Abstract

A feedback system for a machine operation that includes a first quantitatively measurable task and a second quantitatively measurable task. A controller stores a first threshold for the first quantitatively measurable task, stores a second threshold for the second quantitatively measurable task, determines the first operating characteristic of a first linkage member, compares the first operating characteristic to the first threshold, and generates and displays a first rating for the first quantitatively measurable task. The controller also determines the second operating characteristic of a work implement operatively connected to the first linkage member, compares the second operating characteristic to the second threshold, and generates and displays a second rating for the second quantitatively measurable task based upon the second operating characteristic and the second threshold.
