A cooling system includes a first cooler, a second cooler, a fan positioned to drive air through the first cooler and the second cooler, and a baffle system. The baffle system includes a baffle and an actuator. The baffle is positioned to facilitate selectively restricting airflow through at least a portion of the first cooler. The actuator is positioned to facilitate reconfiguring the baffle between (i) a first orientation where the baffle does not restrict the airflow through the portion of the first cooler and (ii) a second orientation where the baffle restricts the airflow through the portion of the first cooler, thereby diverting additional airflow through the second cooler.

A fluid tank that includes a housing. The housing includes a bottom wall, a top wall, and a side wall. The side wall couples the bottom wall to the top wall to define a cavity that receives and houses a liquid. A conduit guides liquid from a fluid source into the cavity. The conduit defines an inlet and an outlet. The outlet couples to the side wall. A vent coupled to the housing and to the conduit. The vent defines a vent inlet coupled to the housing and a vent outlet coupled to the conduit. The vent discharges gas from the housing into the conduit.

An operator cab for a work vehicle includes: a cab enclosure including a roof an operator chair disposed in the cab enclosure; at least one layer of noise-deadening material coupled to the roof; and a headliner coupled to the roof such that the at least one layer of noise-deadening material is at least partially disposed between the headliner and the roof. The headliner includes a noise-reflective material and a noise escape region that comprises at least one opening configured to allow sound waves to pass through the noise escape region into the at least one layer of noise-deadening material and reduce noise reflection by the headliner to the operator chair.

A selective catalytic reduction (SCR) system includes a SCR canister including a SCR inlet configured for receiving engine exhaust from a work vehicle and a SCR outlet configured for expelling a treated exhaust flow. The system includes first and second SCR chambers housed within the SCR canister and configured to react mixtures of exhaust reductant and associated first and second portions of the engine exhaust with a catalyst to generate first and second treated exhaust flow portions, respectively. The system includes an outlet chamber positioned between the SCR outlet and the first and second SCR chambers. Moreover, the outlet chamber is configured to combine the first and second treated exhaust flow portions to form the treated exhaust flow. Further, the system includes a chamber mixer positioned upstream of the SCR outlet and configured to promote mixing of the first and second treated exhaust flow portions within the outlet chamber.

An exhaust system for a work vehicle includes a selective catalytic reduction (SCR) assembly that includes an SCR module. The SCR module includes a first exhaust flow path and a second exhaust flow path. The SCR assembly also includes an inlet configured to receive a flow of an exhaust solution, to direct a first portion of the exhaust solution to the first exhaust flow path, and to direct a second portion of the exhaust solution to the second exhaust flow path. The SCR assembly further includes an outlet mixer configured to receive the first and second portions of the exhaust solution and to direct the first and second portion of the exhaust solution out of the SCR assembly. The outlet mixer includes one or more features configured to mix the first and second portions of the exhaust solution.

An air intake system for an off-road vehicle includes an intake conduit upstream of a segmented debris removal device and a mail filter element. A baffle is disposed in the intake conduit and extends into the incoming air stream to avoid swirl in the air stream and provide more even air flow distribution into the segments of the segmented debris removal device. The baffle may have two generally parallel elements spaced from one another to reduce mixing of air regions separated by the baffle. The baffle reduces or eliminates vortices that adversely affect air flow into the segmented debris removal device.
