たことを特徴とする動力伝達制御装置。(1) In a power transmission device for a self-propelled vehicle that transmits prime mover power to a traveling device via a hydrostatic transmission, detecting whether an acceleration/deceleration controller of a hydraulic pump provided in the hydrostatic transmission is in neutral. and a switch that detects the presence or absence of a control operation by the service brake, and a switch that opens when the non-neutralization of the acceleration/deceleration controller and a braking operation by the service brake are detected by these switches. A valve is interposed in parallel with the hydraulic motor of the hydrostatic transmission circuit, and when the hydraulic motor is in a driving state, that is, when the acceleration/deceleration controller is other than neutral, when a braking operation by a service brake is performed. A power transmission control device, characterized in that power transmission from the prime mover to the traveling device is stopped by opening the switching valve, and the vehicle can be braked by a brake device. （２）前記スイッチは直列に接続されていることを　−
