A material-conveying system has a material-conveying apparatus for conveying material, an electronic control unit, a user interface control panel mounted to the apparatus and interfaced with the electronic control unit to receive user input commands to control the apparatus, a power unit mechanically coupled to the apparatus for powering the apparatus, a data bus communicatively connected between the power unit and the control unit, a portable remote control device for wirelessly transmitting command signals for remotely controlling a power output of the power unit to the apparatus, a wireless receiver at the apparatus for receiving the command signals from the portable remote control device and for transmitting the command signals to the electronic control unit that controls the power output of the power unit. The portable remote control device is also configured to wirelessly transmit a control signal to a gate controller of a material-unloading gate of a material container.
