| A forage harvester including a header for picking up a swath from a ground surface. The header includes a first and a second distance sensor adapted to measure a sensor-to-target distance respectively along a first and second sensor axis. The first distance sensor is mounted at a first lateral end of the header, and the second distance sensor is mounted at a second lateral end of the header. The first and second distance sensors are positioned such that, when the forage harvester is placed on an even ground surface, the first sensor axis crosses the second sensor axis before reaching the even ground surface in front of the harvester. | ||||||

| An agricultural implement has front flotation wheels with a significantly increased diameter, increasing flotation and improving rolling characteristics, especially in soft soil conditions. The implement has a frame supported on front and rear wheels. Front flotation wheels are pivotally mounted to the frame about vertical axes. A hitch tongue is pivotally attached to the frame about a vertical hitch pivot axis. A wheel control mechanism connects the front flotation wheels to the hitch tongue, and is configured such that when the hitch tongue is in a neutral position the front flotation wheels roll in the operating direction, and pivoting the hitch tongue causes the front flotation wheels to pivot in the same direction. | ||||||

| An agricultural vehicle has an implement connection hitch which is moveable relative to a rear axle of the vehicle. A system for controlling movement of the connection hitch is coupled with position sensors such as a GPS receiver. During turning maneuvers, the control system moves the hitch relative to the rear axle of the vehicle until it reaches an offset position such as to reduce the turning circle of the vehicle and a connected implement. The extent of offset may be determined automatically by the control system on identification of a connected implement. | ||||||

| A rotary mower has a center mower deck and a hitch arm assembly adapted at a front end for connection to a tractor drawbar. A hydraulic pump is mounted on the hitch arm assembly and connected to a hydraulic motor mounted on the center mower. An upward arm section of the hitch arm assembly extends upward from a front portion of the hitch arm assembly to provide a desired clearance distance between a middle arm section of the hitch arm assembly and the ground, and a downward arm section of the hitch arm assembly extends downward from the middle arm section to a rear end of the hitch arm assembly which is pivotally connected to the mower deck about a hitch pivot axis oriented horizontally and perpendicular to the operating travel direction. The hitch pivot axis is located at a vertical position below top edges of the front wheels. | ||||||

| An agricultural tillage implement has a steerable rear axle which facilitates the implement more faithfully following a towing unit. The implement has a solid axle mounted to the main pull frame that allows for vertical movement of the implement to switch between field operation and a transport configuration. Attached to the solid axle are two steering knuckles that are tied together by an adjustable tie rod and two hydraulic steering cylinders. On each knuckle is a set of walking tandems to which the tires are mounted. The two cylinders are connected to an auxiliary port in a towing traction unit to enable the steering function without having to turn the unit steering wheel. The arrangement allows the steering knuckles to turn up to 25 degrees in either direction. | ||||||

| A steering system for a towable implement includes a steering sensor, an implement steering controller, a steering control valve, a steering cylinder, and an implement steering mechanism that steers the implement. The steering sensor measures, directly or indirectly, the angular position of the steerable wheels of the implement. The implement steering controller processes feedback from the steering sensor and with a desired steering angle, outputs a steering control signal that is input to the steering control valve. The steering control valve controls the flow of hydraulic fluid to the steering cylinder, which, in turn, powers the implement steering mechanism to turn the wheels of the implement. The steering system may be operated in various control modes, such as, a transportation steering mode, a corner and 180 turn steering mode, a swath tracking steering mode, crab steering mode, and a manual steering mode, which allows manual control of the steering system. | ||||||
