ABSTRACT:
A snow tilling implement when mounted on a snowmobile and in operating position with the snowmobile in motion digs into the snow and sprays broken up snow on the heat exchanger, track, and slide rail on the underneath side of the snowmobile to cool and lubricate the same. The tilling implement can be simply an elongate rod, the proximal portion of which is advantageously bent to form a coil spring and catch arm. The catch arm abuts against the snowmobile and causes the coil spring to provide a downward force pressing the distal end of the rod into snow.
