Harrow 18-disc two-section 1.7 m (China), Kyiv region.

Harrow 18-tydisc hinged two-section 1.7 m used for dividing the sodden layers after plowing virgin soils, processing of meadows and pastures, application of fertilizers and harvest residues, effectively fulfills its tasks on slopes, dry and heavy soils. Thanks to the optimal combination of the disc diameter, the number of sections and the width of the grip, the time of soil processing is significantly reduced. The harrow is used in a hitch with tractors with a power of 28-40 hp, it is distinguished by reliability and high productivity.

Two rows of jagged harrow disks enter the soil layers at an angle, which allows to reduce the traction force and improve the stability of the unit. Easily plunging and rotating, the cutting elements produce surface loosening, partial turning of the soil, and trimming of weeds. The ability to adjust the angle of attack of the discs from 0 to 23○ ensures effective work regardless of the conditions and type of soil. The sharp edge of the cutting elements of the harrow contributes to the high-quality grinding of soil layers, and the characteristic cutouts on thedisks prevent the accumulation of plant residues. For better shreddingsoil disks of the rear battery are offset relative to the front disks.(//tractor-service.com)

The necessary depth of processing is set by changing the angle of attack, rearranging the fingers of the hitch and adjusting the pressure of the discs on the soil (due to the weight of the ballast).

The structural shape and arrangement of the discs allows you to bury plant residues more effectively, increase the stability of the harrow during movement, reduce the resistance during contact with the soil, and increase the efficiency. In a trailer with a mini-tractor, such properties of the unit ensure fuel economy and minimal energy costs.
