Abstract: A seed belt cup planter includes seed-intercepting indexing pocket structure facing an adjacent cup on the downward run of the belt towards a furrow for orienting the seed released from the adjacent cup relative to the furrow. In one embodiment, the indexing pocket structure is located on the underside of the cups and receives and orients a cylindrically shaped seed such as a short sugar cane billet. The seed pickup side of the cup is shaped to efficiently receive cylindrical seeds as well as round and oval seeds of differing sizes from a seed puddle. A divider located in the seed hopper between adjacent columns of cups helps channel the seed to the cups and limits pressure on the seed puddle.

Abstract: An air divider having a shutoff plate for converting row spacing on a seeding implement. A reversible shutoff plate has a closed position wherein one end of the plate extends through a slot and completely blocks a leg of a Y-shaped output end of the divider. By reversing the shutoff plate, the leg is opened to air and material flow. The shutoff plate is retained in a clip or post adjacent the slot in both the closed and open positions. A seal closes the slot if the shutoff plate is not inserted and permits the shutoff plate option to be selected at any time.

Abstract: A seed cart for an air seeder is provided with pneumatic distribution system having a primary air distribution manifold. The primary air distribution manifold is provided with a top rank of venturis and a bottom rank of venturis for receiving an air stream from a blower which is divided into a top rank air stream and a bottom rank air stream. A selector valve is located above the top rank of venturis immediately below a product meter. The selector valve selectively directs metered product to either the top rank of venturis or the bottom rank of venturis. In a first position the selector valve directs metered product to the top rank of venturis in its second position the selector valve directs metered product to the bottom rank of venturis. Each selector valve is also provided with first and second air valves. In the selector valve's first position, the first air valve is open and directs air tapped from the top rank air stream to the product tank feeding product to the top rank of venturis.

Abstract: A mechanical seed meter having a stationary housing and a rotatable bowl. The stationary housing is provided with a first axial wall, an outer radial wall and a flexible inner radial wall. The bowl is provided with seed receiving cells that form a second axial wall for trapping singled seeds in the seed trapping area. A flexible and resilient flap maintains the seed in the seed receiving cells. An axially extending brush removes excess seeds from the seed receiving cells as they pass through the seed puddle before entering the seed trapping area. The seed slides along the radial outer wall by centrifugal force until it enters the outlet area from which the outer radial wall becomes part of the outlet and the metered seed is deposited through the outlet to a seed tube. Jammed seed, that is seed trapped in the seed receiving cells, are provided with a downward force by a bump located in the outlet and an upward force by a rotatable wheel located downstream from the outlet.

The bowl is provided with seed receiving cells that form an axial outer wall for trapping singled seeds in the seed trapping area. A flexible and resilient insert together with an axially extending brush removes excess seeds from the seed receiving cells as they pass through the seed puddle before entering the seed trapping area. The seed slides along the radial outer wall by centrifugal force until it enters the outlet area from which the radial outer wall becomes part of the outlet and the metered seed is deposited through the outlet to a seed tube.
