description A boring machine for boring a hole in the earth comprises a cutter head, a cutter head support which supports 5 the cutter head and a rear part which is provided with movable rear part grippers for temporarily fixing the rear part with respect to its surroundings. The cutter head and the rear part are located at opposite sides of the cutter head support and the cutter head is rotatable with respect to the cutter head 10 support about an axis of rotation. The cutter head support and the rear part are coupled to each other by a thrust mechanism and a hinge including a single pivot point. The hinge is translatable with respect to one of the cutter head support and the rear part along an axis of translation which extends 15 through the pivot point and has at least a component that coincides with the axis of rotation. The thrust mechanism drivably engages at least one of the cutter head support and the rear part at a distance from the axis of rotation and the axis of translation, respectively.
