           Just one year ago, Simplicity startled the power garden industry with this new look in riding power units.   The Wonder-Boy was new, revolutionary . . . an exciting step forward.   But even then, people saw in it the answer to their lawn needs.

            Today, Wonder-Boy is a proven-performer, owned and enjoyed by thousands of Americans.   Young and old alike have found it the last word   -- simple to use, comfortable, safe and a trouble-free performer.

            Wonder-Boy has, literally, changed the lawn maintenance habits of America.   With it, you can mow lawns to golf-green smoothness without scalping . . . mulch leaves . . .   haul heavy loads . . . roll lawns   . . .     grade . . . plow snow!   Its rear-mounted engine puts heat and fumes behind you . . .   its simple Joy Stick control brings smooth, instant response . . .   and its exclusive Two-Speed Axle provides high and low speeds.

            Try Wonder-Boy yourself.   A few minutes aboard and you'll want this riding power unit on your grounds -- city or country.   For no other unit can do so much for you . . . so quickly and so well.
