The invention provides a tractor front axle suspension system and method. A front axle suspension system of a tractor is characterized in that a third electromagnetic directional valve is connected with a first electromagnetic directional valve and a second electromagnetic directional valve, and the first electromagnetic directional valve and the second electromagnetic directional valve are connected with a first throttling hole and a second throttling hole; the first throttling hole, the second throttling hole, the first pressure sensor and the second pressure sensor are connected with a first cavity of a front axle left side supporting oil cylinder and a front axle right side supporting oil cylinder, and the first one-way valve and the second one-way valve are connected with the first throttling hole and the second throttling hole in parallel. One end of the pressure reducing valve and the second energy accumulator are both connected with a pipeline between the second throttling hole and the front axle right side supporting oil cylinder, and the first energy accumulator is connected with a pipeline between the first throttling hole and the front axle left side supporting oil cylinder. The first pressure sensor, the second pressure sensor, the first electromagnetic directional valve, the second electromagnetic directional valve, the third electromagnetic directional valve, the vehicle speed sensor and the angle sensor are all connected with the whole vehicle control device.
