A grab for a sugar can loader suspended from the boom of a tractor having an improved fastening system formed of two mechanical arms that automatically elevate the grab during its closing movement, so that the tips of the grab's tines trace a path parallel to and along the surface of the ground. This avoids ground penetration by the grab's tips, decreasing the pick up of soil and other undersirable materials with the can during its loading.
