KOUTSIKOS subsoiler type CPR is a productive modern machine, designed to work in high speed and in great depth by medium and large horsepower tractors. The ploughshares work at every layer of the subsoil crushing the clods without agitating the soil and keeping at the upper ground level all the necessary organic substances. The rollers also assist in breaking large clods and leveling the surface of the field. As a result we have a field with good aeration and excellent subsoil drainage. Using the CPR subsoiler we succeed fuel and time save because tilling and leveling are achieved in one way of the tractor in high speed.
