ASTRA rotor harrows are used to loosen the soil and remove weeds. They can be used in all soil conditions, they are especially useful for heavily dried soil.

The applied rotary rotors perfectly break up the soil crust. The weeds are pulled out and are left on the surface because the soil is heavier and sinks to the ground faster. The harrows can be used in almost all crops such as: corn, sunflower, soybeans, etc. with a plant height of 10-25 cm. Driving speed 10-25 km/h. Rotary rotors are made of special cast iron, mounted on rolling bearings. They are mounted oscillatingly to a special spring tooth 25×25 mm ensuring the appropriate pressure. The high speed of the harrow reduces costs and shortens the time of care treatments.
