Accelerator control device and agricultural machine

The invention relates to an accelerator control device and an agricultural machine. The accelerator control device comprises a hand and foot accelerator duplex module, an accelerator connection rod, asignal variable sensing module and an ECU electric control module, wherein the hand and foot accelerator duplex module is connected with the signal variable sensing module through the accelerator connection rod; and the signal variable sensing module is connected with the ECU electric control module. Under the function of external force, the hand and foot accelerator duplex module controls the accelerator connection rod to move, the signal variable sensing module receives position movement signals generated when the accelerator connection rod moves and converts and processes the signals to output electric signals to the ECU electric control module, and the ECU electric control module controls an accelerator according to the received electric signals. Through the hand and foot acceleratorduplex module, the accelerator connection rod and the signal variable sensing module, the mechanical control signals transmitted by the accelerator connection rod are converted into the electric signals, and accurate control over accelerator oil jetting is achieved through the ECU electric control module, so that the stable control over the speed of an engine is achieved, the design of a complex independent electronic hand and foot accelerator is avoided, the structure is simple, and the accelerator control is accurate.
