High-strength wear-resistant disc rake blades

The harrow blade is a key tillage component mounted on a disc harrow. Its core function is to further break up, level, mix, and weed the soil after plowing. It cuts the soil through high-speed rotation, preparing the seedbed for sowing, and is an indispensable part of modern mechanized farming. A high-quality harrow blade can significantly improve operational efficiency, reduce fuel consumption, and create an optimal soil environment for crop growth.

1、Materials: Made of high-quality high-carbon steel or alloy steel, and subjected to precise heat treatment processes (such as quenching and tempering) to give the rake blades extremely high surface hardness (usually up to HRC 40 or higher) while maintaining the toughness of the core, effectively resisting the impact of impurities such as sand, gravel, and tree roots, and preventing brittle fracture.

2、Sharp cutting edge: The cutting edge is precision ground, resulting in high initial sharpness, low resistance to soil penetration, and better soil cutting and breaking performance. This helps reduce the tractor's traction load and save fuel.

3、Powerful soil breaking and leveling capabilities：Through rotary cutting, large clods of soil are broken into uniform, fine particles. Simultaneously, the topsoil and subsoil are properly mixed, leveling the land and creating a soft, flat seedbed that promotes seed germination and root growth.

4、Long service life and economic benefits：Excellent wear resistance greatly extends the replacement cycle, reduces downtime and the frequency of parts replacement, and in the long run, saves users maintenance and operating costs.
