The use of pneumatic shears in conjunction with the pruning sled concept resulted in maximum cane cutter productivity, but the overall productivity with the three-man crew was less than that demonstrated for the two-man crew using only pneumatic shears. The tests demonstrated that, in terms of overall crew productivity the use of pneumatic shears was definitely advantageous. However, purchase of a pneumatic pruning machine cannot be justified if used only for cane severing.
