Abstract: A system for changing seed variety on a planter includes a plurality of row units with each row unit having a plurality of seed meters. Each seed meter has a guide for delivering seed to a transport belt and a switch that is activated and deactivated by a switch actuator on the belt. The belt has adjustable sidewalls, cover, and lugs.

Abstract: A sealing system for the shoe (20) in a combine harvester is disclosed wherein the separate flow areas in the shoe (20) are sealed from one another. The sealing system (1110) discourages air from traveling through the components of the shoe other than the sieve system, thereby providing flow of air to the sieves (25). The positive differential and the containment of air in the shoe (20) are accomplished by providing one or more seals (114, 116) between the moving shoe components and the stationary frame components. In those combines including self-leveling shoe assemblies, the distance between the shoe assembly (20) rolls to maintain level operation. Various embodiment of this invention provide for sealing this change in the dimensions as the shoe moves.
