Abstract:
A control system for automatically controlling a work implement of an earthmoving machine having wheels, said work implement including a bucket, to capture, lift and dump material, said bucket being controllably actuated by a hydraulic tilt cylinder and at least one hydraulic lift cylinder, said system comprising:a torque indicating mechanism that provides a representative value for an amount of torque applied to said wheels of said earthmoving machine; an electronic controller for receiving said representative torque value from said torque indicating mechanism and determining if said representative value of torque received from said torque indicating mechanism exceeds a first predetermined value and then responsively generating a first command signal; and a hydraulic implement controller for controlling hydraulic fluid flow to said hydraulic tilt cylinder in a predetermined sequence activated in response to said first command signal with said hydraulic tilt cylinder controllably actuating said bucket of the earthmoving machine in order to remove material from a pile.
