The company was launched in Milwaukee, Wisconsin in 1908 and today is based in Wauwatosa, Wisconsin. Briggs & Stratton engines are commonly used on lawnmowers, as well as pressure washers, electrical generators, and a wide variety of other applications. Their original cast-iron engines were known for their durability, but the company's success was established following the development of lightweight aluminum engines in 1953. The aluminum engine was the perfect solution for the recently invented rotary lawnmower due to its lighter weight and lower cost. The company has developed a good reputation because of its independent central services distributors (CSDs), low-cost replacement parts and well-designed service literature.
The company started in 1908 as an informal partnership between Stephen Foster Briggs and Harold M. Stratton. S.F. Briggs was born in Watertown, South Dakota, and graduated from South Dakota State College in Brookings (South Dakota) in 1907. The idea for his first product came from an upper-level engineering class project at SDSC. This first product was a six-cylinder, two-cycle engine, which Stephen Foster Briggs developed during his engineering courses at South Dakota State. After his graduation, he was eager to produce his engine and enter the rapidly expanding automobile industry. Bill Juneau, a coach at South Dakota State, knew of Briggs' ambition and the entrepreneurial interests of Harold M. Stratton, a successful grain merchant who had a farm next to Juneau's farm, so he introduced the two. In 1922, their fledgling company set a record in the automotive industry, selling the lowest-priced car ever called the Briggs & Stratton Flyer (also called the "Red Bug") which sold at only US$125–US$150.
Eventually Briggs and Stratton settled on manufacturing automotive components and small gasoline engines. Briggs purchased an engine patent from A.O. Smith Company and began powering early washing machines and reel mowers as well as many other types of equipment. The company went public on the New York Stock Exchange in 1928.
During World War II, Briggs & Stratton produced generators for the war effort. Some pre war engines were made with aluminum, which helped the company develop its expertise in using this material. This development, along with the post-war growth of 1950s suburbs (and lawns), helped secure Briggs & Stratton's successful growth throughout the 1950s and 1960s.
Stephen Briggs went on to purchase Evinrude and Johnson Outboards and start the Outboard Marine Corporation. Frederick P. Stratton, Sr. (the son of Harold Stratton) served as Chairman of Briggs & Stratton until his death in 1962. Frederick P. Stratton, Jr. served as Chairman until his retirement in 2001.
In 1995, Briggs & Stratton sold the automotive component business. The resulting company is Strattec Security Corporation.
In 2000, the company acquired its consumer generator business from the Beacon Group and formed Briggs & Stratton Power Products. The Beacon Group had previously purchased the Consumer Products Division of Generac Corporation (now Generac Power Systems) in 1998. In 2005, the company added Simplicity Manufacturing Inc, and Snapper, Inc, to the Briggs & Stratton Power Products line. Murray, Inc, one of its largest customers, collapsed owing the company $40 million, and to minimize the loss Briggs & Stratton purchased the name, marketing rights and product designs of that company.
On July 29, 2003, Cause Marketing Forum presented Briggs & Stratton Corporation and National Wildlife Federation (NWF) with a Halo Award in the Best Environmental/Wildlife Campaign category, for their efforts in generating awareness of the environmental benefits of mower tune-ups.
Acquisitions, agreements and joint ventures
- Farymann Diesel GmbH (1979–1984) – Based in Lampertheim (near Mannheim) in Germany, this was the first foreign acquisition Briggs & Stratton had ever made and was a poor fit with the company's acknowledged expertise in high volume, low cost production. They officially completed the acquisition on May 29, 1979. Despite investing in new production methods, Briggs & Stratton never understood the very low volume, highly customized nature of the air-cooled diesel engine market. After considering adding Italy's Lombardini to increase its presence in the diesel market, as well as a failed attempt to develop its own designs, Briggs & Stratton accepted defeat and sold the company to a private investor for a minimal amount to avoid further liabilities. Since the energy crisis had not affected the US market's preference for gasoline engines, enthusiasm waned rapidly at management level for diesel engines.
