Levysiivilät

Levysiivilät, often translated as disc harrows, are agricultural implements used for soil preparation. They consist of a series of concave discs, typically made of hardened steel, mounted on gangs. These gangs are angled to cut, break up, and mix soil. Levysiivilät are employed for a variety of tasks including tilling, cultivating, and incorporating crop residues or fertilizers into the soil.

The primary function of a levysiivilä is to disrupt the soil surface, breaking clods and creating a more uniform seedbed. The angled discs slice through the soil, inverting and mixing it. This action helps to bury surface debris, aerate the soil, and conserve moisture. They can be used after plowing to further refine the soil structure or as a primary tillage tool in some situations.

There are different types of levysiivilät, varying in size, disc spacing, and gang angle. Smaller, lighter models are suitable for lighter soils and shallower cultivation, while heavier, larger models are designed for tougher conditions and deeper tillage. Some levysiivilät are mounted on the tractor's three-point hitch, while others are trailed. The effectiveness of a levysiivilä depends on factors such as soil type, moisture content, and the machine's settings.
