Results and discussion corresponds to three cuts between every two plants in the row can be calculated using the following equitation: V max 100 d = (5.23) T min where d is the average intra-row distance between plants and Tmin the time in which one full rotation of the system can be achieved with rated rotational speed. u = 60 rpm = 1 rps → T = 1 s (5.24) rated min In Table 5.6 maximum forward speeds of the carrier for several intra-row distances are given. Table 5.6 Maximum forward speeds of the carrier for several intrarow distances d [mm] 50 100 200 300 400 500 Vmax [m/s] 0,05 0,1 0,2 0,3 0,4 0,5 Vmax [km/h] 0,18 0,36 0,72 1,08 1,44 1,8
