Cultivators - loosening the soil.

Cultivators are used for deeper soil loosening. The depth of their work is 5-15 cm. They are also responsible for breaking the crust on compact soils and destroying weeds, the roots of which are trimmed with the help of duck feet. When using spring tines, the cultivators pull out couch grass roots well on top. After spring plowing, cultivators are only used then, when drags and harrows do not guarantee good soil preparation for sowing or planting, especially deep-rooting plants, e.g. root crops. Cultivators can also be used on stubble - in order to stop water evaporation from the soil, as well as for destroying turf in the field before plowing - to facilitate penetration of the plows. You can also use cultivators to mix mineral fertilizers with the soil. The working parts of the cultivators are springy, semi-rigid or stiff teeth. Spring tines vibrate constantly under the influence of changing soil resistance, which contributes to good crushing and mixing of the soil, but it is not conducive to maintaining the same depth of work. Such tines are particularly suitable for polluted soils, because their vibrations make it easier to shake and bring out couch grass runners to the top.
At the end of each tine there is a goose foot or a double-sharpened share, which, when one end is blunted, can be turned.
The disadvantage of spring tines is this, that on compact soils, they bring out conglomerates to the top, which dry and harden.
Semi-rigid tines can be ended with coulters of various shapes. They maintain the working depth much better and spray the soil less than the spring tines. They are especially suitable for the spring preparation of soil before sowing. Rigid tines are particularly suitable for working on cohesive and cohesive soils.
