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 M�quinas 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.
