For conditions of nuzzle in the green house it is necessary to define the specific cutting resistance and coefficient of moving resistance so that the motor power selection is easier. Analyses of power distribution based on electrical measuring showes that the usage of electromotor is 70%, specific cutting resistance has the value of about 5-7 N/square cm and the coefficient of roling resistance 0.63. At 60 rpm regime there is enough power reserve to increase the digging depth or the working width from 30 to 60 cm, with 25 cm of digging depth. Theoretically at 80 rpm regime it is possible to digg at 17 cm depth, with 4 roses.
