Abstract
A motion control system for controlling the motion of a crawler having a left and right track. The system comprises a pivotally mounted controller; a steering control system hydraulically communicable with a pressurized fluid supply, a brake of each of a left and right track of a crawler and a clutch of each of a left and right track of a crawler, a direction control system hydraulically communicable with a pressurized fluid supply, a forward and a reverse transmission signal input, a steering speed controlling system for controlling the speed of a left track and a right track, and a transmission gear controlling system. The steering speed controlling system includes at least one selector. The transmission gear controlling system includes at least one transmission gear selector. The steering control system is positioned so that pivoting the controller in a first series of planes operates the steering control system. Similarly, pivoting the controller in a second series of planes operates the direction control system. Furthermore, the at least one selector and the at least one transmission gear selector are associated with the controller.
