I have a 1863 with 54" deck..I put a set (3) of the Gator mulching blades on it and they work great. Got em from "mowproducts.com
I can cut some pretty high grass and they do a great job,don't even leave any grass clumps or trails.and from the look of the blades they are high lift. /forums/images/graemlins/smile.gif
