A power harrow is a tractor-mounted agricultural tool used for secondary tillage, primarily for breaking up and refining the soil after primary tillage.
PURPOSE:- The main function of a power harrow is to break down clods of soil, level the surface, and create a consistent texture, which improves seed germination and seedling growth.
MECHANISM:- Power harrows typically use a series of rotating blades or discs that agitate and break up the soil.
