cultivating equipment, with the pre-unit doing the job has to tear up the soil, while the following device crushes the still coarse soil as finely as possible and should press. So-called peeling cultivators are used to peel the soil, for example for leveling the soil Spring-tine harrows and crumbling rollers for chopping and analyzing. For the production of a fine top layer of clay are used for tow bars or the like.

According to the German utility model 7 238 728 is a tillage device became known, which consists of a towed by a tractor, loosening tools carrying Frame and a crumbler roller, which is articulated on the frame by means of arms. With the axis of the Crumbler roller is in turn articulated to a drag rail for fine processing of the soil via retaining arms. The processing device thus consists of a previous device with a maximum of two attached downstream devices. The arrangement of a further device is not possible.

For the purpose of adjusting the height of the crumbling roller, the arms are mounted on bolts which are offset in height Holes of guide rails connected to the frame can be optionally inserted.
