The invention relates to the field of vehicle transmission device arranging or installing, and in particular to a ground clearance adjusting lifting system of a four-wheel tractor. The ground clearance adjusting lifting system comprises a closed upper tank and a closed lower tank. The upper tank is located above the lower tank. The ground clearance adjusting lifting system further comprises a lifting rod. The upper tank and the lower tank are connected through the lifting rod. A tank flange is arranged on one side edge of the upper tank, and a fixing base is arranged on the corresponding other side edge of the upper tank. The upper tank is internally provided with a third bevel gear and a fourth bevel gear. The crossed axis angle of the third bevel gear and the fourth bevel gear is 90 degrees. The third bevel gear and the fourth bevel gear are engaged. The fourth bevel gear is fixedly connected with a drive shaft. The third bevel gear is in sliding connection with the lifting rod. After the system is installed on the four-wheel tractor, the ground clearance of the four-wheel tractor can be greatly increased and can be freely adjusted.
