Why tractors have vertical exhaust?

Why tractors have vertical exhaust ?                            

Tractors are extremely important agricultural vehicles. These machines are ubiquitous across the globe and range from rather small lawn tractors to giant monster worth hundreds of thousands of dollars. However, most of them have something in common – their exhaust pipes are pointing straight up in front of the driver’s cab. Meanwhile exhaust pipes of cars are located at the back, typically at bottom of the vehicle. Why is that? We will discuss the reason behind the vertical exhaust in this article.


Following are the reason why tractors have vertical exhaust :

1) Tractor is a off-road vehicle, usually used in every terrain including water dominated areas, where, there are chances of water to get in exhaust pipe and causing harm to the engine and exhaust system itself.

2) Mounting the exhaust pipe in the front has an added cost advantage – that’s where the engine is and less pipework is required this way. Less pipework – less maintenance as well.

3) Many chemicals are spread on crops or plants by driving tractor on the space between plants. If exhaust system is horizontal and below the driver them harmful and hot emissions can harm the crop.

4.) A normal tractor is constituted of two major parts – it can be split in two, which is occasionally done to repair transmission. Having an exhaust running from front to back would make such repairs hardly possible or very difficult.

Special note - Sometimes the end of exhaust pipe is curved, or has a hinged cover flap which the gas flow blows out of the way, to try to prevent foreign objects (including droppings from a bird perching, rain drops, ice on the exhaust pipe when the vehicle is not being used) getting inside the exhaust pipe.
