Patent ID: 7922438

Claim:
A method of operating a working machine including a body and a ground engaging structure, the body mounting a prime mover and a first working arm which is pivoted for up and down movement about a first generally horizontal axis, the first working arm extending beyond a first end of the body and carrying in use, at its outermost end, a mounting structure releasably carrying a first working implement, and the body carrying towards a second end of the body opposite to the first end, a superstructure which is rotatable relative to the body about a first generally upright axis, the superstructure providing a mounting for a second working arm, which permits the second working arm to be pivoted up and down about a second generally horizontal axis and to be rotated about a second generally upright axis, and a second working arm in use, carrying at an outermost end, a mounting releasably carrying a second working implement, the second working arm including a boom which is mounted to the superstructure at one end, and to one end of a dipper at or adjacent the other end, the dipper being pivotal relative to the boom at a first end of the dipper, about a further generally horizontal axis and carrying at a second end thereof, the mounting for the second working implement, the machine further including a third implement carried at the second end of the body, the third implement being provided on a further mounting structure to provide a further mounting assembly, the assembly being capable of mounting the first working implement, and the method including manipulating the second working arm to move the mounting for the second working implement to the mounting structure carrying the first working implement, releasing the engagement between the mounting structure of the first working arm and the first working implement, transporting the first working implement by manipulating the second working arm and the mounting for the second working implement, to bring the first working implement to the further mounting assembly, and engaging the first working implement with the further mounting assembly so that the first working implement is carried by the further mounting assembly, and using the first working implement when carried by the further mounting assembly to perform working operations.
