Cirrus Grand trailed cultivator drill

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 very good cutting performance, the TwinTeC plus double disc coulter also manages very well in hard and cloddy seedbed conditions. The basic body and the coulter bearing shell made of forged steel are equipped with sufficient reserves, even under the toughest 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 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.

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 cutting 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 rollers provide the safe maintenance of the sowing depth on each individual coulter. The Control⁺ depth control rollers are available in widths of 50 mm, 65 mm and 75 mm. This means that the working 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 the even guidance 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.
