Flow splitter and agricultural implements having flow splitters

An agricultural implement, comprising:

• a frame;
• a toolbar carried by the frame and supporting a plurality of row units;
• a hopper carried by the frame;
• a primary flow line connecting the hopper to a flow splitter, the flow splitter comprising:
• a body having a generally cylindrical main passage therethrough oriented along a longitudinal axis of the body, the body having an upstream end and a downstream end, wherein:
• the main passage connects an inlet at the upstream end to exactly three split passages adjacent the downstream end, each split passage connected to a corresponding outlet;
• a first and second of the three split passages are oriented along axes that intersect one another at a first acute angle in a common plane with the longitudinal axis;
• and
• a third of the three split passages intersects the common plane at a second acute angle;
• and
• three secondary flow lines connecting the flow splitter to three row units of the plurality of row units.
