Abstract:
A control system for use on work machines having ground engaging propulsion mechanisms on a left side and a right side of said machines, comprising:a first motor associated with said left ground engaging propulsion mechanism; a first speed sensor associated with the ground engaging propulsion mechanism on the left side of the machine, said first speed sensor producing a left propulsion speed signal; a second motor associated with said right ground engaging propulsion mechanism; a second speed sensor associated with the ground engaging propulsion mechanism on the right side of the machine, said second speed sensor producing a right propulsion speed signal; an operator input producing an input signal; an electronic controller receiving said left propulsion speed signal and said right propulsion speed signal and said input signal and producing a control signal associated with said first motor and a control signal associated with said second motor to control said first and second motors as a function of said input signal, said left propulsion speed signal and said right propulsion speed signal.
