Agricultural machinery accessories: harrow blades
Harrow blades are an indispensable key accessory in modern agricultural tillage, mainly installed on agricultural implements such as disc harrows and notched harrows. Their core functions are to break up soil clods, level the land, cut weed roots, and mix soil with crop residues, creating a loose, level, and fertile seedbed for subsequent sowing, irrigation, and crop growth. A high-quality harrow blade can significantly improve operational efficiency and reduce traction resistance, serving as a fundamental guarantee for achieving high-standard land preparation and increased agricultural production and income.
1、Material: Made of high-quality high-carbon steel or alloy steel, and processed with advanced heat treatment technology (such as quenching and tempering) to give the rake blades extremely high hardness (usually HRC can reach above 40), while maintaining the good toughness of the disc body, effectively resisting the wear of sand and hard soil, preventing brittle fracture, and having a long service life.
2、Spherical Design: The scientifically designed radius of curvature ensures optimal soil entry angle and tilling effect as the rake blades roll forward, easily cutting into hard soil while achieving excellent soil breaking and covering functions.
Sharp Cutting Edges: The precision-polished cutting edges have high initial sharpness, easily severing plant roots and stems, reducing entanglement, lowering traction resistance, and thus saving tractor fuel consumption.
