Abstract
A method for automatically determining the productivity of an earthmoving machine in real time using an onboard computer. The earthmoving machine operates in cycles having a first portion and a second portion. The earthmoving machine moves in a first direction during the first portion and in a second direction during the second portion. The method includes the steps of detecting the starts of each cycle for a series of cycles, determining a machine parameter corresponding to each cycle, calculating a cycle parameter as a function of the machine parameter, and calculating at least one measure of productivity as a function of the cycle parameter.
