摘要

PROBLEM TO BE SOLVED: To improve operation accuracy in farming field surface in a controller of an agricultural working vehicle for automatically carrying out field planting operation such as rice transplantation together with traveling of a machine body. SOLUTION: In the controller of the agricultural working vehicle, an operating device liftable to a traveling machine body enabling turning and traveling is provided and an automatic turning controller for carrying out each motion of raising or lowering of the operating device to non-operating position and lowering of the operating device by prescribed timing in turning and traveling process is provided in the traveling machine body. A float is provided in the operating device. A field surface is constituted so as to enable leveling of the ground and the operating device is constituted so as to enable lifting and lowering control so that the operating device becomes prescribed height to the ground when the float is traveled in grounding state. When control sensitivity of the lifting and lowering controller is set to insensible side from a prescribed value, practice of the automatic turning controller is stopped. COPYRIGHT: (C)2007,JPO&INPIT
