Abstract: A pruning machine (12) for pruning vegetation growing on generally horizontal support wires. The pruning machine (12) includes a vertical shaft (22) mounted for rotation and at least one blade assembly (26) mounted on the shaft (22). The blade assembly (26) includes a plurality of blades (30) mounted to rotate with the shaft (22). The shaft (22) is threaded at least in the region where the blade assembly (26) is mounted. The vertical position of the blade assembly (26) on the shaft (22) is adjustable by an adjustment nut (56) which threadably engages the shaft (22) below the blade assembly (26) and which during adjustment, bears against the underneath of the blade assembly (26) so that rotation of the nut (56) upwardly of the shaft (22) raises the blade assembly (26) and rotation of the nut (56) downwardly allows the blade assembly to lower.

Abstract: Agricultural equipment for the removal of suckers that shoot from vine, plant or tree trunks. The equipment comprising an elongate, vertically oriented shaft (21) which has a plurality of cord connection points (26) spaced along its length. The cord connection points (26) are operable to releasably connect a flexible cord (27) to the shaft (21) for the purpose of adjusting the height of cords (27) connected to the shaft (21) to suit the height or length of the trunk being treated. A plurality of cords (27) are connected to the shaft (21) to at least some of the cord connection points (26), and a driving arrangement (25) is provided for driving the shaft (21) to rotate about its longitudinal axis.

Abstract: A pruning machine for pruning vegetation includes a frame arranged for connection to a tractor or the like so as to enable the machine to be moved along the vegetation to be pruned. A first pruning assembly is arranged for attachment to the frame, the first pruning assembly including first and second pruning apparatus arranged so that in use they can be positioned either side of a vegetation support wire on which required vegetation is located. The first and second pruning apparatus are arranged to prune non-required vegetation extending substantially above and/or below the support wire.

Abstract: A pruning machine, for pruning or trimming a row of vines or other plants, includes first and second sets of pruning apparatus. The first set includes a first mounting plate having a central axis and an outer edge, a first set of blades mounted on the first mounting plate and protruding outwardly from the outer edge, a second mounting plate having a central axis and an outer edge located close to the first mounting plate so that the respective central axes and outer edges substantially coincide, and a second set of blades mounted on the second mounting plate and protruding outwardly from the second mounting plate outer edge. In operation, the first set of blades rotates relative to the second set of blades so that scissor like cutting actions are formed between them. The blades on the first mounting plate and/or the blades on the second mounting plate taper from a broader width at the outer edge of the respective mounting plate to a narrower width at the point furthest from the central axis.
