Ploughbase deflecting hoe elements for a symmetrical plough according to Claim No. 1 of the main patent, characterised in that alternately along the working direction, when the hoe elements of one same side are placed to fulfil their "hoeing" function in front of the mouldboard 4 of the base, the other opposite ones are placed in the "following the mouldboard" position of the base with the possibility of varying this position due to the fact that the handle of the said hoe elements is composed of a minimum of two lengths 12 and 17 articulated to each other and the overall unit connected to an elastic element, in that in the working "hoeing" position the ploughshare of the latter is at a level which at the very minimum is equal to, or even less than, that of the outer part of the mouldboard located behind it. <IMAGE>
