Disc Harrow are typically use for preparing the ground before planting. It design to disturb soil constantly all along the full working width. It is also use to clean up unwanted weeds are crop residue.

Specification

Usage of a Disc Harrow

1. Soil Preparation:
   • Used to break up large clods of soil left after plowing, making the soil finer and more uniform for planting.
2. Weed Control:
   • Helps in cutting and burying weeds, leaving the soil clean and ready for crops.
3. Incorporating Crop Residue:
   • Mixes crop stubble and residues into the soil, which decomposes and improves soil fertility.
4. Seedbed Preparation:
   • Levels and smoothens the soil surface, creating an ideal seedbed for planting.
5. Moisture Retention:
   • By breaking up the surface crust, the harrow helps retain soil moisture by reducing water runoff.
6. Post-Harvest Soil Management:
   • Used after harvesting to loosen and aerate the soil, making it ready for the next planting season.

Working Process

1. Attachment:
   • The Disc Harrow is attached to a tractor via a 3-point linkage system or drawn behind the tractor as a trailing implement.
2. Disc Blades Operation:
   • The blades of the Disc Harrow, mounted on axles, cut into the soil as the tractor moves forward. These discs can be smooth or serrated, depending on the type of harrow.
3. Soil Penetration:
   • The discs penetrate the soil, breaking up clods, cutting weeds, and mixing organic matter. The depth of penetration can usually be adjusted based on field requirements.
4. Uniform Soil Preparation:
   • The discs rotate and slice through the soil, ensuring a consistent, leveled field.
5. Speed and Efficiency:
   • Disc Harrows are designed for efficient and rapid soil preparation over large areas.
