In the past, classic agricultural equipment, such as a plow, was used to fertilize the soil. These types of tools are based on the old approach to tillage technology, therefore they have been replaced by a disc harrow, which significantly simplified the work on large farms. It is mainly thanks to the disc harrow that farmers can prepare the field for sowing faster and more effectively, including crushing, loosening, tossing and mixing the soil.
What is a disc harrow?
Disc harrow is one of the basic agricultural machines for soil cultivation after plowing or harvesting. Like a plow, it is an implement that is steered by a two-wheeled machine such as a tractor or tractor. It is worth noting, however, that the disc harrow does not require a lot of power from it. The power requirement for a two-wheeled machine depends on the size of the disc harrow and the field conditions. More precisely, smaller disc discs with a working width of 3 m can be pulled by tractors with a power of up to 80 HP.
The plateau consists of sharp discs spaced in two rows spaced about 800 mm apart on a wide frame, a tilling roller and can be equipped with separately cushioned legs with a disc of smaller diameter. As for the order of the disc axles, the toothed discs are usually mounted in the front row and the full discs in the rear row. The number of circular discs depends on the width of your disc harrow model. Typically, you can find agricultural machines on the market with a disc section of 3m, 3,5m and 4m in length.
Advantages of using a disc harrow
The design of the disc harrow allows you to set the angle of inclination of the discs, so that the discs cut and turn the soil at a predetermined depth. Which, unlike the plow, has not been possible until now. Moreover, the disc harrow is resistant to disc clogging and can work closely with various types of cultivating rollers or even with an aftercrop seeder. As a result, after making a groove in the soil, you can immediately place the seeds in it using a seeder, and then it is buried.
The possibility of combining two agricultural implements allows to reduce the number of working passes in the field, which in turn results in better conditions for growth and prevents the appearance of problematic plow sole. On the other hand, the option of matching a specific type of roller to the disc harrow is extremely important in difficult conditions in the field. In wet, dry or stony soil, standard tubular rollers will not perform as well as a packer, crosskill or string roller.
What is the disc harrow intended for?
Disc harrows are actually agricultural machines that effectively replace the work of the plow. They are intended for shallow soil cultivation after the harvest, because they have steel toothed discs that can thoroughly mix harvest residues with the soil. Consequently, they can also stimulate the growth of self-seeding, i.e. cultivated plants.
However, these are not all tasks of the disc disc, namely its duties include crushing lumps, compacting and compacting the soil, removing weeds, mixing scattered mineral fertilizers as well as covering scattered manure and green fertilizers.
