60Si2Mn heat-treated tillage blades, heavy-duty dryland blades, rotary tillage blades for clearing hard soil and barren hills, agricultural machinery accessories.
This product is a high-strength tillage blade (also known as a land clearing blade) specifically designed for agricultural cultivation. As a core working accessory for rotary tillers and tractors, it is mainly used for farmland reclamation, wasteland reclamation, grass cutting, and ridging operations. It is specifically designed to cope with complex and hard soil environments, making it an ideal choice for improving soil structure and enhancing tillage efficiency.
This product incorporates principles of mechanics and geometry in its design, primarily featuring C-shaped and L-shaped structural forms. The blade is straight and possesses excellent rigidity. The blade body consists of two parts: the handle and the blade tip.
Blade Handle: Equipped with a pair of precise fixing holes for a secure connection to agricultural machinery, ensuring it remains stable and doesn't shift under heavy workloads.
Blade Head: Utilizes an arc-shaped bending process, including both front-cutting and side-cutting blades. Its unique bending arc (approximately 119°-120°) and height setting effectively reduce resistance when cutting into the soil, resulting in better soil breaking and more consistent working depth.
To meet the demands for high-strength impact resistance and wear resistance, the blade body is made from high-toughness spring steel materials such as 60Si2Mn, 60Si2MnA, and 28MnSiB.
After rigorous heat treatment (martensitic phase transformation), the overall hardness of the product is controlled between HRC 42 and 48, ensuring that the blade is not easily broken or dulled under high-intensity impact. In addition, some models have a hot-melt alloy coating on the blade surface, which not only enhances wear resistance but also has a "self-sharpening" function—that is, it maintains the sharpness of the blade edge during operational wear, reducing power consumption and achieving energy saving.
This product is widely compatible with various large and medium-sized tractors, and is especially suitable for land reclamation, old grass cutting, and ridging in plains, drylands, and gentle slopes. It can effectively break up compacted soil layers, increase soil porosity, and provide a loose and breathable seedbed environment for subsequent crop planting.
