A system for transmitting power from a drive shaft to a seed meter shaft of a seeder, comprising: a first transmission including: a first transmission coupling connected to one of the drive shaft and the seed meter shaft so as to rotate as the one of the drive shaft and the seed meter shaft rotates; a first connecting member of a first connection interface; a clutch assembly including: a first clutch coupling connected to the first transmission coupling so as to rotate as the first transmission coupling rotates; a second clutch coupling; a clutch connecting the first clutch coupling and the second clutch coupling such that the second clutch coupling is selectively connected to the first clutch coupling so as to selectively rotate as the first clutch coupling rotates; a second connecting member of the first connection interface, the second connecting member matingly engaging the first connecting member to secure the first transmission to the clutch assembly; and a first connecting member of a second connection interface; a flexible shaft assembly including: a first shaft coupling connected to the second clutch coupling so as to rotate as the second clutch coupling rotates; a flexible shaft connected to the first shaft coupling so as to rotate as the first shaft coupling rotates; and a second shaft coupling connected to the flexible shaft so as to rotate as the flexible shaft rotates; a second connecting member of the second connection interface matingly engaging the first connecting member of the second connection interface to secure the flexible drive shaft assembly to the clutch assembly; a second transmission including: a second transmission coupling connected to the second shaft coupling so as to rotate as the second shaft coupling rotates, and the second transmission coupling being connected to the other of the drive shaft and the seed meter shaft so as to rotate as the other of the drive shaft and the seed meter shaft rotates; wherein the second connecting member of the first connection interface is detachable from the first connecting member of the first connection interface and the second connecting member of the second connection interface is detachable from the first connecting member of the second connection interface, and the second connecting member of the second connection interface is matingly engageable with the first connecting member of the first connection interface to secure the flexible shaft assembly directly to the first transmission and directly connect the first transmission coupling and the first shaft coupling. a first transmission including: a first transmission coupling connected to one of the drive shaft and the seed meter shaft so as to rotate as the one of the drive shaft and the seed meter shaft rotates;
