Abstract
A safety interlock system is disclosed that can be selectively actuated to prevent or enable access to a conveyor mechanism of a spreader. When actuated to prevent access, the safety interlock prevents a top cover from moving to a position that allows access to the conveyor through an open top of the trough and prevents a hopper door from moving to an opened position wherein an operator can access the conveyor mechanism through a bottom opening of the trough. The safety interlock system can be configured such that a hydraulic drive motor is disconnected from the conveyor mechanism before allowing the top cover and the door to move to positions providing access to the conveyor mechanism.