- Daihatsu Briggs & Stratton (DBS) – In an effort to stave off Japanese competition during the 1980s, Briggs & Stratton entered a 50/50 joint venture with the Daihatsu Motor Company in Japan. Located in Shiga Prefecture (50 miles (80 km) from Osaka, Japan), construction on the then-57,000-square-foot (5,300 m2) plant began in December 1986 and was completed in April 1987. This joint venture was notable for the manufacture of vertical and horizontal crankshaft engines from 12.5 to 22 hp (16 kW) under the Vanguard brand. Today the plant employs roughly 100 people on two shifts and manufactures Vanguard V-twin engines ranging from 14 to 36 hp (27 kW).
- The Mitsubishi Agreement – The Vanguard line initially consisted of three single-cylinder engines and several V-twin engines. The V-twins, made by DBS, had sold very well but the single-cylinder engine models, originally produced at Briggs & Stratton's Menomonee Falls, Wisconsin plant, didn't fare so well. Briggs & Stratton needed to solve this problem, so, following discussions with several Japanese engine manufacturers, it entered into an agreement with Mitsubishi Heavy Industries Ltd. of Tokyo, Japan. Briggs & Stratton produced only certain parts for the engines, while Mitsubishi was responsible for overall production and shipping. The completed single-cylinder Vanguard engines were shipped directly to customers worldwide. Briggs & Stratton had exclusive marketing rights only in North America, Europe and Australia/New Zealand. MHI had exclusive marketing rights (under their own brand name) in Malaysia, Taiwan, South Korea and Japan. In other countries both companies competed with the same product under their own brand names which led to considerable friction, and together with escalating production costs in Japan, caused this otherwise successful relationship to fail. Briggs & Stratton commenced marketing alternative U.S.-made single-cylinder engines under the Vanguard brand in early 2007.
- The Komatsu Zenoah Venture – In May 1987, Briggs & Stratton entered into an agreement with yet another Japanese company, executing a 10-year contract with the Komatsu Zenoah Company of Tachikawa, Japan. Under the terms of the contract, Komatsu would manufacture a 2-cycle, 4 hp (3 kW) engine, in which Briggs & Stratton would purchase and distribute in the United States, Europe, Australia and New Zealand. Said Fred Stratton, "This venture was not successful, because the rising price of the yen made the engine too expensive in the U.S."
- The Toro Agreement – In 1999, Briggs & Stratton made a license agreement with The Toro Company of Bloomington, Minnesota USA. to produce the Toro R*Tek piston ported version of their E series 2-stroke engine (AKA Lawn-Boy DuraForce) for use in Toro Snow Throwers. The R*TEK engine was a 141cc 2 cycle that produced from 4 hp to 6.5 hp with only the need to adjust the RPMs ranging from 3700 rpms to 4000 rpms and ran using a gas & oil mix of 50:1. A High Out put 7-HP model was made (Engine Model# 84330) for the use in heavier duty snow throwers such as the single stage Snow Commander (2001-2008) & 2 stage Power Max 726TE/6000 (2004-2008), the extra .5 horse power was obtained using Transfer Ports in the piston & cylinder wall and ran at the same operating speed as the 6.5 hp engines (4000rpms). Production stopped in 2011.
- The aluminum engine – This was introduced in 1953 as a means of having a lighter-weight engine for applications such as rotary lawn mowers. It was improved five years later in 1958 with the introduction of the Kool-Bore (all aluminum) and Sleeve-Bore (aluminum, with a cast iron cylinder liner).
- Easy-Spin Starting – This compression release, implemented as an extra hump on the intake lobe of the camshaft, was introduced in 1961 to reduce the effort required to start an engine. In 1982, a new U.S. federal safety regulation required lawnmower blades to stop spinning within three seconds of the operator letting go of the handle. The least costly, most common way of complying with the new regulation was to put a flywheel brake on the mower engine, to stop the engine (and therefore the blade) immediately when the handle was released. Briggs & Stratton engineers found engines with the Easy-Spin camshaft were unacceptably difficult to restart after being braked to a quick stop. The Easy-Spin lobe hump was moved to the exhaust valve, but this reduced engine performance. The intake-side Easy-Spin remained in use on Briggs & Stratton's engines larger than those used on mowers subject to the brake requirement, but was discontinued in 1997 due to tightening emission regulations.
