A vine or cane pruning apparatus, comprising a toothed wheel for guiding the pruning apparatus over vegetation in use, the wheel comprising a multiplicity of generally radially projecting teeth distributed about the periphery of the wheel for catching vegetation between gaps of the teeth, and wherein the wheel rotates by consequence of its engagement with the vegetation and vine or cane posts as the apparatus is driven along a row of vines or canes for pruning; and a driven rotary cutter mounted co-axially to the wheel for cutting vegetation caught between the teeth, the cutter being configured such that its effective cutting area falls within the diameter of the wheel.

A plant-trimming apparatus comprises two spaced-apart end plates, a rotatable tumbler, a rotatable reel comprising a reel shaft and reel blades, two bearing blocks, each detachably connected to a respective end plate and rotatably supporting a respective end of the reel, a motor arranged to drive the reel and the tumbler, a bed bar assembly comprising a bed bar and a bed knife, the bed knife being in operative engagement with the reel blade for cutting of plant material from the tumbler, and a manually-operated locking mechanism operable to secure the bearing blocks and the bed bar assembly to the end plates. The apparatus can be easily disassembled for cleaning and re-assembled, without using tools.

A machine for pulling off plant branches, in particular vine branches, of tying wires to which they cling by tendrils comprising a combination of means capable to extract the branches downwards. The combination of means comprises a (resiliently pivoted) pressing member and a pulling member facing the pressing member. In operation, the pulling member is moving so that its surface oriented towards the pressing member moves downwards. Cut-off branches are pressed on this surface by the pressing member by a force sufficient that the branches are dragged downwardly along and are forcibly detached from the tying wires. The downward removal corresponds to the about V-shaped ramifications of the plant, so that it is effected more easily and without obstruction by the ramifications which tend to get caught by the tying wires when removal occurs upwards. A branch not cut-off and tied to the trellis wire withstands the pressing member provided a suitable adjusted resilient pressing force is selected, supported by the pressing member consisting of a resilient material like an elastomer. Such a branch will not suffer any contact, or at least a minimal contact only, with the pulling device.

A device and method for removing leaves from a plant includes a downward extending and elongate support surface for supporting the plant and a pair of cutting devices disposed on either side of the support surface. Each cutting device includes a rotatable blade assembly and a grating which is disposed between the blade assembly and the support surface.

An apparatus for tending to rows of vines is presented which may be pulled, or driven, between a pair of rows of a vineyard. The apparatus includes implements to tend to the vines on both rows at the same time. The apparatus include a left portion that tends to a left row of vines and right portion that tends to a right row of vines. The portions are attached to the apparatus using linkages that permit the portions to adjust to changes in row spacing or the position of the apparatus between the rows. The apparatus also includes weeder assemblies that weed the ground between the vines while preventing damage to the vines, and a spray device for spraying the vines.

An apparatus comprising a chamber having a smooth inner surface, the chamber including a first hemisphere and a second hemisphere, wherein the first hemisphere is removably attached to the second hemisphere; a plurality of apertures located on a bottom center surface of the second hemisphere; a plurality of nozzles, each of the plurality of nozzles having an inlet and an outlet, wherein each of the outlets penetrate the plurality of apertures without intersecting the smooth inner surface; an air compressor; a compressed air regulator; an air hose connected to each of the inlets of the plurality of nozzles and the air compressor.

A double-stream stripping device, intended for the stripping of leaves from the vine, includes at least one stripping head (1) equipped with two counter-rotating drums (2) and (3), namely a first perforated (2a) drum (2) and a second drum (3) working in rotation with the first drum (2), a suction system (4) capable of creating negative air pressure in the first drum (2) and a system for driving drums (2) and (3) in rotation. The suction system includes two main suction openings and a turbine system and channeling elements (8, 9) making it possible to connect the latter to the main suction openings. Each open free end of the first drum is connected at one of the main suction openings in such a way as to create negative pressure, with a double air stream, constant and uniform, in the first drum, essentially over its entire length.
