Rotary harrow BR-3, Zaporizhia region.

Rotary harrow BR-3
— Destruction of the surface crust of the soil with a depth of 2 to 10 cm.
- Width of capture - 3 m.
— 23 working bodies.
— The working wheel of the section uses a high-quality maintenance-free bearing manufactured in Bulgaria.
— The working body (section tooth) is made of 45L steel (this steel grade is used for parts that require increased strength and high wear resistance and work under static and dynamic loads).
— Reduced fuel consumption thanks to the correctly calculated shape of the teeth of the workingwheel harrow and their number.

Rotary harrow BR-3 is designed for full and inter-row cultivation of soil on which all types of crops grow: cereals, legumes, cereals, etc. in the pre-dawn and post-dawn period with the aim of:

– Destruction of the ice crust.
– Pre-sowing soil preparation.
– Destruction of the surface crust on the soil with a depth of 2 to 10 cm, as well as its high-quality mulching.
– Destruction of weeds at the stage of thread-like ladders.
- Loosening the soil and saturating it with moisture and air (the principle of aeration using micro-explosion technology to saturate the soil with nitrogen).

Thanks to the correctly calculated shape of the teeth of the workingharrow wheel and their number, the maximum loosening of the soil layer is achieved. This allows to reduce the resistance of the unit, which in turn reduces fuel consumption per hectare.

A feature of this BR-3 rotary harrow is the possibility of harrowing both before and after emergence. The harrow processes even the heaviest soils with a thick crust and a lot of weeds. Its frame is made of a solid tube, which increases the strength of the structure by 4 times. The working bodies are made of stamped steel of class 45L, which has high wear resistance and excellent properties, which is relevant in the fight against weeds.

When the tractor starts moving, the hoe wheels also begin to rotate, while their teeth sink into the soil to a depth of 2-7 cm, destroying the surface crust. Thanks to the special design of the tooth, when it leaves the ground, a micro-explosion occurs, thanks to which air is pumped into the soil. Nitrogen contained in the air enters the soil and is absorbed by plants, which contributes to their development. This technology makes it possible to do without nitrogen fertilizers and switch to ecologically clean cultivation without herbicides.(//tractor-service.com)
In addition, this type of harrowing creates an excellent background for the primary development of the root and other plant systems, mulches the surface layer of the earth and destroys the soil crust, while preserving moisture.
An important aspect when using the rotary harrow BR-6 is the fact that damage to cultivated plants from its use is no more than 0.8-1%. For example, the loss from the use of other types of harrows is at least 10-15%. It is worth noting that when using a rotary harrow-hoe, 95% to 100% of weeds are destroyed at the thread stage. It is also important that this type of technique is used at those stages of plant growth (corn 2-3 leaves), when it is impossible to use tooth harrows, which allows to achieve an additional positive effect.

The design of the BR-6 rotary harrow is collapsible, therefore, if necessary, it is possible to change its individual elements. Unlike cultivators, a trail harrow, a rotary harrow is not afraid of wet soil - it will not stick to anything and become clogged.

The speed of the device when cultivating the soil is 15-25 km/h, and the width of capture and the depth of soil cultivation are 3 m and 2-10 cm, respectively. The high frame ensures high-quality tillage at the later stages of plant growth.

The operation of the BR-3 rotary harrow has a positive effect on planted crops:

- uniform saturation of the soil with oxygen and moisture;
- strengthening and accelerating the growth of plants.

Advantages

– a wide range of performed works;
– high speed;
- a large grip of cultivated soil;
- durability and reliability in operation thanks to the use of wear-resistant materials.

The use of a BR-3 rotary harrow creates ideal conditions for plant growth and the passage of other agricultural machinery across the field.https://zavodmoroza.com
