An off road vehicle has an air heater with right and left shells surrounding and supporting a core, with the right and left shells connected by screws extending through ears on one of the shells into bosses on the other shell. Dual air control plates are mounted in the shell on a shaft for pivoting movement. An actuator is linked to the shaft by a swing arm with a guide pin riding in an arced slot of a drive plate rotationally secured to the shaft. The right and left shells are secured to the vehicle using a resilient compressible grommet, with a bushing extending through the grommet and a bolt extending through the bushing and attached into the frame.

A vehicle includes a body mounted with a chassis, the body having a passenger compartment, a seat in the passenger compartment for supporting an occupant in a sitting position, and a roll over protection structure for the passenger compartment. The roll over protection structure includes an inlet coupled in gaseous communication to an air source, an outlet coupled in gaseous communication to a vehicle occupant wearable, and an airflow pathway through the roll over protection structure coupling the inlet to the outlet in gaseous communication.

A climate control system includes a plurality of vent registers, an HVAC unit delivering conditioned air to the plurality of vent registers, a side door status monitoring device and a controller configured to control opening and closing of the plurality of vent registers in response to side door status data provided by the side door status monitoring device. A related climate control method is also provided.

An earth working machine (10), having a propelling unit (22) and a machine frame (12) carried by the propelling unit (22), comprises a working apparatus (32) for earth working; an operator's platform (24), having an operating console (26) comprising a console body (52) and an operating panel (54, 66) that is movable relative to the console body (52) and has at least one operating element (58) associated or associatable with a functional device (32, 39) for control thereof. The operating panel (54, 66) is displaceable into a stowed position in which the at least one operating element (58) is covered by a portion (56a, 72a) of the console body (52.

An engine airflow adjustment system that includes an engine that powers operation of a vehicle. A fan drives an airflow over the engine to convectively cool the engine. A funnel receives a portion of the airflow from the fan and directs the airflow to a specific location on the engine to blow debris off of the engine.

An air conditioning system for an open motorized vehicle can include a cab assembly defining an interior volume, the cab assembly includes an enclosed frame configured to be attached to an open vehicle, and an air conditioning unit positioned at least partially within the cab assembly, the air conditioning unit being configured to deliver conditioned air to the interior volume of the cab assembly.

A vehicle misting device and method that is operable is dry and humid environments are provided. The device may also include a payment system and fan.

A riding vehicle is provided with a downdraft fan assembly mounted on a vehicle roll bar for providing a flow of ambient air over the vehicle operator and a canopy carried by the fan assembly and providing solar and precipitation protection for the operator.
