Quick-release skis couple to the front wheels of an ATV or other wheeled vehicle, to permit the ATV to travel over snow. The rear ATV wheels may be left unaltered, or more commonly, tracks may be substituted for the rear wheels. The ski coupling includes a drive-on runner and coupling having in one embodiment width-adjustable side walls, an over-center clamp, and a lock for securing the over-center clamp. In a second embodiment, a pivotal tire cage allows the ATV tire to be driven onto the ski, but simply by forward travel of the tire the cage pivots to constrain the tire thereon. A strap then binds the tire and cage to ensure the tire stays in place on the ski. In a third embodiment, an ATV track is converted to a runner by the application and tensioning of a ski. Additional embodiments are illustrated.

1. A quick-release ATV ski, comprising: a ski-shaped wheel support;a pair of wheel receivers extending longitudinally along and rising from said ski-shaped wheel support and spaced laterally from each other to define a wheel cage;a strap anchor adjacent a first end of said wheel cage;an over-center clamp adjacent a second end of said wheel cage distal to said first end;a strap coupled between said strap anchor and said over-center clamp;a removable lock positively engaging said over-center clamp and thereby preventing accidental release of said over-center clamp; anda strap adjuster having: a body;a pair of spaced slots formed through said body and through which said strap passes and configured to allowing a length of said strap to be adjusted; andteeth coupled with and extending from said body and configured to engage with a wheel retained within said ski-shaped wheel support. 2. The quick-release ATV ski of claim 1, wherein said pair of wheel receivers are spaced laterally from each other by an adjustable distance. 3. The quick-release ATV ski of claim 1, wherein said pair of wheel receivers further comprise side walls and at least one front wheel stop. 4. The quick-release ATV ski of claim 1, wherein said pair of wheel receivers and said ski-shaped wheel support define a drive-in wheel cage. 5. The quick-release ATV ski of claim 1, further comprising a plurality of holes spaced varying distances from said over-center clamp, each serving as an available receiver for said strap anchor. 6. The quick-release ATV ski of claim 1, further comprising a strap coupler coupled with said strap intermediate between said strap adjuster and said over-center clamp, said strap coupler having: a coupler body;a pair of spaced slots formed through said coupler body and through which said strap passes and configured to allowing a length of said strap to be adjusted; andcoupler teeth coupled with and extending from said coupler body and configured to engage with a wheel retained within said ski-shaped wheel support. 7. In combination, an ATV endless track, a ski, and a tensioning member, wherein said ATV endless track is uncoupled from a rotary drive and defines a ground contact region between at least two track wheels,wherein said ski is immediately adjacent to and covering said ATV endless track ground contact region and thereby isolates said ATV endless track ground contact region from direct contact with a ground surface, andwherein said tensioning member retains said ski in position immediately adjacent to and covering said ATV endless track and between said ATV endless track and said ground surface. 8. The combination ATV endless track, ski, and tensioning member of claim 7, further comprising a pair of track receivers extending longitudinally along and rising from said ski and spaced laterally from each other to define a track cage. 9. The combination ATV endless track, ski, and tensioning member of claim 7, wherein said ski is in direct contact with said ATV endless track ground contact region. 10. The combination ATV endless track, ski, and tensioning member of claim 7, wherein said ski is conformal. 11. The combination ATV endless track, ski, and tensioning member of claim 10, wherein said ski is adapted to roll into a storage configuration. 12. The combination ATV endless track, ski, and tensioning member of claim 10, wherein said conformal ski extends more fore and more aft than said ATV endless track ground contact region and rises both fore and aft therefrom. 13. The combination ATV endless track, ski, and tensioning member of claim 12, wherein said ski is provided with at least one of a hook and eye, and said tensioning member is provided with another of said hook and eye and engages with said at least one of said ski hook and eye.
