ADN-2 mounted disc harrow, 5, Dnepropetrovsk region.

Disk harrow mounted ADN-2.5 is designed for processing all types of soil by shuttle method, creates an optimal natural soil structure for plant growth and rolls the top layer of soil to preserve the soil moisture.

Harrowdisc mounted ADN-2.5 combined the functions of a plow,husker, a cultivator and a disc harrow. They ensure uniform distribution of organic fertilizers and post-harvest residues throughout the depth of the treated soil layer, which increases the soil's resistance to erosion processes and increases its ability to absorb moisture.
Design features:
- the construction of the ADN-2.5 frame is strengthened in comparison with units of a similar type (see photo 1);
- the rack of the working body is installed in the frame in a sleeve that protects the seat in the frame from deformations. In addition, at the place of installation of the rack in the frame, a guide is installed to avoid jamming during the change of the angle of attack of the disk;
- the rack of the working body, made of a circle with a diameter of 60 mm. has reliably proven itself in work on clogged and dry soils;
- Quick-release method of removing discs;
- discs made of boron steel;
- adjustment of the angle of attack (3 positions);
- Powder coating.
- the following modernizations were made in the design of the roller-chest roller, which rolls, for more efficient work:
- installed strips of 60x6 mm.;
- Roller mounting brackets reinforced with stiffening ribs;
The plant is sorting out the organization of delivery of equipment to the farm. The equipment comes with a passport with a 12-month warranty.(//tractor-service.com)
All constructive modernizations, aimed at improving the operation of the ADN-2.5 harrow, were carried out on the basis of practical experience, taking into account the recommendations of specialists of partner farms.
