Abstract

See full text

A control system for a machine equipped with a ripping tool. The control system includes a first operator input for generating a ripping control signal that initiates an auto-ripping mode. A second operator input is provided for generating a speed select signal for changing the transmission output speed of the machine to a selected transmission output speed. The system further includes a controller with a memory. The controller is linked to the first and second operator inputs. The controller is programmed to receive a ripping control signal from the first operator input and to activate the auto-ripping mode or auto-ripping mode and deactivate the auto-shift mode. The controller is also programmed to receive a speed select signal from the second operator input and to deactivate the auto-ripping mode and adjust the power source to the selected transmission output speed.
