Modern Disc Harrows: How to Choose Such an Important Aggregate?

The modern agricultural sector has long ceased to be a simplicity based on human power. Today, anyone who knows how to cultivate soil and harvest using various machines can make a profit from it. For example, literally every year, farmers plan to buy a disc harrow, without which it is practically impossible to process the soil effectively.

This small detail is used for shredding and evenly distributing plant residues, loosening the soil, preparing it for sowing, and also for stubble raking (surface treatment of the soil after harvesting, which is mandatory).

Why are quality harrows needed?

Disc harrows (rans) are primarily necessary to maintain soil quality throughout the year. The quality of the soil influences the yield and its value, which means profit.

Moreover, so-called raking harrows have other functions:

1. Disc harrows effectively shred plant residues such as straw, corn stalks, and sunflower.
2. They help improve soil structure.
3. Harrows are used for primary soil processing before sowing, creating optimal conditions for crop emergence.

After harvesting, harrows perform surface treatment, aiding in the distribution of plant residues and preventing weed growth.

Choosing Quality Raking Harrows

First of all, it is important to understand how many models can be found on the modern market. A good example can be the catalog at https://general-machines.ua/categories/lehka-dyskova-borona-general/, where the highest quality options are presented at affordable prices. As for additional selection criteria, attention should be paid to:

1. Soil type and operating conditions. Light and medium soils: lightweight and medium disc harrows with less weight and disc diameter can be used for such soils. Heavy and rocky soils: heavier harrows with large discs will be required to effectively process such soil.
2. Working width of the harrow. If small areas need to be processed, a harrow with a smaller working width (up to 2-3 meters) is suitable. For large fields, it is better to choose harrows with a working width of 4 m or more to process the soil faster.
3. Disc diameters. Small discs (up to 450 mm) are suitable for light soil processing and stubble raking. Large discs (from 450 mm) are used for deep soil processing, especially in heavy soils.

Attention can also be paid to the weight of the harrow, as well as the position of the discs, the type of connection to the tractor, and additional functions.
