I've installed the mulch kit on my 48" walk behind Gravely, and been very pleased with the cut using the supplied mulching blades. With that said, I am always looking for something better, or a different approach and would appreciate feedback on your experiences with various blades on the Gravely. The blades that came with the deck look just like these Exmark blades. Not having seem the Exmark in person, there may be some difference I can't see. Anyway, just looking for some alternatives. Thanks!!
