I just wouldn't have anything else to use for my lawns. One thing I have noticed, having all vintages of LawnBoy. The earlier ones were quieter, with larger under-deck mufflers of aluminum, as time went on they made a switch to steel mufflers, and at last, very flimsy steel under-deck mufflers (except the 6.5 hp Duraforce with above deck muffler), and they got louder, due to flimsy steel mufflers.
