This method eliminates the mechanical force in clash with fertilizer and suggests replacement of it by wind force. Wind power produced by two circular fans produce powerful wind and their openings is leaning toward sides of tractor. The required force to turn the fans and the mixer inside fertilizer tank is provided by tractor PTO shaft. Fertilizer is lead into leading pipes by an adjustable valve that is under tank and circular fans drawn fertilizer by suction inside themselves and project out them with a directed force. As a result, fertilizer to be thrown farther. Using this method, the higher width dispersions achieved. power take off shaft to provide required force to turn fans with higher rotation, increases its 540rpm turn by a bigger pulley with a conversion factory of 1 to 4 to about 2200 rpm. to evaluate the system, field tests completed on optimal advancing velocity, width dispersion, and uniformity of dispersion. optimal advancing velocityof this system set up 10km/h and its width dispersion, 46meter and its uniformity of dispersion, by average, measured 5 grams per meter square.
