The tractor is one of the most important agricultural and farming machines, featuring a unique and unusual design. But why is the tractor designed this way, with the front wheels being much smaller than the rear wheels? And why is water added to the rear wheels? What role does water play in the tires?


Why Are the Front Wheels of a Tractor Smaller Than the Rear Wheels:

As a general rule, the front wheels of a tractor act as a base and do not carry significant weight or pressure. They are primarily responsible for steering and changing the tractor’s direction. In contrast, the rear wheels are designed to penetrate muddy terrain and rough landscapes, providing greater contact with the ground, which ensures better stability and control.

Why Is Water Added to the Rear Wheels of a Tractor:

As mentioned earlier, the rear wheels are responsible for controlling the tractor and bearing a significant amount of weight. To enhance the tractor's stability, water is added to the rear wheels to shift more weight toward the back, improving balance and traction.

When the rear wheels of a tractor are filled with water, the overall weight of the tractor increases, but this also enhances its traction power and improves its ability to float on waterlogged terrain.


The water inside the rear wheels shifts the tractor’s center of gravity downward, which significantly improves stability and prevents tipping over. Additionally, it makes it easier to attach heavy rear-mounted equipment, such as harvesting tools or large plows. Therefore, the added weight in the rear wheels helps keep the tractor stable and prevents slipping.
