A vehicle includes a frame, at least one traction device coupled to the frame for facilitating movement of the vehicle, an implement coupled to the frame and configured to perform a work operation, a gearbox, a hydraulic system having a hydraulic reservoir, and an oil cooling system configured to cool the gearbox and the hydraulic system. The oil cooling system includes first and second circuits for a cooling oil, and a crossover circuit. The first circuit includes the gearbox and a first oil-to-air cooler configured to cool the cooling oil from the gearbox. The second circuit includes the hydraulic reservoir and a second oil-to-air cooler for cooling the cooling oil from the hydraulic reservoir. The crossover circuit includes the gearbox and the hydraulic reservoir and is configured to exchange the cooling oil between the gearbox and the hydraulic reservoir to provide heat transfer between the first and second circuits.

A system for sensing the angular position of a caster wheel includes a sensor mounted on a bearing which supports a shaft aligned with the rotational axis of the caster. A target on the shaft is detected by the sensor which generates signals indicative of the presence or absence of the target. The position of the target is coordinated with the position of the caster wheel such that the signals are indicative of the angular position of the caster wheel. The target may be a groove extending partially around the shaft and a remaining ungrooved portion of the shaft.

A forestry machine includes a ground propulsion apparatus, a chassis supported by the ground propulsion apparatus, a cab, an engine and a work implement. The chassis includes a front chassis portion and a rear chassis portion. The front chassis portion includes an upper portion and a lower portion. The rear chassis portion has a wood basket supported thereon. The cab is rotatably supported on the front chassis portion by a rotatable connection about a cab rotation axis to be selectively rotated 360 degrees. The engine is integrated into the front chassis portion. At least a part of the engine is disposed below an upper most surface of the upper portion. The work implement is movably attached to the cab. The work implement includes a boom movably attached to the cab, an arm movably attached to the boom, and a work tool attached to the arm.

A dual-clutch transmission includes an odd gears clutch, an odd gears shaft supporting at least two odd-numbered rotary gears, an even gears clutch, and an even gears shaft supporting at least two even-numbered rotary gears. A driven rotary shaft is selectively connectable to one respective said odd- or even-numbered gear at a time. The dual-clutch transmission includes first and second range selection gears to transfer drive from the driven rotary shaft to an output shaft so as selectively to permit selection of at least a first range transmission ratio or a second range transmission ratio. The dual-clutch transmission further includes a first bypass drive line to drive engagement of at least two mutually engaged bypass rotary gears with the output shaft, giving rise to a first intermediate transmission ratio.

Cooling and debris mitigation systems for use with work vehicle powertrains include a pressurized air source, a plurality of impingement outlets positioned proximate the work vehicle powertrain, and a flow network fluidly coupling the pressurized air source to the impingement outlets. A first vortex tube is positioned in the flow network and configured to separate pressurized airflow received from the pressurized air source into a hot stream and a reduced temperature stream. The first vortex tube includes a vortex tube inlet fluidly coupled to the pressurized air source, an exhaust port through which the hot stream is discharged, and a nozzle through which the reduced temperature stream is discharged. The reduced temperature stream impinges upon at least one of the targeted exterior regions of the work vehicle powertrain to provide cooling thereto and reduce debris accumulation thereon.

The present disclosure includes a travel operation unit that is configured to be manually operated and includes a mode operation tool for switching between automatic driving and manual driving, a manual travel control unit that includes a manual travel mode in which manual driving is performed based an operation signal received from the travel operation unit, and an automatic travel control unit that includes an automatic travel mode in which automatic driving is performed, a temporary stop mode in which a vehicle body is temporarily stopped during automatic driving for transitioning from the automatic travel mode to the manual travel mode, and a check mode in which whether a state of the travel operation unit satisfies a manual driving transition condition required for starting manual driving is checked in transition from the temporary stop mode to the manual travel mode.

A combine harvester tailings return system includes a tailings conveyor and an ejection channel for depositing tailings upstream of a cleaning system. A proximity sensor is mounted to the ejection channel and is configured to sense the height of a layer of tailings during transit through the returns system.

A cooling system may include a skeleton frame having a central opening to receive and frame at least one cooling core. The skeleton frame has an interior to contain at least one conduit through which at least one fluid to be cooled may flow to the at least one cooling core. The cooling system may further include a skin wrapping over and about the skeleton frame to seal the interior of the skeleton frame.

A work vehicle including a body, a cooling system with one or more coolers, and a fan disposed adjacent to the coolers. A louver system is disposed adjacently to an inlet of the vehicle body. The louver system includes a first actuator operatively connected to a first plurality of slats and a second actuator operatively connected to a second plurality of slats. A first sensor operatively connected to a first cooler is configured to identify a first temperature of the first cooler and to generate a signal responsive to the identified first temperature. A second sensor operatively connected to a second cooler is configured to identify a second temperature of the second cooler and to generate a signal responsive to the identified second temperature. A position of the first plurality and second plurality of slats is determined respectively by the first and second temperatures.

An air management assembly for a work machine, the air management assembly having a cooling orifice defined in a panel, a cooling fan generating a cooling airflow through the cooling orifice to a cooling package, at least one fixed screen positioned along an intake orifice, and a first baffle positioned at least partially between the cooling orifice and the intake orifice. Wherein, the first baffle directs the cooling airflow partially across the fixed screen to clear the fixed screen of debris.
