History of the Small Engine: Lawn Mower Edition!

From tanks to tractors, small engines have a storied history. Here at the Small Engine Blog we look at the transformation of the small engine and the various and sundry things that it powered today!

Lawn Mowers: The Beginning

The first formal lawns were thought to be of France in the 1700s, tended to by grazing animals or hand-cut with shears and scythes. In 1830, Englishman Edwin Bear Budding was granted the patent for the first mechanical lawn mower, based on a tool used to uniformly cut carpet and comprised of a series of blades around a cylinder.

Nearly 40 years later, the reel lawn mower came to the United States. Initially made to be horse-drawn, Elwood McGuire of Richmond, IN designed the first widely popular human-powered push lawn mower.

From Horses and Humans to Fuel

In 1902, Ransomes of Ipswich, another English company, produced the first commercial buyable lawn mower powered by an internal combustion gas engine. 1919 brought the first gas powered lawn mowers, manufactured by Colonel Edwin George, and gang mowers, those with multiple sets of blades, to the United States.

Throughout the early 1900’s, steam-powered tractors, many produced by Caterpillar, worked on major projects from the clean-up after major natural disasters to the construction of big infrastructure like the Los Angeles Aqueduct. 

Engine Advancements

In 1953,  Briggs & Stratton revolutionized the lawn and garden industry by developing the first lightweight aluminum engine. This light aluminum engine improved the ease of use of rotary lawn mowers and was further advanced in 1958 with the introduction of Kool-Bore (all aluminum) and Sleeve-Bore engines. Further advancements have been made by Lombardini, a part of the Kohler Group, offering a 20 hp water-cooled gasoline engine.
