Briggs and Stratton 17.5hp Opposed twin

This is a prop replica of a Briggs and Stratton opposed twin. This engine was used in lawn mowers from 1978 to 2002.

On Monday June 10th, 1977 the first pre-production Opposed Twin was built on assembly line 12 and a great product was born. That same year on December 5, 1977, the first customer production build took place, and the customers like M.T.D. anxiously awaited the first multi cylinder engines Briggs & Stratton ever built in its 68-year history

On September 17, 1992 the Plant 5 Focus Factory built the 2,000,000th Opposed Twin, which showed it was still going strong, with great acceptance of the engine by our customers and the final product consumer.

On June 10th, 1997 the Opposed Twin celebrated its 20th anniversary, meaning the engine had lasted the test of time with engine horsepower ranging from 16 1/2 to 21 HP.

On April 24th, 1998 The Opposed Twin Factory along with the rest of what was known as the UED received its ISO Certification. This was a major step in route of not only being a good supplier of engines, but an excellent quality supplier too.

During the year 2000, the Opposed Twin in its 23rd year of production, the product is recognized as a leader in quality at B&S's customers.

May 2000, the engine is eventually going to go out of style because of emissions and the side valve design. It is not going away easy however, because with the end in sight we accomplished another milestone. This month on May 22, 2000, they surpassed the previous Opposed Twin high yearly build total of 324,898 engines. This means there are 4,349,274 of them produced as of that date, and still counting.

Nearly two years later, on May 3, 2002, the Opposed Twin Factory built its last engine and a great engine has now gone away.

Feel free to use this in any mower builds, you don't need to credit me.
