Cirrus Grand trailed cultivator drill

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 sowing performance is very precise even under mulch sowing conditions with a 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 coulter pressure can also be adjusted in specific areas by the use of an application map.

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 sharpened, pre-tensioned discs, with a 10° angle of attack ensure a good cutting action 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 with hard metal wear plates ensures 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 guidance 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 for the depth guidance rollers 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.
