4 disc harrow
The 4 disc harrow represents a significant advancement in agricultural equipment, designed to efficiently prepare soil for planting through comprehensive ground preparation. This implement consists of four rows of carefully angled discs, typically ranging from 18 to 24 inches in diameter, mounted on a robust frame. Each row works in tandem to perform multiple soil preparation tasks simultaneously. The front discs break up and slice through crop residue, while the rear discs further pulverize soil clumps and level the field surface. The implement's adjustable gang angles allow farmers to customize the intensity of soil disturbance based on specific field conditions and requirements. The 4 disc harrow excels in both primary and secondary tillage operations, effectively incorporating crop residue into the soil while creating an ideal seedbed structure. Modern designs often include hydraulic systems for easy depth adjustment and transport, along with maintenance-free bearings that significantly reduce downtime. The implement's versatility makes it suitable for various soil types and conditions, from heavy clay to lighter sandy soils, and it can handle both conventional and conservation tillage practices. With working widths typically ranging from 8 to 30 feet, these harrows can efficiently cover large acreages while maintaining consistent soil preparation quality.
