The invention discloses a tractor electronic control shifting device based on laser beam sensors and a method. The device comprises a controller, a touch screen display, the laser beam sensor I, the laser beam sensor II, the laser beam sensor III and an electric push rod. When shifting needs to be conducted, an operator inputs required gear information through the touch display screen, then the electric push rod is enabled by the controller to push a shift lever to move, voltage signals fed back by the laser beam sensor I, the laser beam sensor II and the laser beam sensor III are received bythe controller in real time in the moving process of the shift lever, when the shift lever reaches the required gear, laser of the laser beam sensor corresponding to the gear is blocked, thus, the voltage signal fed back by the laser beam sensor is changed, the electric push rod is stopped operating by the controller at the moment, and the shifting process is completed through the shift lever. Theshifting process can be c
