Abstract: An autonomous driver system for an agricultural vehicle assembly includes a sensor interface configured for coupling with one or more of vehicle sensors or implement sensors and a function interface configured for coupling with one or more of vehicle actuators or implement actuators. An autonomous driving controller is in communication with the sensor and function interfaces. The autonomous driving controller is configured to autonomously implement a planned agricultural operation with the agricultural vehicle and the agricultural implement. The controller is configured to identify and remedy one or more operation disturbances outside of the planned agricultural operation including identifying the one or more operation disturbances with one or more of the vehicle or implement sensors and selecting one or more remedial actions for the one or more operation disturbances. The controller is configured to implement the one or more remedial actions with one or more of the vehicle or implement actuators.

Abstract: A heat exchanger has first and second sides and comprises a pair of tanks, with each of the tanks defining an interior and including a header. A plurality of openings is formed in the header; The heat exchanger comprises a plurality of tubes extending between the openings in the tanks, with each of the tubes having opposite end portions joined to the tanks to fluidly connect the interiors of the tanks through interiors of the tubes. The heat exchanger comprises at least one reinforcement ribbon element extending across a juncture between the header and the plurality of tubes to reinforce a connection between the header and the plurality of tubes.

Abstract: An agricultural windrower includes a vehicle chassis, a lift frame movably mounted to the vehicle chassis, and a crop harvesting header coupled with the lift frame. The header includes a main frame and an integrated header float system. The header float system has at least one float cylinder coupled with the main frame. The header also includes a suspension which may be selectively mounted to one of a plurality of differently configured types of agricultural harvesters, such as a combine or windrower.

Abstract: In an agricultural combine, a header float system using a floating header having a frame, a support member supporting the frame from the ground, and a suspension variably supporting the frame from the combine. The suspension comprises a sub-frame removable attaching to the combine, links movably attaching the frame and the sub-frame, and one or more float cylinders moveably supporting the frame from the sub-frame. A float circuit connects to the float cylinder, and a float valve connects the float circuit to a main hydraulic circuit. A pressure sensor connects to the float circuit, and a controller communicates with the float valve and the pressure sensor. The controller maintains pressure in the float circuit at a target value by continuously reading the pressure sensor and commanding the float valve to add or subtract hydraulic fluid in the float circuit until pressure equals the target value.
