Methods for efficiency evaluation of MX-1.8 GV cotton pickers in horizontal-spindle design

The article is devoted to determining the economic profitability of MX-1.8 GV cotton pickers in comparison with handpicking. The article presents the results of field tests of a horizontal-spindle design of MX-1.8 GV cotton harvester performance, compared with the results of numerical studies obtained using a computer program. The results obtained were used to further determine the economic efficiency of machine harvesting. The costs of machine and handpicking are determined. On the basis of numerical studies, it was proved that machine harvesting using MX-1.8 GV cotton picker is economically profitable at an open crop yield of more than 2.75 t/ha.
