The perfect precision seed drill for all crops

With 7- to 17-row models and versatile configurations, the PRIME is the perfect pneumatic precision seed drill for all fields. Moreover, its precise seed metering and high-flotation rows ensure uniform field germination.

A pneumatic precision seed drill perfect for all fields and easy to calibrate: based on these guidelines, KUHN developed the PRIME. In sloping fields, with contours or on terraces, the rows tend to suffer misalignment, compromising the quality of the planting stand; however, in the PRIME, the proximity between the cutting disc, the fertilizer and seed rows is the smallest in the category, allowing farmers to ensure uniformity and increase yield in their crop, even in the most rugged terrain. Moreover, with the seed hoppers mounted along the frame, weight is evenly distributed, unlike some competitor models which centralize the hoppers. This all ensures that the PRIME pneumatic precision seed drill performs very high quality planting, keeping seed singulation close to 100% and placement depth uniform, an ideal combination of factors for a perfect plant stand.

Your benefits

Perfect plantability in any conditions

Fertilizer rows close to the seed rows

The PRIME pneumatic precision seed drill is a compact machine, with reduced distance between cutting discs and planting rows, a feature that prevents misalignment in furrows when planting in areas with a steep slope or contours. The perfect alignment between furrows gives plants access to the fertilizer deposited in the soil by means of a good root system. The proximity between PRIME rows also assures that, when passing over level drops in the fields, all seeds are deposited in the furrow, without being uncovered, resulting in high yield and return on investment for the farmer.

Adjustment in the depth gauge wheel

Among other features, the PRIME pneumatic precision seed drill has the following characteristics: its set of depth gauge wheels and press wheels were designed with limiting bands near the center of the discs, maintaining uniform depth of the furrow. In addition, the assembly features a spacer which sets the depth gauge wheels apart from the furrow opener discs, increasing the space between them and enabling planting in fields with clay soil or wet straw without bushes. Add to this the fact that the depth gauge wheels of the PRIME pneumatic precision seed drill are independent and have a high flotation range, performing perfect planting in any type of terrain; in addition, its press wheel is robust and developed based on a design that leaves no space for straw to enter, preventing bushes and the resulting “raking effect”.

Row-by-row section control and variable-rate

Precision agriculture gives farmers demonstrable input savings and maximizes the productive potential of each area. With this in mind, the PRIME pneumatic precision seed drill was developed with technologies that give farmers increased yield. The PRIME pneumatic precision seed drill can be optionally configured with row-by-row section control, an option that controls the transmission of each seed row individually, reducing or eliminating the overlaps that are common at ends and borders. In this system, the rotation of the PRIME’s pneumatic metering unit is interrupted by means of an electric clutch, providing seed savings and a significant increase in yield. Another technology to help the farmer which is available in the PRIME is the variable-rate for seed and fertilizer. This technique delivers inputs according to the specific needs of each crop through application maps, not working with averages like conventional agriculture. Both systems are controlled via the ISOBUS platform: a technology that facilitates connectivity with all tractors on the market and eliminates the need for additional monitors in the cab. With the ISOBUS system, the operator monitors and controls the PRIME pneumatic precision seed drill in the same operating system as the tractor.

Low maintenance with operational safety

Flexible shaft transmission

The transmission of the seed row is a key item in ensuring distribution quality. Conventional systems with chains and gears or drive shafts do not deliver enough precision to ensure perfect singulation, because they have excessive gaps that compromise spacing between seeds. Unlike these, the PRIME pneumatic precision seed drill has a flexible shaft in the transmission of rows that dispenses with the need for chains and drive shafts. This innovative system is sealed, requiring no lubrication and no type of maintenance. It is a robust and high performance assembly, developed exclusively for the pneumatic metering unit, which guarantees precise and safe transmission, favoring a high quality plant stand and increased productivity for the farmer.
