ABSTRACT:
The selective creation of tramlines is disclosed where the metered seed normlly 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, 30c) 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). In the preferred form, the diverting hose (44, 54, 56) from the butterfly valve (26) may extend through the housings (24) and be in direct communication with adjacent row planter units (20a, 20c) or may be connected to Y-shaped connectors (46) having a passage (50) intersecting with the passage (48) that the metered seed for the adjacent row planter units (20a, 20c) would normally pass for mixing the metered seed. A divider (52) may be provided for dividing the metered seed diverted by the butterfly valve (26) between the two adjacent row planter units (20a, 20c).
