Abstract

A track-type machine includes first and second ground-engaging track assemblies, each having a drive motor, and a propulsion system including an operator station with first and second joysticks, and a travel control system including input devices resident on the first and second joysticks. The input devices are adjustable to vary at least one of a speed or a direction of the drive motors in the track assemblies. Adjustment of the drive motor speed can be in proportion to an adjustment of the corresponding input device.
