Patent 6921109 was granted and assigned to DEERE & COMPANY on July, 2005 by the United States Patent and Trademark Office.
The present invention relates to a steering linkage device which transmits a user's input motion to at least one wheel of a vehicle, wherein the steering linkage device produces an output motion of a particular magnitude. The ratio of the magnitude of the input motion to the magnitude of the output motion varies, depending upon the magnitude of the input motion. The steering linkage device enhances the steering control of vehicle users by varying the steering responsiveness for different steering motions made by the users.
