Abstract
A meter roller is provided with a blank section for enabling an air seeder to achieve a substantially uniform seed rate throughout the width of the tillage. The fluted meter roller has a series of ridges spaced around its periphery, between which are located product receiving valleys. The blank section conforms to the fluted cross-section of the meter roller by projecting into the product receiving valleys of the meter roller. When a series of meter rollers is driven by a common shaft, the output of an individual meter roller may be modified by adjusting the number or size of blank sections attached to the meter roller.
