Patent attributes
An agricultural planter includes a chassis, a pneumatic system carried by the chassis, and a row unit carried by the chassis. The row unit includes a unit body, a metering unit carried by the unit body, a flexible coupling locked onto the port by an inner lip formed on an inner surface of the coupling. The metering unit includes a port with a channel formed within the port. The coupling has a sliding region formed on an outer surface of the coupling. The row unit also includes a locking ring bound within the sliding region of the coupling. The locking ring is slidable across the sliding region between a locked position and an unlocked position, such that the locking ring prevents the coupling from deforming to allow the inner lip off the port in the locked position. The row unit also includes a hose connecting the pneumatic system to the channel of the port through the coupling.
