Abstract
A snow plow is detachably mounted to the front of a vehicle by interlocking members extending from the snow plow and vehicle. Engageable members on the plow are fixedly positioned a predetermined distance apart. Corresponding engaging members on the vehicle are displaceable between latching and unlatching positions by an over-center linkage arrangement. A first portion of the over-center linkage is pivotally connected to the vehicle. A second portion of the over-center linkage is slidably connected to the vehicle. Actuation of a hydraulic cylinder forces the over-center linkage to move from the unlatching position, wherein the blade and vehicle are disconnected, to the latching position, wherein the blade and vehicle are detachably connected. With the over-center linkage in the latching position, a toggle pin at the center moves against an abutment to lock the position of the over-center linkage, and therefore the plow onto the vehicle.
