BDM-P «BARS» 4-Row Disk Harrows (trailed and mounted) on spring tine 2.4 to 9.2 m Wide

BDM-P «BARS» is an advanced 4-row disk harrow on spring tine. The bearing assemblies are installed inside the disk sphere; each disk is attached to a separate tine. It is designed to till the top soil layer up to 17 cm deep, to destroy weed and to chop up crop residues. The disk harrow efficiently operates on soils exposed to wind or water erosion since it uniformly mixes the soil with crop residues. Crop residues uniformly mixed with the top soil layer prevent the soil from being blown or washed away and improve air exchange. Crop residues in the soil are intensively turned into mold improving soil fertility.

The 4-row disk harrow can be used in a wide range of Russian agro-climatic zones and can handle all kinds of soil including stony ones. The harrow is an efficient tool for fallow land reuse, preseeding and primary treatment for the min-till approach, renovation of degrading grasslands and grazing areas.

The key BDM-P BARS harrow feature is that the disk gang arm is made of a rectangular cross section, triple-twisted spring steel. The arm tip is sufficiently rigid while its stroke is long enough. This allows the disk to pass hard obstacles without any damage.

BDM-P «BARS» 4-Row Harrow Features Compared to 2-Row Harrows:

• 4-row harrows have a relatively large disk-to-disk distance in a row. The disk-to-disk distance in a row is 460 mm, while the row-to-row distance is 675 mm or 900 mm. Therefore, the soil lifted by a row of disks easily passes between the next row disks. So a 4-row harrow can operate in very weed-choked fields and at greater depths.

• The longer frame better absorbs the unevenness of the ground. 4-row harrows are also perfect land planning tools. They easily remove back ridges, backfurrows, deep wheeltracks, moles, etc. A 4-row harrow is your best choice for fallow land reuse.

• All disk tools face a problem: each row of disks tries to pull the harrow in the direction of the disk rotation. The tool turns about the tractor hitch. Since the rows of disks are located at different distances from the hitch, each row applies different loads to the tool. This results in an irregular disk pattern. The rear disks hit the furrows made by the front disks, which leads to poor performance. Each disk tool has its own way of resolving the problem. BRAND NEW! BDT-AGRO launches a new line of 4-row harrows with a new patented disk arrangement. 4-row harrows are perfectly balanced: no imbalance! Neither 2- nor 3-row harrows can be so stable.

Key Advantages of 4-Row Harrows BDM-P «BARS»:

1. Originally, 4-row harrows with separate holders for each vertically tilted disk had a disk-to-disk distance of 400 mm within a row. Then this distance was simply divided by the number of rows. So the offset for each holder with respect to the frame came up to just 100 mm. It should be noted that each disk is vertically tilted and its lowermost point almost never matches the holder pivot axis. This resulted in an irregular disk pattern. Many harrow manufacturers still use such an arrangement. Based on the studies performed, BDT-AGRO has developed and tested a new, improved disk layout. The 4-row harrow disk-to-disk distance is 460 mm. For this reason, lower tractor power is required, and up to 12 % of fuel is saved compared to the same-width tools from other manufacturers, while preserving the soil processing quality.

2. All disk tools face a problem: each row of disks tries to pull the harrow in the direction of the disk rotation. The tool turns about the tractor hitch. Since the rows of disks are located at different distances from the hitch, each row applies different loads to the tool. This results in an irregular disk pattern. The rear disks hit the furrows made by the front disks, which leads to poor performance. Each disk tool has its own way of resolving the problem. BRAND NEW! BDT-AGRO launches a new line of 4-row harrows with a new patented disk arrangement. 4-row harrows are perfectly balanced: no imbalance!

3. All the tools have a depth adjuster (press wheel) as standard. The press wheels are arranged in a line right behind the disks. The soil lifted by the disks falls exactly on the wheels. The wheels and disks operate together to grind and level the soil better. The wheels arranged in a line receive the same load from the entire tool. Loads caused by the tractor pitching and rocking are much lower because the wheels are installed close to the disks and the wheel vibration amplitude is substantially shorter. Since the vibration amplitude is short, simple wire stretchers are used instead of spring shock absorbers. The new design is simpler and more reliable.

