Avalon ГРА-1.

Technical Analysis of the Avalon ГРА-1 Subsoiler

The Avalon ГРА-1 subsoiler is a robust implement engineered for deep, non-inversion tillage. Its primary function is the mechanical fracturing of the hardpan (plow pan), an impermeable soil layer that inhibits moisture infiltration and restricts root penetration, which can significantly limit crop yield potential.

Key Structural Components and Engineering Decisions

• Heavy-Duty Tines: The geometry of the tines is specifically optimized to minimize draft requirements while maintaining a constant working depth. Manufactured from high-strength alloy steel, these tines are capable of withstanding the high shear stresses encountered in compacted or stony soil profiles.
• Safety and Durability Mechanism: The unit features a protective system designed to safeguard the implement's frame and working tools against damage from buried obstacles such as large stones or root systems, ensuring operational continuity in adverse field conditions.
• Structural Integrity: The frame is engineered for superior rigidity, which ensures consistent penetration across the entire working width. The weight distribution is balanced to achieve optimal soil engagement while maximizing the tractive efficiency of the prime mover.

The practice of using the Avalon ГРА-1 is fundamental for restoring soil aeration and hydrological balance. By shattering the deep soil layers without inverting the topsoil, the implement promotes better moisture storage and protects the soil surface from wind erosion, as stubble is largely left intact on the field surface.
