Green Star Optimus 9 m EURO mounted rotary harrow with one-piece tines:

• designed for spring and fall loosening of soil covered with stubble or other plant residues, weed seed incorporation and destruction of crop residues, as well as for leveling of micro-relief created by previous cultivation; for spring harrowing of winter and row crops, pre-sowing tillage on plowed fields and maintenance of perennial grasses;

• works effectively at early stages of plant development;

• breaks monolithic crust on the soil up to 7 cm thick, especially effective for corn and sunflower at the early stages of sprouting (2-3 leaves);

• mulches the top layer and reliably covers the moisture, the degree of moisture retention in the soil is increased threefold; especially effective in regions with arid climate or unstable precipitation;

• saturates the soil with oxygen and nitrogen;

• kills 99% of weeds in the white thread stage;

• damages up to 1% of plants (for comparison - tooth harrow damages 10-15%);

• in case of timely application allows to completely refuse from herbicides;

• does not injure plants up to 15 cm high;

• can be used for inter-row cultivation of plants up to 35 cm high (7-8 leaflets), for which it is necessary to remove the sections of the working tools that interfere with cultivation;

• can be used on continuous crops and perennial grasses.

Advantages and design features of the Green Star Optimus 9 m EURO mounted rotary harrow with one-piece tines:

• internationally certified production;

• 1 person (tractor driver);

• can be coupled with tractors 110 - 150 hp;

• 3 years warranty on hydraulics;

• row spacing can be adjusted from 10 cm;

• the use of rotating sun-shaped discs increases the impact on the soil up to 40%, contributes to the activation of metabolic processes, which corresponds to nitrogen fertilization with mineral fertilizers;

• the frame is made of one-piece seamless pipe 140x140x8 made of 09G2S steel;

• reinforced rack of rotary wheels is made of one-piece pipe 50x50x5 without welded seams from steel 20, warranty on the rack - 12000 Ga;

• friction units use bushings made of special composite material, which do not require maintenance; the material is patented, the author's development of Avers-Agro, warranty on bushings - 15000 Ga;

• bushing on the bracket and rocker (made of special composite material), does not require lubrication and allows to copy the relief of the soil and provides the same depth of cultivation;

• each sprocket is fitted with two sealed, non-maintained bearings from SKF, additionally protected by anthers;

• the warranty on the bearing unit is 2000 ha;

• Green Star harrow tooth is made of quality hardened steel 30ХГСА in contrast to the tooth production by casting;

• the shape of the Green Star rotary harrow tooth is the author's development of Avers-Agro company;

• special tooth geometry, the tooth enters the ground at right angles;

• the design of the implement ensures quick replacement of a tooth or the entire sprocket in the field; replacement teeth are individually fastened with high-strength bolts and self-locking nuts;

• each section is fitted with an adjustable spring with a diameter of 6 to 12 mm, which provides the necessary deepening on all types of soils depending on field conditions;

• availability of sprocket variants of various shapes for different field crops and agronomic tasks.

Additional equipment:

• turbo blades - allow the harrow to be used as a shredder of crop residues (sunflower and corn) in the fall;

• scraper - allows the harrow to remove thread weeds from row crops;

• tanks for loose and liquid fertilizers.
