The Roughneck Ground Breaking Bar is ideal for use in locations and jobs where a normal crowbar is not sufficient or a pick not accurate enough. This heavy-duty bar is made up of an inner solid crowbar with a chisel tip, drop forged, heat treated and hardened. A weight slides up and down the central bar and exerts blows on the target material. It is ideal for breaking up hard ground, rocks, concrete slabs, asphalt etc. For extra impact, the end stopper can be removed to allow the weight to drop from a greater height.
