Cirrus trailed cultivator drill

• Reconsolidation in strips using the Matrix tyres
• Cost-efficient AS-tyre as an alternative

At the heart of the machine, and the guarantee of a uniform, quick field emergence, are the Matrix tyres. With dimensions of 400/55R17.5, these tyres feature a diameter of 880 mm and a width of 410 mm (wide enough for 4 seed rows at 12.5 cm spacing or 3 seed rows at 16.6 cm). 

The combination of the big diameter, together with the profile, provides an easy rolling effect – and thus a reduced pulling power. This is a characteristic which is, above all, very important for trailed seed drills that are equipped with passive soil tillage tools and driven at fast forward speeds.

Optimum and uniform growth conditions for all plants are the basis for a quicker and more even field emergence. 

These are obtained by means of a fine crumbed seedbed reconsolidated in strips. Apart from the use of the various pre-working tools, the Matrix tyre is of great importance in this respect. On the one hand, it produces even more fine soil to cover the seed, but, most importantly, its special shape provides the desired reconsolidation in strips.

Advantages of a seedbed reconsolidated in strips 

• Uniform growth conditions for all plants 
• The seed has access to the capillary soil water  
• Prevention of constantly wet conditions after heavy rainfall 
• Guaranteed gaseous exchange

All the above advantages of reconsolidation in strips provide an even, high field emergence!

Reconsolidation in strips 

• Matrix tyres create a well reconsolidated strip in comparison to tyres with an AS profile. This is a key advantage, which has a very positive effect on the smooth running of the sowing coulters.

1. Row spacing 12.5 cm
2. (Plants at a row spacing of 12.5 cm)
3. Row spacing 12.5 cm
4. (Plants at a row spacing of 16.6 cm)

Due to the reconsolidation in strips, it is possible to create optimum soil conditions which match to the current weather conditions and thus ensures the precondition for quick and even plant growth. In addition, the homogeneous and well reconsolidated strip has no cleat marks. This is a decisive advantage compared to rollers with full-surface profiles, as this has an effect on the smooth running of the sowing coulters in particular.

1. Row spacing 12.5 cm (Plants at a row spacing of 12.5 cm)
2. Row spacing 12.5 cm (Plants at a row spacing of 16.6 cm)

As an alternative for regions which are less sensitive to germination conditions, the Cirrus can also be equipped with a simple AS cross-ply tyre of a similar dimension (15.0/55-17). The self-driving effect from its short cleats is very good and thus the machine is also easy to pull. However, this compromises the targeted reconsolidation: the AS tyres do not create the same seed/soil contact compared with the Matrix tyres, especially in dry years.

2. Self-driving effect

Advantages of the AS cross-ply tyre:

• Powerful, smooth self-driving effect
• Cost-effective alternative

1. In severe drought – principle of a water pump:
The re-consolidated strips provide soil contact directly in the seed furrow. In this way, capillary water reaches the seedling even in dry weather. Reconsolidation in strips ensures that your soil works as a water pump. Every drop counts!

2. In much wetness – principle of drainage:
The loose soil absorbs any rain well and stores it. Rain from heavy downpours simply drains into the unrolled, loose areas. Soil erosion is thereby prevented. In this case, the soil works like a drain. Even on heavy wet ground, there is enough unconsolidated soil available between the rows to cover the seed with loose soil.

3. Gaseous exchange – the lungs principle:
The loose soil also enables gases to be exchanged, so that the roots can breathe.
