Abstract
A hedge cutting bar is shown and described as having rivets for securing a cutting blade between a retaining blade and a stationary blade. The rivet structure includes a central flange and distal hubs whereby the central flange may occupy slots in the cutting blade while the hubs attach within respective mounting apertures of the stationary blade and the retaining blade. The thickness of the flange is greater than the thickness of the cutting blade whereby a gripping force provided by the rivet is taken up at the flange to avoid pinching of the cutting blade between the stationary blade and the retaining blade. The described fastening arrangement is less suspectable to loosening under the vibrational forces imposed during use of the hedge cutting bar than that of prior fastening arrangements.
