する 移動農機の制動装置。[Scope of Claim for Utility Model Registration] A braking device for mobile agricultural machinery in which the tilting of a brake operating lever operates a hydraulic cylinder connected to the valve via a hydraulic solenoid valve, which presses against a brake disc plate. The hydraulic cylinder is disposed in the transmission case, and the brake operating lever is further provided with a detection means for detecting the amount of tilting thereof, and the brake is turned on when the detected value increases. A braking device for a mobile agricultural machine, characterized in that the hydraulic solenoid valve is controlled in inching by increasing a time ratio.
