FIELD: agriculture.
SUBSTANCE: device comprises rotor with rakes and spring fingers and drive installed on frame with support-adjustment wheels. Axis of rotor is arranged in vertical plane and is inclined forward along with travelling direction. Spring fingers are arranged at the ends of rakes. Each rake is arranged as hingedly joined to rotor and with possibility of displacement within the borders constrained with supports, perpendicular to plane of rotation. Each rake is equipped with inertial controller of force of pressure at spring fingers. Inertial controller of pressure force comprises weight fixed hingedly on bracket of rotor and interacting with rake by means of kinematic joint. Weight fixation is arranged as controllable.
EFFECT: invention will make it possible to improve efficiency of stools opening.
