One side is attached so that its position can be changed, and a swing operation lever is provided to change the position of the vertical conveyance device, and by operating this lever, the receiving position of grain culms supplied to the feed chain can be adjusted and handled. The handling depth of grain culms with respect to the barrel is configured to be freely adjustable, and the operating lever is removably engaged with a screw conveyor rotated by a forward/reverse motor with a substantially constant rotation speed, and the engaged state is adjusted. The present invention relates to a handling depth adjusting device for a combine harvester, which is provided with a control device that operates the motor in forward and reverse directions to automatically maintain the handling depth within a set range based on a result of culm length detection by a sensor.
