I ordered a belt for my Simplicity 48" mower deck, it was shipped quickly and the price was less than at other suppliers. When I went to install the belt, I discovered it was the wrong type. Simplicity had re-used the part number for a later model belt. I emailed V-Belt Guys to see if they could resolve the issue for me. They responded quickly by phone and several emails. I did some measurements, they found the right belt and sent it out immediately free of charge. Bobbie was my contact at V-Belt Guys and she is the best! Thank you.
