Abstract:
A row control system for a seed planter: a transverse frame for coupling with a tractor; a plurality of seed metering units carried by and laterally spaced on the frame operated from a fluid source connected to an elongated manifold carried by and extending along said frame and having outlets adjacent each of said seed metering units; a first fluid line having one end fluidly connected with an associated outlet on the manifold; a plurality of valve members carried on the frame adjacent an outlet on the manifold; first means for fluidly connecting the other end of each first fluid line to an outlet of a valve member; second means for fluidly connecting an inlet of said valve member with an associated outlet on the manifold; actuator means for selectively moving each said valve member between an open position and a closed position; and control means operatively connected to said actuator means for selectively moving said valve member between said open position and said closed position.
