摘要

Improvements in the tilting supports for plows and cultivators of agricultural machines, in which said supports are articulated by the upper part with the frame of attachment to the tractor having limited the advance movement by a stop, characterized by the blocking of the recoil movement it is carried out by a roller that moves along an elongated window of two tilting pieces on the frame, which rest against perpendicular arms and are integral with the frame itself, there being a strong spring whose tension keeps the aforementioned parts in contact with the perpendicular arms. To the frame, said spring yielding when the tool of the swinging support suffers a higher stress than the normal working, there also being springs that keep the locking roller at the ends of the elongated windows closer to the support but that yield and allow the displacement of the roller when the advance and start phase is carried out n position of work of the support, thanks to an escape profile in it.
