The plow on this Jeep is made of steel, and had a replaceable edge on the botom. It weighs about 300 pounds. As for the mounting: There is an "A" frame that attaches to the front frame rails near the suspension mounts and a support that is bolted to the frame rails behind the bumper, with a chain welded to the "A" frame (for an ajustable preset height). The system uses a power up, gravity down hydraulic lift with manual (pin) angle settings. Modern snow plows use hydraulic systems to raise, lower, and set the angle.
