Cirrus trailed cultivator drill

With the RoTeC pro single disc coulter, the Cirrus shows its strength especially on sticky soils, no matter whether early or late in the year. Thanks to the depth guidance directly on the sowing disc, the coulter depth guidance and the reconsolidation via the harrow are completely decoupled from each other. The depth control elements also ensure excellent self-cleaning of the coulter. Thanks to these two benefits, a very flexible and precise operation in virtually all weather conditions is possible. Row spacings of 12.5 and 16.6 cm can be chosen.

Quality and reliability throughout:

• coulter discs made from high grade Boron steel for an even extended service life
• Wear-resistant and self-cleaning Control 10 depth guidance disc and Control 25 depth guidance roller
  for precise control of the placement depth 
• Decoupling coulter guidance and reconsolidation for a smoother coulter run and a universal response to the weather conditions

1. Exact adjustment in 4 steps
2. Reinforced support arm with a coulter pressure of up to 55 kg / hydraulic coulter pressure setting
3. Control 10 depth guidance disc or Control 25 depth guidance roller for consistent sowing depth control. The depth control element actively cleans the sowing disc during use
4. Furrow former for a clean profile seed furrow
5. Sowing disc ∅ 400 mm, made of boron steel, working angle of 4° for smooth operation of the coulter
6. Exact harrow for excellent seed coverage

The sowing disc is made from highly wear-resistant Boron steel and features a diameter of 400 mm. Thanks to the robust design, the wear is reduced to a minimum. Due to the large diameter of the sowing disc, the coulter runs very smoothly resulting in an excellent placement accuracy of the coulter system.

The coulter pressure is infinitely variable with the adjustment being carried out hydraulically from the tractor cab and this serves to maintain an easy matching of the sowing depth and allows the quick adaptation to the prevailing soil conditions. RoTeC pro coulters operate with a coulter pressure of up to 55 kg.

1. Harrow pressure 100 %
2. Coulter pressure 100%

With the aid of the furrow former, the seed furrow is kept clear of any trash ensuring an optimum soil contact for the seed. Due to its flexible mounting, the furrow former rids itself of earth and trapped harvest residues.

One of the unbeatable advantages of the RoTeC pro single disc coulter is that the reconsolidation is decoupled from the coulter depth control. This means that the coulter is raised only once when passing a stone. Furthermore, the coulter pressure and roller pressure can be adjusted independently of each other. This very even and accurately controlled way of guiding the RoTeC pro single disc coulter is ensured by the Control 10 depth guidance disc, with its 10 mm wide disc, or the Control 25 depth guidance roller, with its 25 mm wide roller, mounted directly on the coulter. The basic setting of the sowing depth is in 4 steps and is done directly on the coulter without tools.

Smooth running, rugged and maintenance free

Using the high output TwinTeC plus coulter, AMAZONE equips the Cirrus with one of the most robust and most precise double disc coulters around. Thanks to its coulter pressure of up to 100 kg and its good cutting performance, the TwinTeC plus double disc coulter also manages very well in hard and cloddy seedbed conditions. The coulter body and bearing shell, both made of forged steel, are over-engineered to withstand even under the toughest of operating conditions. Due to the high coulter pressure of the TwinTeC plus double disc coulter, the placement is very precise, even when mulch sowing and with a very high proportion of organic matter in the seedbed. Thanks to the innovative coulter pressure adjustment via an oil circuit, the coulter pressure is maintained even in very hilly terrain so that the pre-set sowing depth is safely maintained. The TwinTeC plus double disc coulter is completely maintenance-free and therefore fulfils the highest demands.

