Harrow is an essential agricultural implement used for breaking up and smoothing out the soil surface after ploughing. Harrow helps to level the soil, control weeds, and prepare a fine seedbed for improved crop growth.

There are several types of harrows used in agriculture, each designed for specific soil and crop conditions:

• Disc Harrow: It is equipped with concave discs arranged in gangs. It is ideal for breaking clods and turning heavy soil. Commonly used after ploughing to mix crop residues and level the field.
• Tine Harrow (Spring Harrow): It has flexible or rigid metal tines. Useful for light soil preparation, weed control, and aeration. Suitable for shallow cultivation without inverting the soil.
• Chain Harrow: Made of chains linked to form a net-like structure. Used for spreading manure, covering seeds, and breaking crusted soil surfaces. Lightweight and commonly used for pasture maintenance.
• Spike Tooth Harrow: Consists of spikes or teeth attached to a frame. Effective for breaking soil clods and smoothing seedbeds. Suitable for light soil and seed covering.
• Power Harrow: A rotary harrow powered by a tractor's PTO. Works by rotating blades vertically to till and level the soil. Ideal for deep tillage and precise seedbed preparation.
