Cirrus Grand trailed cultivator drill

The T-Pack tyre packer ensures a capillary water connection by pressing loose soil evenly and consistently across the entire working width. This ensures that the implement runs even more smoothly and increases its load-bearing capacity on deeply loosened ground but only moderately reconsolidates the soil.

The Crushboard on the Cirrus ensures more effective seedbed preparation by reliably breaking up coarse clods and creating a fine crumbly soil structure. This ensures that the seedbed is perfectly levelled, promoting even seed placement and conditions conducive to good emergence. The working depth can be adjusted hydraulically to suit the ground conditions. Combining several work steps in a single pass reduces the amount of work required, thereby saving time and fuel.

The advantages of the Crushboard:

• Evening out the ground and breaking up any clods
• Levelling effect after ploughing or rough preparatory work
• Implement runs more smoothly in the field
• Improved sowing, especially in wet conditions
• Hydraulic working depth adjustment for flexible adaptation
• If necessary, the Crushboard can be swung out in work

As standard, the Cirrus-C is equipped with a 2-row disc element for seedbed preparation. The discs have a diameter of 460 mm. This is ideal for creating a fine crumbed structure in the soil and incorporating organic material.

The working depth of the disc unit can be adjusted on the move from the tractor cab. Manual disc adjustment options via a series of holes ensure a clean transition at the edges from pass to pass and a level seedbed in the tractor wheel track area.

Two options are available for the disc element: a fine-serrated disc or a coarse-serrated disc. A steep angle of attack for the discs ensures a particularly intense mixing. 

Fine-serrated disc 
The fine-serrated disc shows its strength more in shallow seedbed preparation. It provides more fine soil for good seed embedding. 

Coarse-serrated disc 
The coarse-serrated disc provides a more intensive soil movement. Due to its profile, extremely effective incorporation, including the mulching of harvest residues, is achieved. 

The disc system combines two discs mounted on one arm which is suspended via rubber sprung blocks and which optimally follow the ground contours. In addition, the rubber sprung buffers act as an overload safety protection on stony soils. This means that the operational reliability is increased and turn-round times are reduced. The heavy clamping setup ensures a consistent working depth.

Enhanced technology for even field emergence

The Matrix tyres ensure an even and high field emergence. With dimensions of 400/55R17.5, these tyres have a diameter of 860 mm with a width of 400 mm. 

The high diameter combined with a special tread generates a higher self-driving effect in comparison to machines with an AS profile.

Furthermore, the independent suspension enables the machine to be pulled around curves and manoeuvred in field corners with minimal effort. This low-stress turning process protects the machine from excessive 

load and wear. Furthermore, the soil is prevented from being bulldozed and pushed up when working around bends. Consistent seedbed quality and maximum soil structure protection are ensured.

Road transport is fast and safe

The Matrix profile tyres not only produce an optimum seedbed, but also serve as transport wheels. The Cirrus is characterised by a high stability on the road, even at a transport speed of 40 km/h. This is possible because the machine only runs on 4 wheels of the tyre packer. The high carrying capacity of the wheels allows the middle pair of wheels to be lifted up (between the 4 transport wheels).

Reconsolidation in strips – for optimal growth conditions

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 profile tyre 
is extremely important in this respect. On the one hand, it produces even more fine soil to cover the seed, but, most importantly, its special profile 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!

1) In very dry conditions – the water pump principle:
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 very wet conditions – the drainage principle: 
Loose soil easily absorbs any rain and stores it. Rain from heavy downpours simply soaks 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.

Reconsolidation in strips 

• Matrix profile tyres create evenly reconsolidated strips 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.
