The Industrial Revolution in the 19th century accelerated the development of agricultural machinery. Steam-powered engines replaced animal power, making it possible to operate larger and more efficient equipment. Mechanical reapers, threshers, and tractors emerged, reducing the reliance on manual labor.

One of the most significant inventions of the time was the internal combustion engine, which eventually powered modern tractors. These machines became the cornerstone of farming, capable of plowing, planting, and transporting goods with unprecedented speed and efficiency. Farmers were no longer constrained by the limitations of human or animal strength.

Types of Modern Agricultural Machinery

Today, agricultural machinery encompasses a wide variety of specialized equipment designed to meet diverse farming needs. Some of the most widely used machines include:

1. Tractors

The most iconic piece of farm machinery, tractors are versatile vehicles used for plowing, planting, hauling, and more. They come in various sizes and power capacities, suitable for both small-scale farms and large industrial operations.
