Harrow rotary hoe 4 meter Grand Max Terra

  Rotary harrow, motiga "Grand Max Terra" (Grand Max Tera)

Rotary harrow "Grand Max Terra" - is designed for pre-emergence and post-emergence harrowing, continuous and inter-row cultivation of crops of any agricultural field crops (grain, tilled, technical), on any type of soil, incl. under difficult conditions (thick and strong soil crust, a large amount of plant residues, stubble treatments, etc.)

When processed during vegetation, it can significantly influence the accelerated and full development of cultivated plants.

The working bodies of "Grand Max Terra" (Grand Max Tera) create an ideal background for the initial development of the root system of plants, well mulch the topsoil, destroying the soil crust, thereby retaining moisture, destroy the thread-like roots of weeds up to 100% at speeds up to 20 km /hour. This makes it possible to switch to herbicide-free technology. With the appearance of a monolithic soil crust on early shoots of cultivated plants, for example, corn at the stage of 2-3 leaves, when the use of tine harrows is impossible, the efficiency of using "Grand Max Terra" (Grand Max Tera) increases dramatically.

Soil loosening (destroys capillaries and increases its porosity), harrow technology :

• Surface fluffing and aeration of the soil - microexplosion;
• Destruction of filamentous shoots of weeds;
• Promotes even distribution of moisture;
• Promotes uniform distribution of oxygen;
• Helps strengthen the plant and accelerate growth
• Promotes an even distribution of terrain

At the world level, it has been proven that one pass of the hoe harrow delivers 100 kg of nitrogen per 1 ha to the soil:

• For corn, 20-25 centners - nitrogen fertilizers 100%
• For winter wheat by 10-15% - potash fertilizers 100%
• For sunflower at 4-5c - phosphate fertilizers up to 100%, fuels and lubricants up to 40%

Analysis and conclusion based on the results of tests and data of scientists, the impact of a micro explosion on the soil (in addition to loosening) contributes to a sharp displacement of carbon dioxide accumulated there from the upper soil layer and its replacement with oxygen and nitrogen from the air, which significantly activates (accelerates) soil biological processes and accumulation ( synthesis) of nitrogen and thereby leads to a sharp and full development of cultivated plants (one pass of a rotary harrow is commensurate with the introduction of nitrate into the soil in an amount of 100 kg / ha).

Target:

• microexplosion - soil aeration surface loosening;
• correct destruction of filamentous weed shoots;
• distribution of moisture and landscape, strengthening of plants;
• obtaining full seedlings.

The rotary harrow "Grand Max Terra" (Grand Max Tera) fully meets the high requirements of modern agricultural enterprises. The harrow has a long service life and is suitable for both traditional and conservation tillage. The harrow is well suited for both continuous and inter-row cultivation, it allows you to cultivate the soil even with a grown plant. The harrow works from 2 leaves up to 20 cm plant height. If you increase the row spacing, you can work up to a height of 60 cm.

The process of the harrow passing through the field:

• The teeth of the harrow enter at a right angle to a depth of 3-5 cm, while destroying 70-90% of the filamentous weed at the development stage;
• Crops are not damaged at all (10% loss)

Advantages of our harrow:

• The working body of the harrow is a fixed, forged blade. Each blade is made at an angle vertically and this makes it possible to completely pull out the filamentous germinated weed, improving the air and temperature conditions in the soil, to the depth of seed planting.
• Blades forged from steel 65G, 8mm thick. Hardened and tempered in oil in compliance with the temperature regime, which gives the blades high wear resistance, metal resistance to hitting cobblestones.
• The shape of the spatula is pike-shaped, made in the form of a spoon similar to the John Deere technology;
• On the working body of the harrow there are two "Suns" made using hot air hammer riveting. The distance between the "suns" is 100mm.
• It has a high frame, which allows for inter-row processing at a later stage of the growing season;
• In the hubs, 2 bearings, double-row closed type;
• Salentblocks from Lada Priora Zhiguli (works better and softer);
• The axles are made of steel 40X;
• Beam 140x140, wall 8mm;
• Bolts strength 8.8;
• Bronze bushings;
• Weight 120 kg;

Specifications:

• Productivity, up to - 100 ha/shift;
• Working sections - 19 pcs.
• The number of blades per wheel - 16 pcs;
• Aggregated with class tractors - 1.4-2.0
• Service staff - 1 person.

  Timely harrowing during the growing season makes it possible to obtain full shoots.

Spring harrowing of crops using a rotary harrow "Grand Max Terra" (Grand Max Tera) , has a much more effective effect on the acceleration and development of cultivated plants due to the additional input of nitrogen into the soil. In spring, the soil is harrowed to close the moisture. At the same time, the surface of the arable land is leveled, as a result of which less moisture evaporates from it. This means that the compacted upper layer is destroyed, the capillaries between the water-rich lower layer and the upper layer are interrupted. The loose soil layer is better warmed up and ventilated, microbiological processes are actively taking place in it, nutrients are rather accumulating. The use of "Grand Max Terra" technology (Grand Max Tera) gives you increased yields and significant savings
