A push-pull force control method for a horizontal directional drilling machine with the following steps is provided. According to a correspondence relationship between a motor displacement and a maximum push-pull force of a drilling machine, the motor displacement is first adjusted, so that the required push-pull force can be obtained through the adjustment of the subsequent steps. Then, an oil feeding pressure of the motor is controlled according to a relationship between the push-pull force and the working pressure difference of the motor. Finally, the push-pull force of the motor is controlled in real time according to the oil feeding pressure of the motor to be equal to the required push-pull force value.
