ABSTRACT:
A boom assembly (B) is pivotally connected at one end with a prime mower (A) and at a second end with a mowing apparatus (C). An orientation control (D) controls the orientation of the mowing apparatus relative to the boom assembly such that the mowing apparatus can mow vegetation on vertical, sloping, or level areas with the boom positioned with varying degrees of extension. The orientation control (D) includes a hydraulic cylinder (60) which is pivotally connected at one end with the boom assembly and at its other end with a linkage assembly (62). The linkage assembly includes a first link (64) which is pivotally connected with the boom assembly and a second link (68) which is pivotally connected with the mowing apparatus and the first link. The linkage assembly converts the longitudinal extensive and contractive movement of the hydraulic cylinder into substantially 180.degree. of relative rotational movement between the mowing apparatus and the boom assembly.
