The machine, that can be used especially on runner-system or guyot type support structures, is made by a tunnel frame on which two cutter bars (double-blades), enable to cut the strongest vine shoots, are applied. The machine has also a particular extractive system for the vine runners enable to carry them to the row centre leaving clean the underlying zone. On choice the vine runners can be both cut or left entirely; in the second case the removal operation is more easily.
