Companhia Brasileira de Tratores (CBT) was a Brazilian manufacturer of tractors from 1959 until closing in 1995. CBT began operations by importing and assembling Oliver tractors. Local production and design of components increased and by the 1970s CBT was selling tractors under their own brand, although with a strong Oliver lineage. New designs continued into the 1990s, and CBT tractors were exported throughout the Americas. CBT ceased production in 1995 when market reforms in Brazil eliminated protections for domestic manufacturers.
