A worm mower for cutting stalk material of any kind is provided, which has a mowing worm, which turns at a high circumferential velocity, and angle of inclination smaller than the angle of friction (glide angle) of the material to be cut, and wherein the circumference of the worm is provided in the axial direction with a continuous cutting surface, which runs parallel to or inclined toward the worm axis, or is stepped with respect thereto.
Claims22
A worm mower for cutting stalk material of various kinds, having an auger cutting worm means, which turns at a high circumferential velocity about an axis of the auger cutting worm means, wherein the auger cutting worm means has an angle of inclination (.alpha.) smaller than an angle of friction (glide angle) of the material to be cut, and wherein a circumference of said auger cutting worm means is provided in an axial direction of the auger cutting worm means axis with a continuous cutting surface, which is slightly inclined (.gamma.) towards said auger cutting worm means axis so that the material to be cut is discharged at right angles to the auger cutting worm axis and is not bent along that axis.
