摘要： One or more techniques and/or systems are disclosed for a hydraulic system that is used with a vehicle hitch, to raise and lower an implement attached to the hitch. The system has a lifting side, that raises the hitch, and a downforce side that applies downward pressure. Hydraulic actuators are used to apply the up or down force using supply lines coupled to both sides. A downforce pressure control valve controls an amount of hydraulic pressure is supplied to the downforce side. A mode select valve is fluidly coupled to the downforce pressure control valve and is used to select hitch operation between a double acting hitch position, a single acting hitch position, and a neutral position. A work port check valve is between the downforce side and the mode select valve to stop the fluid from flowing back into the system when de-energized or in the neutral position.

摘要： A sensor assembly for detecting the height of a mixture on a conveyor floor and/or a sieve of a cleaning system of a combine harvester is assembled with the combine harvester. The sensor assembly includes at least two light-sensitive sensors, positioned one above the other, and an emitter at a distance from the sensors, are attached on the upper side of the conveyor floor and/or the sieve. The sensors are configured to receive light radiated from the emitter as long as the light is not absorbed by the mixture, and the sensors are connected to an analysis device which is configured to generate an output signal representative of the height of the mixture on the basis of the output signal of the sensors.

摘要： One or more information maps are obtained by an agricultural work machine. The one or more information maps map one or more agricultural characteristic values at different geographic locations of a field. An in-situ sensor on the agricultural work machine senses an agricultural characteristic as the agricultural work machine moves through the field. A predictive map generator generates a predictive map that predicts a predictive agricultural characteristic at different locations in the field based on a relationship between the values in the one or more information maps and the agricultural characteristic sensed by the in-situ sensor. The predictive map can be output and used in automated machine control.

摘要： Systems and methods utilizing automation logic for powered ladders of work vehicles, including harvesters. A portion of the powered ladder can be displaced relative to other portions of the ladder so that the powered ladder is in either a folded or unfolded orientation. A controller can determine whether a secondary device, such as, for example, a header, is attached to the work vehicle. In response to at least determining the secondary device is not attached to the work vehicle, the folded powered ladder can be automatically displaced from an extended position to a retraced position. Upon detection of either or both a change in position of an operator, and a predetermined operational status of the work vehicle, the ladder can be displaced away from the retracted position, and the second portion of the powered ladder can be displaced so that the powered ladder can return to the unfolded orientation.

摘要： Methods and apparatuses are provided for deaeration of a liquid. Liquid may be impinged onto an inclined baffle and forced through a first plurality of apertures that direct the liquid in one or more directions away from one or more outlets of a reservoir. The liquid may be passed through a second plurality of apertures. Flowing the liquid as described promotes a circuitous route of travel and provides a residence time inside of the reservoir that promotes release of entrained air.

摘要： A row unit for a seeding machine includes a ground view sensor coupled to the frame. The ground view sensor is operable to sense the furrow and generate depth signals corresponding to actual sensed depth of the furrow. The row unit also includes a controller configured to receive the signals, and a downforce adjustment mechanism coupled to the frame and to the controller. The controller is configured to activate the downforce adjustment mechanism to adjust a downforce on the frame based on the signals received by the controller.

摘要： A dual core exhaust gas recirculation cooler includes a cooler housing having an EGR inlet, first and second EGR outlets, a cooling circuit extending from a coolant inlet through the cooler housing to a coolant outlet, a first EGR circuit core extending from the EGR inlet to the first EGR outlet, and a second EGR circuit core extending to the second EGR outlet from the EGR inlet or the first EGR outlet. A first EGR valve is configured to selectively couple the first EGR circuit core to a return passageway. A second EGR valve is configured to selectively couple the second EGR circuit core to the return passageway. The EGR valves are configured to selectively flow exhaust gas through the cooler housing within either the first EGR circuit core only or within both the first EGR circuit core and the second EGR circuit core.

摘要： A reel assembly for a harvester head of an agricultural machine includes a carrier bar, standard tines coupled to the carrier bar, and gap tines removably coupled to the carrier bar and such that the gap tines do not penetrate an outer surface of the carrier bar. The gap tines contact the standard tines to prevent rotation of the gap tines relative to the carrier bar during operation of the work machine.
