FIELD: agriculture.
SUBSTANCE: hand scythe comprises a blade, a cutting contour and a handle. The cutting contour is arranged along a cycloid, the length of which is equal to the length of the cutting contour of the scythe. On the cutting contour of the scythe there are additional cuts formed by sections of crossing several additional cycloids, crossing points of which form a serrated profile. The serrated profile surrounds the cutting cycloidal contour of the scythe in points O, N, A, B, C, D. Tangents to additional cycloids in points of their crossing have angles that are smaller than angles of grass friction against the surface of the cutting contour of the scythe.
EFFECT: reduced power inputs, higher efficiency of cutting.
