Abstract
A ball coupling includes a tractor drawbar mounted hitch ball, substantially englobed by a cap assembly which is slidable on the hitch ball. The cap assembly includes a cap having a frusto-conical surface which non-rotatably engages a frusto-conical through opening in an implement drawbar attached adapter. A lockable fastener abuts the adapter and protrudes into the smaller base of the adapter opening and threads into a threaded hole in the smaller base of the cap to draw the cap assembly into the adapter.
