The harrow is intended for continuous and pre-sowing soil processing of various mechanical composition for technical, grain and fodder crops and with grinding and embedding of plant residues in the soil (refreshing of sodden meadows) in various agrotechnical schemes. The adjustable processing depth is approximately 8 to 18 cm.
The harrow contains two rows of disks, each of which is located on an individual stand, which is attached to the bar with two L-shaped brackets (diameter 20 mm). This design excludes clogging of the interdisk space. The harrow can be used in all soil and climatic zones where the soil moisture does not exceed 27 percent and the soil hardness does not exceed 3.5 MPa, and it is also not recommended to use this harrow in areas with significant stony inclusions. Due to the use of individual racks in the design, the front harrow can be used at high working speeds - up to 14 km/h.(//tractor-service.com)
This harrow uses camomile discs (cut-out spherical) with a diameter O of 650 mm, a thickness of 6 mm, made of steel grade 65G.
During manufacture, the discs are thermally treated, which ensures a hardness of 38-46 HRC.
Disks are installed on hubs that rotate around an axis on roller bearing units at an angle of attack of 21 degrees and a vertical inclination of 21 degrees.
