Abstract
A seeding machine having a plurality of seed meters receiving rotary input from a common input shaft. First and second gearboxes respectively connect the common rotary input to individual seed meters. A flexible drive extends from the gearbox adjacent the common rotary input to the seed meters. Spring clutches, normally connected, are electrically actuated to disengage the drive to the individual seed meters. The clutches may be integrated in the gearbox adjacent the rotary drive or the gear box for the individual seed meters.
