An anti-rotation pin structure for an agricultural implement includes a retainer laser cut from flat stock to include a pin-receiving opening with opposing grooves which are adapted to receive the ends of a cross pin. The retainer is secured to one side of support structure and receives a simple support pin having small bores extending diametrically through its ends. The cross pin is inserted through one of the bores with th e ends of the cross pin projecting radially outwardly a short distance from opposite sides of the support pin. The end of the support pin opposite the cross pin end is inserted throu gh the openings until the projecting cross pin ends seat in the opposing grooves. Thereafter , a quick lock pin is inserted through the bore in the end opposite the cross pin end to fix th e cross pin inside the pin retainer and lock the support pin against rotation.
