An ideal seedbed is important for achieving maximum plant growth. The cultivated soil should be perfectly level and work properly across the working depth and machine width. The most important is the seedbed, where the seeds are planted.

It needs to be entirely reconnected for the best water supply. The optimal seedbed structure comprises fine soil in the seed zone and more soil on the surface, achieved through excellent field formation. The "Karer Model" is essential for producing such ideal seedbeds.
