An implement for mounting on a tractor to remove suckers and buds from the stems of vines arranged in rows and for trimming during the advance of the tractor along the ground in a direction essentially parallel to, adjacent and between the row of vines, including, a frame supported on a tractor, opposing side arms on the frame arranged on opposite sides of said tractor, removable interchangeable brush treating devices mounted on the outer end of each of the side arms, a drive on the side arms for moving the brush treating device for independent operation on both sides of said tractor, a linkage for mounting the side arms for lateral pivotal movement and for extending the side arms outwardly to a selected distance so as to be able to approach the rows of vines to be treated either on one side or other of the tractor and at the desired height. A hydraulic control system for raising and lowering the frame with respect to the tractor. Each of the brush treating devices comprising interchangeable vertical shaft rotatably driven by the drive, a plurality of flails radially supported on the vertical shaft so as to form a vertical cylindrical rotating brush for brushing the vine stems, the plurality of flails being separated in vertical sections mounted at different heights on the vertical shaft, the side arms being arranged to also support a scythe bar in substitution for the brush treating device for vertical trimming of the vines in the rows.
