The only belts I use on my commercial Bobcat zero turn mowers are the blue kevlar belts from V-Belt Guys. The are stronger and last way longer as compared to the OEM belts from the dealers. The dealer deck deck belts is nearly $135 dollars for one and for that price I can buy three belts from V=belts guys for that price and the belts are better in quality all around. As long as I need belts, there is no other place to go but V-belts guys. I have told my competitors in the lawn service industry and they have too started to buy from them.
