They have not gained the expected popularity among a large majority of farmers because until recently they tried as alternative to traditional single-pourpose machinery system which did not present sufficient time saving advantage to justify heavy investments. The recent experiences at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), India and the Centre of Agricultural Research for the Semi-Arid Tropics, Petrolina,PE, Brazil (CPATSA) in the adoption of this type machinery system as an integrated component of improved farming systems has shown the possibility of increasing crop production and better time saving advantage even for small land holdings. amechanization aMecanização Agrícola aSistema de Produção aTração Animal aAnimal-drawn aFarming system aPower machinery tAgricultural Mechanization in Asia, Africa and Latin Americagv. 16, n. 1, p. 38-44, 1985.
