ABSTRACT:
A snow pusher attachment for use in conjunction with a straight blade angle-type snow plow mounted to a work vehicle is disclosed. The attachment consists of side panels, connected by horizontal members. The pusher attachment is secured to the snow plow by bracket assemblies, attached to the upper edge of the snow plow that engage hooks on the upper, rear portion of the pusher attachment. The pusher can be secured or released from the snowplow by manipulation of the plow blade allowing quick and repeated conversion of a snow plow into a snow pusher box and visa versa.
