The disc plow is suitable for deep tillage and gypsum fertilization, while the disc harrow is suitable for shallow treatments such as loosening and preventing soil compaction, with different operating techniques and difficulties. Although disc plows and disc harrow are both equipment used for plowing and loosening farmland, they have significant differences in structure and usage.

What are the reasons why the disc harrow blade does not enter the soil or the harrow depth is not enough? There may be several reasons why the disc harrow blade does not penetrate the soil or the harrow depth is insufficient.

I. Technical requirements for disc harrow operation(1) The rake depth meets the local lawn planting requirements and is even.(2) During homework, there should be no missing rake or soil blockage.(3) After homework, it is required that the surface and ditch bottom be leveled, the soil be loose and fragmented, and the residue be well covered.

Disc harrows are divided into three types: heavy, medium, and light according to the weight of the entire machine and the diameter of the harrow blades. Disc harrow is generally composed of a harrow group, frame, angle adjuster, traction or suspension device, etc.

The core difference between the middle disc harrow and the heavy disc harrow lies in the operational intensity, structural design, and applicable scenarios. Essentially, it is a "medium strength" and "high-strength" soil preparation tool that matches different soil conditions and cultivation needs.

In today's rapidly evolving agricultural improvement, the combination of a tractor with disc harrow remains one of the most essential and widely used machinery systems worldwide. As global food demand continues to rise and sustainable farming practices become increasingly critical.

As global agriculture shifts toward precision and sustainability, the disc harrow industry is experiencing robust growth in 2026, fueled by advanced material applications, smart technology integration, and rising demand for efficient soil tillage solutions.
