Chelyabinsk Tractor Plant (Russian: Челябинский тракторный завод, romanized: Chelyabinskiy traktornyy zavod, abbreviated ЧТЗ, ChTZ) also known as CTZ-Uraltrak (ЧТЗ-УРАЛТРАК)[5] is a tractor construction plant in the Russian city of Chelyabinsk.

[6] The plant was founded in 1933; the first product was a 60 hp tracked tractor C-60 (Сталинец-60, Stalinets-60) fueled by petroleum ether (Benzine).

[1] During World War II seven other industrial entities (including most of Leningrad's Kirov Plant and 15,000 of its workers[7]) were either wholly or partially relocated to Chelyabinsk, the resulting enterprise commonly known as "Танкоград" ('Tankograd', or 'Tank City').

[11][12] However the factory claims to have fulfilled an order for an unspecified number of diesel engines in December 2022.

[13] In 2023, the factory itself was sanctioned by the United States and Ukraine due to its supply of engines to Russian troops for military equipment.
