Power system having attachment-based engine control

A method of operating a power system in a machine, comprising:

• receiving operator input regarding operation of at least a first tool of a plurality of different tools that can be removably attachable to the machine, the at least a first tool being capable of consuming about 50% or more of a total engine power output of the machine;
• detecting attachment of the at least a first tool to the machine;
• based on the operator input, selectively increasing an engine power output of the machine when the at least a first tool is attached to the machine;
• and
• selectively decreasing the engine power output when the at least a first tool is not attached to the machine.

A machine, comprising

• an engine;
• a frame configured to support the engine and a plurality of different hydraulic work tools that could be removably attached to the machine, the plurality of different tools including at least a first hydraulic tool capable of consuming at least about 50% of a total power output of the engine;
• a system wiring harness having an indicator wire and a ground wire;
• at least one tool wiring harness associated with the plurality of different hydraulic work tools and configured to engage the system wiring harness;
• an operator input device controllable to affect operation of the plurality of different hydraulic work tools;
• and
• a controller in communication with the engine, the operator input device, and the system wiring harness, the controller being configured to:
• detect attachment of the at least a first hydraulic tool to the frame based a voltage between the indicator wire and the ground wire during engagement of the at least one tool wiring harness with the system wiring harness;
• selectively increase a power output of the engine when the at least a first tool is attached to the frame and the operator input device is manipulated by an operator of the machine to initiate a movement of the at least a first tool that the at least a first tool to consume at least the threshold amount of power;
• and
• selectively decrease the power output of the engine by about 10-30% when the at least a first tool is not attached to the frame, regardless of manipulation of the operator input device.
