Abstract

In a mineral-cutting machine 1 having a body 3 and a ranging arm 4 mounted for pivotal movement with respect to the body a cutting device 6 is supported on the ranging arm for rotation about an axis 7 extending away from the ranging arm in a direction transverse to the intended direction of movement of the machine during a mineral-cutting operation and the driving motor 10 for rotating the cutting device is at least substantially wholly contained within the cutting device. <IMAGE>
