A farm machine coupling utilizes a wedge having an internally threaded bore formed therein for accommodating a bolt threadedly coupled in a coupling member of a shank affixed to a farm machine. When the coupling end of an agricultural attachment for performing an agricultural task is positioned on the free end of the shank and the wedge is positioned in the rectangular sleeve type coupling end next-adjacent the shank and the bolt coupled in the coupling member is threadedly coupled in the wedge, the attachment is removably tightenable on the shank via the bolt and the wedge.
