Subsoilers are agricultural machines designed to work the soil at great depth. The hydraulic system of the tractor will allow the operator to choose the depth of work according to his needs. The main objective of subsoilers is to break up the ground while allowing better circulation of water from the deep layers of the earth. Normally they have between 3 and 9 arms and medium-high power tractors are required since the deeper you work, the more force you will need. Models come equipped with rear rollers and rollers that help break up the soil and offer good depth control.
