Classic sowing unit

AMAZONE sowing units have been uncompromisingly designed for high precision yet low maintenance. The easy handling saves start up times and increases the work rate. The sowing units are individually equipped with 60 l seed hoppers. For machines with Profi electronics, a fill level check is available.

The Classic sowing unit is ideally suited for sowing maize, sunflowers, beans, peas, cotton, etc., following the plough. The Classic sowing unit has a drop height of just 100 mm. These are the best pre-conditions for a high accuracy of work, good placement and enhanced field emergence.

Contour sowing unit

Smooth running for precise placement

The AMAZONE Contour sowing unit is ideally suited to both mulch sowing and when working after the plough. The outstanding feature of the AMAZONE Contour sowing unit is the low singling disc position with a drop height of only 140 mm. The sophisticated coulter technology creates a seed furrow, virtually free from any organic matter. The sowing coulter undercuts the clearing disc, resulting in a well re-consolidated wedge shaped groove.

These are the optimum pre-conditions but, under very light and sandy soils, the additional carrying wheel can be fitted on to the Contour sowing coulter to prevent it sinking too deeply into the soil. In this way the placement depth can be maintained significantly better.

The Contour sowing unit is guided via a longitudinal tandem, supported at the front by a one-sided press roller and at the rear by a V-press roller or Farmflex tyres. In this way the influence of the ground contours on the smooth ride of the unit is significantly reduced. Clods do not make the unit jump but it smoothly runs over them. So, any change in placement depth due to an uneven soil surface is minimised.

The front press roller has been deliberately mounted just on the one side so that the soil, thrown up by the fertiliser coulter, does not create additional movement on the unit. Thanks to the suspension in the longitudinal tandem, the unit can, on the one hand, optimally match the field contours and on the other hand it maintains a very smooth run at high forward speeds and on rough ground. Both factors result in an optimum accuracy of work with a precise placement depth. The weight distribution on the two press rollers in the longitudinal tandem can be adjusted. Depending on the soil conditions, always the right operating settings can be found.

EnviroSafe Airkit

EnviroSafe Airkit

The sowing of dressed maize seed using the well-known and widely used pneumatic vacuum sowing technology is, since 2009, in numerous regions of the world only approved for use when equipped with a suitable exhaust air guide system. In this way it is then ensured that waves of seed dressing laden air are not released into the atmosphere to protect both people and the environment. The AMAZONE Airkit has been certified by the Julius-Kühn Institute (JKI) and fulfils all regulations and is approved as an effective method of protection.

Singling – Precise, safe, simplest adjustment

Vacuum principle of the singling system

AMAZONE precision air sowing units operate according to the vacuum principle. The mechanically (ED Special) or hydraulically (ED Super) driven singling of the grains is carried out via a stripper finger which offers considerable advantages as it is virtually independent of forward speed and seed shape. The unique feature of the AMAZONE precision sowing units is the singling disc. The seeds are drawn by vacuum on to the raised holes and are delivered to the stripper. These raised holes function as an agitator because they protrude from the disc surface and thus bring a motion into the seed hopper. The raised holes have a conical shape and thus cannot be blocked by broken grains. These raised holes on the singling disc ensure that the seed leaves the disc in free fall so that it is not influenced by the disc as it turns. This is particularly important for the seed placement accuracy.

The AMAZONE stripper finger design is of particular advantage because it can easily be adjusted. Only 5 steps are quite sufficient to achieve the optimum position. The stripper finger adjustment has been proven to be insensitive to seed shape and speed. 85 % of all maize varieties available on the market can be singled with the same stripper finger setting!

For monitoring the singling process, there is either a large inspection window and/or an opto sensor positioned inside the housing. This serves as a seed detection system for the singling disc. In case, due to an error, the deviation is higher than 10 %, an error message is sent and displayed on the terminal.

High-quality plastic components and optimum sealing

High-quality plastic components made from different materials pair together and are responsible for the superb sealing between the vacuum chamber and the singling disc. This pairing together of different materials guarantees a long service life with optimum sealing.

Precise seed placement for the highest yields and efficiency

After the contactless fall of the seed from the disc, the secondary ejector ensures that the raised holes are absolutely clear. The design of the seeding mechanism results in a low drop height of only 100 mm in the Classic and 140 mm in the Contour sowing unit. This is an important pre-condition for precise seed placement.

A large variety of singling discs make possible the sowing of maize, sunflowers, rape, sugar beet, millet, cotton, etc. For each crop there are at least 2 singling discs with different hole sizes available for the optimum adjustment. The plastic singling discs are quickly exchangeable and offer great value for money.

Optional seed press roller

When the seed has been placed into the pre-shaped seed furrow, it is pressed by the roller, providing optimum seed/soil contact. This ensures a quick and reliable field emergence. Depending on the prevailing conditions, the downforce can be adjusted in three positions. Under very wet conditions the roller even can be completely removed, quickly and without tools.

Farmflex tyres

Ball-bearing mounted Farmflex rubber tyres in various sizes are available for the sowing units. The Farmflex tyre is best suited for sowing maize following the plough in conjunction with pre-closers.

V-press rollers

V-press rollers of different sizes are available for equipping the sowing units. They are potentially used for the mulch sowing of maize and sugar beet. Via the adjustment of the press angle, the opening angle and the opening width, the V-press rollers can be optimally adapted to the prevailing soil conditions. V-press rollers allow the optimum operation with and without following closers both in ploughed or mulch conditions.

Tractor wheel mark eradicators

When operating on heavy soils tractor wheel mark eradicators make sense. These loosen the compacted tracks behind the tyres. The position of the wheel mark eradicators can be adjusted horizontally and vertically.

Depending on soil type and implementation of the machine, the wheel mark eradicators can be equipped with different wear points. The overload safety device provides a maintained release force in all tine positions.
