Abstract: The time required to harvest plant crops is important to the plant properties. It is affected by design of the harvest equipment and the desire for high-quality products with low energy usage. In this study, we determined the cutting properties of lavandin (Lavandula x intermedia Emeric ex Loisel.) at different harvesting time to be applied to the design of mechanization applications. Cutting properties of lavandin (an important medicinal aromatic plant) harvested on 12, 17, 22 and 30 July, 2012 (H1, H2, H3 and H4, respectively) were measured at the bottom and top sections of the stalk. Measurements included maximum force, bioyield force, shearing force, bending stress, shearing stress, shearing energy, and shearing deformation. The highest maximum force (18.45 N) was at H4 on the bottom section, and the lowest was at H1 on the top. Maximum values for bioyield force, shearing force, and bending stress were at H4 on the bottom section, and corresponding minimum values were at H1 on the top section. Shearing stress decreased at successive harvest dates for both stalk sections. Strength measurements for bottom sections of the stalk were greater than those for top sections. When reduced harvesting force is needed because of harvester design or harvest procedures, harvesting near the top of the stalk is recommended
