Mowing, clearing or pruning machine for use with tractor, has balance beam and articulated jib forming telescopic articulated arm, inclination head mounted on end of balance beam, and protecting covers protecting flexible pipeline

摘要

The machine (10) has a pivoting block (12) rotatably mounted on a frame (11) around a vertical rotational axis (XX). A cylinder (19) articulates a jib (13) on the block around a rotational axis (YY) perpendicular to the axis (XX). A balance beam (14) has an end (14a) articulated on the jib around a rotational axis (ZZ) parallel to the axis (YY). The beam and the jib form a telescopic articulated arm (15). An inclination head (16) is mounted on an end (14b) of the beam. Protecting covers (13c, 14c) protect a flexible pipeline that supplies hydraulic fluid to the cylinder.
