Kuhn Premia 4000 mounted mechanical seed drills provide high-quality results with seeding units able to seed with adapted coulter pressure, with solutions for mixed soil types and a covering harrow designed to work under variable conditions. The Premia gives users the possibility of working alone or in combination with a power harrow, reducing the number of passes over a field. Kuhn engineers have paid special attention to easy adjustments and simple access to adjustment points.

The Premia has been recognized for its application rate and precision. Its well-designed hopper has a wide opening for easy filling and cleaning. The flow rate can quickly be checked with the machine on the ground or without being hitched to a tractor through simple and easy-to-access adjustment points. An additional grass box, which also has a wide opening for easy filling, can be added for drilling small seeds.


Precise, Versatile Seeding

The volumetric seed metering by fluted rollers with built-in small seed rollers is suitable for all seed sizes and shapes. The helical grooves dose applications rates from 1- 400 lbs/acre. This distribution system is accurate and reliable throughout the whole operation. It provides regular seeding rates and distribution in the row even on slopes or uneven ground and is unaffected by vibrations. The Premia metering system is controlled by the seed drill’s two wheels via a 6-cam selector. This ensures reliable control and a regular flow through uniform rotation for small seeds with according low application rates.

Disc or Suffolk Coulters

Disc: The small angle of the disc reduces soil movement to a minimum when moving forward – very appreciable at high speed. Moreover, a cast iron seeding tip, positioned in line with the disc, consolidates the furrow and positions the seed precisely. The disc shape also facilitates penetration into the soil thus ensuring the required seeding depth. Suffolk: The shaped coulters guide the seeds into the ground with great accuracy and work especially well in hard and stony solids. The large distance of 13.85” (34 cm) between the rows limits the risk of clogging. The anti-clogging flap closes the coulter automatically.

Easy Adjustments

In mixed terrain, you can easily increase the hydraulically controlled application rate modulation by 10 or 20% if necessary. The flow test is particularly easy to use. The seed bar tilts via a parallelogram, making a large area available for the collection bucket. Flow rate can be checked with the machine on the ground, or even without being hitched to the tractor. Simply flip a lever for maximum access to carry out the calibration or for emptying the hopper. Afterwards, set the opening by a micrometric screw and carry out the number of turns required.

Well-Designed Hopper

allow for easy loading, the hopper has a wide opening with the cover even opening to more than 90°. That means an easy filling by bucket or big bag. The gas springs facilitate the opening of the cover even on machines which are four meters wide. The bottom of Kuhn seed drill hoppers is V-shaped. This reduces the residual quantity and ensures a uniform metering unit feed. The standard agitator is oscillating, thus handling the seeds with care.
