<p>Provided is a novel subsoiler machine that includes a protection mechanism against surcharges, the mechanism being actuated by a couple of springs, a tension spring and a compression spring, the subsoiler comprising at least two tines with shoes at different levels in order to abate the power consumption. Once the protection mechanism is activated, the deactivated tines are reactivated by only moving the tractor backwards.</p> |
