How to Choose a Seed Drill

Before choosing a seeding machine, it’s important to understand one key distinction.

Seed drills are designed for the seeding of cereals, oilseed rape, grasses and cover crops. Precision planters are used for the precise seeding of individual seeds of crops such as maize, sugar beet, sunflower and soybean.

The crop you grow is the main factor in deciding which machine you need. If you are seeding cereals, oilseed rape or cover crops, a seed drill is the right choice. The remainder of this guide focuses on selecting the most suitable seed drill.

The tillage system is one of the most important factors when choosing a seed drill. Different machines are designed for seeding into conventionally prepared seedbeds, minimum tillage systems, strip-till or direct seeding into untilled soil.

Although different seed drills may have similar working widths, hopper capacities or even a similar appearance, their design is optimised for specific field conditions and farming systems. These differences are not always obvious at first glance. Selecting the right machine for your cultivation system is often more important than comparing technical specifications alone.

Conventional seeding remains one of the most widely used crop establishment methods. It is typically applied where ploughing or intensive seedbed preparation is carried out before seeding to create a uniform seedbed with a fine soil structure.

The main advantages of this system include favourable conditions for crop emergence and lower demands on the seed drill itself. A well-prepared seedbed ensures excellent seed-to-soil contact and accurate seed placement at the required depth. On the other hand, conventional seeding generally involves a higher number of field operations, increased fuel consumption and greater disturbance of the soil structure. In drier regions, more intensive tillage may also lead to higher soil moisture loss.

If you use a conventional farming system, you should choose a seed drill designed to operate in a uniformly prepared seedbed. Key selection criteria include the required daily field capacity, the method of seedbed preparation and the size of your farming operation.

Several seed drill designs are suitable for conventional seeding. Small and medium-sized farms can benefit from the SONIQ ON and KATARA KN_S seeding combinations, which combine seedbed preparation and seeding in a single pass. Larger farms requiring high daily output often choose the EFECTA CE, a wide-working seed drill designed for seeding into prepared soil.

Minimum tillage represents a compromise between intensive soil cultivation and direct seeding. Its objective is to reduce the number of field operations, retain part of the crop residue on the soil surface and create suitable conditions for successful crop establishment.

The main benefits include lower tillage costs, improved erosion control and better soil moisture conservation. Leaving part of the crop residue on the soil surface also helps protect the soil from overheating and reduces moisture evaporation. On the other hand, minimum tillage places greater demands on residue management and the correct timing of individual field operations.

If your farm uses minimum tillage, you should select a seed drill capable of handling larger amounts of crop residue while maintaining high-quality seed placement, even in less intensively prepared soil.

The OMEGA OO_L and OMEGA OO_FL universal seed drills are an ideal choice for minimum tillage systems. Their front disc section prepares the seedbed directly during seeding, allowing them to perform reliably under a wide range of soil conditions and different levels of previous tillage intensity. The OMEGA OO_FL also enables fertiliser application or the seeding of a second crop in a single pass thanks to its dual-compartment hopper.

If you use strip-till technology, you need a seed drill that accurately follows the cultivated strips and fully utilises their potential. When selecting a seed drill for strip-till, not only seeding accuracy is important, but also the ability to apply fertiliser and operate effectively in fields with large amounts of crop residue.

Strip-till is based on cultivating narrow strips of soil into which the seed is subsequently placed. The area between the rows remains undisturbed, while most of the crop residue stays on the soil surface. This system reduces the number of field passes, enables targeted fertiliser placement and minimises soil disturbance compared with full-width tillage.

The challenges of strip-till include higher demands on accurate strip preparation, precise alignment of subsequent operations and effective residue management. The success of the system largely depends on well-prepared strips and the precise execution of every following field operation.

The MATADOR MO is specifically designed for strip-till farming. It performs strip cultivation, fertiliser application and seeding in a single pass.

Direct seeding is a crop establishment system in which crops are sown without any prior soil cultivation. The seed is placed directly into stubble, cover crops or the crop residue of the previous crop. Soil disturbance is limited to the narrow seed slot created by the seeding coulter.

The main advantages of direct seeding include minimal soil disturbance, reduced water and wind erosion, fewer field passes and maximum retention of crop residue on the soil surface. This approach also helps conserve soil moisture, supports soil biological activity and promotes the gradual decomposition of crop residue, contributing to the long-term improvement of soil structure.

However, direct seeding places high demands on the entire farming system. Effective residue management, the use of cover crops, a well-designed crop rotation and continuous soil monitoring all play an important role. As with any cultivation system, success ultimately depends on the specific conditions of each farm and sound agronomic management.

