The intake duct may generally include a body defining an air passage extending between an intake end and an outlet end. The body may further define a recessed intake at the intake end including a first side section and a second side section. Each of the first side section and the second side may define at least one side opening for directing air into the air passage. In addition, the recessed intake may include a deflector projecting outwardly from the first and second side sections. The deflector may be configured to shield the air passage from water directed towards the recessed inlet. ## Claims ### Claim 1 An intake duct for an air intake system of a work vehicle, the intake duct comprising: a body defining an air passage extending between an intake end and an outlet end, the body further defining a recessed intake at the intake end including a first side section and a second side section, at least one of the first side section or the second side defining an opening for directing air into the air passage, the recessed intake further including a deflector projecting outwardly from the first and second side sections, the deflector being configured to shield the air passage from water directed towards the recessed inlet. ### Claim 2 (depends on 1) The intake duct of claim 1, wherein the deflector is configured to project outwardly from the first and second side sections so as to define an at least partially curved shape between the first and second side sections. ### Claim 3 (depends on 1) The intake duct of claim 1, further comprising a screen covering the recessed intake, the deflector projecting outwardly from the first and second side sections in the direction of the screen. ### Claim 4 (depends on 3) The intake duct of claim 3, wherein the recessed intake defines an outer edge, the screen being coupled to the body around the outer edge. ### Claim 5 (depends on 1) The intake duct of claim 1, wherein the deflector includes a first deflector portion extending between a top edge and a bottom edge and a second deflector portion extending between a top edge and a bottom edge, the first deflector portion being flared outwardly at its bottom edge relative to the top edge of the second deflector portion such that a first deflector opening is defined between the first and second deflector portions. ### Claim 6 (depends on 5) The intake duct of claim 5, wherein the bottom edge of the first deflector portion is horizontally aligned with or disposed vertically below the top edge of the second deflector portion. ### Claim 7 (depends on 5) The intake duct of claim 5, wherein the bottom edge of the first deflector section defines a non-rounded shape. ### Claim 8 (depends on 5) The intake duct of claim 5, wherein the deflector further includes a third deflector portion extending between a top edge and a bottom edge, the second deflector portion being flared outwardly at its bottom edge relative to the top edge of the third deflector portion such that a second deflector opening is defined between the second and third deflector portions. ### Claim 9 An air intake system for a work vehicle, the air intake system comprising: an intake duct defining an air passage extending between an intake end and an outlet end, the intake duct further defining a recessed intake at the intake end including a first side section and a second side section, at least one of the first side section or the second side defining an opening for directing air into the air passage, the recessed intake further including a deflector projecting outwardly from the first and second side sections, the deflector being configured to shield the air passage from water directed towards the recessed inlet; and a filter assembly in flow communication with the outlet end of the intake duct, the filter assembly being configured to filter the air received within the intake duct. ### Claim 10 (depends on 9) The air intake system of claim 9, wherein the deflector is configured to project outwardly from the first and second side sections so as to define an at least partially curved shape between the first and second side sections. ### Claim 11 (depends on 9) The air intake system of claim 9, further comprising a screen covering the recessed intake, the deflector projecting outwardly from the first and second side sections in the direction of the screen. ### Claim 12 (depends on 11) The air intake system of claim 11, wherein the recessed intake defines an outer edge, the screen being coupled to the body around the outer edge. ### Claim 13 (depends on 9) The air intake system of claim 9, wherein the deflector includes a first deflector portion extending between a top edge and a bottom edge and .a second deflector portion extending between a top edge and a bottom edge, the first deflector portion being flared outwardly at its bottom edge relative to the top edge of the second deflector portion such that a first deflector opening is defined between the first and second deflector portions. ### Claim 14 (depends on 13) The air intake system of claim 13, wherein the bottom edge of the first deflector portion is horizontally aligned with or disposed vertically below the top edge of the second deflector portion. ### Claim 15 (depends on 13) The air intake system of claim 13, wherein the bottom edge of the first deflector section defines a non-rounded shape. ### Claim 16 (depends on 13) The air intake system of claim 13, wherein the deflector further includes a third deflector portion extending between a top edge and a bottom edge, the second deflector portion being flared outwardly at its bottom edge relative to the top edge of the third deflector portion such that a second deflector opening is defined between the second and third deflector portions.
