Systems and methods of controlling a vibrating screed. One vibrating screed includes a screed member, a motor configured to vibrate the screed member, and a speed sensor configured to output speed signals indicative of a motor speed. A controller is connected to the speed sensor and the motor. The controller is configured to drive the motor according to a speed command, receive the speed signals from the speed sensor, determine whether the motor speed is less than or equal to a speed threshold, and terminate, in response to the motor speed being less than or equal to the speed threshold, operation of the motor.
