Abstract: The invention is a trailer-type snowplow assembly. The assembly includes one pivot mechanism that allows the plow blade to be raised or lowered. The assembly further includes a free pivot assembly that allows the blade to freely pivot in a transverse direction in response to directional changes of the tow vehicle or uneven snow impact along its length. Also disclosed is a multi-piece plow blade that has removable end portions that allow a user to elongate or shorten the effective length of the plow blade.

Abstract: Disclosed is a snow plow carried on the rear of a vehicle with its plow blade disposable in positions of raised or lowered elevation, and disposable in positions of traverse. The snow plow is so carried by means of a receiver carrying a tongue fixed to a pedestal assembly to which is fixed a pintle which freely carries a rotatable sleeve to which is fixed a first rectangular tubing pivotally mounted with a second rectangular tubing to which the plow blade is affixed. A winch cable engaged with the second tubing raises and lowers the plow blade upon operation of the winch. A clevis pin is engageable with alignable sets of holes through the pintle and sleeve to lock the plow blade in discrete traverse positions.
