disc harrowIt is a kind of ground preparation machine, which takes multiple groups of concave discs as working parts, the blade plane is perpendicular to the ground, and the random group forward direction has adjustable deflection angle. Compared with plows, it requires less power and higher operating efficiency. It can "rake instead of plowing", save energy, and can avoid over-tilling the soil. After raking, the soil can be fully mixed, which can promote the activity and chemical decomposition of microorganisms in the soil.

disc harrowIt is mainly used for tilling broken soil and leveling, and can also be used for stirring soil, weeding, mixing fertilizer, shallow tillage, loosening soil before sowing, covering seeds after sowing, etc. Widely used in traction topsoil tillage equipment.
Type of disc harrow: According to the coupling mode with the tractor, the disc harrow can be divided into three types: traction, suspension and semi-suspension. Heavy rake is generally traction or semi-suspended, there are three types of light rake and medium rake.
Traction disc harrow. Traction disc harrow is composed of traction frame, hydraulic system, harrow frame, harrow group, transportation wheel, etc. Some rakes are also equipped with a counterweight box.
Suspended disc harrow. The suspended disc harrow is generally composed of a harrow group, a harrow frame, a suspension frame and a deflection angle adjustment mechanism.
Semi-suspended disc harrow. The semi-suspended disc harrow is composed of suspension rack, hydraulic system, harrow frame, harrow group, transportation wheel, etc. Some rakes are also equipped with a counterweight box.
When the disc harrows, under the action of traction, the disc rolls forward, and under the action of the gravity of the harrow and the reaction force of the soil, it cuts into the soil to a certain depth. When the rake blade is rolling, under the combined effect of the blade and the surface of the rake blade, the soil is pushed and shoveled, and the soil undulates along the concave surface of the rake blade, which plays the role of breaking the soil, turning the soil and covering the soil.
