3m disc harrow – which one to choose for your farm

Disc harrows, have become a popular choice in agriculture due to their ability to provide good quality topsoil cultivation. This implement effectively loosens the soil, improving its structure and allowing plant roots better access to nutrients. At the same time, disc harrows do not require high tractor horsepower, making them an economical solution. Their compact design makes them easy to handle and manoeuvre, which translates into higher productivity. The 3m disc harrow is effective in breaking up soil clods, which promotes the even distribution of organic matter, and helps control weeds. Thanks to these features, the machines have gained recognition among farmers and have become more popular in recent years.

3m disc machine variants.

3m disc harrows come in several basic variants, each dedicated to a specific type of cultivation. The first variant is the 3m disc harrow for shallow post-harvest cultivation, which is used to gently process the soil after harvesting. The next type is the cultivating harrows, dedicated to deeper treatments to loosen and prepare the soil before sowing. Cultivating and sowing harrows, on the other hand, combine cultivation and sowing functions, allowing both jobs to be carried out simultaneously. Although the differences in the design of these machines may be subtle to the unfamiliar observer, they are significant and affect the efficiency and effectiveness of a given agricultural operation.

The most important difference in a disc harrow is the spacing between the disc rows. In the case of tillage machines, where the harrow is designed to prepare the soil for sowing, this spacing is much smaller compared to a ‘disc’ for stubble cultivation.

The spacing between disc rows is related to the amount of residues. In the case of ploughing, where there is a large amount of residue, it is necessary to ensure a free flow of weight through the machine to minimise the risk of the 3m discs becoming clogged. For this reason, the discs are spaced at a wider spacing, up to 100 cm, in order to effectively deal with large amounts of plant material.

Which discs to choose for a 3m disc harrow?

There is now a noticeable trend towards increasing the diameter of discs in disc harrow designs. Until a few years ago, machines with working elements of around 500 mm in diameter were popular, used mainly for rapid stubble breaking. Nowadays, farmers, especially those running smaller and medium-sized farms, are turning their attention to versatility of use, resulting in a preference for large discs with a diameter of around 600 mm.

Machines with larger discs allow both shallow cultivation of stubble after cereals to a depth of 5-7 cm and effective operation in fields where cutting and deeper mixing is required, for example after maize with topdressed manure. Despite the higher price of machines with larger discs, due to the stronger frame design and brackets, farmers justify this choice economically by investing in one versatile implement.

It is worth noting that the diameter of the disc has a significant impact on the quality of the work. A smaller disc with finer serrations provides better and more uniform working results than a larger disc. Machines with large discs, increased spacing and longer poles, perform well in deeper cultivation with a lot of organic matter, being less prone to clogging. At the same time, the quality of shallow work in cereal stubble is usually satisfactory.

The rear roller is an essential component of the 3m disc machine.

The choice of roller on a 3m disc machine is an important element in determining the effectiveness of the machine. The roller plays a key role in determining the working depth of the discs, and is also responsible for levelling and compacting the topsoil. These actions aim to retain moisture in the soil and create optimum conditions for the germination of volunteer seeds and weeds.

The individual choice of roller depends on the specific soils on which the farmer farms. For light soils, experts recommend using lighter rollers with an incomplete core. This design ensures efficient soil flow and does not limit the working speed of the set, which is important on this type of soil.