TwinTeC plus double disc coulter (cross-section)

1. Internal scrapers
2. Hydraulic coulter pressure setting from 0 to 100 kg
3. Exchangeable seed guidance
4. Maintenance-free bearings, no lubrication points on maintenance-free coulter
5. Double disc ∅ 380 mm, angle of 10 degrees
6. Guide extension
7. Seed catcher
8. Coulter harrow with adjustable angle
9. Wheel carrier with Control⁺ depth control roller in widths of 50, 65 or 75 mm

The sharp pre-tensioned discs, with a 10° angle of attack ensure a good opening performance of the coulter. The large 380 mm diameter discs ensure a smooth run. Thanks to the large coulter clearance of 190 mm and the connection to the depth guidance roller via the top-mounted coulter carrier, sufficient space remains, so that blockage-free operation is possible. 

The guide extension and the seed catcher safely deliver the seed to the bottom of the furrow and prevent any bouncing out of the individual grains. The standard inner scraper, as an option also with hard metal wear plates, ensures the accurate operation even on sticky soils and noticeably increases the operational reliability.

The parallel-guided depth control roller provides reliable maintenance of the placement depth of each individual coulter. The Control⁺ depth control rollers are available in widths of 50 mm, 65 mm and 75 mm. This means that the performance of the machine is ensured on any soils from the lightest sand with poor carrying ability to the heaviest clay. Optional scrapers on the depth guidance roller ensure a consistent depth of the coulter, even under moist conditions.

Setting the coulter pressure via the ISOBUS terminal is standard. The coulter reliably maintains the pressure selected. This is of special benefit when sowing shallow in very hilly terrain.

 

The same placement depth across all soil types

Apart from application maps for sowing and fertilisation, the coulter pressure on the Cirrus can also be adjusted via application maps.

Arable soils may be highly heterogeneous even on an area of just a few square metres. AMAZONE offers the option of automatic coulter pressure adjustment, in order to adapt to these varying conditions in the best way possible and create the best growing conditions for the plants. The prerequisite for this is the TwinTeC plus coulter.

In addition to the seed and fertiliser maps, a soil map can be created in the farm management system which can be loaded into the ISOBUS terminal in a very short time. The coulter pressure is automatically adjusted to the various soil zones in the soil map while the machine is in use in the field.

Up to 4 different application maps can be run at the same time with the AMAZONE AmaTron 4 ISOBUS terminal. Apart from the soil maps, work can therefore also be carried out with several sowing and fertiliser maps without any problems.

The automatic coulter pressure regulation not only provides the optimum sowing depth at all times, it also makes the work much easier for the driver. This is a great help, especially during night shifts or for operating personnel who normally carry out other tasks, and ensures a consistent quality of work.

After the seed row has been closed by the HD Roller harrow, the soil above the seed furrow is additionally pressed resulting in optimum germination conditions. This is recommended especially for light, dry soils when sowing spring crops or rape. The result is an undulating surface profile that reduces erosion. Thanks to the hardening process of the harrow tines, these offer a particularly high longevity. This means that the special advantage is that the pressure per roller can be set between 0 and 35 kg per roller, completely independently of the coulter pressure.

The optionally available coulter harrow provides additional loose soil above the furrow. This is especially helpful on heavy soils in sloping terrain to prevent capping and the formation of water run-off channels. In addition, any prevailing straw is distributed. The length of the harrow can be adjusted up to seven times as the tine wears. In cases where the harrow is not required, then it can be swung up into its parking position.

The Exact S following harrow works blockage-free, even with large amounts of straw. Individual, pivoting harrow elements allow it to adapt to uneven ground and achieve an even seed coverage. The Exact harrow is particularly useful when sowing under less than optimal conditions, e.g. on moist or heavy ground. The Exact harrow, with 15 mm thick tines, is particularly wear-resistant and ensures reliable seed coverage even under the most difficult of operating conditions.

The harrow pressure is adjusted mechanically by pre-tensioning the harrow springs. When equipped with hydraulic harrow pressure adjustment, a minimum and maximum value is predefined by inserting pins. As a result, the harrow pressure and the coulter pressure can be simultaneously matched to changing soil types via just one tractor spool valve whilst on the move.
