Abstract: A manually adjustable snowplow apparatus for mounting to an all terrain vehicle comprises a blade assembly pivotally mounted to a frame member of the ATV and adapted for relative up and down movement. The snowplow apparatus further includes a vertical plate mounted to the ATV and forming a plurality of spaced apart notches. A handle is pivotally attached to the plate and includes a rod that selectably mates with one of the notches. A cord extends between the handle and the blade assembly such that a forward or rearward movement of the handle decreases or increases, respectively, the height of the blade assembly above a ground surface.
