FIELD: agriculture.
SUBSTANCE: device is constituted of two symmetric, and located in inversed manner relative to the longitudinal axis of the machine sections of the working body. Each working body of the section is made in the form of a disk with gimbal-mounted blades on it. The front edge of the blade is beveled toward the direction of rotation of the disk. The middle part of a blade is connected tangentially to the outer surface of the disc with a spring, occasionally elongated when beveled surface of the blade with a pin fixed on the machine case. The pin is mounted so that it can move along an arc of 0° … 90° of a circle with a radius greater than the radius of the disk by the departure of blades over its surface.
EFFECT: constructive implementation will ensure the destruction of the chunks of land moving up with elevator into smaller fractions.
