Abstract

A loading apparatus is coupleable to an engine-powered, wheeled machine, such as a snow blower or lawnmower, to aid in lifting the machine onto and off of raised platforms and up and down stairs. The loading apparatus includes a handle assembly having a first arm and a second arm, a first side support member having a first end sized to receive the first arm, and a second side support member having a first end sized to receive the second arm. The apparatus also includes attachment brackets coupled to respective upper portions of the first and second side support members, and attachment brackets coupled to respective lower portions of the first and second side support members. The first and second arms of the handle assembly slidably engage the first and second side support members and are moveable therein between a retracted position and an extended position.

8. The assembly of claim 7 wherein the machine comprises one of a snow blower and a lawnmower.

9. The assembly of claim 7 wherein the first and second arms of the second handle assembly slideably engage the first and second side support members and are moveable within the first and second side support members between the retracted position and the expanded position.

10. The assembly of claim 7 further comprising:

a first hinge coupling the first arm to the first side support member; and

a second hinge coupling the second arm to the second side support member; and

wherein the second handle assembly rotates about the first hinge and the second hinge when moving between the retracted position and the extended position.

11. The assembly of claim 7 further comprising a third handle assembly coupled to a front end of the housing of the machine.

12. The assembly of claim 7 wherein the first and second side support members comprise pointed ends.
