<P>PROBLEM TO BE SOLVED: To prevent a reaping height detector from breaking even if external force is applied to a grounding body from longitudinal and lateral directions by the movement in the longitudinal and lateral directions of a reaping part. <P>SOLUTION: This reaping device (27) includes: a support shaft (1) in the vertical direction; a first support body (2) supported to the support shaft (1) in such a way as slidable in the vertical direction and rotatable in the lateral direction; a longitudinal shaft (3) in the longitudinal direction in the rear of the first support body (2); a second support body (4) whose top is supported to the longitudinal shaft (3) in such a way as rotatable in the vertical direction; a sensor shaft (5) in the lateral direction disposed below the second support body (4); the grounding body (6) extending downward to the rear from the sensor shaft (5); and an angle sensor (10) for detecting the angle of rotation in the vertical direction of the grounding body (6). <P>COPYRIGHT: (C)2012,JPO&INPIT |
