  • Patent number: 5485690
    Abstract: A lightweight snowplow configured of a number of small components, each easily lifted, moved, assembled, dis-assembled and stored by an average individual. The snowplow is especially suitable for use with small vehicles such as small trucks, utility vehicles and cars. The snowplow features novel alternate arrangements for operational lifting, stopping and lowering of the snowplow and a quick-hitch/release mechanism for easy plow attachment purposes. Finally, the mounting structure to which the plow is attached and detached is designed so as to be able to fit most small utility vehicles with two fore and aft frame chassis members and a frame mounted metal bumper without need for welding or special custom fit-up.
