Did a little digging and found some ideas from "other tractor sites" (names won't be mentioned

There is a product made by ProVantage that adds scoop wings onto their product, but others have had good luck installing them on other brands/colors of blades. I bet these would work on our blades, but who's willing to be the test dummy
