why tractor have big rear wheel

Tractors are one of the most versatile and effective agricultural vehicles that we have today. These machines are used for various tasks, such as plowing fields, planting crops, hauling loads, and much more. One of the most striking features of tractors is their large and sturdy rear wheels. Have you ever wondered why tractor wheels are so big? In this article, we will explore the reasons behind this design and how it benefits the tractor's performance and functionality.

Functionality and Traction

The most obvious reason for tractor wheels to be big is to provide better traction. Tractors are often used on uneven and challenging terrain, and the large wheels are designed to ensure that they can grip the ground and provide sufficient power when pulling or pushing. Bigger wheels provide a larger surface area for the tires to make contact with the ground, reducing the risk of the machine getting stuck in mud or soft terrain. It also enables the tractor to handle heavy loads better, with a better grip on the surface.

Stability and Strength

Tractors are expected to perform consistently throughout their lifetime, and their strength and stability are crucial factors. The large rear wheel design provides stability and strength to support the weight of the machine. The extra weight of the wheel acts as a counterbalance to the heavy front end, ensuring that the tractor does not tip over. Stability helps in maintaining the machine's direction of movement, preventing any sways that might endanger the driver or any other occupants.

Ground Clearance and Fuel Efficiency

Another benefit of the large tractor wheels is the increased ground clearance. The wheelset's height provides sufficient clearance from any obstacles on the ground, reducing chances of getting stuck or damaging undercarriage parts. A higher level of clearance also allows the farmer to work with tall crops without damaging the plants. Additionally, the oversized wheel design promotes fuel efficiency, reducing the amount of power needed to move the tractor because of reduced friction.

Conclusion

In conclusion, the larger-than-life tractor rear wheel design serves various purposes that support their application in the farming industry. The wheels' diameter offers tractions on challenging terrains while providing stability, strength and facilitating fuel efficiency. While technology is continuously improving farm machinery, this essential and effective design aspect remains relevant and reliable. The next time you see a tractor with immense wheels rolling through a field, you will know why they are the way they are.
