A multi-blade pruning machine for pruning espalier vineyards comprises a supporting structure (2), first cutting means (3) comprising a plurality of first coaxial rotary blades (5) distributed along a first shared, substantially vertical axis of rotation (6) and second cutting means (4) comprising a plurality of second coaxial rotary blades (9) distributed along a second shared, substantially vertical axis of rotation (10). The first and second cutting means (3), (4) are, at least during use, brought close to one another so that the first and second blades (5), (9) are inserted between one another. Each first blade and second blade (9) has, around its circumference, along its outer edge, a plurality of teeth (21) alternating with a plurality of recesses (22). Each tooth (21) forms at least a front edge (23) with a recess (22) adjacent to it and positioned in front of the tooth (21) with reference to the blade direction of rotation. Each front edge (23) of each blade (5), (9) is rounded. <IMAGE> |
