Two-stage snow plow

A snow plow for mounting to a vehicle, comprising:

• a drive frame;
• a main plow coupled to the drive frame, said main plow having a left end and a right end;
• a secondary plow carried directly by the drive frame and positioned behind the main plow, said secondary plow having a left end and a right end;
• and,
• a member that couples the secondary plow to the main plow, wherein the member is configured to allow translation of the secondary plow relative to the main plow and in a direction that is substantially parallel to the main plow so that said left and right ends of said secondary plow are substantially aligned with said respective left and right ends of said main plow;
• wherein the secondary plow includes a plurality of fingers, each having a straight portion and a curved portion adapted for collecting snow.

• and
• a remotely controlled actuator, mounted to the drive frame and configured for selectively placing the secondary plow into a plowing position.

A snow plow for mounting to a vehicle,

• comprising:
• a first frame;
• a second frame coupled to the first frame for rotation about the first frame;
• a main plow having a scraping edge and mounted to the second frame, said main plow having a left end and a right end;
• a secondary plow, said secondary plow having a left end and a right end, said secondary plow being positioned behind said main plow;
• and
• a member that couples the secondary plow to the second frame, wherein the member is configured to allow translation of the secondary plow relative to the main plow and in a direction that is substantially horizontal and substantially parallel to the main plow scraping edge so that said left and right ends of said secondary plow are substantially aligned with said respective left and right ends of said main plow.
