Abstract:

A mechanical cutter (similar to a special sprinkler for chemical pruning) serves toprune new hopvine shoots in spring. Depending on the right timing and quality of pruningdepends the later yield, which is why pruning is one of the most important agrotechnicaloperations. Double-disc mechanical cutter used with high trellises cannot be used with thetechnology of low trellises. Due to the effort to minimise the chemical environmental burden,special sprinklers for chemical pruning used abroad are considered inappropriate. This was thereason which led to a design for a mechanical cutter operating in low trellises. The articledescribes a hydraulic circuit design and laboratory measurements of an experimental model ofmechanical cutter.
