Patent number: 8678113Abstract: A dual-path hydrostatic drive arrangement for driving ground wheels at the opposite sides of the front of a self-propelled windrower is controlled for effecting steering and ground speed changes by a control mechanism including a gear train defined by a steering input gear and idler gear and steering output gears carried by a gear support member mounted for pivoting about a fixed axis of rotation of the input gear. The output gear is coupled for transmitting movement to first and second pump displacement control rods and steering is effected by turning a steering wheel which is coupled for rotating the input gear so as to impart rotation to the output gear which rotates so as to cause the control rods to move different amounts or in different directions. Speed changes are effected by a speed control device that is coupled for selectively swinging the speed/direction control arm.Type: GrantFiled: April 25, 2011Date of Patent: March 25, 2014Assignee: Deere & CompanyInventor: Thomas Daryl Bebernes

Patent number: 8496256Abstract: A work machine includes a frame, at least one drive wheel carried by the frame, at least one caster wheel assembly carried by the frame, and at least one turn assist arrangement. Each turn assist arrangement is coupled between the frame and a corresponding caster wheel assembly.

Patent number: 8087225Abstract: An agricultural windrower includes a traction unit having a frame. A cutting platform has a longitudinal extension, a feeder opening associated with a first mounting location, and a first hitch at an end of the cutting platform associated with a second mounting location. A lift assembly carried by the traction unit frame is configured to mount with the cutting platform at the first mounting location. An articulated transport arrangement is mounted to the traction unit frame. The articulated transport arrangement includes a second hitch configured for mating with the first hitch, and at least one actuator for coupling between and adjusting a relative angular orientation between the frame and the cutting platform when the first hitch and the second hitch are mated together.Type: GrantFiled: February 11, 2008Date of Patent: January 3, 2012Assignee: Deere & CompanyInventors: Gordon Lee Salley, Thomas Daryl Bebernes

Patent number: 7789408Abstract: A suspension arrangement for a work machine includes a frame and a rear axle rigidly carried by and substantially immovable relative to the frame. The suspension arrangement includes a caster wheel assembly having a shaft, a wheel arm, a suspension and a caster wheel. The shaft is pivotably couplable with an outboard end of the rear axle. The caster wheel is coupled with a lower end of the wheel arm. The suspension is in the form of a torsion spring including an outer tube, an inner member, and a plurality of elastomeric members interposed between the outer tube and the inner member. The outer tube is coupled with the shaft, and the inner member is coupled with an upper end of the wheel arm.Type: GrantFiled: January 3, 2008Date of Patent: September 7, 2010Assignee: Deere & CompanyInventors: Charles Scott Sloan, Allan Wesley Rosenbalm, Thomas Daryl Bebernes

Patent number: 6523635Abstract: A vehicle has a pair of opposite drive wheels driven by a dual path hydrostatic transmission. Steering and speed/direction controls are effected by changing the displacement and/or direction of fluid flow through the pair of reversible, variable displacement pumps that are respectively coupled to fixed displacement ground wheel drive motors. The control mechanism for accomplishing steering and/or speed/direction control includes a steering rack that is caused to pivot about a fixed post in response to steering wheel movement. A first crank arm is coupled for pivoting in concert with the rack and a second crank arm is coupled for pivoting in concert with a pivot plate about a second axis, the pivot plate having a pair of connection points respectively coupled to control arms of the pair of pumps by a pair of pump control rods. The pivotal motion of the steering rack is transmitted to the pivot plate by a tie-rod coupled between the first and second crank arms.Type: GrantFiled: November 2, 1999Date of Patent: February 25, 2003Assignee: Deere & CompanyInventors: Robert James Johnston, Thomas Daryl Bebernes

Patent number: 5778644Abstract: A self-propelled windrower is provided with a platform including a reel which sweeps crop to be cut over a sickle cutterbar and into the nip of a pair of counter-rotating center-feed augers that, in turn, deliver the crop to the nip of a pair of counter-rotating conditioner rolls; and these driven components may be reversed to disgorge slugs of crop. The reversible drive includes a hydraulic pump carried by the traction unit and coupled to a motor carried by the platform. The hydraulic motor on the platform is coupled to power a main gear box which distributes power to the driven components of the platform. Operation of the pump is electro-hydraulically controlled with a single switch being operable to effect forward operation of the platform drive train, and with a second switch being designed to be moved and held in place to effect and maintain the drive train in reverse.Type: GrantFiled: August 9, 1996Date of Patent: July 14, 1998Assignee: Deere & CompanyInventors: Melvin William Keller, David Henry Diebold, Steven Lawrence Schmid, Stanley Paul Wellman, Frederick Carl Krambeck, Thomas Daryl Bebernes

Patent number: 5649606Abstract: A steering and ground speed control mechanism of a vehicle equipped with a dual-path hydrostatic drive system includes a pivot plate fixed to a vertical pivot post at a location between and equidistant from a pair of locations respectively linked to a pair of pump displacement control arms of a pair of pumps respectively coupled for delivering fluid to right- and left-hand drive motors coupled to right- and left-hand ground wheels. A train of elements for transferring steering inputs from a steering wheel to the pivot plate includes a timed belt and sprocket set with one of the sprockets being fixed to the pivot post and the other mounted to a fixed post together with a quadrant-shaped steering rack for pivotal movement about the fixed post in concert with the rack. Pivoting the pivot plate in opposite directions from a centered position causes different displacements of the pumps and, hence, in the two drive motors being driven at different speeds.Type: GrantFiled: May 26, 1995Date of Patent: July 22, 1997Assignee: Deere & CompanyInventors: Thomas Daryl Bebernes, Robert James Johnston
