The pre-sowing combined compactor is designed for accurate and high-quality preparation of the seed bed for demanding crops, such as sugar beet, rape, cereals, row crops, etc.
In one pass, the unit performs up to 8 operations:
Loosening the track of the tractor.
Primary leveling of the soil surface with a leveling bar.
Preliminary soil treatment with a front roller. The front roller grinds lumps on the surface.
A wrapper behind the front shredding roller returns unshredded soil clods back to the roller for
re-grinding. The height of the wrapper regulates the size of the soil fraction that should remain behind the roller.
Formation of the seed bed. Loosening and cutting weeds with arrows or chisels
paws to a given depth. The depth should be the same as the sowing depth. When using arrow paws, the soil is cut across the entire area and weeds are destroyed.
Additional grinding of the soil with a rear roller. It breaks the lumps that rise to the surface
after passing cultivator paws.
The wrapper behind the rear crushing roller regulates the size of the soil fraction that should remain behind
cat
Soil compaction with a rear roller. The roller finely grinds the remaining lumps and provides the final one
preparation of a seed bed with a completely restored soil structure. Restoration of soil capillarity draws moisture to the surface for uniform germination even in dry periods.
For better processing of uneven fields, the compactor has independent sections with a width of only 1.5 or 2 meters. Each section is suspended from the frame by means of a rigid rod, which gives it 3 degrees of freedom (oscillation along the rod, oscillation perpendicular to the rod, translational movements up and down).
