The invention relates to an agricultural four-wheel-drive self-adaptive chassis with a rigidity-adjustable damping mechanism. The agricultural four-wheel-drive self-adaptive chassis comprises a vehicle body and an independent suspension system. The vehicle body comprises a vehicle body and a rack; the independent suspension system comprises suspension damping devices arranged on the front side and the rear side of the vehicle body. The suspension damping device comprises a suspension device and a damping device. The suspension device comprises a parallel four-bar profiling mechanism; the damping device comprises a spring damping shock absorber and an air spring system; the air spring system comprises an air spring, an additional air chamber, an inflator, a height adjusting valve and a connecting pipeline; the upper end of the spring damping shock absorber is hinged to a vehicle body, and the lower end of the spring damping shock absorber is hinged to a first connecting rod in the parallel four-rod profiling mechanism. According to the agricultural four-wheel-drive self-adaptive chassis, the trafficability of an agricultural unmanned vehicle is improved, meanwhile, the impact of an uneven road surface on a vehicle body can be reduced, and the application range of the agricultural unmanned vehicle is widened.
