用トラクタにおける作業部の昇降制御装置。 A working part connected to the traveling aircraft so as to be able to rise and fall is automatically raised based on the detection operation of a turning detection means that detects the turning of the aircraft, while the working part is automatically lowered when the turning detection means is not activated. In an agricultural tractor equipped with an automatic lift control mechanism, the automatic lift control mechanism includes an automatic lowering operation of the working part based on a non-detection operation of the turning detection means;
1. A lifting control device for a working part of an agricultural tractor, comprising a lowering operation delay means for delaying a non-detection operation of a turning detection means for a predetermined period of time.
