I've been raking them onto a big tarp, then dragging it into the woods to dump the leaves. I hadn't really thought about mulching leaves into the soil because I thought the leaves would be too acidic. I bought a 1042 earlier this year that has a deck with the plug, and mulching blades, so maybe I'll give it shot. Either that, or fill the yard up with Cubs so I don't need to worry about the damn grass!
