Abstract: A snowplow assembly comprises a lift frame and A-frame operably pivotally connected together and an actuator operably connected between the lift frame and A-frame for effecting relative pivotal movement between the lift frame and A-frame. A plow blade includes a blade frame. The blade frame includes a tube of circular cross section which is operably pivotally connected to the A-frame. The tube is pivotally received by a quadrant, which is operably connected to the A-frame. A resilient element is operable between the blade frame and A-frame normally biasing a lower edge of the plow blade forwardly. The resilient element is an elastomeric loop. The pivotal connection of the plow blade to the A-frame in combination with the resilient element provides a trip function of the plow blade. The plow blade is a composite. The circular tube of the blade frame provides torsional stiffness to the composite blade.

Abstract: An improved snow plow for use with light and medium duty trucks is disclosed which has a frame which uses an in-line design to eliminate the presence of rotational or torsional force in the frame members of the snow plow, which design provides an improved degree of ground clearance as well.

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: An improved manually pushed snow shovel in which the user's natural pushing force acts to alleviate stalling friction. A version of a manually pushed snow shovel having features of this invention comprises a blade with a leading edge, a handle attached to the blade, and at least one, although two are preferred, ski runner(s) attached to the blade. The ski runner(s) are attached such that when in the shovel is in use, the leading edge of the blade is at or behind the portion of bottoms of the ski runner(s) normally in contact with the ground. This ensures that the shovel pivot point or point of downward vertical force from the snow load is forward of the leading edge relative to forward movement of the shovel. As such, the user's natural forward pushing on the handle and hence indirectly to the blade results in the leading edge moving upwards away from the ground upon encountering increased friction due to heavy snow or rough ground surfaces.

Abstract: The present invention comprises one or more anti-drift stabilizers mounted on the leading edge of a snow plow's blade. These stabilizers are mounted at an angle that is in the same direction as the angle of the snowplow in relation to the plow truck. As snow or other media is channeled to one side of a plow blade it exerts a force in the opposite direction thus tending to cause a plow to want to knife or drift in a direction opposite where the snow or other media is being deposited by the blade. As snow or other media passes over the surfaces of the stabilizers it exerts pressure that is opposite to, and counteracts the knifing action created at the emptying end of the plow by the accumulation of snow. The result of this is that the plow can be operated safely without the need to make constant corrections for the knifing and without the added danger of the inattentive operator being pulled from the roadway or into oncoming traffic and causing property damage or personal injury.

Abstract: Safety apparatus for use in a moldboard assembly having a plurality of horizontally aligned trip blade units pivotally supported in the bottom of the moldboard frame so that the units move independently between a downwardly extended operative position and a rearwardly extended, fully tripped position. A biasing mechanism urges each unit into the operative position with a predetermined amount of force. A control mechanism further regulates the biasing force exerted on each unit so that the biasing force first increases as the unit moves out of the operative position and then decreases as the unit continues to move into the fully tripped position. The force exerted on each unit when in the fully tripped position is considerably less than that used to hold the unit in the operative position thereby preventing the assembly from lifting as it moves over an obstacle.
