Abstract: This invention relates to a mineral-cutting machine, the overall length of which can be substantially reduced, comprising a body and a ranging arm mounted for pivotal movement with respect to the body. A cutting device is supported on the ranging arm for rotation about an axis extending away from the ranging arm in a direction transverse to the intended direction of movement of the machine during a cutting operation. The cutting device is normally in a position at least partly beyond an end of the body during a cutting operation, and means are provided for moving the cutting device from said normal position at least partly beyond an end of the body to a position where it is at least substantially wholly alongside of the body.
