Abstract

PURPOSE:To put a combine into a controlled state immediately after the start of the reaping height control by carrying out the reaping height control based on the detected reaping height at the start of the reaping height control. CONSTITUTION:Reaping heights are detected by an ultrasonic sensor 2 at regular intervals and the detected value is successively renewed and stored. In the case of starting the control of reaping height by an automatic reaping height controlling apparatus, the control is carried out based on the stored data of the detected reaping height.
