Instead of him a deserved scientist in Uzbekistan V.I.Lazunov was assigned as the chief of the department. V.I.Lazunov added great share to substantiate the kinematic parameters of the vertical spindled cotton picking apparatus. After V.I.Lazunov’s death, Professor S.P.Pulatov was assigned as the chief of the department from 1972 to 1983.

In 1971, Professor M.Shoumarova got a scientific degree of candidate of technical sciences first time among Uzbek women. Among teachers of the department, N.P.Polekutin, K.I. Isaev, D.M. Musaev researched about development of plows, M.B.Bogatiryov, G.A. Timofeev, B.U. Utepov about seeding machines, B.M. Koltunov, Sh. Dadajonov, A.N. Shirmanov, M.S.Shoumarova, T.Abdillaev, A. Duskulov about cotton harvesting machines, B.Xudayarov about combined aggregate, A.Sirojiddinov, D.Alijanov about forage grinder. Among teachers of the department, M.S.Shoumarova, T. Abdillaev wrote many books about specialty. They achieved to write and publish 14 books for higher education and special vocational collages.
