Patent number: 6921109Abstract: 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.Type: GrantFiled: August 29, 2002Date of Patent: July 26, 2005Assignee: Deere & CompanyInventors: Wayne Robert Hutchison, David Lewis Marchese

Patent number: 6484827Abstract: A vehicle such as a front engine tractor is adapted to utilize conventional steering and propel controls with a drive and steer type transmission. The transmission permits the vehicle to be driven and steered through its rear wheels, thereby permitting it to turn about one wheel and/or about an axis between its wheels. A substantial portion of the engine weight is carried on the vehicle frame forwardly of the transmission. Front castered wheels enable the vehicle to be easily steered by the drive wheels. A conventional type steering wheel is provided with a mechanical linkage extending between it and the transmission. Conventional type controls are also provided to propel or power the vehicle in a forward or rearward direction and within a range of speeds.Type: GrantFiled: January 25, 2001Date of Patent: November 26, 2002Assignee: Deere & CompanyInventors: Richard Donald Teal, Eugene Gary Hayes, David Lewis Marchese, Barry Joseph Goebert

Patent number: 6354388Abstract: A vehicle such as a lawn and garden tractor is adapted to utilize conventional steering and propel controls with a drive and steer type transmission. The transmission permits the vehicle to be driven and steered through its rear drive wheels, thereby permitting it to turn about one wheel and/or about an axis between its wheels. Front castered wheels enable the vehicle to easily steered by the drive wheels. A conventional type steering wheel is provided with a mechanical linkage extending between it and the transmission. Conventional type controls are also provided to propel or power the vehicle in a forward or rearward direction and within a range of speeds. With conventional type steering and propel controls adapted to be utilized with the drive and steer type transmission, operation of spin-turn vehicles is made simple and more efficient as well as reducing the time required to learn to operate and maneuver the vehicle.Type: GrantFiled: March 26, 1999Date of Patent: March 12, 2002Assignee: Deere & CompanyInventors: Richard Donald Teal, Eugene Gary Hayes, David Lewis Marchese, Barry Joseph Goebert

Patent number: 6196342Abstract: A steering mechanism that controls a drive and steer transmission and that causes the transmission to execute turns in the direction a steering wheel is turned when operating in either the forward or reverse direction of travel. In response to operator engagement of a drive control, an actuation linkage shifts an elongate member within a slot formed in a cam member that pivots in response to turning of a steering wheel. Shifting of the rod member between two positions on either side of the cam member pivot axis causes the drive and steer transmission to steer the vehicle in the desired direction when the vehicle is traveling in both forward and reverse.Type: GrantFiled: October 5, 1999Date of Patent: March 6, 2001Assignee: Deere & CompanyInventors: Richard Donald Teal, Eugene Gary Hayes, David Lewis Marchese, Barry Joseph Goebert, Wayne Robert Hutchinson
