Summary:PROBLEM TO BE SOLVED: To provide a desirable crop shear method and a desirable crop shear apparatus device which realize smooth crop shear by suppressing the occurrence of the error about crop length without using special detecting means. SOLUTION: In this crop shear method, the plane shape of a metal plate A is recognized by using a planar shape recognizing means 20 and the crops Aa, Ab of the metal plate A are cut off with a shear means 40. In such a case, the crop lengths La, Lb to be sheared are finally determined (a) after determining the lengths on the basis of the plane shape of the metal plate A which is grasped with the plane shape recognizing means 20 and (b) by making correction to the length, the correction with the deformation of the metal plate A which is separately grasped taken into consideration.
