A cutting head 300 comprises: a hydraulic ram 306 having an actuating piston 320 and an actuated piston 326, the working area of the actuating piston 320 being smaller than that of the actuated piston 326, an actuator 324 connected to the actuating piston 320 which urges the piston 320 towards the actuated piston 326, and a first jaw 330, which has a cutting surface and is connected to the actuated piston 326. Also included is a cutter (10 figure 1) for cutting bricks which comprises a first jaw (12 figure 1) and a second jaw (14 figure 1) positioned substantially opposite the first jaw (12 figure 1) and defines a receiving area for receiving a brick. A first cutting formation (24 figure 1) for engagement with a brick is defined on one of the first jaw (12 figure 1) and the second jaw (14 figure 1). Clamping means (16, 18 figure 1) connect the first jaw (12 figure 1) and the second jaw (14 figure 1) and are configured to move the second jaw (14 figure 1) towards the first jaw (12 figure 1). |
