GRAN PRIME air precision seed drill

Detail of the GRAN PRIME machine

Conceived to maximize yield

With 27- to 35-row models, the GRAN PRIME precision seed drill was developed for farmers who need quality and high yield in planting. In addition, it has an auto-transport function and a central hopper, features that increase its operational simplicity.

Planting in the ideal period is one of the factors that most impacts crops in terms of achieving the maximum potential yield. In the same sense, finishing planting within the appropriate window is also crucial for achieving high yield. With an auto-transport system, central seed hopper, flexible frame, high flotation pantographic rows to provide uniform planting depth and pneumatic metering units that ensure excellent seed singulation, the GRAN PRIME pneumatic precision seed drill was developed by KUHN for large-scale farmers who need high yield, easy operation and quality planting.

Your benefits

High performance and transport agility

Self-transport

Transport from the property headquarters to the fields and travel between planting sections are constant needs at large properties. With agility, safety and directly from the tractor cab, the operator controls the opening and closing system of the GRAN PRIME pneumatic precision seed drill, which, in less than two minutes, alternates between working and transport positions. Furthermore, the control box controls are sequential and intuitive, facilitating understanding and operation, ensuring agility and efficiency in movement, and increasing operational performance. In addition, the GRAN PRIME precision seed drill features up to 60% reduction in width (the total transport width is 6.10 meters), delivering high performance in planting and efficient transport.

High float row with flexible frame

The GRAN PRIME pneumatic precision seed drill planting rows have a high flotation range: they are 45 cm from the lowest to the highest point, ensuring uniform seed placement depth, preventing occurrences of seeds on the field surface or excessive planting depth, common situations in competitor models. Apart from featuring high-flotation rows, the frame of the GRAN PRIME pneumatic precision seed drill is articulated at two points and the machine is divided into three modules: a central one and two lateral ones, allowing for reaching 15º maximum flexibility. All of these features of the GRAN PRIME precision seed drill enable high operational efficiency planting, while at the same time ensuring a uniform plant stand and increased yield.

High technology that leads to profitability

Variable rate and row-by-row section control on an ISOBUS platform

The GRAN PRIME pneumatic precision seed drill has technologies that have proven to give farmers increased productivity. One of these technologies is the possibility of configuration with row-by-row section control, which controls the transmission of each seed row individually, reducing or eliminating the overlaps that are common at ends and edges. In this GRAN PRIME system, the rotation of the 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 GRAN PRIME is the variable-rate seeding. 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.
