Transporting machines and implements from one area to another with ease and safety is a need that has been growing due to a new reality of field work. In this sense, the reduction of the transport width for easier passage through gates, on bridges or even narrow roads is crucial. With this in mind, the pneumatic PRIME AT planter was developed aiming for an efficient transport solution. Its sturdy structure, with hoppers mounted along the chassis, levels the weight distribution throughout the machine structure, equalizing the pressure of the pantograph frames on the ground. Besides, featuring a high cutting power, central chassis articulation and high fluctuation lines combined with the Precision Planting drills, ensures high quality planting regardless of soil or straw conditions.

Convenient and efficient transport

Transporting the planter from the headquarters of the property to the crops, as well as its displacement between the planting plots located at different distances, passing through gates and narrower bridges, is a need that has been growing over the last few years. In the pneumatic PRIME AT planter, the operator can control the opening and closing of the machine with great agility and safety, directly from the tractor cabin. With the aid of two double-action valves on the tractor, the pneumatic PRIME AT is switched from its working position to transport position in less than a minute, ensuring that its displacement happens safely and efficiently.

Chassis with central articulation

The mechanical PRIM AT planter enables planting with high operational efficiency, ensuring a uniform plant stand and consequent increase in productivity. The presence of a central joint allows the planter to oscillate 8° downwards and 13° upwards. This characteristic, combined with the high fluctuation of the pantographs, makes the lines always in contact with the soil, ensuring a quality planting, regardless of soil or straw conditions. Therefore, regardless of the relief condition, the mechanical PRIME AT planter is capable of perfectly copying terrain irregularities and contour lines, providing a uniform seed deposition depth, which is essential for perfect seed germination.

Greater robustness

Bearing in mind the most challenging working conditions that a planter can encounter, the mechanical PRIME AT was developed with wider and more robust wheels to provide greater load capacity to withstand day-to-day work in the field and transport with total safety and agility. The resistance also extends to the new concept of self-transporting chassis that had as its principle to provide a compact and robust structure, ensuring a longer useful life for the whole set. The weight distribution along the chassis of the mechanical PRIME AT planter results in a stable machine and allows all planting lines to receive the same load, helping to cut and penetrate harder soil. This is made possible due to the fact that mechanical PRIME AT seed reservoirs are distributed over the entire length of the chassis.

High cutting power

The mechanical PRIME AT planter has a combination of elements that results in excellent cutting power, even in conditions where the volume of straw reaches high levels. Its cutting disc has sufficient vertical fluctuation and turning radius to perform shearing work efficiently and with quality. Efficient straw cutting is very important so that the seeds are not involved by it, in which case contact with the soil would be prevented and, consequently, germination and access to nutrients would be hampered. In addition, the mechanical PRIME AT planter offers options for different soil conditions and smooth and turbo cutting discs. The latter, in addition to cutting the straw, provides movement and unpacking of the soil, avoiding the mirroring of the furrow and facilitating the penetration of the fertilizer and seed furrow openers.

Fertilizer dosers

Dosing the fertilizer accurately and evenly, in addition to ensuring its correct positioning at the base of the furrow, are fundamental factors to eliminate waste and maximize the absorption of nutrients by the plants. For this purpose, the pneumatic PRIME AT has the Toplanting fertilizer doser as standard, which, with its double endless system, achieves high spread stability both in volume and in pulsation, distributing the same amount of fertilizer in any degree of inclination, longitudinal or lateral. As an option, the Fertisystem dispenser is available, which stands out for working with an always full screw and having a damming chamber, which overflows quantities of uniform and homogeneous fertilizers, regardless of the grain size and topographic variations of the crop.

Low soil turnover

The mechanical PRIME AT planter has a furrow opener with outdated double discs (with different sizes and concentric axes), optionally for the fertilizer line and as standard for the seed line. Among the benefits of this concept, in relation to systems with mismatched discs (with the same size and misaligned axes), we can mention the greater capacity of penetration into the soil and, at the same time, the lower turning of the furrow, as they have a smaller angle between the discs. This characteristic is fundamental because, when carrying out an operation with less soil movement, the mechanical PRIME AT planter guarantees all the benefits of direct planting, resulting in increased productivity for the producer.

Simple and ergonomic adjustments

The mechanical PRIME AT planter has the same concept as the KUHN planter line when it comes to adjustments and calibration. Like other planters and seeders, the main adjustments of the mechanical PRIME AT do not require the use of tools, as they are equipped with mechanisms that value the operator's agility and safety. Adjustments in fertilizer and seed transmission, depth of seed deposition and compactor pressure are the main examples of necessary and fundamental calibrations for planting. With that in mind, the mechanical PRIME AT planter has systems that speed up the adjustment of the machine and facilitate the daily life of the producer.

High flotation pantographs

The ability to follow changes in relief during planting is essential for maintaining the constant depth of seed deposition in the furrow. With 45 cm of width, the pantographic lines of the mechanical PRIME AT planter have one of the biggest fluctuations on the market, capable of providing an efficient planting in any relief condition and straw volume. The four movable points combined with an internal spring system with adjustable pressure, allows the vertical oscillation necessary for planting with quality in the most challenging terrain conditions. The presence of technologies that do not require daily lubrication of the pantograph joints saves time and are exclusive features that increase the productivity and useful life of the equipment.

Mechanical seed dispenser

The mechanical planter PRIME AT features traditional honeycomb disks of the KUHN seed dispensers to enable a good plant stand. In this system, there is a disc with grades regarding the thickness, diameter and number of holes for each crop. The Titanium feeder is available as an option, which, through its conductive brush system, minimizes mechanical damage to the seeds and favors precision in dosing. Regardless of the type of doser chosen, the characteristic plantability of the KUHN models will provide the ideal conditions for depositing the seeds at the desired depth and perfect closure of the furrow for rapid moisture absorption and subsequent seedling germination.

Planting monitoring

With intuitive settings for operation, the MP36 seed monitor stands out for the accuracy of the information and the simplicity of its use. Thus, it is possible to simultaneously visualize the seed fall in up to 36 lines, in addition to providing data on seeds per linear meter, seeds per hectare, working speed and total planted area. Its illuminated screen allows night work, while an audible and luminous alarm warns of the occurrence of failures for greater convenience and total safety during planting. In addition, it allows communication with the Fieldview system to generate planting maps and report faults per line.

Perfectly packaged seeds

The uniformity of seed deposition in the soil is as important as its spacing within the furrow. Planter - the depth limiter assembly of the mechanical PRIME AT - is designed with closed-rim limiting wheels that help keep the earth in the furrow. The possibility of adjusting the angle between the limiting wheels provides a better performance during planting, regardless of the amount of straw in the soil. Its high independent oscillation capacity improves its efficiency in monitoring irregularities in the most varied types of soils. Finally, the densification of the soil next to the seeds is carried out by a robust compactor that has pressure and angle of action adjustment.
