A plough is used for initial soil cultivation to prepare the land for sowing seeds. It cuts, breaks, and turns over the soil, creating furrows and aerating the ground to reduce soil compaction.

The disc harrow is particularly effective for breaking up clods of soil and providing a smoother surface for planting. It is typically used after ploughing to prepare the soil before sowing seed or planting.

The power harrow is a high-efficiency agricultural tillage machine that can complete the tillage preparation of the high-quality seedbed before sowing at one time. It is best used with a high-power wheeled tractor.
