Disc blade 3490467
**Disc Blade:** A vital component of disc harrows and tillage implements, the disc blade is a hardened, concave, circular steel plate with a sharpened outer edge. Mounted individually on axles within gangs at an angle, its primary function is cutting, loosening, and inverting soil. As pulled forward, the angled blade slices through the soil and crop residue, lifting and turning it over. The concave shape aids penetration and soil pulverization. Key applications include primary tillage (breaking hard ground), secondary tillage (refining seedbeds), weed control, residue incorporation, and seedbed preparation. Its effectiveness lies in handling tough conditions, cutting residue, and improving soil structure, though it can cause compaction. Proper blade size, spacing, angle, and weight dete rmine performance.
The rake disc is the core working component of a disc harrow; it is a steel disc with sharp blades and a specific concavity. Its main function is to cut, turn, and break up the soil by rotating, while simultaneously cutting weed roots and stems, mixing stubble and fertilizer, and preparing a flat, loose, and clean seedbed for sowing. It is an indispensable key auxiliary component in modern agricultural land preparation.
