ABSTRACT:
There is provided a coupling section which comprises a main planar body having an aperture at one end. Extending from the main planar body on a first side is a rod. Secured to the end of this rod is a depending flange having an aperture coaxial with the aperture in the main body. An extending tab is secured to the vehicle body and is aligned between the flange and the main body. The tab has an aperture which, when aligned with the apertures in the flange and main body, provide a pivot point when a suitable pin or bolt is inserted through the apertures. The other side of the planar body contains a box-like housing having an extending rod to which a movable piston associated with a hydraulic cylinder is coupled. The cylinder body is rigidly secured to the vehicle chassis. The front end of the planar body has a transverse flange to which one end of a cutting head support beam is coupled. The other end of the beam is coupled to one side of a cutting head assembly. The above described coupling apparatus is employed at both ends of a cutting head and hence, identical coupling sections are employed to provide support for two beams between which a cutting assembly is positioned.
