This work was carried out at the location of Potrerillo (Caldono) and at the Indian Reservation Maria (Piendamo) in the Northern zone of Cauca department (Colombia). Two different implements using animal draught (Arandino plow and conventional plow) and a manual tool - the hoe- were compared; A preliminary trial was made at the first location in order to adjust the methodology which allowed to clear some elements to plan the definitive trial at La Maria. It contributed to the methods for research on animal draught in slopes. Compared with the conventional plow and the hoe the Arandino plow provided the highest width of cut, depth of labor and field capacity, and the least cost per hectare. For the farmers and plowmen it was more profitable to carry out the plowing labor with the Arandino plow because it provides a larger tilled area in a shorter time, better quality of materials and because it is lighter and easier to handle. The conventional plow showed larger field efficiency than the Arandino. The manual tillage (using the hoe) will be useful if the own fanner or the community carry out the labor.
