A row crop cultivator for use in farming which includes a pair of weeding disks associated with each cultivator unit of which a plurality is ganged together in series. Each weeding disk is bearingly supported by a vertical shaft which is received by a cross bar in a manner which permits the shaft associated with the weeding disk to be adjusted as to depth and angular orientation. Such changes in the vertical shaft for the weeding disks are directly transferred to the weeding disk itself. Disposed adjacent the uppermost point of the shaft is a degree gauge plate and adjacent thereto is a depth gauge structured out of angle iron. As the farmer makes adjustments as to angular orientation and depth of one weeding disk, he need not be concerned with the specific values until the optimum depth and angular orientation have been found for the particular field being cultivated. Once this has been determined for a single weeding disk, all other disks of the cultivator can be almost instantly set to the same indicator values thereby duplicating the desired depth and angular position of the corresponding disks. Each weeding disk, degree gauge plate and depth gauge are supported by a corresponding frame which is pivotally hinged to the tool bar of the cultivator and positionable in either a weeding-disk up position or a weeding-disk-down position.
