1. A system for earth moving machinery, comprising:
a plurality of wear elements adapted for coupling with digging implements of an earth moving machine;
one or more sensors for measuring forces, each sensor of the one or more sensors being arranged in a wear element of the plurality of wear elements either on an outer surface of said wear element or in a cavity formed on said outer surface; and
central control means comprising at least one processor and at least one memory for processing measurements of the one or more sensors in order to calculate force withstood by the wear elements;
wherein the central control means provide output instructions at least based on the processed measurements so that the output instructions comprise at least:
reducing a breakout force of the machine when the processed values exceed a predetermined excessive force threshold; and
increasing the breakout force when the processed values are less than a predetermined optimal force threshold; and
wherein the plurality of wear elements comprises at least one of: teeth, tooth bars, front guards, side guards, pins, clamps, or a combination thereof.
