Abstract
Abstract A curved plate extending the width of the bucket is relatively fixed with respect to the boom so that as the bucket is rotated the size of the opening between the bucket and plate can be varied to control the rate of flow of material from the bucket. A funneling mechanism directs the material dispensed from the bucket to a restricted material discharge opening.
