  • Manual motion control override apparatus
    Patent number: 5205181
    Abstract: An override control system for a ground-supported machine. A hand lever is used to adjust the equilibrium position of a self-centering device which is interconnected to a drive system of the machine so that a principal ground speed of the machine is selected and set by adjustment of the hand lever. A second control lever is connected to the drive system through the self-centering device and is operable to adjust the speed and direction of motion of the machine away from that set by the hand lever. Upon release of the second control lever, the self-centering device returns the ground speed of the machine to the preselected principal value.
