  • Diverting valve usable in apparatus for selectively creating tramlines
    Patent number: 5265547
    Abstract: The selective creation of tramlines is disclosed where the metered seed normally delivered through the outlet hose (18b) of the row planter unit (20b) corresponding to the desired location of the tramline is diverted by a butterfly valve (26) to one or both of the row planter units (20a, 20c) located adjacent to and on opposite sides of the row planter unit (20b). The butterfly valve (26) includes an inlet conduit (28) which intersects with first and second outlet conduits (30, 32) and a butterfly element (34) which is pivoted by a solenoid actuator (40) against the bias of a spring (36) to selectively block one of the outlet conduits (30, 32).
