I do mulch through both here. But there is a limit to how much you can do effectively at one time. Especially when the leaves are wet and matted down. I did rake off the walnuts around the woodpile-the neighbors pine trees are right there,...:rolleyes: Partly cause they kill the grass, but more so I don't bust an ankle walking on them. The ones down back I mow over. Makes quite a racket when the blades hit them. LOL