If you farm using a direct seeding system, it is essential to choose a seed drill capable of operating in large amounts of crop residue while ensuring reliable seed placement in untilled soil.

The DIRECTO NO and DIRECTO NE seed drills are specifically designed for direct seeding. Their design enables crop establishment without prior seedbed preparation while ensuring accurate seed placement even under demanding field conditions.

The farming system is not the only factor to consider when choosing a seed drill. Soil type, the amount of crop residue and the field conditions in which the machine will operate are equally important. These factors often determine the most suitable type of seeding bar.

Disc seeding coulters are among the most widely used solutions in modern seed drills. They provide excellent coulter guidance, outstanding ground contour following and reliable performance in fields with large amounts of crop residue. They are suitable for conventional seeding, minimum tillage and direct seeding alike. Disc seeding coulters are used on the OMEGA OO_L, OMEGA OO_FL, EFECTA CE and DIRECTO NO seed drills. This type of seeding section is also available separately as the CORSA CN seeding bar.

Tine seeding coulters are a versatile solution suitable for conventional seeding as well as various minimum tillage systems. Their main advantages include a simple design, lower draft requirement and excellent performance in stony conditions. Thanks to their ability to work effectively across a wide range of field conditions, they are particularly popular with farms looking for a universal seeding bar suitable for different cultivation systems. This concept is represented by the GIRONA GN seeding bar.

When choosing a seed drill, it is tempting to focus primarily on working width. However, a wider machine does not automatically mean higher efficiency. The key is to match the seed drill to your tractor’s power, the size of your farming operation and the length of your seeding window.

As a general rule, it is better to choose a working width that your tractor can handle comfortably under all conditions than to operate a larger machine at the limit of its capabilities. Tractor power affects not only working speed, but also the ability to maintain the required seeding depth, perform consistently in hilly terrain and operate efficiently in wetter field conditions.

For small and medium-sized farms, or for fields with irregular shapes, seed drills with working widths of 3 to 6 metres—such as the SONIQ ON, KATARA KN_S and OMEGA OO_L—are often the most practical choice. Larger farms operating extensive fields can take full advantage of wide-working machines such as the EFECTA CE and DIRECTO NE, which provide high daily output while maintaining excellent seeding quality.

Logistics should also be taken into account. As working width increases, daily field capacity grows, but so does the importance of efficient seed and fertiliser refilling, transport and overall work organisation. The objective is therefore not to choose the largest seed drill available, but the one that enables crops to be established at the optimum time without unnecessary compromises.

In recent years, there has been growing interest in combining multiple field operations into a single pass. In addition to seed placement, more and more farms are applying mineral fertiliser or simultaneously seeding a second crop or a cover crop. This approach helps make better use of short seeding windows, reduces the number of field passes and improves overall operational efficiency.

If you plan to apply fertiliser during seeding or intend to introduce cover crops or companion crops in the future, it is advisable to choose a seed drill that is designed for these applications.

The OMEGA OO_FL features a dual-compartment hopper, allowing simultaneous seed placement and fertiliser application, or the seeding of two different crops in a single pass. For simpler applications involving small seeds or cover crops, the ALFA DRILL seeding unit can also be mounted on selected BEDNAR machines.

When selecting a seed drill, consider not only your current requirements but also how your farming system is likely to develop in the coming years.

Every farm has different conditions and different requirements for crop establishment. If you are still unsure which seed drill best suits your needs, the following typical farming scenarios may help you make the right choice.

New or Used Seed Drill?

Purchasing a used seed drill can be a good solution, particularly for smaller farms or growers looking to reduce their initial investment. However, it is essential to pay close attention to the machine’s technical condition, as the wear of individual components can have a significant impact on seeding quality.

Before purchasing, we recommend carefully inspecting the condition of the seeding coulters, press wheels, bearings and other wear parts. It is also important to check that the metering system and electronic components are functioning correctly, as well as ensuring compatibility with the terminals and control systems already used on your farm. The availability of spare parts and reliable service support for the specific model should also be considered.

A new seed drill, on the other hand, provides the confidence of a known technical condition, full warranty coverage and the latest design innovations. Modern seeding units contribute to improved ground contour following and more uniform seed placement. Many current models also support advanced technologies, including remote calibration and diagnostics through the BEDNAR FARM LINK system on selected machines.

When making your decision, do not compare purchase price alone. Future operating costs, crop establishment quality, service availability and the length of time you intend to use the machine are equally important factors.

Technical specifications and product catalogues can tell you a great deal, but the true capabilities of a seed drill are best demonstrated in your own fields. A field demonstration under real farming conditions will show how the machine performs in your soil, handles your crop residue and fits your farming system.
