TRACK SCARIFIER OF A TRACTOR Russian patent published in 2021 - IPC A01B37/00 A01B49/02 G05B1/00 

FIELD: agriculture.

SUBSTANCE: track scarifier of a tractor comprises side sections secured on a transverse beam, wherein each section comprises rippers (6) arranged in two rows parallel to the transverse beam in a staggered order relative to each other, and blades (5) made in the form of ripper stands. Installed behind the blades (5) is a reactive battery of toothed disks (4), wherein a drive battery of toothed disks (3) is installed behind said battery. The forward-directed teeth of the disks of the reactive battery (4) are located above the lugs of the rippers (5) of the rear row opposite the midpoints of the intervals between the adjacent blades of the front and back rows. The teeth of the disks of the drive battery (3) are located between the teeth of the disks of the reactive battery (4). Installed on the working body of the track scarifier – blade (6) – from the back side at an angle α = 8...9 degrees from the vertical axis of the blade and a height h = 5 cm from the surface of the tilled soil is a sensor (9) for non-contact measurement of the moisture content of the soil, connected to the moisture measurement unit, connected, in turn, with the control unit. The batteries of active toothed disks (3) are driven from the power take-off shaft of the tractor by means of a cardan joint, a reducer gearbox, a variator, a shaft, and a chain drive. The variator and the rotation speed sensor of the active toothed disks (3) are connected to the control unit.

EFFECT: formation of erosively dangerous particles during tillage along the tractor tracks is reduced.
