The name ‘grubber’ says a lot about that work that this tool carries out and its form: its features are tine teeth and shear bolts. In the straight ground management, grubbers, which often used to be called cultivators, are used to work organic substances into the ground, to get rid of weeds and to loosen the ground. Grubbers are often used in combination with other agricultural machinery such as harrows to work the seedbed.
The fundamental use of cultivators is to sustainably loosen ground which has been affected by the weather conditions in order to prepare it for other machinery. Furthermore, cultivators help with the incorporation of manure into the ground and also in terms of seed beds they rip open the upper ground layers. In terms of history, cultivators have undergone a development which has ended with them now being mechanical machinery. At first, cutivators were hook-like sticks which were used to loosen the ground. In a limited manner of construction the grubber was used from the middle of the 19th century as a tool which was pulled by animals. The number of tine teeth were, however, limited because of the animals.
The area of work was accordingly small: Cultivators were mainly used for the preparation of seed beds or for easy loosening of the ground in the winter. The change in the construction manner came with the mechanisation of the machine. Different types of cultivators were from that point onwards brought onto the market, including ones with feather tine teeth and teeth which were attached to hydraulic cylinders. With this development in the construction the teeth were no longer just rigidly fixed to the frame. This sort of old construction is only used today on extremely hard ground. A popular area of work for the grubber is potato cultivation. Cultivators are particularly used a great deal in the preparation period. In terms of grubber production, the company Amazone and the Czech company Farmet are well-known.
