Green Way 21 m chain harrow
Green Way 21 m is a trailed chain harrow manufactured by Avers-Agro for seedbed preparation, moisture conservation, field surface levelling, soil crust breaking and even distribution of crop residues.
The harrow has 16 rows of diamond-section tines with 6 attack angle positions, allowing the cultivation intensity to be adjusted to soil conditions and the task. Working width: 21 m; working depth: 2–8 cm; recommended speed: 8–15 km/h; field capacity: up to 25.3 ha/h. A tractor with at least 340 hp is recommended for Green Way 21 m.
Applications of Green Way 21 m
- moisture conservation in early spring;
- seedbed preparation;
- field levelling after disc harrowing or cultivation;
- breaking clods and soil crust;
- even distribution of crop residues;
- levelling tractor wheel tracks;
- removal of weeds at the white-thread stage.
With 1428 tines arranged in 16 rows, the harrow provides full coverage across its working width and successive treatment of the field surface. The diamond-shaped tine cross-section helps reduce draft resistance, while the adjustable attack angle allows Green Way to adapt to different working conditions.

Estimated fuel consumption when operating the Green Way 21 m harrow starts from 4 l/ha. Actual consumption depends on the tractor model, working speed, field conditions, soil type and working depth.
Purpose of the Green Way 21 m chain harrow
The Green Way 21 tine chain harrow is used for shallow cultivation at depths from 20 to 80 mm. Its design allows several operations to be completed in a single pass:
Moisture conservation
Seedbed preparation
Final field levelling after disc harrowing or cultivation
Clod breaking
Mixing and even distribution of crop residues
Levelling tractor wheel tracks
Breaking the surface soil crust
Removal of weeds at the white-thread stage
How the Green Way chain harrow works
16 rows for uniform cultivation
The harrow's working elements are arranged in 16 rows. As the machine moves, the tines successively loosen the topsoil, break clods, level the surface and distribute crop residues.
The flexible chain arrangement follows the field contours, keeping the tines in contact with the soil across the full working width.
Diamond-section tine made of 60С2А steel
Green Way is equipped with 1428 blade-like tines with a diamond-shaped cross-section, made of 60С2А steel. This shape enables effective soil penetration and reduces draft resistance compared with a standard square-section tine.
Six attack angle positions
The tine attack angle can be adjusted to field conditions and the required cultivation intensity. Two main positions are available — 38° and 50° — plus four additional positions set using a washer kit. This allows the best possible result to be achieved in a single pass.

Design features of the Green Way 21 m chain harrow
- In-house manufactured tines made of 60С2А spring steel, resistant to mechanical stress and abrasion.
- 16 harrow rows cultivate the soil successively.
- The trailed chain harrow has a working width of 21 m and a weight of 6450 kg.
- Changing from transport to working position takes 1 minute.
- Heavy-duty sections can be fitted behind the tractor wheels when working on heavy soils.
- The main frame is made from seamless 200 × 80 × 8 tubing in 09Г2С steel.
- 6 attack angles — the required result in one pass.
Additional options for heavy soils
Heavy-duty sections with reinforced tines behind the tractor wheels
Heavy-duty sections with reinforced tines behind the tractor wheels
For heavy and excessively compacted soils, Green Way can be equipped with heavy-duty chain harrow sections with reinforced tines.
The sections are fitted behind the tractor wheels and loosen compacted wheel tracks more intensively. This helps achieve a more uniform cultivation result across the full working width.
Using heavy-duty sections increases the required tractor power by approximately 10 hp.
Frequently asked questions
What tractor is required for Green Way 21 m?
A tractor with at least 340 hp is recommended for the standard configuration. Fitting heavy-duty sections increases the required power by approximately 10 hp.
What is the harrow's field capacity?
At a speed of 12 km/h, the calculated field capacity is up to 25.3 ha/h. Actual capacity depends on field conditions, terrain, harrow settings and working speed.
What is the working depth?
Green Way works at depths from 20 to 80 mm. Working depth and cultivation intensity are adjusted to soil conditions and the task.
How many tine attack angle positions are available?
Six attack angle positions are available: two main positions — 38° and 50° — plus four additional positions using a washer kit.
Can Green Way be used on heavy soils?
Yes. Reinforced sections are available for heavy and excessively compacted soils. They are fitted behind the tractor wheels to loosen compacted wheel tracks more intensively.
What should be clarified before ordering?
Provide information on the conditions in which the chain harrow will operate, soil types and tractor compatibility. Confirm the current price, manufacturing lead time, delivery and commissioning arrangements.
What is the fuel consumption of Green Way 21 m?
Estimated fuel consumption when operating the Green Way 21 m chain harrow starts from 4 l/ha. Actual consumption depends on the tractor model and power, working speed, field conditions, soil type and operating conditions.
Is Green Way 21 m suitable for a 340 hp tractor?
Yes. The recommended tractor power for Green Way 21 m is at least 340 hp, so a 340 hp tractor is suitable for this model. Actual tractive capability also depends on the tractor model, terrain, soil condition and moisture.
How does a diamond-section tine differ from a square-section tine?
The Green Way diamond-section tine is oriented relative to the direction of travel to reduce soil resistance during operation. This reduces the draft force required by the harrow, which is particularly important for wide implements.
The Green Way design also allows the tine to be set to 6 attack angle positions, adjusting its effect on the soil to field conditions and the task.
How many hectares can Green Way 21 m cover per shift?
The calculated field capacity of Green Way 21 m is up to 25.3 ha/h. During an 8-hour working shift, the theoretical area covered can reach 202.4 ha.
The actual area covered per shift depends on working speed, field shape, turns, travel between fields, terrain and other operating conditions.
What is the service life of Green Way tines?
The actual service life of the tines depends on soil type and abrasiveness, working speed, tine attack angle and operating conditions.
Practical experience with Green Way demonstrates the potential for long tine service life: our website features a video from ROST-AGRO showing the condition of the harrow tines after cultivating 10 000 ha.
This is an example of a specific harrow operating in real conditions, rather than a guaranteed service life for all operating conditions.
