FOLDING FOUR-ROW DISC TRAILED HARROW DANA BDP-8×4MTM
Capture width — 8 m.
Compared to double-row, four-row harrows provide more efficient tillage and require fewer passes. Harrow productivity - up to 12 hectares per hour, with a tractor of 400-450 hp: K-744P4, John Deere 9250, Buhler Versatile HHT-435, and other similar ones.
They are 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, smooths the surface of the field, combs out the weeds. |
| Rod-shaped roller | For medium and heavy soils. It creates a microrelief for sowing, crumbles, crushes lumps, and combs 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. |
