The Drott Manufacturing Company was a manufacturer of heavy equipment buckets. The company existed from 1916 until 1968.
The company founded (as the Drott Tractor Company) by Edward Drott in 1916.[1] The company was based in Butternut, Wisconsin before moving to Wausau, Wisconsin. In 1923, after several re-organizations, it became the Drott Manufacturing Company. Drott was taken over by Tenneco in 1968 and became a division of Case Corporation which was owned by Tenneco.
Drott developed buckets for other manufacturer's construction bulldozers, including one of the first of its type for Caterpillar in 1930.[2] The bucket held roughly 1 cubic yard of soil. The company's best-known product was the Drott 4 in 1 bucket.[3] This was a tractor attachment with four functions: dozer, clamshell, bucket and scraper. The "International Drott" was an International Harvester tractor fitted with Drott equipment.[4] In 1950, International signed an agreement with Drott to produce the machines under the name "International-Drott."
The Drott 4 in 1 bucket was manufactured in the UK by Rubery Owen[5] and tractors fitted with this equipment became known as "Drotts".
