ABSTRACT:
A clutching mechanism for a seed meter incorporates a spring wrapped clutch for selectively disengaging a seed meter on a seed drill in order to tramline fields for agricultural purposes. A common shaft rotates and dispenses seeds from a series of seed meters on the drill. The spring wrapped clutch of the present invention allows for disengagement of singular meters from the rotational actuation of the common shaft. The seed metering clutch incorporates a rotatable drum which dispenses the seed as it is turned. The drum is attached to a driven element which is further attached to a spring. The spring compressibly holds a driving element attached to the rotatable shaft. Seals on the clutch prevent intrusion of foreign matter such as soil into the interior clutch. A selective engagement of the spring causes a decompression on the driving element and consequently, stops the rotation of the seed drum within the seed meter.
