Rotary harrow BR-6

Rotary Hoe for Tractor (Rigid Frame 6 meters)

The rotary hoe BR-6 is a high-performance 6-meter implement for continuous crop tillage, designed as an optimal solution for medium-sized farms. This model combines a large working width with the simplest and most reliable design, allowing efficient cultivation of significant areas with minimal investment. The main agrotechnical tasks of this implement are:

• Soil aeration
  Effective crumbling of the upper compacted layer, restoring gas exchange in the soil and opening free access of air to the roots, activating crop growth.
• Weed control
  Effective elimination of 95-100% of weed seedlings at the "white thread" stage, which significantly reduces herbicide treatment costs.
• Moisture conservation
  Effective "moisture sealing" by destroying the soil capillary system, preventing its intensive evaporation and drying out of the sowing layer.
• Work on winter crops
  Effective destruction of the continuous ice crust, saving winter crops from damping-off and restoring their normal respiration after winter.

Unlike classic tine harrows, the BR-6 is equipped with working organs with unique tooth geometry operating on the "micro-explosion" principle. This guarantees high-quality loosening of the top layer without harm to crops - crop plant losses are less than 1% provided timely operations. Structurally, the BR-6 is based on a solid reinforced frame made of profile pipe 140x140x8 mm (steel 09G2S), ensuring exceptional rigidity and durability. The implement is designed to work with the most common tractors of class 1.4 (MTZ-82, MTZ-892), making it accessible for most farms. To solve logistics issues, the harrow is equipped with a special device allowing manual conversion to a longitudinal position for convenient transportation.

Mechanics of action of the unique rotary disc produced by Zavod Moroza on the soil

At the heart of the BR-6, as well as our other models, lies an innovative principle of interaction between working organs and the soil. The key element is a cast tooth of special geometry (spoon-shaped). Its kinematics is designed so that when entering the ground, it works like a needle, and when exiting, it performs a soil tear-out, creating a "micro-explosion" effect. This provides a comprehensive agrotechnical impact:

1. Natural nitrogen fixation through aeration
Breaking the crust opens free access of atmospheric air deep into the sowing layer. Soil oxygen saturation becomes a catalyst for activating beneficial microflora (aerobic bacteria) - these microorganisms begin to intensively mineralize crop residues, transforming them into organic nitrogen and other nutrients that become easily accessible to the plant root system. This acts as a powerful natural growth stimulant.

2. Water balance control (mulching)
The compacted upper soil layer is permeated with capillaries through which moisture intensively evaporates into the atmosphere. The rotary hoe destroys this structure, forming a loose mulching layer 2-3 cm thick on the surface. This barrier blocks the rise of moisture and conserves winter water reserves directly in the root zone, providing plants with moisture even in the absence of precipitation.

3. Mechanical weeding (without herbicides)
Thanks to the high rotation speed of the discs, the teeth effectively tear out weed seedlings at their most vulnerable stage - the "white thread". The weak root system of the weed cannot withstand the jerk, and it soon dies on the surface, while cultivated plants (corn, sunflower, soybean) already have strong rooting and let the working organs pass between the leaves without damage, which allows significant savings on future chemical treatment.

Design advantages of the rotary hoe BR-6

The design of this rotary hoe model is based on proven engineering solutions and the use of specialized steel grades, ensuring stable operation on large areas without breakdowns.

• Load-bearing frame beam: Profile pipe 140x140x8 mm (Steel 09G2S)
• Working organ (tooth): Specially processed (forged/stamped) Steel 45
• Frame connecting plates: Sheet 16-20 mm (plasma cut)
• Fasteners: High-strength bolts (strength class 10.9)
• Bearing unit: Closed, maintenance-free (analogue 53032RS/33003, Bulgaria)
• Operator protection: Special protective screen (mesh) on the frame to protect the cab from flying clods and stones
• Working organ suspension: Individual spring-loaded with the possibility of stepped adjustment of ground pressure

The use of low-alloy structural steel 09G2S and thick-walled pipe 8 mm ensures exceptional rigidity of the 6-meter structure and resistance to torsion. The working teeth, made by forging, effectively resist abrasive wear, and the use of plasma cutting of sheet 16-20 mm for connecting plates guarantees geometric accuracy and strength of welded seams. The model is equipped with a universal hitch, allowing both 3-point mounting and retrofitting with an auto-hitch system.

Economic efficiency compared to old technologies

Replacing outdated hitches with tine harrows with the rotary hoe BR-6 is a step towards significantly increasing the profitability of growing row crops.

• Minimization of crop losses
  The main disadvantage of Soviet harrows is plant injury at the level of 10-15% due to rough mechanical impact. Thanks to the rotary principle of operation, the BR-6 reduces these damages to a statistical error (0.8-1%), maintaining the planned sowing density.
• Speed and fuel
  A rotary harrow requires a high operating speed (up to 15-20 km/h) to create the "micro-explosion" effect - this allows processing the same area twice as fast as classic implements, saving fuel and precious spring time.
• Versatility
  Unlike the BZSS, which is effective only on soil, a rotary harrow allows working on vegetating plants (corn, sunflower, soybean) in phases when chemical treatment is not yet possible or undesirable.

Implementation of rotary harrowing technology allows eliminating hidden farm losses associated with mechanical damage to plants by old machinery. The estimated preservation of 9–14% of the crop on an area of 100 hectares fully covers the capital costs of purchasing a new unit in one season. This approach ensures maximum profitability of each hectare due to the absence of losses in crop stand density during mechanical care.

Tractor requirements and logistics features of the BR-6 rotary harrow

Thanks to the optimized weight and correct geometry of the working organs, the rotary hoe BR-6 does not require super-powerful equipment and works confidently with the most mass-produced tractors of class 1.4 (MTZ-82, MTZ-892 with a power from 80 hp). This allows farms to obtain high productivity at a speed of 15–20 km/h without involving heavy tractors. Since the 6-meter solid frame is oversized, the unit is equipped with a long-distance transport device - for relocation, the harrow is converted to a longitudinal position and towed as a trailer, allowing safe movement along narrow field roads and forest belts.

Advantages of buying a rotary hoe BR-6 at Zavod Moroza

We ensure a full production cycle of units, controlling every stage - from plasma metal cutting to final assembly. At the factory's own foundry, ultra-strong steel bearing housings are manufactured, eliminating the fragility problem typical of cast iron analogues. The harrow's working organs are made by hot forging from steel 45 followed by thermal hardening, ensuring maximum resource even on stony soils. Additionally, we guarantee the constant availability of consumables at the factory warehouse.
