Stubbly aggregate -
- GRUBER

---

The stubble field GRUBER unit is intended the postharvest cultivation on every kind of the soil. It consists:
— Cultivator with two rows catch with side ploughshares, which trip up, revert and aerate soil, as well as they mix it up with postharvest remains;
— section of adjusted obliquely platefuls;
— tubular shaft, which smooths surface of the field and flattens the aerated soil in order to hasten its settling and better permeating water.
Using high-quality materials allowed to optimize mass and dimensions of the unit at keeping the right durability what appropriate using the power of the tractor guarantees. The stubble field GRUBBER aggregate is found in two options of the protection: cutting (stake) and non stop (spring), so it can be applied on soils about the different amounts of stones. Screw protecting the section of plates is an additional advantage that protects them against mechanical damage.
