ABSTRACT:
In a coupling hook for the lower links of a three-point linkage for connecting an agricultural implement to a tractor, side walls define the lateral confines of a pocket. The side walls are shaped to form a jaw into which a coupling element is seated. A latch within the pocket secures the coupling member in the jaw. A bottom wall extends across the lower ends of the side walls and forms a closure for the pocket. One of the side walls has an opening just above the bottom wall for removing dirt from the lower end of the pocket.
