FIELD: agricultural engineering. SUBSTANCE: device comprises double transmission 8. The latter consists of two superposed angular transmissions 15 and 16 which can turn relative to each other through support 21 around vertical axis A-A. Double transmission has holding shackle 9 and support 31 resting on it via springs. Said support has a journal for connection with crosspiece 7 with a provision for turning around longitudinal axis C-C.
