FIELD: agriculture.
SUBSTANCE: grouser agricultural tillage knife contains a disk having a central hole and made with the possibility of being attached to the tool with the possibility of rotation around the axis of rotation. The disk has an outer circumference and a plurality of stepped flat recesses in the disk from a position essentially at the outer circumference to a central hole. Grouser agricultural tillage knife device contains a disk having a central hole and made with the possibility of attachment to the tool with the possibility of rotation around the axis of rotation. The disk has an outer circumference, a plurality of stepped flat recesses in the disk from a position essentially at the outer circumference to a central hole, and a sleeve attached to the disc around the central hole. Grouser agricultural tillage knife device contains at least two disks. Each disk has a central hole and is rotatable to the tool about a substantially horizontal axis of rotation. Each disk has an outer circumference and a plurality of stepped flat recesses in each disk from a position substantially at the outer circumference to a central hole. On the shaft between at least two disks there is a spacer coil protruding in the radial direction outward from the central hole. Each of the plurality of stepped flat recesses has a depth and a width. The depth is 50% or less of the width.
EFFECT: uniform cut of the soil and a reduction in soil scattering are ensured.
