Production and sale of rotary harrows, Dnepropetrovsk region.

Production and sale of harrows rotary hoes at optimal prices with free delivery to farms in Ukraine.
The width of harrows of rotary hoes is 3, 6, 9 and 12 meters.
The 6-meter harrow of the hoe has both a solid frame and a hydraulic one.
9 and 12 meter rotary harrows and hoes are fully hydrated.
The harrow section consists of a rack, a pendulum mechanism and two working wheels. 16 working fingers are mounted on the working wheel under the rivet tool. Two roller conical bearings 30204 are installed in the serviceable hubwheels.
Purpose of Harrow rotary hoes: pre-emergence and post-emergence harrowing of field crops (cereal, fallow, technical) with the purpose of surface loosening and aeration of the soil, saturation of the soil with oxygen (nitrogen), destruction of filamentous weed seedlings. Steam processing, application of fertilizers and herbicides.

Principleработы Rotary hoe harrows : When the tractor is moving in the corral, the workerswheels begin to rotate spontaneously (according to the type of disc tools ), are buried in the soil, to a depth of 3-5 cm, due to which the surface crust is destroyed. At the exit of the wheel beam from the ground, a micro-explosion occurs, thanks to which air is injected into the soil. As a result, the nitrogen contained in the air passes into the fertile layer of the soil and is absorbed by plants. This makes it possible to refuse the introduction of nitrogen fertilizers. The working organs of the hoe create an ideal background for the initial development of the root system of plants, the upper layer of the soil is well mulched, the soil crust is destroyed, thereby preserving moisture. Up to 0.8% of cultivated plants are damaged during BMR operation. For comparison, when processed with tooth harrows of the BZSS type, damage is 10-15%. At the same time, threadlike roots of weeds are destroyed up to one hundred percent at speeds of up to 15 km per hour. Timely use of a harrow allows you to completely abandon herbicides. With the appearance of a monolithic soil crust, on early seedlings of cultivated plants, for example, corn at the stage of 2-3 leaves, the use of tooth harrows becomes impossible, and then the efficiency of using a hoe increases dramatically.
Results of the work of the rotary hoe harrow :
The following data and positive results were obtained as a result of experiments with the direct use of BMR. In the phase of spring tillering, a comparison was made on the percentage accumulation and content of nitrogen, namely in the available form, for winter wheat from the air, in comparison with the plot where ammonium nitrate was applied, at the rate of 20-21 kgd.v./ha or 60 kg/ha. Selection of plants for analysis was carried out on the 15th and 35th days after treatment. The entire aerial part of the plant was analyzed by the Kjeldahl method.

According to the results of the analyses, it is clear that the nitrogen content in winter wheat plants is at the same level of availability. It should also be noted that thanks to BMR, the destruction of annual weeds, in filamentous form, amounted to 85%, the aeration of the soil increased significantly and the dense, surface crust was destroyed. The effect with the use of a hoe was similar on corn crops, the "stilt" stage and in the 3-4 leaf phase, as well as on sunflower crops after sprouting (two false leaves) and in the 2-4 leaf phase. Destruction of weeds, in the thread phase 90%, seedlings 25%, damage to cultivated plants 0.7%.
На посевах кукурузы, стадия «шильце» и в фазе 3-4 листа, а также на посевах подсолнечника по всходам (два ложных листа) и в фазе 2-4 листа, эффект с применением мотыги, был аналогичный. Уничтожение сорняков, в фазе нити90%, проростков25%, повреждение культурных растений0,7%.
The harrow is a rotary hoe for winter wheat (predecessor of sunflower), in the phase of the beginning of tillering and full tillering, sown according to zero technology, it allowed to increase the yield (on experimental fields) by 5.6 t/ha, saving: seeds by 10%, nitrogen fertilization 100%, potassium 100%, phosphoric 75%. Fuel economy was 20%.
