The invention discloses a fault detecting and handling method for automatic shifting of an electric tractor. A remote control unit screen, a remote control unit master chip, a transmitting unit, a receiver, a vehicle control unit (VCU), an H-bridge, an actuating mechanism electric push rod and a shift lever are comprised; the actuating mechanism electric push rod and the shift lever are connectedand a pressure sensor is arranged therebetween; the output end of the remote control unit screen is electrically connected with the input end of the remote control unit master chip; the output end ofthe remote control unit master chip is electrically connected with the input end of the transmitting unit; the output end of the transmitting unit is electrically connected with the input end of the receiver; the output end of the receiver is bidirectionally connected with the input end of the VCU; the output end of the VCU is electrically connected with the input end of the H-bridge; and the output end of the H-bridge is electrically connected with the input end of the actuating mechanism electric push rod. The fault detecting and handling method for automatic shifting of the electric tractoreffectively avoids the conditions that a fault cannot be handled in time and the shift lever is damaged during automatic shifting.
