An apparatus (30) for removing teeth (10) which are each disposed in a holder (12) of a trench digging apparatus comprises a tooth engaging part (36), a tube (34) which engages a respective holder (12), and a hydraulic arrangement whose cylinder (32) bears on the tube (34). The hydraulic arrangement acts by means of a piston (48) associated with the cylinder (32) to move the tooth engaging part (36) away from the holder (12), thus removing the tooth (10) from the holder (12). |
