Device for mowing crop

摘要

A device for mowing crop comprising a pair of discs adapted to rotate in the cutting plane, driven with equal angular speeds and pairwise in opposite senses and having each outwardly projecting cutters. A cutter may be bent upwardly due to impact on a stone. In order to avoid further damage of the device the circumferential rim of each disc is incised in between every two cutters essentially along an arc of a circle having a center of curvature located outside the circumferential rim.
