The present invention relates particularly to an articulating mounting for positioning a rock saw for cutting rock, in particular for the building industry. Rock saw mountings are known which enable mounting of a rock saw blade to an hydraulic arm of a conventional excavator. Conventionally, the rock saw is mounted so it is fixed to either one side or other of the hydraulic arm. The angle of the rock saw relative to the hydraulic arm cannot be varied. The present invention provides a mounting which enables three degrees of freedom of motion of the rock saw, to enable it to be fixed at predetermined angles to make predetermined desired angular cuts into rock. The rock saw may be moved from one side of the arm to the other in order to cut trenches without it being necessary to reposition the excavator. The mounting may also be used as a support for tools other than a rock saw.
