Disk harrow ADN-2.5 is designed for the main and pre-sowing processing of fields, while creating an optimal natural soil structure for plant growth and rolling the top layer of soil to preserve soil moisture. The disk harrow has two variants: ADN-2.5 mounted and ADP-2.5 trailed. The ADN-2.5/ ADP-2.5 harrow is equipped with disks with a diameter of 660 mm for 10 petals, which are mounted on round racks, with the possibility of changing the angle of the disks.
This is an ADN-2.5 disc harrow that combines the functions of a plow, a
husker, a cultivator and a disc harrow, which ensures uniform distribution of harvest residues throughout the depth of the cultivated soil layer, which increases the soil's resistance to erosion processes and increases its ability to absorb moisture.
Design features of the ADN-2.5 disk harrow :
- the construction of the ADN-2.5 frame is strengthened in comparison with units of a similar type.
- 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 disc;
- the rack of the working body, made of a circle with a diameter of 60 mm. reliably proven itself in work on clogged and dry soils;
- Quick-removal method of removing disks;
- 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 stiffeners;
