The hydropreumatic ripper is ideal for medium-high power tractors. The working depth varies from 40 to 60 cm, depending on the model, making it a very deep working depth. Constructed with a tubular structure, it is equipped with a nitrogen accumulator that preserves the integrity of the machine and at the same time drastically reduces the dead time due to the replacement of the safety bolt. When the obstacle is overcome, the hydraulic system will automatically return the anchor to the working position. The subsoiler can be applied to a double rear hydraulic roller for a perfect working of the ground.
