A snow track maintenance system is described herein including a frame extending along an axis which is oriented along a direction of displacement, a mounting assembly secured to the frame for mounting the frame to a motorized vehicle so as to be trailed therefrom along the direction of displacement, and a leveler mounted to the frame so as to be pivotable relatively to the direction of displacement. Other equipments may further be provided to the maintenance system, including a snow regenerator mounted to the frame along a first longitudinal axis generally perpendicular to the direction of displacement, and a snow compactor mounted to the frame upstream from the snow regenerator. The system can be used for the maintenance of alpine ski tracks and cross-country ski tracks, even in an underbrush trail, and allows setting a track on any type of snow.
