Tractors, which came as a revolution in the field of agriculture, greatly facilitated people’s work. With its very powerful engines, it can easily perform extremely demanding tasks. tractorsclears the way for us to process much larger countries with less manpower. Have you ever thought about why tractor design is like this? Why are the front wheels on these machines so small when the rear wheels are so much bigger?

Today we will tell you why tractors, which are indispensable in agriculture, front wheels with large rear wheels We will explain that it is smaller. At this point, many issues, from cost to technical issues, come into play.

First let’s understand how the tractor works.

Tractors generally have 4×2 traction. There is power in 2 wheels instead of power in 4 wheels. This power is transferred to the large rear wheels. good We can say that tractors are rear-wheel drive vehicles. Since their areas of use are muddy, rough terrains, they must have powerful engines.

Why do tractors have big wheels on the back?

diesel engine Tractors that drive it have large wheels at the rear, so they can drive over rough terrain without any problems. behind the tractors tires with large and large surface areaensures the vehicle’s traction even on the most difficult surfaces. For example, if a normal car enters a field with soft ground, the wheels will likely sink into the ground and the vehicle will get stuck in the ground.

Tires at the rear of the tractors, which have both a large diameter and a large surface area, prevent the tractor from getting stuck on the ground. However, tractor tires Too wide teeth Even if the ground he moves on is soft, it helps him move without slipping.

If these big tires are so affordable, why are there small wheels in the front?

While big wheels are very good at obstacles, they are not very successful when it comes to agility. With smaller wheels in the front make the tractor much more manoeuvrableThis allows you to make sharp turns. The large wheel also causes vision problems. Small wheels in the front allow the driver to see a much larger area. Finally, small tires are more economical than large tires.

While it is beneficial to have large tires, you do not need large tires up front. The small tires in the front prevent an extra cost. revealed agility When factors like these are added up, it is more than enough that only the rear wheels are large.

Different wheel sizes also distribute the weight distribution correctly.

You know the tractor engine is in the front. This means that the weight is spread forward. The task of balancing this lies with the rear wheels. Extreme heavy rear wheelsprevents the weight from coming forward on its own. In addition, the larger diameter of the rear wheel means that the axle is higher. This makes the tractor act as a lever. Because the tractor is like this, the maximum pulling force is even greater before the vehicle rolls over. In other words, the rear wheels allow the vehicle to both make the pulling power safely and distribute the weight of the tractor in general.

Large wheels also protect the bottom.

The natural environment of tractors is fields. Tractors that prepare the soil before planting the seeds because they are very heavy. can also compact the soil. The large surface area of ​​the rear tires also comes into play at this point. Due to this width, the weight is distributed over the ground and the tires do not press the ground too much. Considering that it will be very difficult for plants to grow in compacted soils, we can say that these wheels perform another extremely important action.

Today we explained to you why the rear wheels are bigger than the front wheels on tractors. If you want more of this kind of content, don’t forget to share it with us in the comments section.
