Grubber

The grubber (also called cultivator), by definition, is a machine or tool for eradicating weeds or old crops from the ground.
In agronomy, the grubber is an agricultural tool equipped with anchors, which is normally used after plowing for a rough preparation of the seed bed, and a consequent leveling of the field.
With the advent of the technique of minimum tillage or minimum tillage, however, the grubber can replace traditional plowing.
From a mechanical point of view, a grubber is a tool equipped with anchors arranged in parallel rows that allow, with the passage of the tool, the turning of the clods and a partial burying of the branches present on the surface.

Furthermore, if this tool is combined with rear rollers, generally with a cage or spikes, it is possible, with a single passage, even a fair leveling of the ground.
On the agricultural machinery market there are different types of grubbers depending on the work power required and for some technical aspects such as the type of anchors, the safety systems of the anchors or springs, the number of rows of anchors and the working depth. Instead of anchors, some models have curved-shaped elastic teeth; this type of tool, called the light cultivator, works at a lower depth, but favors the shredding and mixing of the soil.
A similar function of the grubber is carried out by the disc harrow, while when deeper work must be carried out instead of the grubber, the subsoiler and the scarifier are used.
