A flexible endless belt mountable on rotating elements has an outer and inn er surface between first and second lateral edges and a plurality of longitudinally spaced-apart laterally oriented upraised flights on the outer surface. Each flight has a single medial portion offset in a rearward longitudinal direction from portions of the flight immediately lateral to the medial portion. Protrusions on the inner surface engage the rotating elements for endlessly rotating the endless belt in a forward longitudinal direction. Such an endless belt is particularly useful on a control apparatu s for a stone slinger.
