Core Working Functions
Soil Crushing and Leveling: Using concave discs to roll and cut into the soil, breaking up clods and ridges after plowing, and making the surface level and loose.
Weed Control and Stubble Management: Cutting off grass roots or crop residues, stirring and turning the topsoil, and removing field weeds and residues of previous crops.
Mixing and Covering: Mixing fertilizers, straw, or crop residues into the soil, covering the surface to reduce moisture evaporation, and improving soil aeration and water retention.
Applicable Working Scenarios
Post-Plowing Land Preparation: Mainly used for crushing soil after plowing to prepare seedbeds for sowing.
Pre-Sowing Preparation: Loosening soil and removing weeds before sowing, breaking surface compaction, and ensuring a suitable environment for seed germination.
Post-Harvest Treatment: Used for shallow tillage and stubble management after harvest, achieving straw chopping for returning to the field and reclamation of wasteland.
Soil Adaptation and Types
Adaptation to Heavy Clay Soils: Heavy disc harrows have strong soil penetration ability, particularly suitable for heavy clay soils, wasteland, and weed-infested fields.
Differences Between Types: Notched disc harrows have stronger crushing ability, suitable for high-stubble fields; light harrows are suitable for fine land preparation on cultivated land and light to medium soils.
