Maquinas Agricolas Jacto S.A. was founded in 1951 by a Japanese immigrant, Shunji Nishimura. In 1948 he patented the first manual knapsack duster. The company currently leads the Jacto group, which started in the 30's in a small mechanical workshop. The workshop was transformed into a factory, giving birth to the Máquinas Agricolas Jacto Ltda. The name was inspired from the smoke trail left in the air from the most modern creation by aeronautical engineering at the time: the jet plane.
