After ordering the offered belt for my Hustler X-One with a 60” side discharge deck, I received it quickly however, I was unable to install it no matter what I tried. On a whim, I measured the old belt and found it 3” longer than the new belt available to fit my mower. I called V-Belt Guys, was greeted by a delightful young lady who verified that belts do not stretch and after explaining my dilemma said they stocked a 168” belt and would ship it out immediately at no charge. I just received and installed it with a minimal of effort. What a difference 3” makes. Thank you so much V-Belt Guys.
