They were the best
How Greed KILLED America's Lawnmower Empire
That sound is a 1965 Lawn Boy D-400 starting on the first pull, 60 years after it rolled off the Galesburg, Illinois assembly line.
For four decades, the lime green deck was the default mower of the American suburb, built so tough that owners willed them to their sons.
Today, you can buy a Lawn Boy at any big box store, but it shares almost nothing with the iron-lunged machine that built the brand.
However, this company was not killed by Honda, by the EPA, or by changing tastes.
It was killed by the people who owned it.
The year is 1934.
America is five years into the Great Depression.
Lawn mowers for most homeowners are still hand-pushed reel mowers, the same design Edwin Budding patented in England in 1830.
A powered mower is a luxury item, and luxury items are not selling.
In Milwaukee, Wisconsin, the Evinrude Manufacturing Company has a problem.
Its business is small two-stroke engines for outboard boat motors, and during the Depression, almost nobody is buying a new boat.
The factory has workers, the warehouse has parts, but the order book is empty.
Therefore, the company does what desperate manufacturers have always done.
It looks at its inventory and asks what else those engines could push.
The answer is a steel deck, four small wheels, and a vertical shaft adaptation of an outboard powerhead.
The engine, designed to push a fishing skiff across a Wisconsin lake, is rebuilt to spin a horizontal blade across a suburban yard.
In a literal sense, the first Lawn Boy is a boat motor that learned to walk.
But the real innovation is not the engineering.
It is the name.
In 1934, Evinrude trademarks Lawn Boy, not a brand of mower, a brand of helper.
The marketing positions the machine as the family's mechanical son, the one who never complains about Saturday chores.
The lime green paint, the cult following, the 30-year reign over the American suburb are all still decades away.
What matters in 1934 is that the engine starts on the first pull and runs on a fuel mix any homeowner can measure with a soup can.
The two-stroke rasp that would define 40 years of American summers cuts through the air for the first time and nobody who hears it forgets it.
However, before Lawn Boy can become an empire, it has to survive a war.
By 1952, the suburb the engine was waiting for finally exists.
The GI Bill, three-bedroom ranch houses, and roughly 13 million new homes built between 1946 and 1958 have created something America has never had before.
A continent of lawns that nobody wants to cut by hand.
Evinrude, now operating its mower division out of Galesburg, Illinois, is ready.
That year, Lawn Boy releases the D-series engine and the design choices made in that small Illinois plant set the standard for the next 30 years.
The cylinder is aluminum with a cast-iron sleeve pressed inside, a configuration borrowed from aviation engines.
It is the kind of engineering a wartime piston engine machinist would recognize on site and in 1952, a lot of the men working the Galesburg line are exactly that.
The deck is magnesium, less than a quarter the weight of steel and immune to rust, a metal almost no other mower manufacturer is willing to pay for.
The whole machine weighs around 46 lb.
A 9-year-old can push it.
A grandfather can lift it into the back of a station wagon without help.
Therefore, when the lime green paint goes on the deck in 1954, the brand has its silhouette.
From two houses away on any block in Cleveland or Phoenix or Levittown, you know what is cutting that grass before you see the operator.
But the engineering choice that mattered most was the one Lawn Boy made about combustion.
