Hlubokkhlytel chisel 1, 8 2, 4 2, 7 3, 6 4, 5 under tractor MTZ 80 82 1221, Kievskaya region.

Universal deep looseners process compacted soil of various types to a depth of 30 to 50 cm in order to loosen it.
The operation takes place without overturning the layer and provides grinding with mixing of the upper layer of soil to improve the water-air condition of the root layer, which prevents the development of soil erosion, contributes to the accumulation of moisture and increases the yield of agricultural crops.

Soil treated with a universal deep loosener accumulates more than 300 tons of moisture per hectare. At the same time, it prevents the creation of water saucers in the field and the wetting of agricultural crops.

The working bodies are symmetrically located on the frame!!! This excludes the effect on the attachmenttractor of the moment of forces that arise between the working surfaces of the deep loosening paws of the first and second row with pieces of soil, which ensures better soil processing and excludes twisting of the unit relative to the course during work.

The used working bodies of the "PARAPLAU" type manufactured by "BELLOTA" (Spain) are made of boron steel with heat treatment and have high wear resistance and elasticity, provide vertical and horizontal wave-like movement of the soil with energy savings.

The unit is equipped (at the request of the customer) - either with a support rollerкатком, which performs only the function of regulating the depth of cultivation, or with a tandem-spur roller, which ensures the grinding of plant residues and additional lowering of the top layer of soil to a depth of up to 12 cm.

GRU and GRU ECO have a number of constructive advantages over their counterparts:
1. In theconstruction of the roller double-row bearings are used in a cast support made of high-quality cast iron, which facilitates their maintenance and provides 5 times more!!! resource compared to the UCF-208 bearing.
2. The use of anti-corrosion primer ensures the resistance of the unit parts to aggressive conditions during operation.
3. The frame and hinge of the unit are made of pipes of a larger size compared to analogues and have a one-piece welded construction, which ensures high reliability under long-term loads.
The use of GRU and GRU ECO units has a number of agronomic advantages, namely:
1. Contributes to the accumulation of moisture during the period of precipitation (the universal deep loosener is most effectively used when growing arable crops, as well as in areas with insufficient precipitation and irrigated agriculture).
2. The optimal ratio between the porosity of the capillary system of the soil and atmospheric air exchange is achieved, biological processes in the soil are activated.
3. The water permeability of the soil improves and the accumulation of productive moisture reserves increases, fertility increases.
4. The development of wind and water erosion of the soil is prevented.

The shear bolt, installed in the upper part of the legs, reliably protects the racks and the frame from overloads. After breaking, the bolt can be quickly and conveniently replaced.
