Having arthritis in his hands, Mt. Sterling, KY, farmer Buck Trimble invented a tool that he uses to remove clip pins and lynch pins from his tractor drawbar and three-point hitch when changing implements. It's simply a slim, long-necked, rubber-handled screwdriver with the tip of the blade bent around to form a hook, which he inserts under the pin head to pull it out. The screwdriver stays with the tractor on a small hook he mounted on the rear fender.
