The operator acts from the ground and with a minimum of manual effort, this effort consisting of opening and closing one of the two carrier arms 1-2 supporting the compact assembly. Its most important systems are: system for adaptation to variable heights - by means of the main bar 6, the set of support arms 1-2 slides externally and, via the inside, there slides an extension bar 7; System for working with different cutting angles - it consists of a flexible articulated portion 9 which is inserted between the extension bar 7 and the hydraulic receiving cylinder 12; Hydraulic system - by manually articulating the arms 1-2, we actuate the propulsion hydraulic cylinder 10, displacing its fluid via a flexible conduit 11 to the receiving cylinder 12 which supports and activates the cutting tool 13. <IMAGE>
