FIELD: agriculture.
SUBSTANCE: invention relates to agricultural equipment. Disclosed is agricultural machine (1) for soil treatment or for seeds sowing with towed chassis (2) and with working tools (3), distributed on longitudinal bar (4) from several sections. At that, said longitudinal bar (4) includes, at least, two primary beams (4a, 4b), in working configuration passing essentially across movement direction (A). At that, with each primary beam (4a, 4b) secondary beam (10a, 10b) is connected by means of two crank rod devices (11). Said working tools (3) are installed on these secondary beams (10a, 10b). At that, each secondary beam (10a, 10b) rests against soil by means of two support wheels (12) and made with possibility of free movement during operation to follow field profile. Secondary beams (10a, 10b) crank rod devices (11) position is independent, wherein each crank rod device (11) is tilting during operation.
EFFECT: invention enables to increase working tools position accuracy relative to soil to follow field profile.
