A clutch unit is mounted inside the row unit so that it is protected against contact and damage by crop debris and other material passing by the planting implement. An input of the clutch driven off of the drill shaft of the planting implement and an output of the clutch is operably connected to the seed meter so that operation of the clutch unit interrupts dispensing of seed by the seed meter.
