Tractors have been used for farming purposes since the early 20th century. They have significantly changed the way farming is done, and have become an indispensable part of modern agriculture. The design of tractors has evolved over time, and one noticeable feature is the size difference between the rear and front wheels. This article seeks to answer the question \"why do tractors have bigger rear wheels?\"
The Function of Rear Wheels
The rear wheels of a tractor perform various functions which are essential for efficient farming. One of the primary functions is to provide traction and power to the tractor. The larger the wheels, the more power can be transferred from the engine to the ground, allowing for better grip and more efficient movement. Moreover, they help to reduce soil compaction. The weight of the tractor is distributed across the larger area of the bigger rear wheels, minimizing the damage that would have occurred on the soil.
The Function of Front Wheels
The front wheels of a tractor perform the steering function necessary for maneuvering the vehicle. They also help to balance the tractor and suspension. However, they do not require as much power as the rear wheels and are relatively smaller. This is because the front wheels do not need to perform the same heavy lifting functions as the rear wheels.
Impact of the Terrain on Wheels Size
The size of tractor wheels also depends on the terrain on which they are used. For example, in areas with sandy soils, the wheels are larger to avoid problems of slippage, and for better traction on slopes, providing a solid foundation, particularly with heavier equipment like plows. Tractors that work on hillsides and mountainous areas may also require larger rear wheels for increased stability.
Conclusion
In conclusion, the size of the tractor's rear and front wheels is essential for its functions, which are specific to the terrain on which the tractor works. Bigger rear wheels help to provide more power, traction, and reduced soil compaction, while the front wheels are smaller and perform steering functions. Farmers should keep this important factor in mind when choosing a tractor for their agricultural operations.
