Flail mower blade，Straw chopper blade，Wear-resistant hammer blade

Short Description:

• Made of high-strength wear-resistant steel, with surface treatment

(heat treatment or coating) for excellent impact resistance and wear resistance.

• The handle features a standard mounting hole for easy installation on

the rotor shaft of straw choppers, stubble cultivators, and shredders.

• The L-shaped/hammer-shaped body has a sharp edge; some models have a

wear-resistant alloy overlay to extend service life, compatible with mainstream

agricultural machinery brands such as Zhaoxian, Haofeng, and Bugu.

Product Detail

Product Tags

It is mainly used for agricultural straw chopping and returning to the field.

Installed on the rotor of straw choppers, stubble cultivators, and straw shredders,

it rotates at high speed driven by the tractor PTO to efficiently cut, crush,

and stubble-clear crop residues including corn, wheat, rice, sorghum, and cotton in the field.

The chopped straw is directly returned to the soil to improve soil fertility.

It can also be used for crushing forage grass and weeds, serving as a core wearing

part for mechanized straw returning and no-tillage seeding operations.

L-shaped/bow-shaped stalk cutters: Suitable for heavy-duty operations, some models feature a "wind-lifting angle" at the rear. During high-speed rotation, this structure generates an upward airflow, uprighting fallen vegetation for easier cutting, while also aiding in straw removal and preventing chassis blockage.

Straight/disc stalk combination: Suitable for chopping stalks of tall crops such as corn and bananas. Some models feature a double-sided cutting edge design, allowing for reversal after wear, doubling utilization.

The swivel cutter employs an advanced articulated structure design, with the blade connected to the cutter holder or cutter shaft via a hinge pin. This design allows the blade to automatically retract and avoid hard objects such as rocks and tree roots, effectively reducing the risk of breakage due to rigid impacts and significantly extending the service life of the cutter shaft and transmission system.

To ensure durability under harsh working conditions, the product is forged from high-strength diamond material or high-quality 65Mn spring steel. Through a rigorous heat treatment process, the blade hardness is controlled at HRC 48-54, ensuring a sharp and wear-resistant cutting edge; the handle hardness is maintained at HRC 38-45, balancing toughness and preventing brittle fracture at the blade shaft.

For high-wear conditions, some high-end models incorporate wear-resistant alloy blocks in the cutting edge or employ welding techniques, significantly extending the blade replacement cycle in sandy soil or high-fiber crop (such as cotton and corn) environments.
