The people at V Belt Were very easy to work with as well as informative In my experience.Priced very competitively with a very large inventory of belts ready to ship.The belts arrived very quickly and I put them to work.I like Kevlar belts with their superior strength and endurance.These 4 5/8 belts are on a 8ft heavy duty finishing mower and in heavy conditions makes my 55hp tractor set up and take notice.S far so good.Thank You.
