Your blades get an A+++++ on annual ryegrass. I grow a lot of it in Pinehurst during the cool season and it's never looked better than it has since I started using your blades. One of the biggest advantages to using your blades on annual ryegrass is the fact that the clippings don't seem to stick as much to the blade and the deck. Saves lots of time! I haven't used a better mowing blade. Good luck. New River Gardens, Inc. This is a quote from one of our customers.
