The aim of this study was to manufacture and evaluated the performance of the prototype of cultivating device during cultivating sugar beet crop.         The studied variable included: the kinematic index (λ) of 9.43, 14.14, 18.86 and 28.28, the number of cultivator blades of 8, 12, 16 and 24 and the cutting angle of cultivator blades 90°, 110° and 130°  on weed control efficiency, injured sugar beet plant percentage, wheel cultivator slip, fuel consumption and energy requirements. -    The blade cutting angle of 90° gave the highest values of weed control efficiency and injured sugar beet plant percentage. -    The kinematic index (λ) of 18.86 and the number of cultivator blade 16 gave the best results of the weed control efficiency, injured plant percentage, and fuel consumption. The kinematic index (λ) range of 9.43 and 14.14 gave the lowest value of the specific energy requirements
