The TORNADO-7000 heavy disc harrow
Heavy disc harrow "TORNADO-7000" is designed to work in fields with a large amount of crop residues, cultivate fallow lands (virgin lands), as well as embedding green manures in the soil to improve its structure, enrichment with nitrogen and suppress the growth of weeds.
The unit is designed for use in various soil and climatic zones, except for the zone of mountain agriculture, when treating soils of different mechanical composition with the moisture content of up to 27% and the hardness of up to 3.5 MPa (35 kg/cm2), not clogged with stones, flagstones and other obstacles.
Sound PRO! arguments for the heavy disc harrows “TORNADO-7000”:
Frame of HDH “TORNADO-7000»:
● The reinforced heavy-weight frame, rigid in all directions of application of traction forces, makes it easy to transfer the load in extreme agro-climatic conditions;
● The frame design adopts thick-walled profile pipes made of 09G2S steel, which is distinguished by excellent weldability and increased strength;
● There are 4 hydraulic cylinders used to fold the frame into the transport position, which makes it possible to extend the service life of each of them and the frame of the entire unit;
● The depth is adjusted using limiters (clips) on the rods of the hydraulic cylinders;
● The stabilizer, located on the unit frame, unloads the frame and ensures accurate copying of the soil relief;
● The hitch with hydraulic adjustment and a height-adjustable cast shackle allows you to operate the unit with different types of tractors of domestic and foreign production;
Working bodies of HDH “TORNADO-7000»:
● The disks of the HDH “TORNADO-7000” with a diameter of 660 mm are made of 65G steel and allow cultivating the soil up to 16 cm at a high speed of up to 12 km/h;
● The disc sections with an X-shaped arrangement allow to treat different types of soil, performing various agronomic tasks;
● Each disc section of the HDH “TORNADO-7000” is installed on two serviced bearing assemblies of our own production with FKL bearings (Serbia), which increases the operational characteristics of these assemblies;
● The disc sections are fixed to the frame with C-shaped racks, which remove shock loads from the bearing assemblies and the frame itself, protecting the entire unit from breakage;
● The adjustment of the angles of attack of the disc sections allows to change the angle from 12 to 21 degrees with a pitch of 3 degrees and this, in turn, expands the range of application of the unit for solving various agronomic tasks.
