FOUR-ROW TRAILED DISC HARROW DANA BDP BDP-3×4
Capture width — 3 m.
Compared to double-row, four-row harrows provide more efficient tillage and require fewer passes.
Harrow productivity - up to 3.84 hectares per hour, with a tractor of 150-250 hp: MTZ 1523, 2022, KhTZ-150, etc.
Designed for resource-saving pre-sowing and basic tillage to a depth of 8 to 15 cm for grain, industrial and fodder crops. It is used for grinding, leveling, and compaction of the soil, rejuvenation of meadows and pastures. Destroys weeds, crushes crop residues after harvesting crops.
Options
It can be equipped with various rollers depending on the type of soil
| Spiral roller | For dry and light soil. It crumbles and smoothes the surface of the field, combs out the weeds. |
| Cutaway roller | For light and medium soil. Fragments lumps, packs, and compacts the soil, levels the surface of the field. |
| Combined Roller | For medium and heavy soil. It creates a microrelief for sowing, crumbles, crushes lumps, and combes out weeds. |
It can be completed with various bearing units
| Maintained -free bearing assembly | It requires timely maintenance, but with proper care, it lasts longer. |
| Maintenance-free bearing assembly | The sealed unit does not need additional lubrication. |
It can be completed with various supports
| Conventional supports | The bearing assembly is located on the inside of a disc. Standard location. |
| Extended supports | The bearing assembly of the disk working body is located on the convex side of a disk. This reduces the load on the site, reduces traction resistance, which means it saves fuel and lubricants. Also, extended supports are much less clogged with plant debris. |
