A ski run snow preparation apparatus having a snow-contacting blade which flexes laterally to provide an arcuate snow-contacting surface. The blade is pivotally mounted to a frame which is adapted to be secured upon the towing mechanism of a suitable tracked vehicle. Also mounted upon the frame is a remotely controllable mechanism, including a pair of hydraulic motors, to adjust the tilt of the snow-contacting blade in relation to the snow surface. The blade may operate under its own weight and that of the towing mechanism, or may be forceably pressed into the snow, as by vehicle mounted hydraulic motors provided to raise and lower the towing mechanism.
