Abstract:
1. A method of operating a work machine, the work machine being operable in a manual-control mode and an auto-control mode, the manual-control mode for controlling performance of a hydraulic function as a function of the position of an operator input device, the auto-control mode for automatically controlling performance of the hydraulic function in a predetermined manner independent of the position of the operator input device, the method comprising: activating the auto-control mode in response to displacement of the operator input device to an activate-auto position relative to a neutral position of the operator input device, both deactivating the auto-control mode and activating the manual-control mode in response to displacement of the operator input device from the neutral position through a non-responsive deadband about the neutral position to an activate-manual position, and changing the size of the deadband either upon activating the auto-control mode in response to displacement of the operator input device to the activate-auto position or upon both deactivating the auto-control mode and activating the manual-control mode in response to displacement of the operator input device from the neutral position through the deadband to the activate-manual position, wherein the changing comprises enlarging the deadband upon activating the auto-control mode in response to displacement of the operator input device to the activate-auto position.
