Tool attachments on an auto-powered mobile machine

A tool carrying and controlling system wherein an operator can control a first swiveling tool and either a second controllable tool or a third controllable tool to operate in coordination with the first tool, comprising:

• (a) a set of wheels or tracks on which the machine rides supporting a support structure;
• (b) coupled to and supported by the support structure, an operator's seat and operator's controls;
• (c) coupled to and supported by the support structure, a vertical swivel such that components coupled to an upper side of the swivel can swivel about a vertical axis relative to the support structure;
• (d) an articulating arm coupled to the upper side of the vertical swivel, controllable by the controls, with a first tool mounted on a distant end of the arm;
• (e) coupled to and supported by the support structure and fixed to a lower side of the swivel, a mounting base for mounting an additional tool;
• (f) a second tool mountable on the mounting base, the second tool or mounting base including moving parts such that an operator can, using controls at the operator's seat, control the first tool, which can swivel, and, also using controls at the operator's seat, control the moving parts of the second tool or mounting base, which does not swivel with the first tool, so that the two tools perform an operation in coordination with each other;
• and
• (g) a third tool mountable on the mounting base, the third tool or mounting base including moving parts controllable by the controls such that an operator can remove the second tool and replace it with the third tool and then, using controls at the operator's seat, control the first tool, which can swivel, and, also using controls at the operator's seat, control the moving parts of the third tool or mounting base, which does not swivel with the first tool, so that the two tools perform an operation in coordination with each other.
