Abstract
A self propelled continuous mining machine includes a mobile frame assembly having a first pivot point for a boom assembly or an end of a piston cylinder assembly and a second pivot point for pivotally connecting an end of a piston cylinder assembly or pivotally connecting an end portion of a lever member which may be interchangeably utilized to provide the continuous mining machine with boom assemblies of different cutting heights. The first pivot point is located at an elevation higher than the elevation of the second pivot point. This arrangement of interchangeable boom pivot points permits for low and high cutting height boom assemblies to be utilized with the same continuous mining machine.
