<p>A snow tiller (10) suitable for grooming ski hills, trails, or other areas, provides an adjustable snow housing assembly. A snow chamber (70) is formed between a ground shaping element (48) that has a rotatable drum (50) and a trailing finishing element (62) that is supported by a trailing bar bracket (84, 110, 130). The shape and/or volume of the snow chamber (70) can be adjusted by activating a finisher positioning mechanism (72), such as a hydraulic cylinder, to pivot the trailing bar bracket (84, 110, 130). A pair of connecting bars (98 and 100) from a pivot point about which the trailing bar bracket (84, 110, 130) pivots in an arc with respect to the snow surface, thus providing for precise positional control of the snow chamber (70).</p> |
