The Kevlar OEM type mower drive and blade belts from V-Belt Guys are very adequate and seem to meet OEM standards for my Bobcat 72" Zero Turn Mower that is a part of Textron. I have found the belts are shipped immediately and delivered by UPS, I believe, surely in very quick delivery time. The belts are very competitively prices low cost with a minimal shipping cost per order. I have referred V-Belt Guys to many of my extensive Contacts as a referral if great supply source.
