Harrow capture width - 6 m.
This is a reinforced version of the 6 × 2 harrows. The frame, the nodes for transferring into the transport position, and the attachment points of the working bodies were enforced. Folding harrow: folds hydraulically and can be transported on public roads.
It is aggregated with tractors with a 300-350 hp capacity: MTZ 3022, K-700, K-701, K-744, and others. Harrow productivity up to 7.2 ha/h.
Designed for resource-saving pre-sowing and basic tillage to a depth of 8 to 12 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.
|Cutaway roller||For light and medium soil. It fragments lumps, packs and compacts soil, levels the surface of the field.|
|Plate roller||For medium and heavy soil. It creates a microrelief of soil for sowing, crumbles the soil, crushes lumps, and combes out weeds.|
|Maintenance-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.|
