Heat treated vertical rotary tiller blade, wear-resistant stubble cutting blade, agricultural machinery and farmland accessories

Short Description:

This is a vertical stubble cutter designed specifically for agricultural machinery. The blade is forged from high-quality wear-resistant steel, with sharp edges, high hardness, and strong wear resistance. Its unique vertical structure can penetrate deep into the soil, efficiently crush the remaining hard straw such as corn and cotton after harvesting, and complete stubble removal and deep rotary tillage operations in one go. Not only does it significantly improve the efficiency of soil fragmentation and land leveling, but it also reduces tractor power consumption, making it an indispensable and efficient accessory for conservation tillage and fine farmland leveling.

The vertical blade, an essential component of modern agricultural machinery, is usually installed on rotary tillers, cultivators, or harvesters. It is powered by a tractor and efficiently completes multiple tasks such as rotary tillage, stubble removal, ridge formation, and debris cutting in the field.

This product emphasizes durability and wear resistance in its design. It is mainly made of high-quality 65Mn manganese steel or 60Si2Mn spring steel through forging processing, and the material has excellent toughness and wear resistance. In order to further improve the product life, vertical knives are usually subjected to strict overall heat treatment or local quenching processes to control their hardness between HRC38-45. Some key parts such as the handle and blade also have finer hardness standards (such as handle 40 ± 3, blade 42 ± 3), ensuring that the blade remains sharp and not easily broken or deformed during high-intensity field operations.

In terms of structural form, vertical knives are distinguished from traditional horizontal knives by their unique vertical installation method. Taking common models as an example, such as the JF-15 * 100 vertical rotary tiller, its thickness can reach 15mm, width 100mm, length 270mm, and a single weight of about 2.22kg, demonstrating its solid and heavy characteristics. In addition, there is a vertical combination cutting tool design specifically designed for harvesters, consisting of a moving blade, a fixed blade, and a blade guard. This structure can cut off the straw, vines, and weeds that accompany the crop into the cutting edge, effectively preventing debris from entangling and improving the smoothness of the operation

Vertical knives are widely used in various agricultural machinery matched with four-wheel tractors or hand-held tractors. Whether it is a reclamation knife used for cultivating wasteland or a stubble removal rotary tillage knife used for returning straw to the field, it can play a core role in protective tillage and fine land preparation in farmland with its powerful cutting ability. At present, the vertical knife products on the market support customized production and can provide multiple specifications to choose from according to different agricultural needs and models
