Abstract
The present invention is an air separation tube for an agricultural planter. The air separation tube comprises a hollow tube having an inlet and outlet that is mounted to the side wall of a mini-hopper. The tube is provided with a downwardly curving bend having a screen through which air is allowed to pass. The screen prevents the seed carried by the air stream from leaving the tube. The outlet of the tube is located above the seed puddle of the seed meter which is coupled to the mini-hopper.
