Abstract
Improved multiple plow, characterized by the adoption of a device formed by a tension spring adjustable at will by means of a nut capable of being screwed to one of the ends of an axis that crosses the spring and whose axis ends with a bevelled tip in the manner of ratchet retained - in normal position - by a notch of a terminal part of the support bracket of the bars, so that when encountering these with a resistance due to stones, roots or other obstacles, of intensity greater than that provided by the pressure of the spring , the aforementioned retention is released and the bars are raised oscillating around the axis of rotation without suffering damage or deterioration, and to return them to their normal position it is enough to push back the tractor, with which the bars operated in the opposite direction will force the terminal part of its supporting body to be inserted into the holding groove in the manner of a ratchet.
