A snow plow for attachment to a vehicle, the snow plow including a mounting apparatus having at least one mounting upright. The snow plow further including a plow blade including a retention apparatus constructed and arranged to slidingly and disengageably secure the plow blade to the mounting upright(s) when the plow blade is in a working orientation. The plow blade includes a limiting apparatus that limits upward movement of the retention apparatus. Preferably, the limiting apparatus includes a retention pin that can be secured within one of a plurality of vertically spaced apertures in the mounting upright(s) such that vertical positioning of the retention pin is adjustable. The snow plow further preferably includes a hoist or lifting upright having a lifting assembly, wherein the lifting assembly can raise the plow blade off of the ground.

The snow plow of claim 1, wherein the flexible elongated member in a sinuous relationship with the rollers. 3. The snow plow of claim 1, wherein an upper portion of the lifting upright is canted forward at an angle of from about 10 to about 15 degrees with respect to a generally vertical lower portion of the lifting upright. 4. The snow plow of claim 3, wherein the upper portion of the lifting upright is canted forward at an angle of about 13 degrees with respect to a generally vertical lower portion of the lifting upright. 5. The snow plow of claim 1, wherein the mold board includes a loop; wherein the attachment member is a clevis hook that can be secured to the loop to raise the plow blade above the ground. 6. The snow plow of claim 1, wherein the mounting apparatus includes two mounting uprights, wherein the lifting upright is spaced in between the mounting uprights. 7. The snow plow of claim 1, wherein the lifting upright has a top end and a bottom end, wherein the lifting upright is angled such that the bottom end is closer to the vehicle when the mounting apparatus is secured to the vehicle. 8. The snow plow of claim 1, wherein the mounting upright includes a plurality of apertures spaced vertically on the mounting upright; wherein the limiting member is a retention pin that is inserted through one of the plurality of apertures; the retention pin extending beyond a side of the mounting upright to limit upward movement of the retention apparatus when the retention apparatus slides upward with respect to the side of the mounting upright and the plow blade is in a working orientation. 9. The snow plow of claim 8, wherein the mounting apparatus includes two mounting uprights and the retention apparatus includes two retention members; wherein the limiting member includes a set of two retention pins that are inserted through respective apertures in one respective mounting upright; the retention pins extending beyond a side of the respective mounting upright at the upper end to limit upward movement of one respective retention member when the retention member slides upward on mounting upright and the plow blade is in a working orientation. 10. The snow plow of claim 9, wherein the retention pins are connected by a tensioned cord. 11. The snow plow of claim 1, wherein the plow blade includes a rubber scraper. 12. The snow plow of claim 11, wherein the retention apparatus at least partially encircles the mounting upright and allows the plow blade to pivot with respect to the mounting upright such that the rubber scraper can pivot away from the mounting upright when the plow blade is in a working orientation and the vehicle moves in a direction rearward from the plow blade. 13. The snow plow of claim 12, wherein the mold board has a main surface; wherein a projected intersection of a first plane of the mounting upright and a second plane of the main surface of the mold board defines a first angle, such that as the vehicle moves in a direction rearward from the plow blade and the plow blade is in a working orientation, the first angle increases. 14. A snow plow for attachment to a vehicle including a winch having a flexible elongated member, wherein the flexible elongated member includes first and second ends, the first end connected to the winch and the second end including an attachment member; the snow plow comprising: a mounting apparatus including at least two mounting uprights; a plow blade, the plow blade having a mold board including a main surface, a rubber scraper proximate the main surface and a retention apparatus constructed and arranged to disengageably secure the plow blade with the mounting uprights during use; the mold board further including connector; wherein the retention apparatus at least partially encircles the mounting uprights and allows the plow blade to pivot with respect to the mounting uprights such that the rubber scraper can pivot away from the mounting uprights when the plow blade is in a working orientation and the vehicle moves in a direction rearward from the plow blade; anda hoist assembly including a lifting upright positioned between the two mounting uprights, wherein the lifting upright has a top, a bottom, a top support and a bottom support, the top support being positioned proximate the top and the bottom support being positioned proximate the bottom; wherein the attachment member can be secured to the connector to selectively raise the plow blade. 15. The snow plow of claim 14, wherein the mold board includes a loop; wherein the attachment member is a clevis hook that can be secured to the loop to raise the plow blade above the ground. 16. The snow plow of claim 14, wherein retention apparatus includes a pair of retention members, wherein each retention member at least partially encircles one of the respective mounting uprights when the plow blade is in a working orientation. 17.
