Rake discs – an efficient tillage tool for soil treatment

Short Description:

These agricultural machinery auxiliary harrow blades are precision forged from high-strength, wear-resistant steel and undergo a special heat treatment process, resulting in high hardness and excellent toughness. With a smooth surface and scientifically designed surface, they penetrate the soil smoothly and effectively break up the soil. Suitable for post-plowing soil breaking and leveling operations in various soil types, they effectively cut stubble and loosen topsoil, creating a good seedbed for sowing. Precise connection holes ensure compatibility with mainstream harrowing machines, making installation convenient and durable, making them a reliable choice for improving land preparation quality.

The harrow disc is the core working component of a tractor-mounted or suspended disc harrow. It is a disc-shaped blade that cuts, crushes, and turns the soil through high-speed rotation. It is mainly used for post-plowing land preparation, chopping crop residues, weeding, fertilizer mixing, and seedbed preparation. It is a key link between deep plowing and sowing, creating a loose, level, and moisture-retaining seedbed for crops.

1、Fine land preparation: Breaks up large clods of soil after plowing, levels the land, and forms a fine, uniform topsoil layer.

2、Stubble treatment: Sharp blades effectively chop up crop stubble such as corn and rice, promoting straw return to the field and decomposition.

3、Shallow mixing: Evenly mixes topsoil fertilizers, pesticides, or mulch with the soil to improve utilization.

4、Weeding and loosening the soil: Cuts weed roots, breaks up soil compaction, and improves soil aeration and water permeability.

5、Moisture retention and drought resistance: Creates a loose topsoil layer, breaks capillary action, and reduces soil moisture evaporation.

Main body material: Made of high-quality high-carbon steel (such as 65Mn) or alloy steel to ensure high strength and toughness.

Cutting edge treatment: The cutting edge undergoes a special quenching and tempering process, resulting in high hardness (up to HRC 40-50 or higher), strong wear resistance, and long service life.
