Abstract

In a tractor-mounted hedge-cutter or like machine in which a work-head (1) provided with a hydraulically driven rotary cutter is mounted on the outer end of an articulated, laterally extending boom (3, 6) of which the inner section (6) is pivotally mounted at its inner end on a frame (9) attached to the tractor, cooling of the oil in the hydraulic driving system for the rotary cutter is effected by passing the oil returning from a hydraulic driving motor (2) mounted on the work-head, first through a blister or cavity (28) provided in the cutter hood or guard (29) and then through the hollow interior of the boom section (6) to a storage tank (10) mounted on the frame (9). <IMAGE>
