Smallest width for self-supporting unit
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.
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.
Optimising the genetic potential of seed
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.
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.
Greater precision in seed depositing
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.
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.
Depth limiter Side Wheel
The Side Wheel depth limiters can be mounted on the side of the seed disks, to render a more uniform depth in the laying of seeds in the furrow. Additionally, they are equipped with a spiked rim that prevents clogging due to material build-up during the seeding and a tandem beam, responsible for keeping it always in contact with the soil, which provides excellent performance even on irregular ground.
Titanium seed spreader
The Titanium seed doser provides greater efficiency in seed dosing, reducing the percentage of double seedlings or germination failures, increasing the farmer harvest profitability.
When dealing with compacted soils with a large number of stones, the disc and knife set can also be used. In this option, the disc near the knife is capable of being lifted to overcome the stones it finds in the way, and also cut the straw, dragging together the knife that returns after this to the furrow, according to the depth previously set.
The Non-Stop system that is automatically disabled and then enabled by spring, ensures the work in total safety and comfort, even in soils with the presence of stones. When in contact with an obstacle (stones, roots...), the knife tilts backward, compressing the upper spring that, once the obstacle has passed, returns to its original work position.
The row marker is rugged, allowing a more accurate and safe operation, avoiding the coincidence of rows and path errors.
The automatic section control interrupts the transmission of the seed row with the use of an electric clutch, ensuring the saving of seeds.
Non-Stop hydraulic knife
The Non-Stop knife with hydraulic disabling is efficient and rugged. The closed hydraulic circuit allows the simultaneous adjustment of all rows. Its adjustment is quick and ergonomic, and the pressure is adjusted through a quick coupling with direct reading on the manometer located in front of the planter.
Fertisystem seed metering dispenser
The Fertisystem dosers are known for working with one screw always full and for having a buffer chamber that overspills uniform and homogeneous quantities of fertilizer, regardless of the grain size and the topographic variations of the crop.
