摘要

The pollarding and pruning machine is for vines etc. growing in rows, comprising a chassis with a central vertical member (2) on which two guides (5,6) are mounted, one at least being adjustable for height. Each guide supports two symmetrical hinging arms (9,10), forming with the arms hinging on the other guide a distorting parallelogram frame (12). On the two lateral spindles (11) of the frame, fittings (13) are mounted supporting the rotary knives (18,19,34) for pruning and/or pollarding, and which are coupled to a drive mechanism (20).
