The work deal with economic classification of two variants of technological process by carrot production. First variants presents raising of carrot on ridge, the second raising of carrot on uphill beds. Datas needed for model calculation were detected by direct metering in real conditions, with investgation by users and producers of machines. With utilization of these statement were with the help of programme AGROTEKIS provided model calculation of operating costs of machines and mechanical tools. These data were exploited for calculation of costs by carrot production in both assessed variants. The results shows about mild growth of costs by growing of carrot on ridge (difference circa 3,5 %). Calculated values by general costs with overhead costs are 80 120–99 772 CZK.ha−1. The biggest costs part falls on soil preparation (25–30 %), harvest and manipulation (43–46 %).
