Abstract: A manually operated snow plow has a frame which is mounted on a wheel and axle assembly so that it can be pushed along the ground. A snow scoop is rotatably mounted within a pan which is positioned just above the ground surface and securely connected to the front of the frame. The scoop is spring powered so that when the scoop has collected a load of snow the scoop can eject the snow (in a flipping motion) to the side of the area being cleared. A latch retains the scoop in position within the pan and against the spring tension. Manual release of the latch by means of a simple cable connection thus activates the spring mechanism of the scoop to eject the snow. After the scoop has ejected the snow, a handle positioned at the rear of the frame allows manual retraction of the scoop into the pan thereby bringing the scoop into a position where it can receive another snow load and simultaneously loading the spring mechanism.