4. There are a number of different press wheels available: helix, slatted, helix-slatted, toothed, or disk (ring) ones.

The slatted and helix-slatted wheels from BDT-AGRO are designed in such a way that the slat penetrates the soil nearly vertically and is retracted almost horizontally. These wheels perfectly lift, remove ridges and level the field after a pass.

When the soil is loose (for example, during tilling operations), the wheels may get stuck and filled up with soil. In this case, turn the wheels 180°. The slats will penetrate the soil horizontally and be retracted vertically. This expands the wheel ground contact area while the wheel catches less soil with fewer chances of getting stuck.

5. The tensile spring gang arms are more reliable than compressive gang arms provided by competitors. The coils of compressive spring gang arms strike each other when operating and the arm is worn out at the strike point. Eventually, this could lead to the arm breakage. The tensile spring gang arms are unique on the domestic and global market. The spring gang arms we have developed are manufactured by BELOTTA, Spain, with the use of our drawings.

6. Bumpers made of rubber or polyurethane wear out over time and when exposed to temperature variations. The steel spring gang arm has a longer service life; it is durable and withstands winter frost and summer heat.

7. When a disk runs into a hard obstacle its spring gang arm can deflect both upwards and sideways. This improves the tool reliability when working on stony soil.

BDM-P «BARS» 3-Row Disk Harrows (trailed and mounted) on spring tine 2.1 to 9.1 m Wide

BDM-P «BARS» is an advanced 3-row disk harrow on spring tine. The bearing assemblies are installed inside the disk sphere; each disk is attached to a separate tine. It is designed to till the top soil layer up to 17 cm deep, to destroy weed and to chop up crop residues. The disk harrow efficiently operates on soils exposed to wind or water erosion since it uniformly mixes the soil with crop residues. Crop residues uniformly mixed with the top soil layer prevent the soil from being blown or washed away and improve air exchange. Crop residues in the soil are intensively turned into mold improving soil fertility.

The 3-row Disk harrow can be used in a wide range of Russian agro-climatic zones and can handle all kinds of soil including stony ones. The harrow is an efficient tool for fallow land reuse, preseeding and primary treatment for the min-till approach, renovation of degrading grasslands and grazing areas.

The key BDM-P BARS harrow feature is that the disk gang arm is made of a rectangular cross section, triple-twisted spring steel. The arm tip is sufficiently rigid while its stroke is long enough. This allows the disk to pass hard obstacles without any damage.

BDM-P «BARS» 3-Row Harrow Features Compared to 2- and 4-row Harrows:

• 4-row harrows have a relatively small distance between the rows, that is 675 mm. As harrows are transported as metal frame structures, the row-to-row distance is limited by shipping concerns. As a result, the soil lifted by the front disk rows prevents the rear disks from operating efficiently. To avoid jamming, the user either has to slow down or decrease the operating depth. 3-row harrows have a smaller disk-to-disk distance in a row, 350 mm, while the row-to-row distance is much longer, that is 950 mm. Each disk coverage and overlap are similar for 3- and 4-row harrows. So both 4- and 3-row harrows can operate on very weedy fields and at greater depths.

• The first-to-last row distance is the same for 3- and 4-row harrows. The longer frame better absorbs the small unevenness of the ground. 3-row harrows are also perfect land planning tools. They easily remove crown ridges, backfurrows, deep wheeltracks, molehills, etc. The 3-row harrow is your best choice for fallow land reuse.

Key Advantages of 3-Row Harrows BDM-P «BARS»:

1. 1. Originally, 3-row harrows with separate holders for each vertically tilted disk had a disk-to-disk distance of 300 mm within a row. Then this distance was simply divided by the number of rows. So the offset for each holder with respect to the frame came up to just 100 mm.

2. All the tools have a depth adjuster (press wheel) as a standard feature. The wheels installed behind the chassis are adjusted with spring shock absorbers. This significantly reduces loads applied to the tool as it moves over rough terrain or when the tractor pitches and rocks.

3. On modular harrows the press wheels are arranged in a line right behind the disks. The soil lifted by the disks falls exactly on the wheels. The wheels and disks operate together to grind and level the soil better. The wheels arranged in a line receive the same load from the entire tool.

