I've always mulched my leaves into the lawn for fertilizer and while the stock blades on my Gravely HD52 do a good job on cutting grass, it takes a lot of passes over the leaves to get them cut fine enough to go into the lawn. Looking to get something that will mulch them quicker and finer without so many passes. I don't have mulching baffles or a discharge plug on the mower as I mow 2+ acres, and in the spring, it can sometimes get too long to mulch so the regular blades with side discharge is what I use.
