This paper presents a procedure for the calculus and dimensional optimization of a seeds hopper volume from a universal seeds drill. First, the meaning and importance of some constructive parameters taken into account in the procedure are fully explained and exemplified. Then, the mathematical algorithm underlying the hopper's cross-sectional area maximization is developed. The procedure is applied on a hopper from a real seeds drill. It is important to note that the hopper's volume has been already maximized by the designer. Therefore it will be tested whether the proposed procedure is capable to add value to the method used by the designer. Under these conditions, it is found that the proposed method has further succeeded an increase in cross-sectional area from 0,89 m2 to 0,93 m3. Considering that the total length of the hopper in this example is 3,086 m, an overall increase in volume of 12,3 L is obtained.
