Seed metering device for agricultural seeder

A seed metering device for an agricultural seeder, comprising:

• a meter housing having a seed pool area and a seed delivery opening that allows a supply of seed to be delivered into the seed pool area;
• a seed disk covering an open side of said meter housing, said seed disk having a series of pockets spaced around an outer circumference thereof, said seed disk being mounted on a center shaft that provides driving force to rotate the seed disk relative to the meter housing, said seed disk being arranged so that as the seed disk rotates the pockets of the seed disk pass through the seed pool and pick up seeds;
• and
• said seed meter housing having a sloping back wall in the seed pool area, said sloping back wall being arranged so that a gap between the seed disk and the back wall increases in a direction of disk rotation within the seed pool area to ensure that no binding or pinching of seeds will occur between the seed disk and the back wall.
