FIELD: agriculture, equipment. ^ SUBSTANCE: invention concerns agricultural engineering. It includes a hitch tongue, a central middle and edge sections with tools attached to them, and a section lifting device in the form of balance wheels with hydraulic actuator. A device of bringing middle and edge section into transportation mode is adjusted by a hydraulic cylinder and comprises an antiparallel link with compensation sections at the ends of cross drafts. Pin of the hydraulic cylinder is connected to one of the cross draft end axes at a swivel on the front end of C-shaped beam. The hitch tongue is connected to the central section and includes an immobile part comprising parallel hollow beams, and a mobile part comprising bars pulling out of the hollow beams. The mobile part is fixed inside immobile part by retainers. Each transportation pivot beam is attached to the main beam of each section by brackets. ^ EFFECT: improved operation reliability of a tillage device during transportation. ^ 4 dwg |
