The belt came off the drive shaft pulley on my 54” mower deck. The pulley is so close to a piece of metal that I can’t manually get it back on. I don’t know how it came off without being cut. Thepulley on the mmm drive shaft trans is right up to a metal part that I could not squeeze it thru to place back on pulley and try and finish mowing. Would appreciate any one who experienced this.
