In this type of agricultural reaping device, conventionally, as shown in, for example, Japanese Utility Model Application No. 58-73430, the inner end of one split movable blade and the inner end of the other split movable blade are located in front of each other. By providing a weeding tool with the movable blades positioned so that they are located at This is intended to prevent the planting stem culm from entering between the end unit and the inner end unit located at the innermost part of the units constituting the other split movable blade, resulting in uncut residue. It was getting worse. In other words, when the two split movable blades are closest to each other, the edges on both the left and right sides of each inner end position are inclined edges with respect to the longitudinal direction of the fuselage.
A triangular space is created between the edges of the two inner end units, and even if a stem culm enters this triangular space, it cannot be cut, so the planted stem culm located in front of the triangular space is inserted into the triangular space. The structure is such that it is guided by a weed divider on the side of the triangular space to prevent it from occurring.
