Steering system with joystick mounted controls
First Claim
1. A steering system for a machine, comprising:
- at least one hand-operated work implement control device;
a steering mechanism configured to control a direction of travel of the machine;
a first steering device operatively coupled to the steering mechanism and configured to control at least one component of the steering mechanism based on operator input; and
a second steering device mounted on the work implement control device, the second steering device being configured to be selectively operatively coupled to the steering mechanism to thereby control a direction of travel of the machine based on lateral movement of the second steering device relative to the work implement control device.

Abstract
A steering system is provided for a work machine. The steering system may include at least one hand-operated work implement control device and a steering mechanism configured to control a direction of travel of the work machine. The system may also include a first steering device operatively coupled to the steering mechanism and configured to control at least one component of the steering mechanism based on operator input. The system may further include a second steering device mounted on the work implement control device. The second steering device may be configured to be selectively operatively coupled to the steering mechanism to thereby control a direction of travel of the work machine based on lateral movement of the second steering device relative to the work implement control device.

32. A method of steering a machine, comprising;
-
operating a steering device operatively coupled to a steering mechanism to control a direction of travel of the machine; activating a secondary steering system by selectively operatively coupling a multifunction input device to the steering mechanism, the multifunction input device being mounted on a hand-operated work implement control device configured to control movement of a work implement; operating the multifunction input device in a first mode of operation to control a direction of travel of the machine; selectively operatively coupling the multifunction input device to at least one component of a system configured to perform an alternative of the machine; and operating the multifunction input device in a second mode of operation to control the alternative function of the work machine. - View Dependent Claims (33, 34, 35, 36, 37)
