is evident in fig4 the pegs 23 and 24 have facing surfaces 27 and 28 respectively that are beveled to assist the entrance of the edge 15 of the baffle therebetween the cylinder 25 of the actuator 17 is provided with hoses 29 and 30 which are in turn connected through a valve 31 to the pump 32 of a hydraulic system of the conventional type this would usually be the hydraulic system that provides the plow 12 with its operating fluid under pressure the operation and the advantages of the present invention will now be readily understood in view of the above description when the vehicle 20 proceeds in a forwardly direction its motor operates the pump 32 to provide hydraulic fluid both for the attachment 10 and for the snow plow 20 when not in use the baffle 14 is in the raised position shown in fig3 where it does not inhibit in any way the operation of the snow plow as the vehicle proceeds along the right hand side of the street plowing to the right the snow plow 12 would be inclined to the right to force snow in the right hand side of the vehicle onto the side of the road as a cross street or driveway is approached the operator actuates the valve 31 to energize the cylinder 25 of the actuator 17 this causes the actuator to expand from the position shown in fig3 to the position shown in fig2 thus pivoting the baffle 14 about the hinge pin 21 of the hinge element 11 the actuator operates in this way until the edge 15 of the baffle 14 contacts the forwardly directed surface 16 of the blade this edge is formed in such a way.
