The simple alternative for successful sowing

The TwinTeC special coulter for mounted seed drills means that AMAZONE can offer the ideal coulter for light and medium soils at speeds up to 10 km/h. With a coulter pressure of up to 45 kg/coulter, the coulter travels very smoothly through the soil precisely and reliably placing the seed. 

Benefits of the TwinTeC special coulter

• Reduced lifting force as a result of the lightweight design
• Better handling on the road and in the field as a result of its compact design
• Good soil-seed contact provided by trailing depth guidance roller
• Perfect depth control and simple setting as a result of trailing depth guidance roller
• Cost-sensitive alternative to the TwinTeC double disc coulter
• Simple operation and straightforward maintenance

Easy manual adjustment

In order to ensure that the placement depth of each individual TwinTeC special coulter is maintained, there is the Control 50 depth guidance roller behind each double disc coulter to ensure its precise depth control. The placement depth is easily adjusted on the right and left of the Centaya Special. The placement depth can be infinitely variably adjusted in each case, depending on the position of the depth guidance roller. 

Infinitely variable range of adjustment:
Lower position of depth guidance roller: 1 to 4.5 cm
Upper position of depth guidance roller: 2.5 to 6 cm

Setting the coulter pressure is carried out centrally via a spindle in the middle at the back of the Centaya Special.
