摘要

Harrow for work in vineyards, which is constituted from a chassis with its corresponding means of mooring to a tractor vehicle and on which are mounted a plurality of discs for the working of the land, is characterized because the chassis is symmetrical with respect to its central and longitudinal axis, said chassis including some lateral parts telescopically coupled to the central part, allowing the extensibility of said chassis and therefore of the own harrow; with the particularity that the discs are mounted in two parallel rows, one anterior and one posterior, the discs being interspersed in one alignment with those of the other and fixed in pairs by pairs with a slight frontal inclination of the discs; having provided a central and lower arm for breaking the ground remaining between the central discs, as well as coupling points for possible counterweights, in order to increase the weight of the harrow, comprising means for optional mounting of a roller, harrow or board, which makes it possible to control the depth of work, also incorporating two conventional fork-type hooks with bolts and bolted-on stub axle type, and a quick bar hitch with two locking triggers of the bar itself in its housing.
