FIELD: agricultural engineering, in particular, equipment hitched to pulling vehicle such as tractor. SUBSTANCE: apparatus has left and right double-link rotating kinematic pairs mounted on frame and formed by pivotally connected tines and bars. Each bar is connected with power cylinder 14 of rotational drive and is connected through hoses with sectors. Kinematic pairs are formed as flat pivotal mechanisms positioned in single vertical plane. Left bar 3 and right bar 5 are connected with hydraulic cylinder 14 through paired multiple pulley block with two runs of ropes 15,16, which run crosswise about common double unit mounted on movable stem of cylinder 14. One end of each rope run is rigidly fixed and other end is connected with related bar through block 18. EFFECT: simplified and compact construction, lowered center of gravity and enhanced reliability in operation. 7 dwg
