Abstract: A snowplow for towing by a vehicle wherein the snowplow can be manually raised to a non-plowing position, and lowered to a plowing position by a user applying leverage to a fulcrum. The snowplow blade is attached to the snowplow from the non-plowing side of the blade, thereby alleviating attachment obstacles that inhibit the flow of snow to the ends of the blade during operation. Additionally, the snowplow has a blade attachment that allows the blade to follow ground surface undulations that can, e.g., cause the blade to be at an angle to the horizontal during operation.

Abstract: This method provides various high-power-ratio snow removal devices which clear paths narrower than the motor vehicles. We use small, light, low-priced, yet also safe, durable devices to clear the narrow swaths. High power ratios result from applying motor vehicle horsepower to small snow removal devices similar to those found on lawn tractors. Such devices may comprise moldboard plows (FIGS. 3, 9, 10, 11, 15, 16), snow throwers (FIGS. 7 and 13), or combinations of both types (FIG. 12 and 17). Quick-connect and quick-release fittings (FIGS. 3A, 3B, 6, 8, 9A, 9B, 14) position each device for temporary propulsion by a vehicle. The connectors allow quick conversion of the family car to a plowing machine, and when plowing is done, quick re-conversion. A moldboard plow of about half the car's width (FIG. 3) is our preferred embodiment. The mini-moldboard (FIG. 10) is least expensive. Deepest snow can be handled by our tall, narrow moldboard (FIG. 15).

The assembly further includes devices connected to the linear support member for offsetting the plow from the central longitudinal axis of the vehicle so that the plow is positioned in front of the tire path of and ahead of the direction of travel of the vehicle. The offsetting devices preferably comprise two pairs of piston-cylinder units. A first pair is mounted at one end to the front of the vehicle and at a second end to the linear support member. The second pair is connected at one end to the plow and at a second end to the linear support member.

Abstract: An air deflection system for a snow plow assembly mounted on a vehicle comprises an air stream guide member mounted on and overlying the upper surface of a snow plow blade. The guide member has a downwardly facing air inlet at a fore end positioned forward of the snow plow blade to intercept and capture without interruption an air stream which, by reason of forward movement of the vehicle, is directed toward the leading concave surface of the snow plow blade, then upwardly along that surface, and through a rearwardly facing air outlet at the aft end positioned aft of the snowplow blade. An air stream containment passage intermediate the air inlet and the air outlet is effective to receive the air stream from the air inlet and redirect it toward the air outlet from whence it is exhausted away from the snow plow blade and toward the radiator of the motor vehicle.

Abstract: An ATV lift handle is provided for an all terrain vehicle having a vertically movable blade at the forward end thereof.

Abstract: A removable V-plow system for a vehicle includes both a push bar and an idler bar that are positioned and sized so that the vertical orientation of the plow blades with respect to the vehicle chassis remains fixed as the plow blades are raised and lowered. Raising and lowering of the plow blades is accomplished automatically by an operator-controlled actuator mechanism accessible to the driver of the vehicle that provides power to an electric actuator to raise and lower the plow. By maintaining a fixed orientation for the plow blades with respect to the vehicle chassis, down pressure can be evenly distributed along the bottom cutting edge of the V-plow onto the ground surface even when the plow is in a forward V, reverse V, or diagonal configuration. The plow includes a simplified trip mechanism, and a mounting system that facilitates convenient mounting and dismounting of the plow from the vehicle.

Abstract: A wing plow yoke which may be manually actuated to laterally move outwardly from the front side of a plowing vehicle to allow access to the vehicle's hood, and thus to its engine. Mounting brackets attached to opposite sides of the front of the vehicle are provided with bracket apertures wherein a yoke bar is fit so that the yoke bar can move within the bracket apertures. A gear wheel or a fulcrum-and-lever arrangement is provided which engages a series of spaced depressions situated along the length of the yoke bar.
