TECHNICAL FIELD
[001] The embodiments herein relate to an exhaust device for an engine, which is configured to alter the direction of emission of exhaust gases from the engine in accordance to at least one of a first driving position and a second driving position.
BACKGROUND
[002] Vehicles such as tractors or other similar vehicles are primarily used in agricultural field operations. Exhaust system in a vehicle is used to emit the exhaust gases from an engine to the atmosphere in a controlled manner.

Providing an exhaust device for changing the direction of the emission of the exhaust gases of an engine in a vehicle having a plurality of driving positions is difficult and is one of the challenges posed to the original equipment manufacturers (OEM’s).
[003] Therefore, there exists a need for an exhaust device for an engine, 15 which obviates the aforementioned drawbacks.
OBJECTS
[004] The principal object of an embodiment of this invention is to provide an exhaust device for an engine, which is configured to alter the direction of emission of exhaust gases from the engine in accordance to at least one of a first 20 driving position and a second driving position.
[005] Another object of an embodiment of this invention is to provide an exhaust device, which is configured to be provided in an engine exhaust system of at least one of a vehicle and a machine.
[006] These and other objects of the embodiments herein will be better 25 appreciated and understood when considered in conjunction with the following description and the accompanying drawings. It should be understood, however, that the following descriptions, while indicating embodiments and numerous
