Abstract
Removable universal tool-holder for mounting on a straddling vineyard tractor for agricultural work in tree or shrub plantations includes a main coupling chassis constructed so that it can be mounted, in a removable manner, on a straddling vineyard tractor; two secondary coupling chassis, each provided with a universal three-point hitch system; mechanisms connecting each secondary coupling chassis to the main coupling chassis; and mechanisms that make it possible to move each secondary coupling chassis in a vertical or approximately vertical plane and, preferably, in a horizontal or approximately horizontal plane. It is understood that the universal tool-holder can support machines constructed to accomplish cultivation or treatment work such as: hoeing, mowing, plowing, harrowing, spraying, thinning out leaves, pruning, lopping, etc.
