A dry matter dispensing device comprising a hopper having a paddle pivoted between the front and rear walls, the paddle is oscillated to sweep the contents from the opposite ends of an arcuate, concave tray with each stroke thereof. The dry material slides down a pair of adjustably sloped panels on opposite sides of that paddle so that, as the paddle sweeps material in front of it on each stroke, more is dropping down the sloped panel behind it to pile up on the concave tray. Hence, a measured amount of the dry material is delivered by setting the length and number of paddle strokes. The adjustment of the sloping panels is made to ensure free flow to the concave tray without the material bridging or escaping prematurely from the tray.