BDM-P «BARS» 2-Row Disk Harrows (trailed and mounted)
on spring tine 1.8 to 9.2 m Wide

BDM-P «BARS» is an advanced 2-row disk harrow on spring tine. The bearing assemblies are installed inside the disk sphere; each disk is attached to a separate tine. It is designed to till the top soil layer up to 15 cm deep, to destroy weed and to chop up crop residues. The disk harrow efficiently operates on soils exposed to wind or water erosion since it uniformly mixes the soil with crop residues. Crop residues uniformly mixed with the top soil layer prevent the soil from being blown or washed away and improve air exchange. Crop residues in the soil are intensively turned into mold improving soil fertility.

The double Disk harrow can be used in a wide range of Russian agro-climatic zones and can handle all kinds of soil including stony ones. The double harrow is an efficient tool for treating space between rows in gardens and vineyards, preseeding and primary treatment for the min-till approach.

The key BDM-P BARS harrow feature is that the disk gang arm is made of a rectangular cross section, triple-twisted spring steel. The arm tip is sufficiently rigid while its stroke is long enough. This allows the disk to pass hard obstacles without any damage.

BDM-P «BARS» 2-Row Harrow Features Compared to 3- and 4-row Harrows:

• The double harrows have a smaller disk-to-disk distance in a row — 300 mm, while the row-to-row distance is 1,000 mm. The double harrow disks only partially overlap each other. The gaps between the disks are also tilled since the second row disk removes soil and shifts it into the backfurrow made by the first row disk. This does not always happen. However, a second pass diagonally to the first one results in perfect field tilling: the gaps left after the first pass are sliced, and the ridges are removed. As the double harrows have the same number of disks, but are wider, productivity is higher and fuel consumption per area is lower.

• Double harrows are much shorter. They are easier to steer and have a smaller turn radius. For the same reason many double harrows are mounted tools: they apply lower loads to the tractor linkage. Mounted double harrows are significantly cheaper, simpler and easier to steer compared to trailed ones.

• Due to the shorter disk-to-disk distance in a row, double harrows are not as good at negotiating foul and wet fields as 3- or 4-row tools. However, for this very reason double harrows make smaller ridges. It is better to use double harrows for smaller ridges, regular tilling of low-foal fields and for preseeding operations.

Key Advantages of 2-Row Harrows BDM-P «BARS»:

1. Based on the studies performed, BDT-AGRO has developed and multiply tested a new, improved disk layout. The BDM double harrow disk-to-disk distance is 300 mm compared to 270 mm for tools from other manufacturers. For this reason, lower tractor power is required and up to 12 % of fuel is saved compared to same-width tools from other manufacturers while preserving the soil processing quality.

2. All the tools have a depth adjuster (press wheel) as standard. The press wheels are arranged in a line right behind the disks. The soil lifted by the disks falls exactly on the wheels. The wheels and disks operate together to grind and level the soil better. The wheels arranged in a line receive the same load from the entire tool. Loads caused by the tractor pitching and rocking are much lower because the wheels are installed close to the disks and the wheel vibration amplitude is substantially shorter. Since the vibration amplitude is short, simple wire stretchers are used instead of spring shock absorbers. The new design is simpler and more reliable.

3. 3. There are a number of different press wheels available: helix, slatted, helix-slatted, toothed, or disk (ring) ones.

The slatted and helix-slatted wheels from BDT-AGRO are designed in such a way that the slat penetrates the soil nearly vertically and is retracted almost horizontally. These wheels perfectly lift, remove ridges and level the field after a pass.

When the soil is loose (for example, during tilling operations), the wheels may get stuck and filled up with soil. In this case, turn the wheels 180°. The slats will penetrate the soil horizontally and be retracted vertically. This expands the wheel ground contact area while the wheel catches less soil with fewer chances of getting stuck.

4. The tensile spring gang arms are more reliable than compressive gang arms provided by competitors.

6. When a disk runs into a hard obstacle its spring gang arm can deflect both upwards and sideways. This improves the tool reliability when working on stony soil.
