The invention discloses an agricultural machine and an automatic gear shifting device and automatic gear shifting method thereof. The automatic gear shifting device is used for adjusting the gear engagement position of a gearbox of the agricultural machine. The gearbox comprises a driven gear set. The driven gear set is provided with a transmission shaft, a gear shifting rod and a gear shifting gear, wherein the gear shifting gear is installed on the transmission shaft in a sleeving manner and installed at the gear shifting end of the gear shifting rod in a driven manner. The automatic gear shifting device comprises a driver and a swing arm. The swing arm is provided with an adjusting end and a driven end corresponding to the adjusting end. The driven end of the swing arm is installed on the driver in a driven manner. The free end of the gear shifting rod is installed at the adjusting end of the swing arm in a driven manner. The swing arm is arranged in the manner that the middle portion of the swing arm is allowed to rotate around a fixing shaft when the driver drives the driven end of the swing arm.
