機の作業部自動上昇装置における解除構造。 A linkage mechanism is provided between a steering operating tool such as a handbrake pedal and a lifting hydraulic lever of the working part so that the lifting hydraulic lever is automatically displaced to a raised position by operation of the steering operating tool and the working part is raised. In an automatic lifting device for a working part of a mobile agricultural machine connected via a
In the linkage mechanism, there is provided a non-contact mechanism that allows the lifting hydraulic lever to freely connect with the steering operating tool from the working position that controls the transformation operation to the raised position of the lifting hydraulic lever linked to the operation of the steering operating tool. An operating link that can change its shape to a working position is provided, and the operating link includes:
A link release mechanism is provided that can lock and hold the non-working position and release the link between the steering operating tool and the lifting hydraulic lever in a state where automatic return to the working position is permitted by the biasing force of the return projectile. A release structure for an automatic lifting device for a working part of a mobile agricultural machine, characterized by:
