Cirrus Grand trailed cultivator drill

As standard, the Cirrus-C is equipped with a 2-stagger 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 element can be adjusted on the move. Via a series of holes, the end discs can be adjusted individually to ensure a level finish between bouts.

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 sprung rubber blocks and which optimally follows the ground contours. In addition, the rubber sprung buffers act as an overload safety device 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.
