Abstract: A control system that detects loosening of a vibrator component in a spreader system. As the vibrator loosens over time, it draws more current. Eventually, this excess current causes the vibrator motor to burn out. The control system detects the loosening of the vibrator to indicate a fault condition by measuring current increase in the vibrator, and then indicating a fault condition that the bolts must be tightened, which results in lowering of the current draw, thereby protecting the vibrator motor from burnout. The system has a “learning mode” capable of establishing and memorizing a baseline of current draw suitable for a vibrator. In this way, a current threshold is exceeded over time, which indicates loosening of the vibrator. The baseline level can be selectively changed adapted with changing conditions, or adapted to other types of systems besides spreader vibrators.

Abstract: Provided in this disclosure is a control system and method that monitors current in a spreader motor to accurately detect a mechanical overload condition. The invention distinguishes between a short duration high current transient spike caused by sparking of brushes in the DC motor, and a long duration continuous high current caused by a mechanical overload condition in the DC motor. The control system momentarily deactivates and reactivates the motor. If high current is no longer detected, the control system construes this as a transient spike and no fault condition is indicated. If high current persists, the control system construes this as an actual overload condition, and a fault condition is indicated to the operator. In this manner, a selected default current level can be established in the control system which can be selectively reestablished if conditions within the device change over time.

Abstract: Provided in this disclosure is a slam latch for attaching a chute to a hopper mounted onto a vehicle. A cover is secured to an exterior surface of the hopper and defines a void therebetween. First and second aligned holes are formed in the cover and the hopper. A pin is mounted to the cover for movement through the first and second holes and urges with a spring. A plunger is retained in the void and moves between a closed position that blocks the pin from engagement with the holes, and an open position that admits the pin for engagement. The chute includes an engagement member having a third hole. The chute is displaced such that the engagement member slides into the void and displaces the plunger, enabling engagement of the pin with the first, second and third holes, thereby attaching the chute to the hopper.

Abstract: A material spreader is mountable to a rearwardly projecting bumper of a vehicle for conveying and spreading material, the vehicle including a rearwardly projecting hitch receiver. The material spreader includes a hopper for holding material to be spread, a frame supporting the hopper and having a forwardly projecting hitch mount configured for coupling to the rearwardly projecting hitch receiver of the vehicle, and a support member having an underside for resting atop a top surface of the bumper, the support member being movable vertically relative to the frame. A tie down is connected to the support member and the frame for urging the support member and the hitch mount towards one another to effect a clamping action on the receiver and the bumper. The material spreader also includes a dual hinged lid and a gear box for driving a spinner and an auger.

Abstract: A tailgate assembly includes a talegate and latch assembly. The tailgate is moveable between open and closed positions. The latch assembly includes an actuator, a latch, and a stopper. The actuator is operative to move the latch between an unlatched position where the latch allows movement of the tailgate from the closed position, and a latched position where the latch prevents movement of the tailgate from the closed position. The stopper is responsive to movement in the actuator to move between a nonstopping position and a stopping position. In the stopping position, the stopper prevents the latch from moving from the latched position to the unlatched position other than by the actuator.

Abstract: A spreader assembly for spreading sand or salt comprised of a molded, double-walled hopper having a bin portion and leg portions. The hopper has an inner wall and an outer wall, wherein the inner wall has a front end section and opposing side sections. The end sections and the side sections define a media-holding chamber within the bin portion of the hopper. The chamber has a generally rectangular upper portion, a funnel-shaped lower portion and a bottom having an opening extending through the bin portion. The funnel-shaped lower portion of the chamber slopes toward the opening. The outer wall of the hopper defines the leg portions, and the leg portions are dimensioned to extend below the opening in the bin portion.
