I've had a lot of experience with Gator blades and recommend them highly. I have them mounted on a total of five different mowing decks. They hold an excellent edge and the mulching function is very effective. I'd give them five stars overall but I must caution you - the blades I purchased are listed as having a 3/4" center hole. In fact they are about .715, so if you are cross-matching the stated size for application on a different machine (I used the Kubota measurements and crossed them to a Wheel Horse deck) be prepared to have to ream out the center hole to get them to fit. Otherwise, a terrific product and Jack's Small Engines is an excellent supplier!
