Disclosed is a complete engine cooling system for an engine carried by a grain harvesting combine having an internal combustion engine and hot exhaust components, and having a front operator cab. The system includes a generally horizontal fan assembly located atop the harvesting combine for drawing in air, a radiator associated with the engine and over which air flows for engine cooling, and charge air coolers for combustion air cooling, and air conditioning and hydraulic coolers, a centrifugal scroll that takes the drawn in air and removes entrained particles to produce a clean exhaust air and dirty exhaust air; and a filter assembly through which the pre-cleaned exhaust air flows for producing filtered air for admittance into the engine for combustion.

A plant shield assembly includes an elongated shield having a first door operably connected to a second door and both doors are pivotally connected to the vehicle and movable between an open position and a closed position. The plant shield assembly includes a door opening mechanism operably attached to the elongated shield and configured to move the first and the second doors. The plant shield assembly includes a linkage assembly that connects the elongated shield with the door opening mechanism, and limits the extent of rotation of the doors. The door opening mechanism and linkage assembly are positioned between the elongated shield and the vehicle. The door opening mechanism can be a handle attached to the elongated shield. Optionally, the plant shield assembly includes an access door that is disposed between an open position to enable actuation of the handle and a closed position to block actuation of the handle.

An airflow directional control system in an agricultural harvester having a grain tank or other structure, an internal combustion engine and a cooling system cooler box disposed between the grain tank or other structure and the internal combustion engine includes a cooler box cover over the cooler box between the grain tank or other structure and the internal combustion engine, at least one air director between the cooling box and the internal combustion engine and a panel adjustment system controlling tilt of side panels of the harvester.

A rotary dust screen for a cooling unit of an agricultural vehicle includes a frame having a ring shape, wherein a dust screen is mounted in the frame and wherein the frame includes a seal extending along the ring and comprising a lip adapted to abut, when the rotary dust screen is mounted on the cooling unit, against a housing of the cooling unit to prevent contaminants from entering the cooling unit at an edge of the dust screen, wherein the rotary dust screen further has a driving belt adapted to be driven by a rotary actuator to rotate the dust screen, wherein the driving belt engages with the rotary dust screen at an outer surface of the seal.

A cooler for a work vehicle includes at least one cooler core, a cooling fan associated with the at least one cooler core to produce a stream of air across the at least one cooler core, and a dust removal assembly including a filter associated with the at least one cooler core such that the stream of air passes through at least one collection surface of the filter. The dust removal assembly includes a suction channel placed such that it does not substantially interfere with the stream of air passing across the at least one cooler core, a blower fluidly coupled to the suction channel and configured to produce a suction region in and adjacent to the suction channel, and a filter carrier configured to carry at least a portion of the filter through the suction region such that particles captured by the filter are pulled into the suction channel.

A combine harvester includes a threshing device 4 configured to perform a threshing process of threshing reaped grain culm in a threshing chamber 23, in which the threshing chamber 23 includes a threshing cylinder 31 configured to rotate around a front-rear axis X, and an arc-shaped receiving net 32 provided extending along an outer circumferential portion of the threshing cylinder 31, and a top plate 30 covering an upper portion of the threshing chamber 23 is supported detachably along the rotation axis direction of the threshing cylinder 31.

A residue spread monitoring system for an agricultural harvester includes sensors and a controller configured to receive images from the sensors and determine a mode of plume evaluation as a first mode of plume evaluation or a second mode of plume evaluation; determine, in the first mode of plume evaluation, a first spread of the plume of residue based on the residue within the one or more first images; measure, in the second mode of plume evaluation, one or more first characteristics of dust represented in the one or more first images; and process, in the second mode of plume evaluation, the one or more first characteristics of dust is used to obtain the first spread of the plume of residue; and control operation of the agricultural harvester according to the first spread of the plume of residue.

The system includes a generally horizontal fan assembly located atop the harvesting combine for drawing in air, a radiator associated with the engine and over which air flows for engine cooling, and charge air coolers for combustion air cooling, and air conditioning and hydraulic coolers, a centrifugal scroll that takes the drawn in air and removes entrained particles to produce a clean exhaust air and dirty exhaust air; and a filter assembly through which the pre-cleaned exhaust air flows for producing filtered air for admittance into the engine for combustion.

A system for removing trash from a flow of harvested crop within an agricultural harvester may include a chopper assembly and a cleaning assembly downstream of the chopper assembly relative to the flow of harvested crop. An upstream side of the cleaning assembly may be positioned closer to the chopper assembly than a downstream side of the cleaning assembly. The cleaning assembly may include a screen and a fan, with the fan positioned at least partially between the upstream and downstream sides of the cleaning assembly. The fan may generate a flow of air in a first direction such that the flow of air passes through the upstream side before the downstream side of the cleaning assembly. Additionally, the screen may be movable along a travel path relative to the fan such that a portion of the screen is movable between the upstream and downstream sides of the cleaning assembly.
