Müller tractors were 4WD articulated tractors built in Brazil. The company was founded in 1956 by a German immigrant, Mr. Müller. They continued to build tractors until 2002, when the company was sold to Proton Primus of Brazil. They also manufacture CompactorRollers.
Tractors were exported to the USA by Müller America in Houston, TX and CBT/USA in Colorado Springs, CO, which was the importer of CBT tractors from Brazil.
Müller signed an agreement with Tractores BM of Uruguay to supply tractors, and later licensed their design to Tractores BM.
