FIELD: agriculture, in particular, power-consuming soil tillage equipment. SUBSTANCE: method involves adjusting pressure applied to propellers in direct proportion to working tool draft. Controlling is conducted by means of pressure in pressure line of hydraulic pump 4 of one of members of planetary mechanism 2 of drive 5. Apparatus for controlling agricultural unit with tractor has hydraulic system 12 connected with drive 5 for moving working tool 7 in horizontal and vertical directions. Apparatus has planetary mechanism 2 whose one member is connected through hydraulic pump 3 and hydraulic distributor 4 with drive 5 for moving working tool 7 to provide for pressure applying control. EFFECT: increased efficiency, reduced power consumption and enhanced reliability in operation. 3 cl, 3 dwg
