The invention discloses a field edge operation control system (10) for controlled operation of a plurality of mechanisms (16, 18, 20) related to a vehicle. The field edge operation control system (10) comprises a controller (12) configured to process input signals (In1, In2, In3 and In4), and the input signals (In1, In2, In3 and In4) are from a speed measurement device (S1) detecting a predetermined minimum ground speed and sensors (S2, S3 and S4) associated with the corresponding mechanisms. When a vehicle ground speed is detected to be greater than the predetermined minimum ground speed, the controller triggers an actuating component (14) to be capbel of moving from a working position to a non-working position. According to the non-working position and the working position of the actuating component (14), the controller (12) processes the signals (In2, In3 and In4) from the sensors (S2, S3 and S4) and then generates output signals (Op2, Op3, Op4) to trigger desired operation of the mechanisms (16, 18, 20).
