A Disk Harrow is an agricultural tool with rotating, concave steel disks used to break up and aerate soil, preparing it for planting. The disks, set at an angle, cut into the soil, breaking up clods and crop residue. By adjusting the angle, the depth and aggressiveness of tillage can be controlled. The harrow improves soil structure by enhancing aeration, moisture retention, and root growth. It also helps with weed control by uprooting weeds and breaking up crop residue. Commonly used for soil preparation in large fields, the disk harrow ensures even soil leveling and promotes better seedbed conditions.
