<p>PROBLEM TO BE SOLVED: To solve such the problem that, since a conventional second cutting blade has a configuration that both right and left sides of a cutting blade frame is supported by a pair of right and left support frames, the second cutting blade inclines when one of the longitudinal support frames comes into contact with an obstacle or the like.SOLUTION: In a combine, a support mechanism 21 of a second cutting blade 20 is configured so that a lateral cutting blade 23 attached with the second cutting blade 20 is attached to lower parts of a plurality of longitudinal support frames 22 directed in a longitudinal direction. One of the longitudinal support frames 22 is attached to the cutting blade 23 while the length thereof is fixed, and the rest of the longitudinal support frames 22 are attached to the cutting blade 23 so that the length thereof is variable.</p> |
