has a 61 inch deck and the belt tensioner is good and I have a new belt on it and every time I put on the clutch the belt comes off. Looking at the new pulley, it is bigger in width and not like the one I had to take off because of a bad bearing, it has a complete new clutch assembly, also the other pulleys and bearings are in good shape.
If anyone out there has any information that may help it would be greatly appreciated.
Thanks in advance

Probably got the wrong pulley. Changing size will change the amount of tension on the belt, which will cause it to jump off.
