A study has been conducted in order to evaluate the best mechanical solution for the harvesting of cardoon (Cynara cardunculus L. ) seed. Employing a self-propelled forage harvester (New Holland CS540), a comparison (in terms of performance and quality of the work) was carried out between a dedicated cardoon head designed by CRA-ING for the harvest of separate fractions and a wheat head, used with two settings, traditional and modified. The harvest trials were realized on a cardoon cultivation sowed on a marginal land. The best results were achieved using the modified head for wheat while the outcome of the CRA-ING head was penalized by the working width, lower than the wheat head. Concerning the quality of work, the traditional wheat head showed the highest values of capitula losses. Introducing some modifications, such losses were reduced of 59,2%, but in this case the CRA-ING head showed the lowest losses, saving till 86% of the inflorescences. The test has evidenced that, compared to the commercial ones, the CRA-ING head, performing simultaneously the cutting and windrowing of the plants, may facilitates the harvesting and baling of the lignocellulosic fraction left on the ground. In the common yards, the traditional heads would require, indeed, the passage of further implements (mower and rotary rake), with an increase of the total costs.
