Abstract

Cordon-trained grape vines are pruned by positioning circular saw blades to form a cutting path of predetermined size and shape above and on both sides of the horizontal trellis wire on which the cordons are trained and by translating the cutting path along the trellis wire while maintaining the size and shape of the cutting path substantially constant, while maintaining the sides of the cutting path centered on the cordons and maintaining the upper part of the cutting path at a desired height above the cordons.
