ABSTRACT:
Systems for reducing the possibility of inadvertent activation of an auger located in a supply body and/or spreader device while the covers of such a body or spreader device are open are provided. A motor that is drivingly connected to the auger is provided, as is a power supply for the motor that includes first and second engageable couplings. An arm located adjacent the spreader device is included, and is movable between a position that prevents opening of the cover and a position that permits opening of the cover. The first coupling is located with respect to the arm so that the first and second couplings may be engaged only when the arm is in a position that prevents the cover from opening. The cover can only be opened when the first and second couplings are separated, thereby interrupting the power supply to the motor and preventing operation of the auger.
