The invention relates to a method for operating a hybrid drive embodied as a parallel hybrid drive and comprising a drive train, especially for a motor vehicle, and comprising at least one internal combustion engine and at least one electrical machine device or a hydraulic machine device. A disengaging clutch is arranged between the internal combustion engine and the electrical or hydraulic machine device, and the electrical or hydraulic machine device is arranged downstream of the internal combustion engine in the direction of output. The disengaging clutch is disengaged during the towing mode when a predeterminable towing torque can be received by the electrical or hydraulic machine device.
