An apparatus for transmitting power from a drive shaft (24) to a seed meter shaft of a seed metering device includes a transmission (26). A transmission housing (28) has a first housing section (30) and an identical second housing section (30). The first housing section (30) and the second housing section (30) together define a first internal passageway (44) and a second internal passageway (50). The transmission further includes a first transmission element (46) rotatably supported by the first housing section (30) and the second housing section (30) in the first internal passageway (44). The first transmission element (46) connects to one of the drive shaft (24) and the seed meter shaft. The transmission further includes a second transmission element (54) rotatably supported by the first housing section (30) and the second housing section (30) in the second internal passageway (50). The second transmission element (54) engages the first transmission element (46) and connects to the other of the drive shaft (24) and the seed meter shaft.
