جديد المشط القرصي Harrow rotary Green Star 12 m mounted with replaceable teeth Joh

Rotary harrow Green Star 12 m with replaceable teeth John Deere:
The harrow consists of a central section, two folding wings, transport wheels, support wheels and a trailed harrow for transporting roads. The harrow is transferred from the transport to the working position using the hydraulic cylinders mounted on the transport wheels. Depth of processing is regulated by means of the support wheels located on the central section.
designed for spring and autumn loosening of soil covered with stubble or other plant debris, planting weed seeds and destroying crop plants, as well as for leveling the microrelief created by the previous treatment; for spring harrowing of winter and row crops, pre-sowing tillage on plowed fields and care for perennial grasses;
destroys the monolithic crust on the soil, especially effective for corn and sunflower in the early stages of seedlings (2-3 leaves);
mulch the top layer and covers moisture, the degree of moisture retention in the soil increases three times;
saturates the soil with oxygen and nitrogen;
destroys 99% of weeds in the white filament stage;
damages up to 1% of plants (for comparison, the tooth harrow damages 10-15%);
with timely use, completely eliminates herbicides;
does not injure plants up to 15 cm high;
can be used for inter-row processing of plants up to 30 cm high, for which purpose it is necessary to remove the sections of the working bodies that interfere with the processing;
can be used for continuous sowing and perennial grasses.
attendants - 1 person (tractor driver);
it is aggregated with tractors from 80 hp;
the row spacing is adjustable from 10 cm;
the use of rotating sun-shaped disks increases the effect on the soil by 40%, promotes the activation of metabolic processes, which corresponds to nitrogen fertilizing with mineral fertilizers;
the frame is made of seamless seamless pipe 140x140x8 made of steel 09G2S;
the rack of rotary wheels is made of a solid pipe 50x50x5 without welds of steel 20;
friction units use bushings made of special composite material that do not require maintenance; the material is patented, copyrighted by Avers-Agro;
the sleeve on the bracket and rocking chair (from a special composite material does not require lubrication), which allows you to copy the relief of the soil and provides the same depth of processing;
for each sprocket wheel, two sealed non-serviceable bearings from SKF are additionally protected by anthers;
the Green Star harrow tooth is made of 30HGSA quality hardened steel;
the tooth shape of the rotary Green Star harrow is the copyright of Avers-Agro;
special tooth geometry, the tooth enters the ground at a right angle;
the design of the working body provides a quick replacement of the tooth or the entire sprocket in the field. Interchangeable teeth are individually attached with high-strength bolts and self-locking nuts;
a compression spring of different wire sections from 6 to 12 mm is installed on each section, which provides individual adjustment depending on field conditions;
availability of options for stars of various shapes for different field crops and agricultural tasks.
Additional equipment:
turbo-cutters - allow using the harrow for crop residues (sunflower and corn) in the autumn as a chopper;
skrebnitsa - allows you to save the sowing of row crops from the filamentous weed;
tanks for bulk and liquid fertilizers
