A disc harrow is used to break up, crumble, and mix the soil after plowing, creating a smooth and fine seedbed that promotes good plant growth.

Harrowing should be done when the soil is dry enough to avoid clumping, typically in the spring or autumn after plowing or before seeding.

Harrowing is typically done at a depth of 5–15 cm.

A disc harrow is best used after plowing to break up the soil crust, level the ground, and mix organic material before seeding.

Harrowing improves soil structure and prepares it for seeding.
