An anti-slabbing device pivotally coupled above a material conveyor and configured to drop down onto material conveyed and further configured so as to vibrate the leading edge of the material as it reaches the end of the conveyor to create a more consistent flow of material from the end of the conveyor down onto a spinner for distributing the material.

We claim: 1. A method of improving flow rate uniformity of material flowing to a spinner spreader with controlled capacity for impeding flow and a concomitant increased ease of passing debris which might otherwise interfere with uniformity of flow of the material, comprising the steps of: providing a conveyor for transporting material outwardly from a storage container which is carried upon a wheeled vehicle; conveying material by the conveyor; providing a spinner, below the conveyor, configured for distributing the material after the material falls off an end of the conveyor; allowing the material to drop from the conveyor onto the spinner where it is distributed; providing a pivoting vibrator assembly, disposed at least in part above portions of the conveyor and in contact with the material, while the material is being conveyed by the conveyor; causing the pivoting vibrator assembly to vibrate, and thereby increase a flow consistency of the material on to the spinner; configuring the pivoting vibrator assembly for and allowing the pivoting vibrator assembly to automatically pivot upwardly, as a result of a change in matter coming in contact with the pivoting vibrator assembly, and thereby increasing a gap through which the matter can drop below the conveyor; and wherein said pivoting vibrator assembly further comprises: a spaced apart array of a plurality of longitudinally rigid cutting inner blades, each inner blade comprising: a proximal end and an opposing distal end, where the proximal end is nearer an axis or rotation about which the pivoting vibrator assembly pivots and the distal end has a free end; a cutting edge, disposed between the proximal end and the distal end, for cutting into the material as it flows toward an end of the conveyor; a means for preventing the plurality of inner cutting blades from contacting a moving surface of the conveyor; and a vibrator coupled to and configured for vibrating the cutting inner blades at a predetermined vibrating frequency.
