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.
Claims22
A snowplow, comprising:
- a blade for displacing snow said blade having a front and back surface, said front surface being for accumulating snow to be displaced;
- a blade attaching support for operatively connecting said blade to a rear of a vehicle for towing said blade said blade attaching support having first and second portions, said first portion being for attaching to said vehicle and said second portion having said blade attached thereto, wherein said first and second portions are moveable with respect to one another such that said blade is capable of being moved between a raised position wherein said blade is not capable of plowing snow, and a lowered position wherein said blade is capable of plowing snow;
- a fulcrum attached to said support for manually moving said blade between said raised position and said lowered position, said blade moved respectively between said raised and lowered positions by manual force alone;
- and
- wherein said blade attaching support includes a pivotable lever and a slidable arm attached thereto so that when said slidable arm is operatively attached to said vehicle, said lever is capable of being moved so that said first portion is one of:
- more securely attached to said vehicle and less securely attached depending on a direction of movement of said lever.

A snowplow, comprising:
- a blade for displacing snow, said blade having a front and back surface, said front surface being for accumulating snow to be displaced;
- a blade attaching support for operatively connecting said blade to a rear of a vehicle for towing said blade, said blade attaching support having first and second portions, said first portion being for attaching to said vehicle and said second portion having said blade attached thereto, wherein said first and second portions are moveable with respect to one another such that said blade is capable of being moved between a raised position wherein said blade is not capable of plowing snow, and a lowered position wherein said blade is capable of plowing snow;
- a fulcrum attached to said support for manually moving said blade between said raised position and said lowered position, said blade moved respectively between said raised and lowered positions by manual force alone;
- and
- a trailer hitch adapter for connecting between a trailer hitch of said vehicle and said blade attaching support, wherein said adapter includes an open end for receipt of a free end of said blade attaching support into an interior of said adapter and said blade attaching support includes a pivotable lever and slidable arm attached thereto so that when said slidable arm is attached to said adapter, said lever is capable of being moved so that said free end moves relative to said interior.
