Claims

[Scope of utility model registration request]

A reaping section 4 is provided on the traveling vehicle body so that it can be raised and lowered by a hydraulic actuator 8, and the reaping section 4 is provided with a ground sensor 13 for detecting its height above the ground, and a spool 15 of a control valve V for the hydraulic actuator 8 is provided.
, 16 and the sensor 13 are interlocked and connected via a mechanical linkage mechanism to constitute a cutting height control mechanism 23 that automatically maintains the height of the cutting section 4 above the ground within a set range. A manual operating tool 35 is connected to the mechanical linkage mechanism via a flexibility mechanism 41, 42 that allows the cutting height control mechanism 23 to raise and lower the control valve (2). The control valve □ can be operated up or down by operating the accommodating mechanisms 41 and 42 beyond the accommodating range, and the manual operating tool 35 is biased to return to and maintain the neutral operating position. The cutting height control mechanism for a combine harvester is provided with a mechanism 44, in which a holding member 54 for fixing and maintaining the manual operation tool 35 at the raising operation position is attached to the reaping section 4.
A cutting height control mechanism for a combiner, characterized in that it is provided in a state in which delimitation is released by a pressing force from the sensor 13 when the height rises above a set value.