- The Synchro-Balanced Engine – This 1966 innovation was designed to attenuate vibration caused by the reciprocating mass of a single-cylinder engine. The design was a series of counterweights opposing the crankpin.
- The Twin Cylinder Engine – This engine was introduced in 1977 as a means of competing with Briggs & Stratton's rivals, particularly Japanese firms like Honda who were cutting into traditional Briggs & Stratton markets by producing lawn mower engines (and later, complete lawn mowers). These first models were rated 16 hp (11.9 kW) and displaced 40 cubic inches (656 cc), but were joined in 1979 by 42 cubic inch (694 cc) models rated at 18 hp (13.4 kW). The original price for the 16 hp (12 kW) version was $70 lower (at US$228) than their single-cylinder cast-iron version bearing the same power rating.
- Industrial/Commercial (I/C) – This series of engines, initially ranging from 3 to 18 hp (13 kW), was introduced in 1979 as Briggs & Stratton's answer to high quality commercial-duty engines produced by competitors. These engines include heavy-duty features such as Stellite exhaust valves, upgraded bearings, cast iron sleeved cylinder bores and high-capacity air cleaners.
- Briggs & Stratton HYBRID – In 1980, at the tail end of the energy crisis, Briggs & Stratton developed the first gasoline-electric hybrid automobile. "The Hybrid" was designed by Brooks Stevens and powered by a twin-cylinder 16 hp (11.9 kW) Briggs & Stratton engine and a large electric battery.
- Magnetron Ignition – This solid state ignition system introduced by Briggs & Stratton in 1982 eliminated the points and condenser system, the performance of which steadily degraded between required periodic maintenance service. Magnetron was made available for retrofitment to Briggs & Stratton engines made since 1963. Competitor Tecumseh had made a capacitor discharge ignition setup since 1968 for their cast iron engine models, expanding its availability and making it standard equipment on vertical shaft engines powering lawn mowers in late 1976, five years before the advent of the Briggs Magnetron. Defunct competitor Clinton Engines commercialized a piezo "Spark Pump" ignition without breaker points in the early 1960s.
The Briggs & Stratton logo was always a masthead, but it has been changed several times over the course of the company's 80-plus years.
- Pre War logos (1931–1943) – This logo started off with a diamond shape and read Briggs & Stratton and its home city of MILWAUKEE, WIS., U.S.A. below it; in the middle, it had the words 4 CYCLE on the top mast and the words GASOLINE MOTOR and phrase MADE IN U.S.A. on the bottom mast. About 1934 Briggs & Stratton added the more familiar shape of a diamond split across the center with a banner.
- Gold Logo (1948–1963) – This logo had the name BRIGGS STRATTON and its home city of MILWAUKEE, WIS., U.S.A. below it; in the middle, it had the words 4 CYCLE on the top mast and the words GASOLINE ENGINE and phrase MADE IN U.S.A. on the bottom mast.
- Gold Logo (II) (1963–1976) – Although similar to the last logo, this had differently arranged wording: The name BRIGGS STRATTON was written in a new logotype, however, this design also included the horsepower rating above the gold logo in the white field, its city of location were in the middle as before, only this time the patent numbers were eliminated (if you look at a decal on a production engine) from the bottom portion of the mast. There were some engines produced until 1977 that used the prior logo from 1948.
- The Red, White and Black Logo (1976–present) – This is the company's current logo. The logo has the name BRIGGS STRATTON in black letters on the white midsection of the masthead. The words 4 CYCLE ENGINE are on the red top portion of the mast and the city line MILWAUKEE, WISCONSIN, U.S.A. is written on the black bottom portion of the mast. Although the logo hadn't been changed much since then, the wording on the top and bottom sections of the mast were removed in 1985, although the company continued to use these two sections with the respective wordings ORIGINAL (red section) and SERVICE PARTS (black section) until 1989.
