A snow tiller (10) suitable for grooming ski hills, trails, or other areas, provides an adjustable profile tiller assembly. The snow tiller (10) is preferably pulled by a tracked vehicle (12) and has a tiller assembly formed of a plurality of tiller subassemblies (56, 58). By varying the respective orientation of the tiller subassemblies (56, 58), the snow tiller (10) can selectively provide concave, level, convex, or more complex snow profiles depending upon the tiller configuration, snow conditions, and the intended uses. The snow tiller (10) also provides a control system to substantially maintain a selected snow profile while selectively permitting individual tiller subassemblies to float, thereby reducing the possibility of damage. The assembly can simultaneously provide an automatic release mode to protect the equipment from damage.
